▼ Abstract: The objective of the present study was to evaluate the electromyographic (EMG) and stabilographic characteristics of individuals with and without temporomandibular disorder (TMD), during the mandibular rest position (MRP), the isometric contraction during maximal intercuspal position (MIP), and the isotonic contraction during no habitual chewing cycle (CC). In the evaluation of the EMG characteristics the following variable had been considered: normalized root mean square (nRMS) and symmetry of the temporalis, masseter and sternocleidomastoid (SCM) muscles. The evaluated stabilographic variables had been: sway index, maximum medial-lateral distance, maximum anteriorposterior distance and symmetry medial-lateral. This study evaluated 40 female volunteers: 20 with signals and symptoms of TMD and 20 asymptomatic individuals, constituting the control group. The variables were analyzed through repeated measures Anova and in case of significant effect multiple comparisons had been applied, using test t. The level of significance was p< 0.05. The results of this study had indicated that individuals with TMD present more pain in the cervical region (p<0.05), showing that the alterations of the mandibular motor system are related with alterations in the cervical system. The individuals with TMD had also presented greater asymmetry in the activity of the temporalis (p<0.001), masseter (p<0.0001) and SCM (p<0.0001) muscles and greater asymmetry in the medial-lateral distribution of weight (p<0.01) in relation to the control group. In the group with TMD was observed a significant reduction in the sway index (p<0.05) and maximum medial-lateral distance (p<0.05). Cervical pain in TMD group can have influenced in the reduction of the cervical movement to stabilize the head with an increase of the postural stability. The asymmetric activation of jaw and neck muscles is interpreted as a compensatory strategy to achieve stability for mandibular and cervical system during masticatory function Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Bérzin, Fausto, 1940- (advisor), Universidade Estadual de Campinas.

▼ Abstract: Surface electromyography (SEMG) has been consistently used by clinicians and researchers to assess muscular function. SEMG is considered an important instrument in the evaluation of muscular conditions in Temporomandibular Disorder (TMD) patients. However, it does not seem to be able to determine the presence of dysfunction because it is limited in terms of reliability, validity, sensibility and specificity. The aim of this study was to compare the SEMG of the temporalis anterior and masseter muscles in subjects classified by the Research Criteria Diagnosis for Temporomandibular Disorders (RDC/TMD) Axis I, and to find a measure that could better distinguish between TMD and non-TMD subjects. Once such a measure was found, the objective was to verify SEMG validity to diagnose TMD. Sixty-one female volunteers aged between 18 and 36 (23,3 ± 8,2) participated in this experiment. The volunteers were divided into two groups, namely TMD and control. The TMD group comprised 36 myogenic TMD patients and the control group consisted of 25 non-TMD subjects. The EMG records were obtained using the Myosystem BR-1 equipment with 12 channels, 12-bit resolution, and gain of 50 times. Differential surface electrodes (pure silver, gain 100) were used. The software Myosystem BR-1 3.0 version was employed to visualize and process the SEMG signal, with a frequency sample rate of 2000 Hz and digital band-pass filter of 10-500 Hz. The signals were then analyzed according to measures of Root Mean Square (RMS), Integral of Envelope Linear and Median Frequency. Maximal biting and bilateral chewing were assessed. The results were observed in relation to mean, standard deviation, coefficient of variation and angular coefficient of the linear regression, which were obtained from three epochs in each signal during the recorded period. Analysis of Variance (ANOVA) was used to assess the difference between groups, and Discriminant Analysis to test the diagnostic validity of SEMG. The mean of envelope linear values during dynamic contractions of the temporal muscle was different between groups (p<0,03), and the angular coefficient of the linear regression to RMS values was different during isometric (p<0,04) and isotonic (p<0,05) contractions in the same muscle. The sensibility values ranged from 80,6% to 84,3%, the specificity values ranged from 66,6% to 76% and predictive positive values ranged from 72,2% to75%%. Based on the findings, the SEMG of temporal anterior and masseter muscles is able to differentiate TMD and non-TMD subjects when the mean of envelope linear values during dynamic contractions is observed, and when the angular coefficient of linear regression for RMS values in static and dynamic contractions is examined. Nevertheless, the validity of SEMG as a diagnostic instrument for the TMD condition could not be corroborated in this study Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Bérzin, Fausto, 1940- (advisor), Universidade Estadual de Campinas.

