Introduction: The objective of this study was to compare pre-treatment and post-treatment cone-beam computed tomography images of patients to quantitatively evaluate the effect of orthodontically retracting maxillary incisors on the height and labiolingual thickness of labial and palatal alveolar bone and incisor apical
root resorption. Methods: Maxillary central incisor apical
root resorption, labial and palatal alveolar bone height, and labiolingual thickness were assessed on pre-treatment and post-treatment cone-beam computed tomography scans of 59 subjects (mean age, 13.00 years) with premolar extractions and 63 subjects (mean age, 13.40 years) who were treated with non-extraction therapy. Results: The mean incisor apical
root resorption in the extraction group was 1.47± 0.70 mm, compared to 0.70± 0.81 mm in the non-extraction group (P< 0.001). The extraction group also experienced greater palatal bone height loss (0.84± 1.08 mm) than the non-extraction group (0.22± 0.39 mm) (P< 0.001). Increased
root resorption was correlated with Class II malocclusion, increased OJ and OB, greater number of extracted premolars, long treatment duration, proximity of incisor roots to palatal cortex, and apical extrusion. Increased palatal alveolar bone height loss was correlated with greater number of extracted premolars, long duration of treatment, proximity of incisor roots to palatal cortex, and thin alveolar bone. Conclusion: Clinicians should exert caution when excessive incisor movement is planned in patients with thin alveolar bone.

▼ The aims of the present study were to evaluate the
root structure changes in untreated and buccal orthodontic tooth movement groups, with or without adjunctive flap surgery or corticotomy in an animal model, using Micro-CT. The null hypothesis was that there are no differences in the
root structure following orthodontic tooth movement, flap surgery, corticotomy or combinations of orthodontic tooth movement and surgery compared with a control group, in both experimental and contralateral sides. Thirty six male Sprague-Dawley rats were randomly divided into six groups (three control and three experimental): 1. Nil intervention 2. Flap surgery 3. Corticotomy procedure only 4. Tooth movement only 5. Flap surgery and tooth movement 6. Corticotomy with tooth movement The right maxillary first molar was chosen as the experimental tooth. In the tooth movement groups, a customised appliance was constructed which delivered a constant buccal force of 0.1N to the upper right first molar, over the 7 days of the experiment. In the surgery groups, a full thickness flap was raised on the buccal aspect using elevators and, in the corticotomy groups, cortical bone was perforated using a round slow speed bur. Following the corticotomy procedure, the raised flap was repositioned using a tissue glue. All animals were sacrificed seven days after appliance insertion. This was followed by dissection of the maxilla, resin embedding and Micro-CT scanning.
Micro-CT slices were assessed and the area of interest outlined. This consisted of the five roots of the maxillary right and left molar teeth from cemento-enamel junction to the apex of the tooth. Reconstructed images showed morphological
root structure changes which were further quantified by volumetric analysis. The results from reconstructed images showed changes in all three experimental groups; however, the greatest change was in the
root structure in the “Tooth movement with flap” and “Tooth movement with corticotomy” groups. The three control groups showed minimal to nil macroscopic change, in both experimental and non-experimental sides. Volumetric analysis reflected changes witnessed in reconstructed images, with a statistically significant reduction in volume of
root structure in the “Tooth movement with flap” and “Tooth movement with corticotomy” groups, as compared with the other four groups. When assessing the contralateral side in these groups, similar changes in morphology and volumetric analysis were found.
In conclusion, when assessing reconstructed images of corticotomy-assisted initial tooth movement in a rat model, morphological changes in
root structure were evident. These changes were reflected as decreased
root volume when comparing orthodontic tooth movement alone with orthodontic tooth movement with corticotomy and flap procedures. These changes were observed in both experimental and non-experimental sides. The results suggest that, although surgical intervention in conjunction with tooth movement may reduce mineral bone density and bone fraction in these…

▼ Hypothesis: We hypothesize that that concentrations of dentin matrix protein 1 (DMP-1) and dentin phosphophoryn (DPP) will be correlated with the amount of
root resorption observed in panoramic radiographs taken before and during orthodontic treatment. Objective:
Root resorption (RR) is a common complication of orthodontic treatment. Historically, only radiographic means have been available to detect RR in orthodontic patients. The goals of this study are to compare salivary DMP-1 and DPP levels at various time points during orthodontic treatment to baseline levels and to determine if an association exists between salivary DMP-1 and DPP levels and observed RR. Methods: Patients starting comprehensive orthodontic treatment were recruited to provide saliva samples before beginning treatment and roughly every 2 months until a panoramic radiograph was obtained. Saliva samples were collected, vortexed, and centrifuged with protease inhibitor. The samples were then analyzed using enzyme‐linked immunosorbent assay (ELISA) to detect DPP and DMP1. The incisor crowns and roots were measured on the pre-treatment and progress panoramic radiographs to calculate the amount of RR observed. The amount of
root resorption observed was compared to the DMP-1 and DPP levels. Results: N= 50 subjects participated in the study. DMP-1 concentration was higher at 2, 4, 6 and 8 months and DPP absorbance was higher at 2, 6 and 8 months after initiating orthodontic treatment compared to baseline (p<0.05). Maximum DMP-1 concentration was positively correlated to average incisor RR (p<0.05), but no correlation existed between average incisor RR and maximum DPP absorbance (p>0.05). Maximum DMP-1 concentration was higher in the group that experienced at least 10% RR on any tooth than the group that did not (p<0.05), while there was no significant difference in DPP absorbance between the two groups (p>0.05). Conclusions: These results show that DMP-1 and DPP are higher at most time points during orthodontic treatment compared to baseline. An association was found between OIIRR and DMP-1 concentration, but not DPP absorbance. Funding: NIH grant DE 11657 and the Brodie Endowment Fund IRB/ACC protocol: 2012-0767

