▼ H-relexes are used to determine the reflex connections of
muscle spindle afferents, the exitability of the motorneuron pool and the integrity of the reflex pathways. However, H-relexes are small and can be difficult to elicit in the
masseter, limiting their use in the investigation of the masticatory system. This study investigated the recruitment of
masseter motorneurons into the H-reflex, compared to the recruitment occuring during voluntary isometric biting, to determine the distribution of the effective
muscle spindle input.

▼ O padrão de contração de músculos pares pode ser investigado usando eletromiografia (EMG) de superfície. Isto torna possível saber quando e como um músculo é ativado e ainda determinar como se estabelece a coordenação de diferentes músculos envolvidos no movimento. Além disso, a influência da condição oclusal sobre a função estomatognática também pode ser avaliada por meio da eletromiografia. Este trabalho teve por objetivo analisar e descrever as características de coordenação e (as)simetria, nos músculos masseter e temporal anterior durante os testes estático e dinâmico em uma população brasileira de sujeitos jovens adultos saudáveis, assintomáticos para disfunção temporomandibular, por meio de um novo instrumento de registro eletromiográfico. Para isso, participaram da pesquisa 100 sujeitos. Todos realizaram o teste estático e 60 sujeitos foram selecionados para realizar o teste dinâmico da mandíbula. Os resultados demonstraram que os sujeitos jovens adultos avaliados apresentaram valores médios dos índices eletromiográficos dentro dos padrões de normalidade já estabelecidos previamente para outras populações. Este padrão de normalidade parece refletir em um bom desempenho funcional do sistema estomatognático, como o encontrado na avaliação miofuncional. Provavelmente os valores sejam válidos para a população brasileira, porém estudos com amostras mais numerosas deverão ser realizados.
The contraction pattern of paired muscles can be investigated using surface electromyography (EMG). This makes it possible to know when and how a muscle is activated as well as determine the coordination of different muscles involved in the movement. Furthermore, the influence of occlusal condition on the stomatognathic function can also be evaluated by electromyography. This study aimed to examine and describe the characteristics of coordination and (a)symmetry in the masseter and temporal muscles during the previous static and dynamic tests in a population of subjects young healthy adults, asymptomatic for temporomandibular dysfunction, using a new electromyographic instrument. For this, 100 subjects participated in the study. All performed the static test and 60 subjects were selected to perform the dynamic test of the jaw. The results showed that the young adults subjects evaluated showed average values of the electromyographic index within the normal range already set previously for other people. This pattern of normality seems to reflect a good performance of the stomatognathic system, as found in myofunctional evaluation. Probably the figures are valid for the Brazilian population, but studies with larger samples should be conducted.

▼ Este estudo analisou por meio de um eletromiógrafo de superfície as atividades dos músculos masseteres, direito e esquerdo, de 30 pacientes com diagnóstico de fratura de ossos da face, com uma média de 1,33 fraturas por paciente, em quatro momentos, no pré-operatório e nos pós-operatórios equivalentes ao 7°, 30° e 60° dias posteriores à cirurgia. Considerou-se o valor de cada medida, a média entre três contrações máximas isométricas voluntárias de duração de cinco segundos cada uma. Os paciente foram agrupados de acordo com o diagnóstico da fratura, sendo com fratura da mandíbula 50%, fratura do zigomático 33%, fratura da maxila 10% e com fraturas associadas 6,7%. Os pacientes apresentaram menor atividade dos músculo masseter no período pré-operatório, quando comparado a valores considerados normais, em todos os grupos de fraturas, seguida de queda acentuada no pós operatório de 07 dias, sendo que todos os grupos apresentaram recuperação da atividade em 60 dias, porém abaixo do valor normal encontrado na literatura. Os valores médio observados foram em ordem decrescente: fratura de zigomático, fratura de mandíbula, fratura de maxila e fraturas associadas. As fraturas de mandíbulas unilaterais apresentaram maiores valores que as fraturas bilaterais na maioria dos tempos. Houve diferença altamente significante na comparação da evolução da atividade do músculo masseter direito e esquerdo para as fraturas de mandíbula e de zigomático, sendo que na comparação par a par houve diferença significante entre a maioria dos grupos.
This study analyzed using a surface electromyographic activity of the masseter muscles, right and left, of 30 patients with fractures of facial bones, with an average of 1.33 fractures per patient, four times, the pre-operative and postoperative equivalent to the 7th, 30th and 60th days after surgery. It was considered the value of each measurement, the average of three isometric maximum voluntary contractions for five seconds each. Patients were grouped according to the diagnosis of fracture, 50% of the mandible fracture, 33% of the zygomatic fracture, 10% of maxilla fracture and 6,7% with associated fractures. The patients showed lower activity of the masseter muscle in the preoperative period, when compared to normal values in all groups of fractures, followed by a sharp drop in the postoperative period of 07 days, and all groups showed a recovery of activity in 60 days, but below the normal value found in the literature. The average values were observed in decreasing order: zygomatic fracture, mandible fracture, maxilla fracture and associated fractures. The unilateral jaw fractures showed higher values than the bilateral fractures in most of the times. There was a highly significant difference in comparing the evolution of the activity of the masseter muscle right and left to the mandibular and zygomatic fractures, if compared pairwise significant difference between most groups.

▼ Para melhor compreender a fisiopatologia que afeta a musculatura do sistema estomatognático, a análise eletromiográfica dos músculos da mastigação tem sido incluída em muitos estudos. A eletromiografia (EMG) permite verificar e avaliar a eficácia muscular, entre os músculos de ambos os lados do corpo (simetria) e entre pares de músculos, com um possível efeito de desvio lateral da mandíbula (torque) (Ferrario et al., 1999, 2002). O objetivo desse trabalho foi estudar por meio da EMG de superfície os músculos
masseter (porção superficial) e temporal (porção anterior) bilateralmente, e verificar o efeito do uso da placa oclusal resiliente, como um dos recursos para o tratamento das desordens temporomandibulares (DTMs), e comparar com um grupo controle. Foram envolvidos 23 indivíduos com sinais e sintomas de DTM, avaliados clinicamente, que receberam depois tratamento com placas oclusais resilientes. Para estabelecer a presença ou ausência de DTM, foi utilizado o Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD); além de registrar a atividade EMG dos músculos
masseter e temporal, bilateralmente, antes (inicial Etapa 1), 30 (Etapa 2) e 60 dias após o uso da placa oclusal resiliente (Etapa 3) (Pettengill et al., 1998); relacionar os achados eletromiográficos com a avaliação clínica da oclusão e das funções estomatognáticas; comparar os resultados de uma população com DTM e o grupo controle de 23 indivíduos. As avaliações EMG foram registradas por meio de movimentos de mastigação e das condições clínicas de repouso, lateralidade com contato bilateral, protrusão e apertamento dental. A análise estatística foi realizada com o emprego do software SPSS versão 15.0 (Chicago, IL, USA). Devido ao fato de que foi rejeitada a hipótese de normalidade da grande maioria das variáveis (Teste de Shapiro-Wilks) foram utilizados métodos não-paramétricos na análise. O nível de significância adotado foi p ≤0,05. Os dados dos grupos controle e DTM foram comparados por meio do teste não-paramétrico de Mann-Whitney, e as comparações intragrupo DTM (inicial, 30 e 60 dias de uso de placa) foram realizadas por meio do teste não-paramétrico de Wilcoxon. De acordo com os resultados, na condição clínica de repouso, não houve diferença estatisticamente significativa na comparação entre os grupos controle e DTM; e foi observado diferença estatisticamente significativa intra-grupo de DTM. Na condição clínica de lateralidade direita, houve diferença estatisticamente significativa na comparação entre os grupos controle e DTM, e na comparação intra-grupo de DTM, não houve diferença estatisticamente significativa. Entretanto, na condição clínica de lateralidade esquerda, não houve diferença estatisticamente significativa na comparação entre os grupos controle e DTM, e na comparação intra-grupo DTM. Na condição clínica de protrusão, na comparação entre os grupos controle e DTM, e na comparação intra-grupo de DTM, houve diferença estatisticamente significativa. Na condição clínica de apertamento de parafilme, houve diferença…

