Abstract
INTRODUCTION The present study aimed to assess the influence of facial pattern in smile attractiveness on different levels of gingival exposure evaluated by dental specialists and laypersons. METHODS Frontal photographs of 2 white Brazilian women, one with a long face and the other with a balanced face, were acquired and subsequently modified to simulate gingival exposure from 0 to 6 mm. Four groups of evaluators of both sexes (mean age 34 y), including laypersons (n = 24) and dental specialists (n = 72; 24 orthodontists, 24 periodontists, and 24 maxillofacial surgeons), used a Likert-type scale to evaluate the attractiveness of the smiles of these subjects with different levels of gingival exposure. Kruskal-Wallis and Friedman tests were used to compare the perceptions of the dental specialists and laypersons. Spearman rank correlation coefficient was used to associate the age of the examiners with their rating outcomes. Statistical significance was set at P < 0.05. RESULTS Statistically significant differences were observed for the following levels of exposure for the long-faced subject: 0 mm, 4 mm, 5 mm, and 6 mm. Laypersons were less critical than dental specialists. In the balanced-face subject, statistically significant differences were observed between laypersons and dental specialists for gingival exposure levels of 4 mm, 5 mm, and 6 mm. Laypersons perceived gingival exposure to a lesser extent for the balanced-face subject than for the long-face subject. The balanced face was better rated than the long face by dental specialists and laypersons for all levels of gingival exposure. CONCLUSIONS Facial patterns influenced the smile attractiveness evaluation. The facial characteristics of a balanced facial pattern attenuated the perception of gingival exposure.

Abstract
OBJECTIVES To evaluate the influence of text messages on cooperation of Class II patients with the use of intermaxillary elastics. MATERIALS AND METHODS The sample consisted of 42 orthodontic patients (20 males and 22 females) aged between 14 and 34 years. They were randomly divided into one of the following two groups: a control group with 21 patients who did not receive messages and an experimental group with 21 patients who received motivational and reminder text messages. Messages were sent twice a week for a period of 3 months. The patients were instructed to wear the elastics all day, removing them only during meals and replacing them daily. All patients were instructed regarding the importance of cooperation. Measurements were performed with a digital caliper on plaster models at the beginning of elastics wear (T1) and 3 months later (T2). For intragroup and intergroup comparisons between T1 and T2, paired and unpaired t-tests, respectively, were used with a significance level of 5%. RESULTS Statistically significant differences were observed in the intra- and intergroup comparisons between T1 and T2. Both groups showed a decrease in the sagittal distance between upper and lower arches from T1 to T2, demonstrating the effective use of elastics. However, the experimental group showed a Class II correction that was 3.7 times greater than the control group ( P = .001). CONCLUSIONS Text messages had a positive influence on the cooperation of patients regarding the use of intermaxillary elastics in the orthodontic treatment of Class II malocclusion.

Abstract
Objective: The objective of this study was to evaluate the facial attractiveness in 30 black individuals, according to the Subjective Facial Analysis criteria. Methods: Frontal and profile view photographs of 30 black individuals were evaluated for facial attractiveness and classified as esthetically unpleasant, acceptable, or pleasant by 50 evaluators: the 30 individuals from the sample, 10 orthodontists, and 10 laymen. Besides assessing the facial attractiveness, the evaluators had to identify the structures responsible for the classification as unpleasant and pleasant. Intraexaminer agreement was assessed by using Spearman's correlation, correlation within each category using Kendall concordance coefficient, and correlation between the 3 categories using chi-square test and proportions. Results: Most of the frontal (53. 5%) and profile view (54. 9%) photographs were classified as esthetically acceptable. The structures most identified as esthetically unpleasant were the mouth, lips, and face, in the frontal view; and nose and chin in the profile view. The structures most identified as esthetically pleasant were harmony, face, and mouth, in the frontal view; and harmony and nose in the profile view. The ratings by the examiners in the sample and laymen groups showed statistically significant correlation in both views. The orthodontists agreed with the laymen on the evaluation of the frontal view and disagreed on profile view, especially regarding whether the images were esthetically unpleasant or acceptable. Conclusions: Based on these results, the evaluation of facial attractiveness according to the Subjective Facial Analysis criteria proved to be applicable and to have a subjective influence; therefore, it is suggested that the patient's opinion regarding the facial esthetics should be considered in orthodontic treatmentplanning.