▼ When camouflaging Class II malocclusions, there are
often changes to both the maxillary and mandibular incisor
angulations that can lead to artificial elongation and/or
foreshortening of the dental image. OIEARR is a common result of
orthodontic treatment and given the inherent limitations of 2D
radiography, it would be beneficial to better understand how
changes of tooth angulation can alter the perceived root lengths.
With this knowledge, clinicians may be better equipped at
recognizing cases of true root resorption as opposed to cases where
the appearance of root resorption on the radiograph is due to an
imaging foreshortening. This information can help clinicians
identify teeth that need further imaging (periapical) to
confirm/assess severity of root resorption and will also allow
clinicians to make modifications to their treatment in an attempt
to minimize the progression of root resorption. Research Question
1. Critically evaluate incisor OIEARR in patients undergoing
non-surgical treatment of Class II Division I malocclusion by
systematic review of the published data. a. Current evidence
suggests comprehensive orthodontic treatment to correct Class II
malocclusion results in increased prevalence of OIEARR, however
given the fact that there was no RCT and only limited prospective
data included in this SR, the findings should be considered with
caution. i. Prevalence ranged between 65.6%-98.1% ii. OIEARR -Per
patient – 65.6%-98.1% iii. OIEARR - Per tooth – 72.9%-94.2% iv.
Majority of teeth experienced mild-moderate resorption with severe
resorption being reported to be between 6.25-17.2% v. No Sex
difference was reported vi. No evidence that either the Mx CI or LI
more susceptible to RR vii. Weak to moderate positive correlation
between Tx duration and RR viii. Weak to moderate positive
correlation between AP apical displacement and RR 2. What is the
prevalence of OIEARR over the course of treatment in a selected
sample of patients treated with either the X-bow for Forsus? a.
Prevalence per tooth 65.3% b. Prevalence per patient 98.6% 3. What
is the severity of OIEARR over the course of treatment in a
selected sample of patients treated with either X-bow for Forsus?
a. Per tooth – None (34.7%); Mild (45.2%); Moderate (9.3%); Severe
(11%) b. Per patient – None (1.4%), Mild (32.9%); Moderate (30%);
Severe (35.7%) 4. Are the incisor length measurements determined
from panoramic radiographs accurate and reliable when maxillary and
mandibular incisor angulations are modified in a custom made
typodont? a. Under experimental conditions, Md incisors appear to
respond as expected when compared to theoretical model (assumption
– teeth within focal trough) i. 10 degrees – 1.4% shorter ii. 20
degrees – 6.3% shorter iii. 30 degrees – 13.4% shorter iv. 40
degrees – 23.7% shorter v. 50 degrees – 34.6% shorter b. Mx
Incisors are more difficult to say. At some angulations yes (80,
90), at others (50,60, 70, 100, 110) the answer isn’t clear c.
Severe Resorption in clinical study was found in 11% of treated
incisors and of the 25…

▼ The purpose of the study was to compare the incidence
and severity of External Apical
Root Resorption (EARR) in patients
treated with different orthodontic appliances. The definition of
EARR can be that of blunting or shortening of the
root apex, a
condition often associated with orthodontic treatment. In previous
studies it have been found that the teeth most susceptible to
root
resorption are the maxillary and mandibular incisors, with the
maxillary lateral incisors have the greatest incidence and degree
of
resorption. A number of studies have evaluated the role of
variables such as age, sex, malocclusion, dental
root anatomy,
appliance type, type of orthodontic force, and treatment time in
the development of external apical
root resorption. Few studies
have dealt with the effects of different orthodontic bracketing
systems on EARR. Standard edgewise, straight-wire, and Begg
appliances, as well as the newer self-ligating bracket systems,
have begun to be investigated.; The introduction and popularity of
Invisalign in treating more and more complex orthodontic
malocclusions provoked the investigation of its effect on external
apical
root resorption. Only a few clinical studies have been
published with regards to Invisalign and very few studies have been
completed that analyzed the effects of the Invisalign aligners. A
further aim was to analyze the degree of EARR in different tooth
groups in patients presenting with
root resorption. The sample
consisted of 90 female patients aged 10 – 58 years at the beginning
of orthodontic treatment. A conventional edgewise appliance (MBT
prescription, 0.22-inch slot) and the Invisalign appliance were
used.
Root resorption in all anterior tooth groups, (canines,
lateral incisors, central incisors), of both maxilla and the
mandible were evaluated from pre- and post-treatment panoramic
radiographs. Of the tooth groups, maxillary lateral incisors showed
EARR most frequently, followed by the maxillary central incisors
and then the mandibular incisors.
Root resorption was significantly
correlated with the conventional edgewise appliance treatment and
not with the Invisalign treatment. The most severe
resorption was
seen in the maxillary lateral incisors. It is concluded that with
the fixed conventional edgewise appliance, the risk of EARR is
higher than when malocclusions are treated with the Invisalign
appliance. In this study there was not any recordable external
apical
root resorption present when the malocclusions were treated
with the Invisalign clear removable aligners.

Root resorption has two main types: physiological and pathological. The
resorption is physiological only in case of primary dentition just before the teeth are replaced. Pathological
resorption can be internal and external. There are many different theories which exist about the etiology of
resorption. Normally they are divided into local and systemic causes. Two main pathomechanisms are responsible for the process
root resorption: inflammatory and by replacement. External
root resorption develops due to a pathological stimulus, which creates a disturbance in the balance between the activity of cementoblasts and that of the osteoclasts.