▼ The mouth, throat, and face contain numerous muscles that participate in a large variety of orofacial behaviors. The jaw and tongue can move independently, and thus require a high degree of coordination among the muscles that move them to prevent self-injury. However, different orofacial behaviors require distinct patterns of coordination between these muscles. The method through which motor control circuitry might coordinate this activity has yet to be determined. Electrophysiological, immunohistochemical, and retrograde tracing studies have attempted to identify populations of premotor neurons which directly send information to orofacial motoneurons in an effort to identify sources of coordination. Yet these studies have not provided a complete picture of the population of neurons which monosynaptically connect to jaw and tongue motoneurons. Additionally, while many of these studies have suggested that premotor neurons projecting to multiple motor pools may play a role in coordination of orofacial muscles, no clear functional roles for these neurons in the coordination of natural orofacial movements has been identified. In this dissertation, I took advantage of the recently developed monosynaptic rabies virus to trace the premotor circuits for the jaw-closing
masseter muscle and tongue-protruding genioglossus
muscle in the neonatal mouse, uncovering novel premotor inputs in the brainstem. Furthermore, these studies identified a set of neurons which form boutons onto motor neurons in multiple motor pools, providing a premotor substrate for orofacial coordination. I then combined a retrogradely traveling lentivirus with a split-intein mediated split-Cre recombinase system to isolate and manipulate a population of neurons which project to both left and right jaw-closing motor nuclei. I found that these bilaterally projecting neurons also innervate multiple other orofacial motor nuclei, premotor regions, and midbrain regions implicated in motor control. I anatomically and physiologically characterized these neurons and used optogenetic and chemicogenetic approaches to assess their role in natural jaw-closing behavior, specifically with reference to bilateral
masseter muscle electromyogram (EMG) activity. These studies identified a population of bilaterally projecting neurons in the supratrigeminal nucleus as essential for maintenance of an appropriate level of
masseter activation during natural chewing behavior in the freely moving mouse. Moreover, these studies uncovered two distinct roles of supratrigeminal bilaterally projecting neurons in bilaterally synchronized activation of
masseter muscles, and active balancing of bilateral
masseter muscle tone against an excitatory input. Together, these studies identify neurons which project to multiple motor nuclei as a mechanism by which the brain coordinates orofacial muscles during natural behavior.

This study aimed to investigate how the activity of the masseter (Mas) and suprahyoid (Hyoid) muscle are influenced by the condition of food, how changes in rheological property differ in the process of food reduction between different foods, and how different salivary flow rates affect bolus-making capability during chewing in healthy humans. Ten healthy adult males participated. Electromyographic (EMG) recordings were obtained in the Mas and Hyoid muscles, and 15 g steamed rice and rice cake were prepared as test foods. In the ingestion test, the subjects were asked to eat each food in their usual manner. The chewing duration, number of chewing cycles before the first swallow, Mas and Hyoid EMG activity, and chewing cycle time were compared between the foods. The chewing duration was divided into three substages: early, middle, and late; chewing cycle time and EMG activity per chewing cycle of each substage were compared between the foods and among the substages. In the spitting test, the rheological property of the bolus at the end of each substage was compared between the foods and among the substages. Finally, stimulated salivary flow rate was measured and the relationships between the salivary flow rate and chewing duration, EMG activity, changes in the physical properties, and EMG activity were investigated. There were significant differences in the chewing duration and number of chewing cycles between the foods with similar hardness, but not in the chewing cycle time. The Mas and Hyoid EMG activity per chewing cycle for the rice cake was significantly greater than for steamed rice throughout the recording periods. While the Mas activity did not change among the substages during chewing, the Hyoid EMG activity decreased as chewing progressed. Chewing cycle time also gradually decreased as chewing progressed. The hardness of both foods initially increased, then gradually decreased back to baseline. Adhesiveness of the rice cake initially increased, and did not fall throughout the recording period; adhesiveness did not significantly change for the steamed rice. Cohesiveness barely changed for the two foods during chewing, but was significantly greater for the rice cake than for steamed rice. Finally, a correlation between the stimulated salivary flow rate and chewing performance was noted only in change in Mas EMG activity. The current results demonstrate that the Mas and Hyoid muscle activity changed as chewing progressed, and was affected by hardness, adhesiveness, and cohesiveness. Salivary flow rate may affect the changes in Mas activity in the process of bolus formation.

▼ It has been suggested that architectural changes occur in masseter muscle (MM) in conditions of facial pain. To understand pathological changes, it is necessary to elucidate normal musculo-aponeurotic architecture. Muscle architecture is characterized by parameters including fiber bundle length (FBL) and height of aponeuroses. The purpose of this study was to investigate the architecture of MM volumetrically in 24 asymptomatic participants using ultrasound, in the relaxed and maximally contracted states. Masseter consisted of superficial (SH) and deep heads (DH), each arranged in laminae. Fiber bundles extended between superior and inferior aponeuroses and/or bone. Statistically significant differences were observed in mean FBL and in the mean height of aponeuroses between the relaxed and contracted states only in superficial laminae of SH. These results suggest there is differential contraction of the laminae of MM. Future comparison with pathologic subjects can be made based on the normative database established.