▼ Abstract: This study investigated the characteristics of professional training, clinical practice and the biopsychosocial profile of dentists and physicians who treat orofacial pain. Based on a stratified design, 150 volunteers were selected at random, where 87 were from dentistry and 63 from medicine, coming from various regions of the country. The criteria for inclusion in the sample were: being an active member of SBED, SOBRAD, SBCe or ABFCOC; possessing the title of specialist in DTM/DOF by the Conselho Federal de Odontologia (Brazil¿s National Council on Dentistry) or possessing clinical experience in the area of orofacial pain. The instruments utilized were: 1) Research Form, elaborated by the investigator; 2) Questionnaire for Evaluation of Quality of Life (WHOQOL-BREF) and 3) Inventory of Stress Symptoms in Adults of LIPP (ISSL). The data were entered in a computer program especially developed for this research in Visual Basic, version 6.0, DOF/Data, and were submitted to statistical analyses using the SAS system which carried out a chi-squared test and Student t-test, at the 5% level of significance. The results indicate that the two groups of volunteers show indicators of deficiencies in academic training, being excessively technical, to practice in the area of pain. An analysis of clinical practice reveals that the majority of the volunteers recognize the need to improve their theoretical-technical understanding of the area of pain, admit difficulties in prescribing medications and in managing the behavior of the patient with chronic orofacial pain. Despite the feeling of professional achievement, unfavorable work conditions are apparent, such as excessive workload, being physically and mentally overworked and the need for several jobs. Despite a positive self-evaluation about health conditions and quality of life of the volunteers, a high prevalence was found for overweight, chronic pain ¿ especially lower back and neck pain, use of alcoholic beverages and medications to sleep, difficulty with memory, depression, ansiety, feeling constantly tired and irritable. This study points to the need to humanize the professional training of oral surgeons and physicians, not only with respect to relationships with the patient with pain, but also in helping with the psychosocial problems of these professionals. Emphasize here also for such healthcare professionals is the importance of improving one¿s lifestyle and taking better care of one¿s own physical and psychological health Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Siqueira, Jose Tadeu Tesseroli de (advisor), Universidade Estadual de Campinas.

▼ Abstract: Temporomandibular dysfunction (TMD) affects muscles and bones and is frequently associated with the presence of para-functional habits. Frequent signs and symptoms include limited mandibular movements, noise, masticatory and speaking difficulty, headaches, facial and cervical pain, and muscle pain in temporomandibular articulation (TMA). Pain is a common experience, and although it is not always present, the understanding of its physiological mechanisms has grown. The aim of clinical research is to gain knowledge and develop new technologies, including the elaboration of models for evaluation and diagnosis. In the evaluation of muscle function, surface electromyography (EMG) is considered a useful and sensitive tool. Twenty-one volunteers participated in the present study, whose ages ranged from 18 to 30 years. They were divided into 3 groups, the Control (with no dysfunction and with no pain), the TMD (with dysfunction, but no pain) and the PAIN (with dysfunction and with pain), in a manner that followed the sequential steps of the diagnostic protocol. TMD and pain were confirmed using the Research Diagnostic Criteria (RDC) and Fonseca questionnaires, dental examination and anamnesis. Bilateral EMG of the masseter muscles and the anterior portion of the temporal muscles was performed according to the protocol of the EMG Laboratory of FOP-UNICAMP. The signal was captured in three situations and at three times: isometric and isotonic contractions and regular chewing. This way, it was possible to demonstrate the complete absence of joint noise in the control group but its presence in the TMD (33.33% and PAIN (66.66%) groups during protrusion. It was also noted that for all the volunteers there were differences in the answers given at the beginning compared to the end of the RDC, suggesting a certain influence of some questions. During isometry in the control group, there was a functional inversion among the muscles on the right side. In the TMD group, functional inversion was seen also on the right side, along with masseter hyperfunction and a decrease in muscle electrical activity. The PAIN group showed functional inversion, points of muscle failure and a converging profile, indicating muscle fatigue. In isotony, the control group showed uniform masticatory cycles, a wide contraction period and normality period. However, the TMD group showed intensified electrical activity between contractions, while in the PAIN group electrical activity was constant among the muscles, besides the functional inversion among the muscles studied. For the PAIN group, there was notable electrical activity between the contractions and functional inversions. The results of median frequency (means) and RMS (means) in isometry, isotony and regular chewing for the muscles studied were evaluated by statistical analyses. The results do not demonstrate statistically significant differences among the three groups, thereby suggesting that the frequency of motor unit recruitment is similar and that there is no increasing or decreasing… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Bérzin, Fausto, 1940- (advisor), Universidade Estadual de Campinas.