▼ Aims: To investigate whether patient- or tooth-related factors like jaw location or intra- and interarch obstacles influence the amount of orthodontic tooth movement and orthodontically induced root resorption, and to evaluate if the concept of slow and fast movers is valid in humans. Furthermore, to evaluate the validity of different radiographic methods for detecting root resorption.
Patients and methods: A standardized experimental split mouth model for orthodontic tooth movement was used in 30 subjects, 59 premolars were moved buccally during 8 weeks with the application of 1 N force and 58 contralateral premolars served as controls. The amount of tooth movement was evaluated with digitized superimposed plaster models. At the end of the experimental period the teeth were extracted, scanned in a micro-CT scanner, and a volumetric evaluation of resorption craters at the cervical part of the root was performed. The possible influencing factors studied were age, location (maxilla/mandible), and presence or absence of intra- or interarch obstacles. Standardized periapical radiographs, taken before and after the experiment, were evaluated for apical root resorption and compared with the micro-CT scanned images. In a different sample of 275 teeth in 22 patients near the end of an orthodontic treatment with fixed appliances, apical root resorption was evaluated in panoramic radiographs (OPT) and compared to the corresponding cone-beam CT images (CBCT).
Results: Younger subjects (<16 years) showed greater amount of tooth displacement compared with older subjects (≥16 years): 2.68mm vs. 1.84mm (P <0.01). When an intra-arch or interarch obstacle was present, the amount of tooth movement was significantly less (1.86mm vs. 2.67mm) (P<0.05). Teeth moved to a greater amount in the maxilla compared to the mandible but the displacement varied substantially between individuals (0.6–5.8mm) and was highly correlated within the same individual (R=0.88, P<0.001). Higher amount of cervical root resorption was detected in orthodontically moved teeth (0.00055mm3) compared to controls (0.00003mm3; P<0.001). A moderate correlation was found between root resorption in the two experimental teeth within the same individual (R=0.42, P=0.02). Root resorption was greater in the mandible than the maxilla. The amount of root resorption was correlated with the amount of tooth movement (R=0.31, P=0.01). The comparison of the apical radiographs and the micro-CT scanner showed less accuracy in the conventional radiograph. Panoramic radiographs underestimated apical root resorption as compared to the more precise CBCT 3D images.
Conclusions: A wide range of tooth displacement revealed slow and fast movers. Intra- or interarch obstacles decreased the amount of tooth movement. Younger patients showed greater tooth movement velocity than older ones. Application of 1N over 8 weeks may provoke notable root resorption, which varied widely between and within subjects. A part of this variation was attributed to the location and the amount of tooth movement.…

▼ Assessment of crown/
root ratio is important in many clinical situations. In orthodontics, practitioners commonly use panoramic radiographs to assess external orthodontically induced apical
root resorption. Unfortunately, using panoramic radiographs for this purpose may not lead to reliable and accurate conclusions due to multiple drawbacks of the technique.
This research focuses on assessment of crown/
root ratio measurements of teeth from dried skulls and the possible effect of patient positioning in the panoramic machine on the measurements.
We also evaluated the accuracy of the crown/
root ratio of incisors and canines measured on panoramic radiographs at ideal head position compared to the same measurements performed on cone beam computer tomographs (CBCT).
The sample consisted of 24 dried skulls. Panoramic and CBCT radiographs were taken. Panoramic radiographs were taken under 7 different head positions. Baseline head position (0 ) was established when the horizontal laser orientation line passed through Porion-Orbitale. The skull was then tilted +5o, +10o, +15o upward and -5o, -10, -15o downward. Crown/
root ratios of all teeth were measured on panoramic radiographs. Only incisors and canines were measured on the CBCT.
We found upward/downward head tilt to significantly affect crown/
root ratio measurements of all groups of teeth except lower incisors. Maxillary teeth were more sensitive to upward head tilt, while downward head tilt was more forgiving, affecting only molars. There were no differences in crown/
root ratio measurements of lower incisors and canines between panoramic radiographs at ideal head position and CBCT scans. However, there were differences in crown/
root ratio measurements of upper incisors and canines between panoramic radiographs at ideal head position and CBCT scans.

▼ Introduction:
Root resorption following orthodontic
treatment is common and often does not have deleterious effects on
the longevity of the teeth. Previous methods of imaging
root
resorption include panoramic radiographs and periapical
radiographs. Cone Beam Computed Tomography (CBCT) is now available
to assess
root resorption in 3 dimensions. Research Objective: To
understand the 3 dimensional pattern of
root resorption on
maxillary incisors that underwent orthodontic treatment.
Additionally, is there a correlation between direction of tooth
movement and pattern of
root resorption? Methods: 25 patients (100
teeth) were involved in this study. Cone Beam Computed Tomography
(CBCT) scans which had been taken pre and post treatment were
analyzed to assess
root resorption pattern and direction of
movement. Results:
Root resorption can occur not only at the apex
in a vertical manner, but also at the mesial, distal, palatal and
facial surfaces of the
root. When the teeth moved in the apical
direction (31 instances)
root resorption on the isolated apical
surface of the
root was found 94% of the time (29 instances). When
the teeth moved in the palatal direction (65 instances)
root
resorption on the isolated palatal surface of the
root was found
20% of the time (13 instances). Conclusion:
Root resorption was
observed on the surface of
root movement, however it was also
observed on surfaces not related to
root movement. The clinician
may consider the direction of
root movement in diagnosis and
treatment planning of orthodontic treatment, and in the assessment
of risk factors for
root resorption.