▼ Temporomandibular joint disorders (TMD) affect 5% to 12% of the population. Architectural changes may occur in the masticatory muscles; notably the masseter muscle (MM) in TMD. Without an understanding of the normal architecture of MM, it may be difficult to understand such changes in disease. Studies investigating the in vivo multilaminar MM architecture are scarce. The aim of this study was to evaluate the in vivo musculo-aponeurotic architecture of the superficial head of MM in asymptomatic individuals with ultrasound in excursive movements of the mandible. An ultrasound protocol was developed, and twenty-four participants’ MMs were scanned bilaterally. On protrusion and contralateral excursion, superficial laminae showed significant changes compared to the relaxed state; no significant difference was found in the deep lamina. On ipsilateral excursion, superficial and deep laminae showed significant changes. These findings suggest there are differential changes to the laminae of MM during mandibular protrusion and lateral excursion.

▼ Background and aims: The Pain Adaptation Model and the Vicious Cycle Theory are older theories of the effects of pain on motor activity. While some data sets are consistent with these theories, other data sets are not, and a number of new models (the Integrated Pain Adaptation Model; Theory of Motor Adaptation to Pain) have been proposed. Two of these models propose a reorganization of motor activity in pain. The aim of the present study was to determine whether experimental masseter muscle pain resulted in a change in muscle activity at two different sites within the masseter muscle during the performance of isometric jaw-closing tasks in asymptomatic participants. Methods: Single motor unit (SMU) activity was recorded with bipolar fine wire electrodes at 2 sites within the right masseter muscle during the performance of standardized isometric biting on an intraoral force transducer in 17 healthy participants. Participants performed standardized biting trials during infusion of 5% hypertonic saline into the right masseter (pain), and during isotonic saline infusion (control). Recruitment patterns, force thresholds and firing rates were compared between pain and control trials. Results: A total of 50 SMUs were discriminated from the 2 sites. Changes in recruitment patterns of SMUs at one site within the masseter muscle during pain in comparison with control was observed during the tasks and some of these changes were different to the changes occurring at the other site. There were no changes in thresholds of SMU firing nor in SMU firing rates between pain and control trials. Inter-individual variability in the motor response to pain was observed at the two different sites of the masseter. Discussion and Conclusions: In general, the data are not consistent with the earlier models of pain-motor interactions, but provide support for more recent models proposing a re-organization of motor activity in the presence of pain.

▼ The human masseter muscle is a structurally complex jaw elevator with the capability of generating high, multidirectional forces. The invasiveness of current anatomical and physiological methods has, however, limited both the number and scope of studies of human masseter muscle structure and function. Therefore the aim of this work was to apply in vivo magnetic resonance (MR) techniques to elucidate the three-dimensional internal architecture of the human masseter muscle and its metabolic response to exercise in order to gain a better understanding of the jaw muscles in health and disease.
In the first of these experiments, five adult subjects were selected and examined using cephalometric radiography, magnetic resonance imaging (MRI) and three-dimensional rotational and reconstructive computer graphics to describe the organization of tendon planes within the masseter muscle. Planar quadrilaterals representing putative tendon planes were fitted to the surfaces of the three-dimensional muscle reconstructions, and these were related to the mid-sagittal plane in the coronal and axial views. To confirm whether putative planes disclosed by MRI represented true anatomic entities, a fresh human cadaver head was imaged by MRI and then cryosectioned at millimetre intervals. Planar sections through the reconstructed muscle generated from the cadaver cryosections were correlated with the actual MR images in the same planes. Tendon plane angulation appeared to be related to ramal length and lower face height measured cephalometrically. In the axial view, the tendon planes appeared roughly to follow the angulations of the zygomatic arch and the lateral face of the mandibular ramus. Our results suggest that the angulation of tendon planes, and possibly pennation angles are different depending on the viewing angle, and infer that muscle fibres inserting on either side of a central tendon may need to develop different tensile forces if translation is to occur directly along the tendon axis.
In the second, 31P magnetic resonance spectroscopy (MRS) was utilized to examine the masseter muscles of six adult males at rest and performing stereotyped isometric clenching exercises. 31P MR spectra were acquired from three locations within the muscle
using a 2cm by 3cm, single-turn, copper receiver coil. The spectra were quantified on the
basis of relative peak area and position. The organic phosphate (Pi) to creatine phosphate
(PCr) ratio (Pi/PCr), which has been shown to be proportional to free ADP concentration
and hence, the metabolic activity, as well as the normalized Pi concentration ([Pi]) and pH,
were calculated for each site and exercise. The mean resting Pi/PCr ratio and [Pi] were
greater for the deep part of the muscle than for the superficial and intermediate parts. These
differences were significant to p<0.01. The mean pH however, was similar in all parts of the
muscle at rest. During exercise, a significant increase in mean Pi/PCr was found in the
superficial and intermediate parts of the muscle. Both these differences were…

▼ There is a dearth of knowledge on the functional organization of the anatomically complex human masseter muscle. Limited physiological studies suggest a functional organization which may differ significantly from human limb muscles. The present studies aimed to examine the putative relationship between structure and function in the human masseter muscle as a basis for understanding function and dysfunction in human jaw muscles.
In the first experiment single motor unit (SMU) activity was recorded from pairs of recording sites distributed throughout the masseter muscle. In each case SMU activity at a chosen location was used as a reference to search for synchronized SMU activity at another selected site. The locations of the needle tips were estimated in 3-dimensions (3-D) by means of an optical system, then transferred to 3-D reconstructions derived from Magnetic Resonance images. This approach permitted calculation of the linear distances between verified muscle recording sites. The mean separation of the sites from which synchronous SMU activity could be recorded was 8.8±3.4mm. The putative territories had a preferred orientation in the antero-posterior axis. Motor unit territories were larger than described previously, and appeared to be related to anatomical compartments.
The second experiment involved recording activity from stereotactically mapped masseter SMUs. In each case, the lowest sustainable firing frequency (LSFF) was reached by slow increases and decreases in voluntary firing rate, followed by sustained firing at the lowest possible rate. Pulse-discrimination and digital sampling of consecutive inter-spike intervals (ISIs) were then used to measure LSFF for 2-6 separate occlusal and postural tasks to which each unit contributed. There were significant differences between mean ISIs for the tasks performed by most units, which suggests descending drive to masseter units is highly task-dependent. There were also regional differences in unit task specificities.
In the third paradigm, reflex SMU activity was recorded from units in the masseter muscle and the inferior head of the lateral pterygoid muscle. Bipolar electrodes fixed to the gingiva near the maxillary canine delivered single pulses of 1ms duration at sub-noxious levels of intensity. At constrained firing frequencies (10, 15Hz), pulses were injected sequentially, with increasing delays, after preselected spikes. More profound inhibition occurred in units firing at 10 than 15Hz. There were significant differences in masseter inhibitory responses when the unit task varied. Reflex inhibition in masseter and lateral pterygoid SMUs is highly frequency-dependent, and also task-dependent in masseter units.
The fourth study involved recording activity from SMUs in the masseter muscle. A midline load cell was fixed to the incisor teeth and aligned either perpendicular (P) or 30 degrees anterior (A) to the occlusal plane, without altering jaw position. A rigid spike-triggered averaging (STA) paradigm was used to extract the contribution of individual…