Abstract
Introduction: Cone-Beam Computed Tomography (CBCT) is essential for tridimensional planning of
orthognathic surgery, as it allows visualization and evaluation of bone structures
and mineralized tissues. Tomographic slices allow evaluation of tooth inclination
and individualization of movement performed during preoperative decompensation.
The aim of this paper was to assess maxillary and mandibular incisors inclination
pre and post orthodontic decompensation in skeletal Class III malocclusion. Methods: The study was conducted on six individuals with skeletal Class III malocclusion,
surgically treated, who had Cone-Beam Computed Tomographic scans obtained before
and after orthodontic decompensation. On multiplanar reconstruction view,
tomographic slices (axial, coronal and sagittal) were obtained on the long axis of
each incisor. The sagittal slice was used for measurement taking, whereas the
references used to assess tooth inclination were the long axis of maxillary teeth
in relation to the palatal plane and the long axis of mandibular teeth in relation
to the mandibular plane. Results: There was significant variation in the inclination of incisors before and after
orthodontic decompensation. This change was of greater magnitude in the mandibular
arch, evidencing that natural compensation is more effective in this arch, thereby
requiring more intensive decompensation. Conclusion: When routinely performed, the protocols of decompensation treatment in surgical
individuals often result in intensive movements, which should be reevaluated,
since the extent of movement predisposes to reduction in bone attachment levels
and root length.

Abstract
Objective To verify the effects of rapid maxillary expansion performed after secondary alveolar bone graft in one patient. Setting Department of Orthodontics of the Hospital for Rehabilitation of Craniofacial Anomalies, University of Sao Paulo. Patient(s) The patient had bilateral cleft lip and palate, had already had a bone graft, and showed a relapsing maxillary constriction in need of correction. Intervention A fixed dental-mucous-bone-supported expander corrected the maxillary constriction. Main Outcome Measure(s) Measurements were obtained from dental casts, including transverse dimensions (intercanine distance [IC], interfirst premolar distance [IP], and interfirst molar distance [IM]) and measurements of the grafted area (interfirst premolar/central incisors [IPI] and interfirst premolar/canine [IPC]) to observe the changes. Clinical and radiographic analyses were done through direct view. Results The occlusal radiograph of the maxilla after expansion showed opening of the intermaxillary suture in the premaxillary area, which was clinically confirmed by the diastema between the maxillary central incisors. No radiographic alteration was observed in the grafted area. The transverse measurements of the dental casts (IC, IP, and IM) showed a significant increase. The measurements of the teeth adjacent to the grafted area, IPI and IPC, increased. Conclusions The orthopedic effect of rapid maxillary expansion after bone graft was verified. Nevertheless, additional studies are necessary to define any side effects in patients submitted to bone graft.

Abstract
In Brazilian cities and states governed efficiently with wealth ethically administered, carious and periodontal diseases have prevalence rates similar to those found in socially developed European countries. This shift in reality, noticed over the last 15 years, reflects on changes in the etiological factors related to patients' major expectations and needs - especially young and orthodontic patients - which turn out to be a result of dental trauma, malocclusion, facial aspect, dental agenesis and iatrogenesis. Under such conditions, patients begin to appreciate the value of tooth position, color and shape, their smile and function: details become relevant. Carious and periodontal diseases remain an issue, not only from a preventive prospect, but also from a curative one. Nevertheless, it should be noted that changes and development are inevitable, and we should be prepared to contribute to the wellbeing of people, particularly regarding their novel needs and expectations.