▼ Trabalho apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Medicina Dentária.
Cada vez mais os pacientes que necessitam de tratamento ortodôntico fazem terapias
concomitantes. De forma a relacionar o tratamento ortodôntico com os bisfosfonatos
(BFs), foi feita uma revisão bibliográfica, baseada em informação obtida por pesquisa
manual e via online, no “Google”, “MEDLINE/PubMed”, “Science Direct ” e “B-On”.
As palavras-chave foram: “orthodontic tooth movement”, “bisphosphonates”,
“orthodontics”, “osteonecrosis”, “bone resorption”, “rats”, “root resorption”, “rapid
expansion”, “retention”. Só nos últimos 40 anos, os BFs têm sido implementados no
tratamento de desordens do metabolismo do cálcio, por inibirem a reabsorção óssea.
Estes podem ser administrados em crianças e adultos, por via oral e intra-venosa. Como
o movimento ortodôntico dentário (MOD) consiste na aposição e reabsorção ósseas
localizadas, a sua amplitude é afectada (inibida) por este medicamento. Este efeito pode
ser desejável ou indesejável. Assim, a terapia com BFs pode prevenir a reabsorção
radicular, associada ao MOD; preservar os resultados dos procedimentos que requerem
neoformação óssea (ex. expansão maxilar ou distracção mandibular); promover retenção
mais segura, após expansão; sistemicamente diminuem as fracturas ósseas e têm
propriedades anti-angiogénicas e antineoplásicas. Contudo, podem provocar
cicatrização óssea comprometida e osteonecrose. São necessários mais estudos
prospectivos e ensaios clínicos randomizados, de forma a avaliar e potenciar os efeitos
benéficos da terapia com BFs no tratamento ortodôntico. Increasingly, patients who require orthodontic treatment make concomitant therapies. In
order to relate the orthodontic treatment with bisphosphonates (BFS), a literature review
was made, based on information obtained through manual and online search, using
"Google", "MEDLINE / PubMed", “Science Direct ” and "B-On". The key words were:
"orthodontic tooth movement", "bisphosphonates," "orthodontics", "osteonecrosis,"
"bone resorption", "rats", "root resorption", "rapid expansion," "retention". Only in the
last 40 years, the BFS has been implemented in the treatment of disorders of calcium
metabolism, by inhibiting bone resorption. They can be administrated to children and
adults, oral and intravenous. As the orthodontic tooth movement (OTM) consists in
apposition and bone resorption, its amplitude is affected (inhibited) by this drug. This
effect may be desirable or undesirable. Thus the BFS therapy can prevent root
resorption associated with the OTM, preserve the results of procedures that require new
bone formation (eg maxillary expansion and jaw distraction), promoting safer retention
after expansion; systemically reduce bone fractures and have anti-angiogenic and
antineoplastic properties. However, they can cause impaired bone healing and
osteonecrosis. Further prospective randomized studies and clinical trials are needed, to
assess and…

▼ O diagnóstico diferencial do ameloblastoma é de grande interesse entre clínicos e pesquisadores, uma vez que sabe-se que o diagnóstico presuntivo inadequado pode acarretar em sérios problemas ao paciente. A busca por estabelecer critérios radiográficos para essa neoplasia é um desafio ainda atual. Dentro desse contexto, as reabsorções dentárias têm sido relatadas como um achado frequente e característico nas análises de ameloblastomas, mas ainda traz consigo certa insegurança quando a especificidade deste sinal. Esse trabalho tem o objetivo de avaliar a presença das reabsorções dentárias no ameloblastoma e seu padrão de aparecimento pela análise retrospectiva e revisão sistemática. Para o estudo retrospectivo foram selecionados 40 pacientes, com diagnóstico de ameloblastoma e 14 estudos foram incluídos na revisão sistemática. Com exceção da faixa etária, todos os resultados encontrados na casuística são consonantes com os da revisão sistemática.
Não foi observado predileção por gênero e a localização mais comum foi a mandíbula. A reabsorção dentária foi observada em 95% dos 40 casos analisados e em 64,8% dos casos obtidos pela revisão sistemática. O padrão imaginológico mais frequente foi o em plano, seguido pelo irregular, e superficial, respectivamente. As lesões em sua grande maioria eram grandes no momento do diagnóstico, sendo que essas duas últimas variáveis foram avaliadas somente no estudo retrospectivo. Foi possível concluir que as reabsorções dentárias são uma característica frequente nos ameloblastomas e devem ser consideradas como um sinal importante e diferencial no momento de realização do diagnóstico presuntivo dessa neoplasia
The differential diagnosis of ameloblastoma is of great interest among clinicians and researchers, since it is known that inadequate presumptive diagnosis can lead to several problems in the patient. The search for establishing radiographic criteria for this neoplasm is still a
challenge in science. Within this context, dental resorptions have been reported as a frequent finding in ameloblastoma analyzes, but still carry some controversy. This study aims to evaluate the presence of dental resorptions and their pattern of appearance through retrospective analysis and a systematic review. For the retrospective study, 40 patients with a diagnosis of ameloblastoma were selected and 14 studies were included in the systematic review. Exception for age group, all the results found in the series agreed with those found in the systematic review. No predilection by gender was observed, the most common location was the mandible. Dental resorption was observed in 95% of the 40 cases analyzed and in 64,8% of the cases obtained by the systematic review. The most frequent pattern was flat-cutting, followed by irregular and superficial, respectively. The majority of lesions were large at the time of diagnosis, and the latter two variables were evaluated only in the
retrospective study. It was possible to conclude that dental resorptions are a frequent feature in ameloblastomas and…