▼ Myofascial pain associated with temporomandibular disorders has often been linked to pathological muscle hyperactivity. As a result, localised disturbances of intramuscular blood flow could lead to a lower level of oxygen distribution, hypoxia and microcirculatory changes. To assess haemodynamic changes in the masseter muscle during sustained elevated muscle activity (SEMA). Sixteen healthy participants performed thirty 1-min bouts of SEMA with intervals of 1-min ‘rest’ periods between the bouts on a bite force transducer device. The participants completed three sessions with different percentage of their maximal voluntary occlusal bite force (MVOBF): 0% (no task), 10% or 40% MVOBF tasks. The order of the sessions was randomised with 1- to 2-week intervals. Haemodynamic characteristics of the masseter muscle were estimated with use of a laser blood oxygenation monitor. Tissue blood oxygen saturation (StO2) during SEMA was lower than during rest (P < 0·001). The relative changes in total haemoglobin (Total-Hb) and StO2 were influenced by condition (SEMA and rest) and with interactions between condition and session (0%, 10% and 40% MVOBF tasks). These results suggest that SEMA may lead to hypoxia in the masseter muscle and that the haemodynamic characteristics and muscle symptoms depend on the magnitude of muscle contractions. Overall, the present findings may help to provide better insights into relationships between jaw muscle activity, haemodynamic changes and symptom developments with implications for clinical conditions such as bruxism characterised by different levels of tooth-grinding and tooth-clenching muscle activity.

▼ Introdução: a paralisia facial periférica (PFP) é caracterizada por lesão geralmente unilateral do nervo facial em qualquer parte de seu trajeto. Na paralisia total há perda dos movimentos de todos os segmentos da hemiface ipsilateral à lesão. Clinicamente observa-se que a maioria dos pacientes com PFP em fase flácida apresenta dificuldade para mastigar do lado paralisado, pois a manutenção dos alimentos entre as arcadas dentárias está comprometida pela falta de participação do músculo bucinador. Aliada a isso pode ocorrer incompetência labial devido à flacidez da hemiface afetada em conseqüência à queda da comissura labial ipsilateral. Objetivo: verificar as conseqüências da PFP unilateral na fase flácida, com duração de pelo menos seis meses, na função mastigatória quanto a preferência clínica mastigatória e diferença eletromiográfica entre os masseteres.Casuística e Método: foram selecionados 27 indivíduos de ambos os gêneros, com PFP em fase flácida com pelo menos seis meses de paralisia, com idade entre 16 anos e 67 anos, com dentição natural permanente, selecionados por um protocolo específico, complementado com exame clínico miofuncional e avaliação eletromiográfica de superfície nos músculos masseteres nas provas de aperto dentário e mastigação habitual. Resultados: de acordo com as respostas da anamnese, 77,8% dos pacientes referiram mastigar preferencialmente do lado sadio. Clinicamente, 70% apresentaram preferência mastigatória. A atividade muscular dos bucinadores e orbicular da boca foi estatisticamente significante (p = 0,025) entre os lados sadio e paralisado. Apenas, 22,2% dos pacientes apresentou diminuição de massa do masseter do lado paralisado. Não houve diferença eletromiográfica estatisticamente significante entre os lados sadio e paralisado nos masseteres. Conclusão: no presente estudo, pacientes com PFP unilateral na fase flácida, com duração de pelo menos seis meses, apresentaram preferência clínica mastigatória pelo lado sadio. Não houve diferença clínica e eletromiográfica entre os lados paralisado e sadio nos músculos masseteres
Introduction: peripheral facial paralysis (PFP) usually affects the facial nerve in part or in whole on one side of the face. Most patients with PFP find it difficult to chew on the paralyzed side, especially due to compromised buccinator function. In addition, the sagging of the ipsilateral lip commissure tends to compromise lip competence. In spite of the importance of these associations, the literature on mastication difficulties in PFP patients is scarce, perhaps because the facial nerve has conventionally been considered to be responsible primarily for facial expression. Objective: to evaluate the impact of long-standing peripheral facial nerve paralysis upon mastication, regarding to clinical mastication preference besides clinical and electromyographic activity of the masseters. Method: the study included 27 male and female subjects aged 1669 years with permanent natural dentition and long-standing PFP. Patients answered questions on their mastication…

▼ Nos dias atuais, uma significante parte da população nacional pode apresentar alterações da relação maxilo-mandibular, chamada de má oclusão. A principal alteração do crescimento facial encontrado nos adultos é a deficiência transversal da maxila. A correção desta deficiência é realizada por um procedimento cirúrgico denominado de expansão rápida da maxila cirurgicamente assistida. Estas cirurgias causam uma mudança na atividade muscular, principalmente naqueles músculos responsáveis pelo fechamento mandibular, no qual se destaca o músculo masseter. Estas alterações musculares duram em média 30 dias, quando clinicamente note-se a diminuição da força ou potencial muscular de fechamento mandibular. Verificam-se os efeitos da expansão rápida de maxila sobre os músculos masséteres dos pacientes, avaliando resultados obtidos por eletromiografia de superfície. Realizaram quatro avaliações, no 7° dia pré-operatório e no 7°, 30° e 60° dia pós-operatório, em 20 pacientes, durante a contração máxima voluntária isométrica sobre um rolete de algodão. Comprovou-se que a atividade do músculo apresentou diminuição no 7° dia pós-operatório para 13,7% da sua atividade inicial. Nos 30º e 60º dias após a cirurgia, observou-se a recuperação até 26,7% e 94,9% de sua atividade inicial, respectivamente.
Nowadays, a significant part of the national population presents alterations of the maxilomandibular relationship, denominated bad occlusion. The main alteration of the facial growth found in the adults is the transverse deficiency of maxillary. The correction of this deficiency is accomplished through a surgical procedure denominated. These surgeries cause a change in the muscular activity, mainly in those muscles responsible for closing mandible, in which stands out the masséter muscle. These muscular alterations last 30 days on average, where clinically it is noticed the decrease of the force or muscular potential of closing the jaw. This work evaluates, through the electromyography exam, the effects of the surgical assisted rapid maxillary expansion on the patientsḿuscles masseters. Twenty patients were evaluated four times: 7 days before surgery; and 7, 30 and 60 days after surgery. The evaluation was done during the maximum voluntary isometric contraction on a cotton piece. The activity of the muscle diminished 7 days after surgery to 13, 7% of the initial activity. Nevertheless, 30 and 60 days after surgery, there was a recovery to 26, 7 and 94, 9%, respectively.