Abstract
Aim: This study aimed at assessing the prevalence and severity of short face pattern in ethnically different individuals. Material and Methods: The sample comprised 4,409 Brazilians (2,192 females and 2,217 males), with a mean age of 13 years, enrolled in secondary schools in the municipality of Bauru. The sample inclusion criteria involved subjects with vertically impaired facial relationship based on excessive lip compression, when standing at natural head position, with the lips at rest. Once short face syndrome had been identified, the individuals were classified into three severity subtypes: mild, moderate, and severe. The sample was then stratified by ethnic background as White (Caucasoid), Black (African descent), Brown (mixed Caucasian–African descent), Yellow (Asian descent), and Brazilian Indian (Native Brazilian descent), using the Brazilian Institute of Geography and Statistics classification. The chi-square test at the 5% significance level was used to compare frequency ratios of individuals with vertically impaired facial relationships and across different ethnicities, according to severity. Results: The prevalence of short face pattern was 3.15%, as 1.11%, 1.99%, and 0.02% considered mild, moderate and severe subtypes, respectively. The severe subtype was rare (0.02%) and found only in one White individual. The White group had the highest relative frequency (45.53%) of the moderate subtype, followed by Brown individuals (43.40%). In the mild subtype, Yellow (68.08%) and White (62.21%) individuals showed similar and higher relative frequency values. Conclusion: The prevalence of short face pattern was 3.15%, and White individuals had the highest prevalence.

Abstract
OBJECTIVE: The present study assessed the maxillary dental arch changes produced by
surgically assisted rapid maxillary expansion (SARME). METHODS: Dental casts from 18 patients (mean age of 23.3 years) were obtained at treatment
onset (T1), three months after SARME (T2) and 6 months after
expansion (T3). The casts were scanned in a 3D scanner (D-250, 3Shape,
Copenhagen, Denmark). Maxillary dental arch width, dental crown tipping and height
were measured and assessed by ANOVA and Tukey's test. RESULTS: Increased transversal widths from T1 and T2 and the
maintenance of these values from T2 and T3 were observed.
Buccal teeth tipping also showed statistically significant differences, with an
increase in all teeth from T1 to T2 and a decrease from
T2 to T3. No statistically significant difference was
found for dental crown height, except for left first and second molars, although
clinically irrelevant. CONCLUSION: SARME proved to be an effective and stable procedure, with minimum periodontal
hazards.

Abstract
OBJECTIVE The aim of the present study was to evaluate, comparatively, the periodontal response during orthodontic treatment performed with self-ligating and conventional brackets. METHODS Sixteen Caucasian individuals of both sexes, aged between 12 and 16 years old and in permanent dentition were selected. Eight individuals were treated with conventional brackets installed on the lower dental arch and self-ligating brackets on the upper arch. Another eight individuals received self-ligating brackets in the lower arch and conventional brackets in the upper arch. The subjects received material and instructions for oral hygiene. Visible plaque index (VPI), gingival bleeding index (GBI) and clinical attachment level (CAL) were evaluated just after installation of orthodontic appliances, and 30, 60 and 180 days later. Mann-Whitney test was used to compare differences between groups (self-ligating and conventional), two-way ANOVA followed by Tukey's test was used to assess CAL at each site of each tooth. Significance level was set at 5%. RESULTS No significant changes were found with regard to the assessed parameters (VPI, GBI and CAL) in either one of the systems. CONCLUSION No significant changes were found with regard to the periodontal response to orthodontic treatment for the variables assessed and between subjects receiving passive self-ligating and conventional brackets. All individuals had received oral hygiene instructions and had their periodontal conditions monitored.

Abstract
Consistently performed by most orthodontists, the orthopedic treatment involves rapid maxillary expansion (RME) combined with maxillary protraction (MP). When this treatment protocol is performed up to the intertransitional period of the mixed dentition (around 9 years of age), it allows a positive influence on the maxilla and zygomatic projection, even though there are also effects on the dentition. The ideal orthopedic treatment should influence the growth and spatial arrangement of bone bases (maxilla and mandible), so as to achieve balance and maintain it until growth completion. This goal may seem utopic, especially when the problem involves the mandible; and, assuming some genetic influence for such disorder, it is difficult to predict its future magnification during the growth period. Notwithstanding, despite the uncertain prognosis, the search for function and better facial esthetics, though temporary, should be considered This paper discusses this topic, based on the treatment progress of a youngpatient with Class III, with monitoring ofgrowth from the deciduous dentition up to adulthood, and treatment performed in two periods, using the RME and MPprotocol. Positive outcomes were achieved.