▼ A favourable tooth crown-to-root ratio is required for
supporting the tooth, but also for withstanding occlusal forces.
This ratio is adversely affected when the tooth root is shortened.
Orthodontically induced tooth root resorption is an unwanted side
effect of orthodontic tooth movement. In severe cases, resorption
of the tooth root apex progressing coronally results in tooth root
shortening, which may lead to tooth loss. This type of root
resorption is reported to occur in 40% of adults receiving
orthodontic tooth movement where these patients had root shortening
of 2.5 mm or more in at least one of their teeth. Orthodontically
induced root resorption may even occur within 35 days of
orthodontic treatment and even with only light forces. Currently,
no simple and reliable technique is available to repair the damage
caused by orthodontically induced root resorption, therefore, a new
method is needed that can regenerate the lost tooth root tissue.
Low intensity pulsed ultrasound has been reported to enhance
osteoblastic differentiation, increase proliferation, and induce
osteogenic differentiation in cells. It has also been shown to
enhance the repair of resorbed tooth roots in Beagle dogs. Another
treatment technique involved in periodontal repair (including
alveolar bone and cementum) is stem cell therapy. Stem cells, and
cells that have stem cell properties, that possibly could be used
in periodontal repair, including periodontal ligament (PDL) stem
cells, bone marrow stem cells, and gingival cells/fibroblasts, have
shown promise in repairing periodontal defects, however, gingival
cells/fibroblasts are more easily accessible and involve less donor
site morbidity. Previous to the current study, there is no study
that had evaluated the effect of LIPUS and osteogenic induced
gingival fibroblasts (OIGFs) on the repair of orthodontically
induced root resorption. Therefore, the aim of the present study
was to evaluate the effect of these treatment modalities (OIGFs and
LIPUS) using histomorphometric and micro-computed tomography
analyses. The results of this study using histomorphometric
analysis revealed that ultrasound and the combination of ultrasound
and OIGFs were effective at increasing cementum thickness near the
apex of the root (p 0.05). Using micro-computed tomographic
analysis, it was shown that ultrasound, OIGFs , and the combination
of the two treatments had an effect on reducing root resorption
lacunae depth and volume (p 0.05). In conclusion, using low
intensity pulsed ultrasound and OIGFs, alone or in combination with
each other, may have a promising effect on repairing damage caused
by orthodontically induced root resorption. Additional studies that
examine these treatments’ effects on the inflammatory aspect of
root resorption, employing a carefully separated multipotent
gingival cells, and track/ label these cells to determine their
incorporation into the tissues are required to fully understand
their effect in this repair process.

▼ INTRODUCTION: One of the most common side effects of orthodontic treatment is
root resorption, a reactive process in which the length of the dental roots become progressively shortened during treatment. A phenomenon of developmentally-short dental roots, known as Short
Root Anomaly (SRA) has been observed in many orthodontic patients of Hispanic descent in the UIC Orthodontic clinic. Studies have reported a predisposition to
root resorption in Caucasian patients with developmentally short roots. While the presentation of SRA in Hispanic patients has been described previously, it is not known if this population is predisposed to increased orthodontic
root resorption.
METHODS: Maxillary and mandibular central and lateral incisors and second premolars of 40 Hispanic patients with SRA (19 male, 21 female) and 40 Caucasian patients (19 male, 21 female), matched for age and extractions, were evaluated for
root resorption following comprehensive orthodontic treatment. Panoramic radiographs were measured digitally and relative
root length was calculated before and after orthodontic treatment.
RESULTS: The results from paired sample t-tests demonstrate that, while there was statistically significant
root resorption in the control group following comprehensive orthodontic treatment, orthodontic
root resorption was not significant in the Hispanic group (P> 0.05). When genders were separated, Hispanic females did experience a mild degree of
root resorption in the upper incisors. Caucasian females experienced greater
root resorption than Caucasian males.
CONCLUSION: These data indicate that Hispanic SRA patients may be safely treated with orthodontics and could be at no more risk of
root resorption than Caucasian patients with normal initial
root length. Although more studies are needed, these findings can be used in making educated treatment decisions regarding this specialized population of orthodontic patients. To the authors’ knowledge, this is the first study to evaluate the response of Hispanic patients with SRA to orthodontic treatment.

▼ Objective: To investigate and develop an appropriate
measurement protocol possessing adequate precision in both intra-
and inter-rater reliability for in vivo maxillary first molar
volume measurements using cone beam computed tomography (CBCT)
images. To assess in vivo through the use of CBCT imaging whether
the type of maxillary expansion appliance [BAME versus
tooth-anchored maxillary expander (TAME)] impacts the amount of
external root resorption in maxillary first molars as compared to a
no treatment control group. Methods: 62 adolescents requiring
maxillary expansion were randomly allocated to groups: TAME, BAME,
and control. CBCT images were acquired at baseline and
approximately 12-months. Segmentation procedures were investigated
and developed to quantify maxillary first molar ERR. Dental volumes
were measured on the CBCT images at both time points to assess
maxillary first molar dental volume changes. Results: Excellent
intra- and inter-rater agreement for segmentation. Automated
thresholding with manual refinements on a 2D slice-by-slice basis,
yielded the highest intra- and inter-rater reliability statistics.
There lacked statistically significant evidence (p>0.05) of
differences in external root resorption (both percentage and
absolute volume) between TAME, BAME, and control groups.
Conclusion: Whole tooth CBCT segmentation employing grayscale
thresholding with 2D slice-by-slice manual refinements possesses
excellent intra- and inter-rater reliability. There is no
statistically significant evidence supporting increased ERR with
TAME or BAME versus control.

▼ Ultrasound has been widely utilized in diagnostic and
therapeutic clinical practices. Further development of the
application of ultrasound in the clinical practices requires
comprehensive understanding of the physics of ultrasound
propagation in biological tissues. In this research, computer
simulation was used as a means for investigating the physics of
ultrasound propagation in two particular diagnostic and therapeutic
applications of ultrasound. In the field of diagnostic ultrasound,
quantitative ultrasound (QUS) for bone assessment was considered.
Accurate diagnosis and monitoring osteoporosis based on measuring
velocity and attenuation of ultrasonic waves transmitted into
cancellous bone are the eventual aims of QUS. In this regards, the
interaction between the micro-structure of cancellous bone and
ultrasonic waves should be fully understood. Although many
researches have been dedicated towards this goal, the physics of
ultrasound propagation in cancellous bone has not yet been fully
revealed. One of the approaches towards investigating the physics
of the propagation is using computer simulation. QUS has been
conventionally simulated using the finite difference time-domain
(FDTD) method. However, large discrepancy (up to 75%) has been
reported in the results of simulated QUS experiments when the FDTD
method was employed. Some part of the discrepancy is logically
believed to originate from the FDTD scheme for resolving the
micro-structure of cancellous bone, and implicit formulations of
the material discontinuity at the solid-fluid (bone-fluid)
interface in the heterogeneous medium of cancellous bone. To
mitigate the effect of these discrepancy sources, the standard
Galerkin finite element method (FEM) in time domain was used as an
alternative to the FDTD method. To demonstrate the capability of
the FEM for simulating ultrasound propagation in cancellous bone,
three-dimensional finite element models of six water-saturated
cancellous bone samples were created and analyzed. The obtained
relations between the simulated ultrasonic parameters (velocity and
attenuation of the ultrasound) and the bone density of the samples
showed that different degree of osteoporosis presented by the
sample could be clearly distinguished by the simulations. Moreover,
comparing the results with other experimental and simulation
studies indicated that the finite element simulations were in
agreement with them; therefore, the FEM was demonstrated to be
capable of simulating ultrasound propagation in water-saturated
cancellous bone. To further investigate the accuracy of the method,
finite element simulations and QUS experiments of ultrasound
propagation in cancellous bone-mimicking phantoms, i.e. aluminum
foams, were performed. The simulations and the experimental results
had an average relative error of 10% when the simulated and
experimental ultrasonic attenuation values were compared with each
other. Assumed to be mainly caused by disregarding energy-absorbing
mechanisms in the simulations, the observed discrepancy (10% on
average)…