▼ A cirurgia de terceiro molar é um dos procedimentos mais realizados na área de cirurgia e traumatologia bucomaxilofaciais. A evolução pós-cirúrgica era baseada em evidência clínica. No nosso trabalho, propusemos acompanhar a evolução pós-cirúrgica através da utilização do eletromiografia de superfície. Realizamos quatro tomadas, no pré-operatório, normalizando, e três no pós-operatório, 7, 14, 21 dias, em amostra de 30 pacientes. Observamos, no vigésimo primeiro dia, recuperação próxima da normalização no gênero feminino e ainda aquém no gênero masculino. Constatamos que a eletromiografia de superfície é sensível para controle da evolução pós-cirúrgica, demonstrando ser um método eficaz e seguro.
The third molar surgery is one of the most frenquently performed procedures in the buccal-maxillary-facial traumatology and surgery areas, whereas the post-surgery evolution has been based on the clinical evidence until now. In our study, we proposed to analyze the post-surgery clinical evolution through the use of electromyograph of surface. We have made four takes, on the presurgery, normalizing, and three on the 7, 14 and 21 postoperative days, in a sample of 30 patients. We observed, in the twentieth-first day, a recovery close to normalization on women, but men did not reach normalization. The electromyograph of surface is sensitive to the post-surgery evolution control, and is an efficient and safe method.

▼ Abstract: Stress and tooth loss have an impact on the masticatory muscles favoring the pain. However, the pathogenesis involved is still little understood. The aim of this study was to investigate the effect of varied chronic stress in left
masseter muscle of rats subjected to unilateral alteration by occlusal tooth extraction, alone or associated, through evaluation of total gelatinolytic activities and myeloperoxidase, morphological analysis, histochemical, immunohistochemical labeling and transmission electron microscope. Twenty male Wistar rats, young adults, weighing ± 200 g, were divided randomly into four groups (n=5): GI control without occlusal alteration and without varied chronic stress (EV), G II-occlusal alteration isolated, G III EV isolated and G IV-occlusal alteration associated with the EV. The rats from groups of dental extraction (GII and G IV) were previously anesthetized and had the superior left molars extracted. The groups of stresses (G III and G IV) were submitted to different stressors from the 14th day after the tooth extraction. All the animals were euthanized on the 24th day. On the surface, the beam analysis of results showed that the
masseter muscle, dental extraction and the EV, alone or associated with not promoted the infiltration of polymorphonuclear scanned through the myeloperoxidase and not altered levels of metalloproteinases (MMP-2) evaluated by means of Total Gelatinase activity. In the anterior bundle of
masseter muscle located evaluated through the Total Gelatinase activity. In anterior bundle of the deep
masseter muscle, the dental extraction and the EV, alone or associated with altered, in some regions, the histological characteristics of the fibers revealed by hematoxylin and eosin staining; the ultrastructure of mitochondria in the transmission electron microscope; revealed areas with reduced lumen, and lumen distended in other capillaries marked with anti-laminina antibody; showed a tendency to increase in the density of capillaries labelled by endothelium, CD31 anti-alpha and have not altered the scarce labelled fibers by myosin type I in the same bundle, decreased levels of reactive oxygen species in the group exposed to dental extraction (GII). The average bundle of deep
masseter muscle later, experimental protocols confirmed the prevalence of clear fibers by means of Immunohistochemistry reaction of succinate dehydrogenase. We can conclude that the
masseter muscle change resulting from regional expressed left dental extraction and EV alone or associated, revealed by morphological, ultrastructural, and hemodynamic oxidative stress, especially in deep beam. These data contribute to the understanding of the development of the trigger point. However, further studies are needed to better understanding of the pathogenesis of myofascial pain and temporomandibular joint dysfunction and its relation with occlusal stress and occlusial alteration

▼ A eletromiografia de superfície (EMG) pode ser considerada atualmente um instrumento muito útil, que permite a avaliação quantitativa da musculatura de pacientes com desordem temporomandibular (DTM). O propósito do presente estudo foi aplicar e analisar os efeitos do protocolo FARC de tratamento de DTM com placa oclusal e controle eletromiográfico, comparando os dados da avaliação, de 15 pacientes com DTM, classificados segundo o RDC / TMD, antes e após o tratamento; os resultados da EMG obtidos antes, durante e após o uso da placa por 45 dias, pelo grupo com DTM; e comparando os resultados da EMG de uma população com DTM antes e após o tratamento com placa, com um grupo controle. O exame eletromiográfico dos músculos
masseter e temporal anterior foi realizado na primeira sessão de avaliação (Etapa 1), após 1 semana (Etapa 2) e após 5 semanas (Etapa 3) de tratamento, servindo para verificar a estabilidade da placa e a evolução da atividade muscular. As ondas da EMG foram analisadas, por meio do software, e os seguintes índices de EMG foram computados: coeficiente de porcentagem de sobreposição (POC) dos músculos
masseter e temporal; coeficiente de torque (TORS); índice de assimetria (ASIM), índice de atividade (ATTIV) e o total da atividade elétrica (IMP). Para os dados expressos em nível intervalar de mensuração, foi empregada estatística não-paramétrica, sendo empregado o teste de Wilcoxon para dados pareados nas análises intra-grupo (entre as etapas). Os dados em nível de razão, foram analisados por meio de estatística paramétrica, sendo empregados para as análises intra-grupo o teste t para dados pareados, para as análises entre grupos o teste t para amostras independentes. O nível de significância estabelecido foi de 5%. Após o tratamento, foi encontrada diferença estatística na capacidade de abertura da boca, assim como na remissão da dor a palpação de grande parte da musculatura avaliada e na ATM. Foi obtida diferença significante no valor de POC do
masseter e de IMP, imediatamente após o primeiro ajuste da placa. Quando comparada a etapa 1, sem a placa, com a etapa 2, com a placa ajustada, foi obtida diferença significante nos valores de POC do
masseter, de ASIM e de IMP. Houve diferença significante entre as etapas 1, sem placa, e a etapa 3, com placa, nos valores de POC dos músculos
masseter e temporal, de ASIM, ATTIV e IMP. Durante todo o tratamento não houve diferença significativa nos índices de EMG dos exames realizados sem a placa. Houve diferença estatística entre os grupos DTM e controle no início e ao final do tratamento, sendo observada diferença significante nos valores de EMG para POC de ambos os músculos e ATTIV. A placa oclusal, embora não tenha mostrado mudanças permanentes, mostrou ser efetiva para promover equilíbrio das atividades da EMG durante seu uso, e eficiente no alívio dos sintomas. Os parâmetros de pesquisa com EMG permitiram seu uso no âmbito cientifico na identificação do desequilíbrio neuromuscular, desta forma este instrumento de avaliação permitiu analisar e avaliar de forma…