Abstract
INTRODUCTION: Prognosis is the main limitation of interceptive treatment of Class III
malocclusions. The interceptive procedures of rapid maxillary expansion (RME) and
face mask therapy performed in early mixed dentition are capable of achieving
immediate overcorrection and maintenance of facial and occlusal morphology for a
few years. Individuals presenting minimal acceptable faces at growth completion
are potential candidates for compensatory orthodontic treatment, while those with
facial involvement should be submitted to orthodontic decompensation for
orthognathic surgery. OBJECTIVES: To investigate cephalometric variables that might predict the outcomes of
orthopedic treatment with RME and face mask therapy (FM). METHODS: Cephalometric analysis of 26 Class III patients (mean age of 8 years and 4
months) was performed at treatment onset and after a mean period of 6 years and 10
months at pubertal growth completion, including a subjective facial analysis.
Patients was divided into two groups: success group (21 individuals) and failure
group (5 individuals). Discriminant analysis was applied to the cephalometric
values at treatment onset. Two predictor variables were found by stepwise
procedure. RESULTS: Orthopedic treatment of Class III malocclusion may have unfavorable prognosis at
growth completion whenever initial cephalometric analysis reveals increased lower
anterior facial height (LAFH) combined with reduced angle between the condylar
axis and the mandibular plane (CondAx.MP). CONCLUSION: The results of treatment with RME and face mask therapy at growth completion in
Class III patients could be predicted with a probability of 88.5%.

Abstract
The aim of this research was to evaluate age-related changes in the smile of Brazilian women. The sample consisted of 249 Brazilian women who had not undergone previous orthodontic treatment or facial surgery. They were divided into four groups, according to age: G1 (20-29), G2 (30-39), G3 (40-49) and G4 (50 or older). Standardized front view photographs were taken while smiling and at rest. Measurements were evaluated by ANOVA and post-hoc Tukey. The Chi-square test was applied for qualitative variables. Upper lip thickness at rest and exposure of upper incisors on smiling decreased with age. Most individuals (60.9%) exhibited a medium smile. High smiles were more often seen in G1 (45%) and less frequently in G4 (18.8%), whereas the opposite occurred with the low smile, i.e., G4 (21.9%) and G1 (6.7%). Variations among the groups were observed in the transverse exposure of the teeth on smiling. In G1 and G3, there was a balance between tooth exposures, so that the teeth were exposed as far as the premolars and/or molars. Most of the women (56.3%) in G2 exposed their teeth as far as the first molars on smiling, whereas most of those (40.6%) in G4 exposed their teeth only as far as the first premolars on smiling. As age increased, there was decreased exposure of the upper incisors, decreased upper lip thickness and lower exposure of teeth vertically and transversely.

Abstract
The aim of this clinical report is to describe the complex treatment of an adult Class III malocclusion patient who was disappointed with the outcome of a previous oral rehabilitation. Interdisciplinary treatment planning was performed with a primary indication for implant removal because of marginal bone loss and gingival recession, followed by orthodontic and surgical procedures to correct the esthetics and skeletal malocclusion. The comprehensive treatment approach included: (1) implant removal in the area of the central incisors; (2) combined orthodontic decompensation with mesial displacement and forced extrusion of the lateral incisors; (3) extraction of the lateral incisors and placement of new implants corresponding to the central incisors, which received provisional crowns; (4) orthognathic surgery for maxillary advancement to improve occlusal and facial relationships; and finally, (5) orthodontic refinement followed by definitive prosthetic rehabilitation of the maxillary central incisors and reshaping of the adjacent teeth. At the three-year follow-up, clinical and radiographic examinations showed successful replacement of the central incisors and improved skeletal and esthetic appearances. Moreover, a Class II molar relationship was obtained with an ideal overbite, overjet, and intercuspation. In conclusion, we report the successful esthetic anterior rehabilitation of a complex case in which interdisciplinary treatment planning improved facial harmony, provided gingival architecture with sufficient width and thickness, and improved smile esthetics, resulting in enhanced patient comfort and satisfaction. This clinical case report might be useful to improve facial esthetics and occlusion in patients with dentoalveolar and skeletal defects.