▼ The aim of this thesis was to investigate the
biological effects of LIPUS on orthodontically induced inflammatory
resorption (OIIRR) in in vivo and in vitro models. The in vitro
samples were obtained from healthy human premolars and cultured for
5-days or 24-hours with application of LIPUS at different doses.
The in vivo, we tested 10 beagle dogs where orthodontic movement
was carried out for four weeks with a continuous force of 1 N/side;
using a split mouth model. After 4-weeks, mandibles were resected
into blocks involving the fourth premolar and its periodontal
tissue. The 4th premolars were evaluated using micro-CT,
histologically and immunohistochemically. In both models, LIPUS was
generated with repetition rate of 1 KHz. Each pulse has a square
envelop with duration of 200 microseconds and a carrier frequency
of 1.5 MHz and 30mW/cm2 intensity. Daily application of LIPUS on
TSOC for 5-days did not have any effect on the predentin thickness
layer, and had an adverse effect on the odontoblast cell count. A
one-time application of LIPUS in a 5-day culture of TSOC increased
the predentin thickness in all groups. Also it increased the
odontoblast cell count in the 5, 10 and 15 minutes application
groups. LIPUS application for 10 minutes upregulated the expression
of collagen-I and DMP-1 in the short term (24 h), where 5-minutes
application upregulated the expression of collagen-I only. LIPUS
did not affect the rate of orthodontic tooth movement and had a
trend of increasing it with increased population of the osteoclasts
attached to the alveolar bone in the PDL. LIPUS significantly
reduced the number of OIIRR initiation areas by 71%, reduced its
total volume by 68%, and reduced its volume relative to the
affected root total volume by 70%. LIPUS induced the formation of
precemntum layer, thicker cementum and reparative cellular
cementum.

▼ Different pathology associated with impacted wisdom teeth in the oral cavity showed that it is prevalent and may lead to varied dental complications. This study adopted a descriptive cross-sectional retrospective analytical design in order to examine hard tissue features associated with the presence of impacted third molars in a random sample of 2998 digital panoramic radiographs (DPRs) of patients' records in Tygerberg Oral Health Centre, Faculty of Dentistry, University of Western Cape. The specific objectives of the study were to categorize the type of impactions in the DPRs of patients and to determine the prevalence of distal cervical caries (DCC) in second molars, any radiolucent (RL) /radiopaque (RO) lesions or external
root resorption (ERR) complications associated with impacted wisdom teeth. Results of the pantomographs and clinical records of patients indicated that the most prevalent type of impaction (TOI) is Mesioangular (MA) Impaction (65%) followed by Horizontal (H) Impaction (17%), Vertical (V) Impaction (15%), Transverse (TVS) Impaction (2 %) and Distoangular (DA) Impaction (1.2 %), respectively. The least prevalent type was Inverted (INV) Impaction with a frequency count of 0.5%. The results further indicated varied dental complications resulting from impaction, ranging from ERR with a frequency of 3% of which 66.70% was associated with MA type of impaction, followed by H with a frequency of 26.7%. The association of Gender and RL/ RO lesions was significant (p-value=0.04) while association between DCC and types of impaction was also significant (p-value =0.0017). The study concluded that the high prevalence of MA among all populations and genders over the years may be related to the anatomical normal inclination of the third molars to the mesial surface. The low prevalence of DA observed in the study sample on the other hand might be attributable to gender and demographic factors. Lastly, this study has only one radiopaque lesion and the high prevalence of RL lesions in males and in the older age group suggests that these complications take a while to develop. Future research is needed to raise more awareness and encourage patients to seek treatment of symptomatic and asymptomatic third molars before complications arise.

▼ The present study was designed to investigate the relationships between clinicopathological findings and the resorptive conditions of root apices of teeth with periodontitis. The samples included 21 root apices with large periapical radiolucent lesions. The preoperative computed tomography (CT) and intraoperative findings were correlated with the presence, extension, and the progression pattern of periapical resorption using a scanning electron microscope. The subjects' age, gender, chief complaint, type of tooth, percussion test results, size of periapical lesion using CT, and intraoperative findings were recorded. All apicoectomies were performed under an operative microscope for endodontic microsurgery. A significant large size was observed in cystic lesions compared with granulomatous lesions. The cementum surface at the periphery of the lesion was covered with globular structures (2–3 μm in diameter). Cementum resorption started as small defect formations at the surface. As the
defect formation progressed, a lamellar structure appeared at the resorption area, and the size of globular structures became smaller than that of globules at the surface. Further resorption produced typical lacuna formation, which was particularly observed in fracture cases. The most morphologically severe destructive pattern of dentin resorption was observed in large cystic lesions. This study is the first report to elucidate the relationships between three clinical types of undesirable periapical lesions: (1) undertreatment, (2) periapical fracture, (3) macro-level resorption, and the microstructure of external root resorption including from small defects at the cementum surface to a significant destructive pattern inside the dentin.