▼ Abstract: The aim of this study was to evaluate the interday and intraday variability in the values of electromyographic recordings of the superficial part of the
masseter muscle and anterior part of the temporal
muscle. Besides, it also purposed to verify the relationship of these recordings with the emotional factors, anxiety, at three different days of data collection. Sixteen volunteers, free of signs and symptoms of temporomandibular desorder, according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were selected. Cephalometric measurements in lateral teleradiographs were used to classify the subjects into Class I and II, according to the relationship of maxillo-mandibular bone bases and regarding considering the vertical dimensions of the face into distinct mesofacial and dolicofacial types. To measure anxiety, the State-Trait Anxiety Inventory (STAI) was used. The electromyographic exam was carried out with Myosystem Br 1â electromyograph of 12 channels, with a resolution of 12 bites and gain up to 50 times, sampling frequency of 4000 Hz, bipolar passive electrodes coupled to a pre-amplifier with 20 times gain. The tasks of simultaneous bilateral chewing, habitual chewing and voluntary contraction in maximum intercuspidation were performed, at three different days, with interval of one week among them, and three repetitions on each day. The electromyographic signals were processed and normalized, and then the electrical activity of assessed muscles during the tasks were calculated through the instant maximum (Imax) and the time of activation (ON) the software Matlab version 5.3. As results, there was a variability between the comparison of the average of variable ON of the right
masseter muscle in the habitual chewing on the various days of collection (p=0.02). While evaluating simultaneous bilateral chewing variability between the comparison of the average of variable ON of the anterior part of the right temporal
muscle in the various repetitions (p=0.03). Given the variability shown by these muscles, there is a need to evaluate the electromyographic records both in habitual chewing and in the simultaneous bilateral chewing of these muscles in more than one session and more than one repetition. Regarding to anxiety, the results showed a reverse association between the variable activation time and the levels of trait-anxiety during the two tasks, and a direct association between the variable Imax and the levels of trait-anxiety during the two tasks. Only the anterior part of the temporal
muscle during habitual chewing presented a direct relationship between the variable Imax and state-anxiety; and during simultaneous bilateral chewing the variable ON showed a reverse relationship for the same
muscle. Thus it was concluded that the trait and state anxiety can influence electromyographic records, even in non-experimental situations.

▼ Abstract: The loss of dental elements is an important factor in stomatognathic system dysfunctions and consequential damage to the masticatory muscles. The aim of this study was to analyze the morphometric and ultrastructural changes of the pterygoid medial(PTM) and
masseter muscle, under occlusal defects, induced by unilateral left molar extraction, of Wistar rats. Thirty-six male rats were used: 24 for light microscopy (LM) and 12 for transmission electron microscopy analysis (TEM), divided into three experimental groups (GI-15; GII-30 and GIII-60 days), containing 5 animals each for LM with 3 control and 3 for TEM with one animal control for each period. Morphometric studies were made measuring the area of PTM and
Masseter muscle fibers ipsi and contralateral to dental extraction, using a digital program. A qualitative analysis was performed to evaluate the ultrastructural findings and of the PTM and
Masseter muscle. The results were compared using ANOVA test. There was a reduction of area of PTM of animals undergoing tooth extraction, both ipsi as contralateral. Both sides were similar when compared with each other, as assessed in the various evolutive periods. Differences were observed in the fiber area, especially in the first group and these showed progressive increase, reaching their highest average in GIII. No difference was detected regarding the morphometric analysis of the
masseter muscle. For ultrastructure observed asymmetry and disorganization of Z line and I band, only the experimental group GII,
muscle PTM. The analysis of the collagen fibers showed that the
muscle fascicles are lined by a delicate network of collagen type I and type III, with a predominance of the latter (reticular fibers), in the
masseter, in different evolutionary periods. Temporomandibular joint dysfunction, promoted by unilateral molar extraction in wistar rats, can lead to morphometric changes ipsi and contralateral with reduction of areas, particularly in the PTM. However seem to adapt to new conditions throughout the experiment. The band Z and the ith row of the
muscle cytoskeleton are the most sensitive to this, dysfunction in
muscle PTM, however ephemeral, since it was observed only in the Group (GII) with 30 days of the experiment. The
muscle PTM proved to be more vulnerable in this experimental model, probably for its own functional features and greater participation in the dynamics of the masticatory movements, compared to the
Masseter. The collagen fibers of type I and type III are the major constituents of the connective fibrous tissue structures of these muscles, with a predominance of type III in the
Masseter and doesn't seem to be affected, to this procedure

▼ Objectives: Previous studies in the Oral Neurophysiology Laboratories in Dundee have defined the electromyographic properties of the inhibitory jaw reflex that can be evoked in human subjects by electrical stimulation of the lip. This reflex, in contrast with the more widely studied biphasic inhibitory reflexes evoked by stimulation of intra-oral nerves, consists of just a single phase of inhibition and usually requires the application of stimuli which excite nociceptive nerves. The aims of the present studies were to define the mechanical manifestations of this reflex in the form of changes in biting forces, and to investigate whether the mechanical manifestation of the inhibitory jaw reflex evoked by stimulation of the human upper lip, can be modulated by experimentally-controlled conditions that mimic symptoms of a myogenous temporomandibular disorder. Methods: Three series of experiments were performed on 49 volunteer subjects in total. The experiments involved recording bite forces between the anterior teeth and electromyograms (EMGs) from the masseter muscles. Transcutaneous electrical stimuli were applied to the hairy skin of upper lip while the subjects maintained a biting force of around 50N with the aid of visual feedback. In the first series of experiments, a range of electrical stimuli below and above the nociceptive threshold was delivered. In the second set of experiments, double stimuli with a range of different inter-stimulus intervals were applied. Finally in a third series of experiments, electrical stimulation was repeated before, immediately after, and 5 and 10 minutes following a 3-minute accelerated chewing task. This task consisted of chewing 1.5g of a tough chewing gum at 1.5 times the subject’s natural chewing rate and in 18 cases, muscle fatigue and/or pain were reported by the subjects. Results: Following stimulation at intensities that were described as sharp or painful, all the subjects showed both a suppression of the masseter EMG and a reduction of biting force. When analysing the maximum responses in each subject, the mean reduction in the EMG inhibition was to 15.78 ± 14.4% and 10.39 ± 7.92% of the baseline (for the ipsi- and contra-lateral EMGs respectively), whereas the biting force was reduced only to 83.98 ± 11.04% of baseline (+ S.D.). The latencies of onset of these responses were: 38.17 ± 3.58ms, 38.97 ± 4.49ms and 51.83 ± 6.23ms respectively. The response observed in the force record was weaker than in that observed in either EMG (Paired t tests, P < 0.005 in both cases). When applying double stimuli, it was found that the prolongation of the EMG inhibitory jaw reflex (to 144.70 ± 46.93% of the control level) evoked by double stimulation of the upper lip (with a 10 ms inter-stimulus interval) resulted in a greater increase in the depth of the accompanied relaxation (to 223.63 ± 70.88% of that seen in the control responses) compared to a relatively smaller increase in the duration of the relaxation (to 128.32 ± 27.23% of that seen in the control responses). Following the…