▼ Introduction:
Root resorption is an undesired but frequent side effect of orthodontic treatment. Several studies have already aimed to evaluate the performance of CBCT on this topic. However, none have addressed the peculiarities of the most common daily orthodontic scenario. The aim of the study was to evaluate the influence of CBCT scans on the diagnosis of artificial external
root resorption in the apical third of anterior teeth. Materials and methods: One hundred extracted human anterior teeth were randomly assigned to 2 uneven groups (51 as the control and 49 as the experimental group). A limited area of the apical third of the
root of the teeth of the experimental group was selected and a buffer solution was used to induce tooth subsurface demineralization. Before CBCT image acquisition, each tooth was coated with an approximately 0.3 mm thick layer of utility wax to simulate the radiographic appearance of the periodontal space and placed into an empty mandibular anterior socket of a partially edentulous dry human mandible. The mandible was placed into a polystyrene box filled with water prior to the CBCT examination to simulate soft-tissue attenuation and scattering. The CBCT images were obtained on an i-CAT unit (i-CAT Next Generation, Imaging Sciences International, Hatfield, PA) according to three protocols: (I) half scan (180°), 0.40 mm voxel size; (II) full scan (360°), 0.40 mm voxel size; and (III) full scan (360°), 0.125 mm voxel size. The 300 resultant CBCT DICOM volumes were imported into InVivo software (InVivo5, Anatomage, San Jose, CA) for evaluation by three blinded, previously calibrated observers using a five-point confidence rating scale. Cohen’s kappa was used to calculate observers’ agreement. The diagnostic values of sensitivity (Sn), specificity (Sp) and accuracy (Ac) were performed by pooling observer responses for every image modality. Receiver operating characteristic (ROC) were built and the areas under the curve (AUC) were calculated. The Sn, Sp and Ac values were compared by Cochran’s Q test. The AUC values were compared by Mann-Whitney U test. Results: The observers’ agreement ranged from 0.63 to 0.71, which was interpreted as a substantial agreement. Protocol III (0.125 mm voxel size) displayed the highest Sn (81.63 %), Ac (80.67%) and AUC (0.807). There were statistically significant differences between protocol III and the other two protocols (p < 0.001). The specificity of protocol I (84.97 %) was greater than that of protocols II (69.93 %) and III (79.74 %); however statistically significant difference was only found between protocols I and II (p = 0.005). Conclusion: Although there was no difference in accuracy between the degrees of rotation (half and full scan) within the same voxel size (0.4 mm), there was a considerable difference between those and the smallest voxel size (0.125 mm). In fact, it may be suggested that a more dedicated, high resolution scan should be acquired when one intends to investigate the early stage of external
root…

▼ Purpose: The purpose of this study was to compare the
effects of ibuprofen, a conventional NSAID, and celebrex, a COX-2
specific inhibitor, on tooth movement and
root resorption. Methods:
49 female wistar rats were placed into 5 groups: (1) control (no
dosage), (2) high dose celebrex (80mg/kg body weight), (3) high
dose ibuprofen (50 mg/kg), (4) low dose celebrex (40 mg/kg), and
(5) low dose ibuprofen (25 mg/kg). Rats were anesthetized by IP
injection of Phenobarbital (0.1 mg/gm body weight), and a force of
80 grams was applied to the maxillary left first molars using a
nickel titanium closed-coil spring. Tissue samples analyzed by
light microscopy, and areas of
resorption were quantified. Results:
Ibuprofen and celebrex reduced
resorption compared to control. High
dose celebrex caused a reduction of tooth movement. Conclusions:
There is minimal advantage in using selective COX-2 inhibitors to
limit
resorption; however, treatment time may be
lengthened.

▼ O presente trabalho investigou microscopicamente o efeito da equistatina sobre o processo reabsortivo de dentes incisivos superiores de ratos, extraídos e reimplantados. Foram utilizados 42 animais, divididos em grupos com e sem equistatina. Os tempos extra-alveolares dos dentes foram de 30 e 60 minutos e os períodos experimentais pós-cirúrgicos foram 15, 60 e 90 dias. Os espécimes obtidos foram processados e corados em H.E. para observar os processos biológicos presentes. Os eventos microscópicos foram avaliados por dois examinadores, de modo quantitativo histomorfométrico e descritivo, de acordo com o tipo de infiltrado e intensidade da reação inflamatória; com o tipo, extensão e localização de reabsorção dentária; e presença de anquilose alveolodentária. O nível de concordância entre examinadores, determinado pelo índice Kappa, revelou-se quase perfeito para todas as variáveis avaliadas. A comparação entre os grupos testes e controle para as
variáveis apresentadas foi feita por meio do teste Mann-Whitney e mostrou não haver diferença estatística entre a administração de equistatina e tempo extra-alveolar em relação à intensidade inflamatória nas diferentes porções radiculares. Quanto ao tipo de reabsorção estabelecida, notou-se que a presença de reabsorção inflamatória foi significativamente maior (p<0,05) no grupo controle nos tempos de 30 e 60 minutos no período pós-cirúrgico de 15 dias. A anquilose alveolodentária também esteve significativamente mais presente no grupo tratado com equistatina com 30 minutos extra-alveolar e 15 dias de período experimental. Houve, ainda, mais anquilose alveolodentária no grupo controle de 60 minutos extra-alveolar, com o período experimental de 60 dias. No período experimental de 90 dias todos os espécimes avaliados apresentaram processos reabsortivos inflamatórios e ausência de anquilose alveolodentária. O teste Kruskall-Wallis avaliou as diferenças significantes entre grupos,
em relação à intensidade inflamatória por terço radicular, tipo de reabsorção e anquilose alveolodentária. As comparações individuais foram realizadas com teste Dunn e mostrou diferenças significantes entre grupos teste em relação ao período experimental. As variáveis testadas também foram avaliadas pelo teste de correlação de Spearman, que demonstrou haver correlações positivas substanciais ou muito fortes entre as variáveis: intensidade inflamatória no 1/3 cervical e no 1/3 médio, intensidade inflamatória no 1/3 cervical e no 1/3 apical e intensidade inflamatória no 1/3 médio e no 1/3 apical. Destacou-se ainda a correlação negativa substancial entre tipo de reabsorção e a intensidade inflamatória do 1/3 médio radicular. O uso de implantes de ELVAX com equistatina demonstrou possuir um potencial terapêutico na prevenção de processos reabsortivos inflamatórios no modelo experimental de reimplante de incisivos superiores murinos.