▼ OBJECTIVE: This study was conducted to determine if interleukin-6 (IL-6) and interleukin-1beta (IL-1beta) mRNA expression increase in response to muscle contraction caused by repetitive electrical stimulation of the rat masseter muscle. METHODS: Male Wistar rats weighing 140-160 g were divided randomly into the following three groups: electrical stimulation (ES) group (n=21), carrageenan injection (CI) group (n=24), and ES under dantrolene sodium (muscle relaxant) injection (ESDI) group (n=7). ES or CI was done to the left masseter; and mock ES or mock CI to the right. Muscle tissues on both sides were sampled for total RNA isolation. Real-time RT-PCR was performed, with the cyclophilin A (CypA) mRNA level in each sample as an internal control. Mean relative IL-6 (il-6/cypA) and IL-1beta (il-1beta/cypA) mRNA levels were compared between the experimental and mock-treated sides within each group. RESULTS: Mean IL-6/CypA levels in the ES- or CI-treated muscle significantly increased, without any significant incremental change observed in either mock-treated muscle. Interestingly, the increase in the il-6/cypA level caused by the ES was suppressed by the injection of dantrolene sodium in the ESDI group. Furthermore, the mean il-1beta/cypA level in the CI-treated masseter also significantly increased without any significant incremental change observed in the mock-treated muscle. However, there was no significant difference in the mean il-1beta/cypA levels in the masseter between the ES- and the mock-treated sides. CONCLUSIONS: These results show that IL-6 mRNA expression in the rat masseter muscle was accelerated by the CI or by repetitive muscle contraction induced by ES. Since the mRNA level of IL-1beta, a well-known proinflammatory cytokine, was not altered by the contraction, the accelerated IL-6 mRNA expression elicited by the muscle contraction does not seem to be related to local inflammation.

▼ There is some evidence suggesting that obstructive sleep apnea-hypopnea syndrome (OSAHS) is concomitant with sleep bruxism (SB). The aim of this study was to investigate the temporal association between sleep apnea-hypopnea events and SB events (AHEs & SBEs). In an open observational study, data were gathered from 10 male subjects with confirmed OSAHS and concomitant SB. Polysomnography and audio-video recordings were performed for one night in a sleep laboratory. Breathing, brain, heart, and masticatory muscle activity signals were analyzed to quantify sleep and sleep stage duration and number and temporal distribution of AHEs and SBEs. AHEs were collected within a 5-minute time window before and after SBEs, with the SBE as the pivotal reference point. Two temporal patterns were analyzed: 1) the interval between AHE termination and SBE onset, called T1, and 2) the interval between SBE termination and AHE onset, called T2. Of the intervals between SBEs and the nearest AHE, 80.5% were scored within 5 minutes. Most intervals were distributed within a period of less than 30 seconds, with peak at 0 to 10 seconds. The T1 interval had a mean length of 33.4 seconds and was significantly shorter than the T2 interval (64.0 seconds;p<0.05). Significantly more SBEs were scored in association with the T1 than the T2 pattern (p<0.05). Thus, in patients with concomitant obstructive sleep apnea-hypopnea syndrome and sleep 2 bruxism, most sleep bruxism events occurred after sleep apnea-hypopnea events, suggesting that sleep bruxism event occurring close to sleep apnea-hypopnea event is a secondary form of sleep bruxism.

▼ Background: Registering a true maximum bite force on the most commonly-used force transducers is problematic. It is often believed that this is related mainly to discomfort and the fear of breaking teeth. Objectives: The aim of the project was to compare the suitability of different bite force measuring transducers including ones which were designed to improve subject comfort. The transducers used were a traditional strain-gauge transducer with and without covering with ethylene vinyl acetate (EVA) sheets, and a newly-developed pressure transducer. Methods: Five separate studies were performed in this project. The experiments were carried out on human volunteer subjects (aged 24 to 41 years). They were all dentate with no missing anterior teeth and with no crowns on these teeth. The following procedures were used in some or all of the studies: measurement of MVBF, electrical stimulation of the masseter muscle, and EMG recording from two pairs of jaw closing muscles. Results: The highest MVBF values were recorded on the pressure transducer, mean (± S.D.) 464 N ± 224 N; followed by the strain-gauge transducer with EVA sheets, 243 ± 80 N; and last of all the strain-gauge transducer with silicone indices, 165 ± 35 N; or acrylic indices, 163 ± 82 N. Significantly higher maximum potential bite forces were predicted by twitch interpolation for the pressure transducer (730 ± 199 N) than for the strain-gauge transducer with EVA sheets, 354 ± 67 N (Paired t test, P < 0.05). Significantly higher EMGs of the masseter and anterior temporalis muscles were found to be associated with MVBFs on the pressure transducer than with MVBFs on the strain-gauge transducer with EVA sheets (Paired t test, P < 0.05). Conclusions: It is concluded that: a) the pressure transducer system and to a lesser extent the strain-gauge transducer covered with EVA sheets seemed to overcome the fear associated with biting on the hard surfaces of the strain-gauge transducer alone; b) the pressure transducer may have some multi-directional capabilities which allow for total bite forces, or at least larger parts of them, to be recorded than on a uni-directional strain-gauge transducer.

▼ There is some evidence suggesting that obstructive sleep apnea-hypopnea syndrome (OSAHS) is concomitant with sleep bruxism (SB). The aim of this study was to investigate the temporal association between sleep apnea-hypopnea events and SB events (AHEs & SBEs). In an open observational study, data were gathered from 10 male subjects with confirmed OSAHS and concomitant SB. Polysomnography and audio-video recordings were performed for one night in a sleep laboratory. Breathing, brain, heart, and masticatory
muscle activity signals were analyzed to quantify sleep and sleep stage duration and number and temporal distribution of AHEs and SBEs. AHEs were collected within a 5-minute time window before and after SBEs, with the SBE as the pivotal reference point. Two temporal patterns were analyzed: 1) the interval between AHE termination and SBE onset, called T1, and 2) the interval between SBE termination and AHE onset, called T2. Of the intervals between SBEs and the nearest AHE, 80.5% were scored within 5 minutes. Most intervals were distributed within a period of less than 30 seconds, with peak at 0 to 10 seconds. The T1 interval had a mean length of 33.4 seconds and was significantly shorter than the T2 interval (64.0 seconds;p<0.05). Significantly more SBEs were scored in association with the T1 than the T2 pattern (p<0.05). Thus, in patients with concomitant obstructive sleep apnea-hypopnea syndrome and sleep 2 bruxism, most sleep bruxism events occurred after sleep apnea-hypopnea events, suggesting that sleep bruxism event occurring close to sleep apnea-hypopnea event is a secondary form of sleep bruxism.

▼ A cirurgia de terceiro molar é um dos procedimentos mais realizados na área de cirurgia e traumatologia bucomaxilofaciais, e buscando um aumento na velocidade da recuperação pós-cirúrgica, muitos recursos fisioterápicos são empregados, entre eles a laserterapia e o acompanhamento da evolução pode ser baseado em evidência clínica. Neste trabalho, foi proposto acompanhar a evolução pós-cirúrgica através da utilização do eletromiografia de superfície em dois grupos distintos: pacientes sem fisioterapia com laser no pós-operatório e pacientes tratados no pós-cirúrgico com laserterapia. Realizamos quatro tomadas, no pré-operatório, normalizando, e três no pósoperatório, 7, 14, 21 dias, em amostra de 60 pacientes. Observamos, que no sétimo dia no grupo onde houve a aplicação do laser de baixa intensidade 23,3% dos pacientes ja haviam recuperado sua atividade muscular do préoperatório contra apenas 3,3% do grupo controle, ja no décimo quarto dia 73,3% contra 6,7% do grupo controle e no vigésimo primeiro dia 80% contra 10% do grupo controle. Constatamos através da eletromiografia de superfície que a utilização do laser de baixa intensidade acelera significativamente a recuperação muscular pós-trauma cirúrgico
The surgery for extraction of the retained inferior third molar is one of the most commonly performed procedures in the field of maxillofacial surgery and traumatology. With the aim of accelerating the post-surgical recovery, many physiotherapy resources are employed, including laser therapy and its evolution was based on clinical evidence. In this study, we proposed to monitor the post-surgical evolution by using surface electromyography in two distinct groups of patients, treated or not with laser therapy postoperatively. In a sample of 60 patients, we held four evaluations: preoperatively, normalizing, and three times after surgery, at 7, 14, and 21 days postoperatively. On the seventh day, 23.3% of the patients in the group receiving low intensity laser had already regained their muscle activity as they presented preoperatively, versus only 3.3% of the control group. In the fourteenth day, this happened with 73.3% of treated patients versus 6.7% in the control group, and in the twenty-first day, 80% versus 10% in the control group. It was verified, by surface electromyography evaluation, that the use of low intensity laser significantly accelerates muscle recovery after surgical trauma

▼ Embriologicamente, o tecido ósseo surge posteriormente aos músculos. A musculatura temporomandibular e facial apresentam-se definidas quando da ossificação da face e crânio, com os ossos se desenvolvendo dentro de um envelope de músculo e fascia. Quando contrações ativas se iniciam em um músculo, ele passa a exercer contínuo efeito sobre os ossos aos quais pertencem sua origem e inserção. O tecido ósseo é tido como um dos mais plásticos e responde prontamente às forças e tensões geradas pelos músculos. Evidenciase que os músculos, desde a fase pré-natal, desempenham papel na conformação dos ossos, e continuam a direcionar o crescimento pelo efeito de suas funções. Oito pacientes (4? e 4?) com idade entre 7 e 12 anos, com maloclusão dental classe III de Angle, foram submetidos a registros eletromiográficos do músculo masseter, subdividido em três regiões: superior, média e inferior, empregando-se o eletromiógrafo K6-I/EMG Eight Channel Surface Electromyograph (Myo-tronics Co., Seatle, WA, EUA), em 17 condições clínicas, e à análise cefalométrica através do programa Radiocef (RadioMemory, Floresta, BH, Brasil), de 15 medidas angulares e lineares. Os dados obtidos foram submetidos ao teste de correlação de Spearman, por meio do programa Statistica, release 4.3D (StatSoft, Inc., 1993, EUA). Correlações estatisticamente significantes foram encontradas entre as condições clínicas de repouso, propulsão livre da mandíbula, mastigação molar, oclusão cêntrica forçada, desvio lateral, deglutição de água, mastigação incisiva, fechamento contra-resistência e deglutição de saliva; e, entre as medidas cefalométricas, ângulo SNA, ângulo incisivo superior.NA, distância incisivo superior-NA, ângulo ANB, ângulo IMPA, distância Pog-NB, ângulo SN.Gn(Y), ângulo incisivo inferior.NB, ângulo interincisivo, distância incisivo inferior-NB, ângulo SN.GoGn, ângulo SN.Plano Oclusal, ângulo SNB e ângulo SND. As regiões superior, média e inferior do músculo masseter participaram em 32, 18 e 50% dos resultados estatisticamente significantes, respectivamente. Os resultados corroboram com hipóteses sobre a influência da musculatura no estabelecimento da maloclusão dental, e a relação entre a função dos músculos do sistema estomatognático e o desenvolvimento craniofacial precisa ser compreendida para se poder predizer o desenvolvimento craniofacial.
Embryologically, the bone tissue develops after muscle tissue. The temporomandibular and facial muscles are well defined when the cranial and facial ossifications occur, with bone structures developing inside of a muscle and fascia envelope. When active contractions begin in a muscle, it exerts an uninterrupted effect over bones to which belongs its origin and insertion. The bones tissues are one of the most plastic tissues, and interact readily to any tension and pressure developed by muscles. It\'s axiomatic that since previous to childbirth, muscles exert a role in bone structure development, and keep directing the skeletal growth with the effect of its functions. Eight patients (4? and 4?), between…

▼ Abstract: The malocclusion is an alteration of dental position and the shape of the arches that affects the musculoskeletal structures of the masticatory system of individuals affected by this condition. The objective of this study was analysis the morphofunctional alterations of mandible and two masticatory muscles. Forty eight male rats Novergicus Wistar divided into three groups of 16 animals, group 1: submitted to bilateral increased occlusal vertical dimension, group 2, submitted to posterior displacement of the mandible and group 3: control. The morphometric analyze of bone density of the alveolar process, ramus and base of mandible and the fibres modifications by histochemistry (NADH-tr) of the
masseter and temporal muscles, were effected by the ImageJ software. The densitometric analysis presented bone loss only in the base of the mandible in group 1 (0,454 ± 0,020) and increase in the bone content of mandible in group 2 (1,06E+06 ± 2,53+05) and other regions. The histochemical results showed the fast glycolytic fibers (FG) (1,06E+06 ± 2,53+05), area larger than fast glycolytic-oxidative fibers (FOG) (6,86E+05 ± 1,50E+05), while the slow oxidative (SO) (5,50E+05 ± 1,40E+05) was lower than the others. Among all fibers analyzed, the group 2 (8,89E+05 ± 2,56E+05) showed largest area than groups 1 (6,89E+05 ± 1,18E+05) and control (7,20E+05 ± 1,69E+05). The fibers of temporal
muscle (8,54E+05 ± 2,11E+05) presented largest area than the
masseter muscle (6,78E+05 ± 1,51E+05). There was predominance of FG fibers (22 ± 4) in relation the FOG (13 ± 3) and SO fibers (15 ± 4), to other in all groups and muscles studied. The temporal
muscle presented numerically more SO (15 ± 3,9) than FOG (12 ± 3), and
masseter muscle showed equal numbers of these fibers. The occlusal alterations provoked morphological changes in bone tissue of mandible and masticatory muscles.