O reimplante dentário é o tratamento de escolha para a avulsão e o seu sucesso tem relação direta com a vitalidade do ligamento periodontal e controle da contaminação. O controle da inflamação durante o processo de reparo do periodonto após o reimplante tem grande importância porque a sua persistência pode favorecer a reabsorção dentária. Tem-se recomendado a antibioticoterapia sistêmica, porém faltam estudos que demonstrem o seu real papel nesse processo. Portanto, o objetivo do trabalho foi avaliar o efeito da antibioticoterapia sistêmica com amoxicilina e tetraciclina após reimplante dentário imediato em ratos. Noventa ratos (Rattus norvegicus albinus, variedade Wistar) tiveram os incisivos
extraídos e armazenados em 20 ml de solução de soro fisiológico por 5 minutos. Em seguida, os dentes foram reimplantados e os animais divididos em 3 grupos de acordo com o antibiótico administrado por via intragástrica (Técnica de Gavagem): Grupo I - soro fisiológico, Grupo II - Amoxicilina e Grupo III - Tetraciclina. A eutanásia ocorreu aos 7, 15 e 30 dias após o reimplante. Os dados obtidos foram submetidos na análise histomorfométrica foram submetidos a análise estatística. Independente do período analisado o tecido conjuntivo subjacente à reinserção epitelial e o ligamento periodontal mostraram diferença estatística quanto ao infiltrado inflamatório aguda que se apresentava mais intenso no grupo controle seguido pelo grupo da Tetraciclina. Esses resultados permitem concluir que a antibioticoterapia sistêmica, no reimplante dentário imediato, favorece o processo de reparo da polpa e do ligamento periodontal e que a Amoxicilina foi mais efetiva que a Tetraciclina
Tooth
replantation is the choice treatment for avulsion and its success has a direct relationship with the vitality of the periodontal ligament and contamination control. The control of inflammation during periodontal repair after replantation is quite important, because it's persistence may promote resorption. It has been recommended the systemic antibiotic therapy, although there are just a little studies that demonstrate its real effect in the process. Therefore, the aim of the study was to evaluate the effect of systemic antibiotic therapy with amoxicillin and tetracycline after immediate tooth replantation in rats. The incisors of 90 rats (Rattus norvegicus albinus variety Wistar) were extracted and stored in 20 ml of saline solution for 5 minutes. Then, the teeth were replanted and the animals were divided into 3 groups according to the antibiotic administered by gavage: Group I – saline, Group II - amoxicillin and Group III - tetracycline. The rats were euthanized at 7, 15 and 30
days after reimplantation. Regardless of the analyzed period, the connective tissue underlying the epithelial reattachment…

O reimplante dentário é o tratamento de escolha para a avulsão e o seu sucesso tem uma relação direta com a vitalidade do ligamento periodontal e controle da contaminação. O controle da inflamação durante o processo de reparo do periodonto após o reimplante tem grande importância porque a sua persistência pode favorecer a reabsorção dentária. Tem-se recomendado a antibioticoterapia sistêmica, porém seu valor é questionável. Sendo assim, o objetivo do trabalho foi avaliar o efeito da antibioticoterapia sistêmica com Amoxicilina e Tetraciclina após reimplante dentário tardio em ratos. Noventa ratos tiveram os incisivos superiores direito extraídos e mantidos 60 minutos em meio ambiente. Após
esse período a polpa e o ligamento periodontal foram removidos e os dentes imersos em solução de fluoreto de sódio fosfato acidulado a 2%. Em seguida o canal radicular foi preenchido com pasta de hidróxido de cálcio e um plug apical de MTA e os dentes reimplantados. Os animais foram divididos em 3 Grupos de acordo com o antibiótico utilizado. No Grupo I - controle, Grupo II - Amoxicilina e Grupo III - Tetraciclina. A eutanásia ocorreu aos 7, 15 e 30 dias após o reimplante. Independente do período analisado o infiltrado inflamatório agudo foi menor no grupo da Amoxicilina. Quanto à reabsorção radicular esta apresentou com menor extensão e profundidade também no grupo da Amoxicilina o que permite concluir que a antibioticoterapia sistêmica tem uma influência positiva no processo de reparo do reimplante dentário tardio e a Amoxicilina mostrou-se mais efetiva no controle do processo inflamatório
The tooth replantation is the treatment of choice for avulsion and its success has a
direct relationship with the vitality of the periodontal ligament and contamination control. The control of inflammation during periodontal repair after replantation is of great importance because its persistence may promote resorption. Systemic antibiotic therapy has been recommended in such cases, but its value is questionable. Therefore, the objective of this study was to evaluate the effect of systemic antibiotic therapy with Amoxicillin and Tetracycline after delayed tooth replantation in rats. Ninety rats were extracted incisors and held 60 minutes in the environment. After this time the pulp and periodontal ligament were removed, and the teeth were immersed in a solution of sodium fluoride and 2% acidulated phosphate. Then the root canal was filled with calcium hydroxide paste and an MTA apical plug, and the teeth were replanted. The animals were divided into three groups according to the types of the antibiotics. In Group I - control, Group II - Amoxicillin and Group III -
Tetracycline. Evaluations were made at 7, 15 and 30 days after replantation. Regardless of the analyzed period the acute…