Abstract
Objective: This study aimed at assessing the relationship between facial morphological
patterns (I, II, III, Long Face and Short Face) as well as facial types
(brachyfacial, mesofacial and dolichofacial) and obstructive sleep apnea (OSA) in
patients attending a center specialized in sleep disorders. Methods: Frontal, lateral and smile photographs of 252 patients (157 men and 95 women),
randomly selected from a polysomnography clinic, with mean age of 40.62 years,
were evaluated. In order to obtain diagnosis of facial morphology, the sample was
sent to three professors of Orthodontics trained to classify patients' face
according to five patterns, as follows: 1) Pattern I; 2) Pattern II; 3) Pattern
III; 4) Long facial pattern; 5) Short facial pattern. Intraexaminer agreement was
assessed by means of Kappa index. The professors ranked patients' facial type
based on a facial index that considers the proportion between facial width and
height. Results: The multiple linear regression model evinced that, when compared to Pattern I,
Pattern II had the apnea and hypopnea index (AHI) worsened in 6.98 episodes.
However, when Pattern II was compared to Pattern III patients, the index for the
latter was 11.45 episodes lower. As for the facial type, brachyfacial patients had
a mean AHI of 22.34, while dolichofacial patients had a significantly statistical
lower index of 10.52. Conclusion: Patients' facial morphology influences OSA. Pattern II and brachyfacial patients
had greater AHI, while Pattern III patients showed a lower index.

Abstract
Introduction Orthodontics, just as any other science, has undergone advances in technology that
aim at improving treatment efficacy with a view to reducing treatment time,
providing patients with comfort, and achieving the expected, yet hardly attained
long-term stability. The current advances in orthodontic technology seem to
represent a period of transition between conventional brackets (with elastic
ligatures) and self-ligating brackets systems. Scientific evidence does not always
confirm the clear clinical advantages of the self-ligating system, particularly
with regard to reduced time required for alignment and leveling (a relatively
simple protocol), greater comfort for patients, and higher chances of performing
treatment without extractions - even though the number of extractions is more
closely related to patient's facial morphological pattern, regardless of the
technique of choice. Orthodontics has recently and brilliantly used bracket
individualization in compensatory treatment with a view to improving treatment
efficacy with lower biological costs and reduced treatment time. Objective This paper aims at presenting a well-defined protocol employed to produce a better
treatment performance during this period of technological transition. It explores
the advantages of each system, particularly with regards to reduced treatment time
and increased compensatory tooth movement in adult patients. It particularly
addresses compensable Class III malocclusions, comparing the system of
self-ligating brackets, with which greater expansive and protrusive tooth movement
(maxillary arch) is expected, with conventional brackets Capelozza Prescription
III, with which maintaining the original form of the arch (mandibular arch) with
as little changes as possible is key to yield the desired results.

Abstract
Replacing both missing maxillary anterior teeth is particularly challenging, especially in compromised sockets. This case report describes the management of an 18-year-old female patient, who suffered avulsion of both maxillary central incisors at 7 years of age. This multidisciplinary implant technique, called Immediate Dentoalveolar Restoration (IDR), included extraction of the injured teeth and a single procedure for immediate implant placement and restoration of the compromised sockets after root fracture and periapical lesion development were detected during orthodontic treatment. Successful esthetic and functional outcomes and reestablishment of the alveolar process after bone reconstruction were observed during the 3-year follow-up period. The predictable esthetic outcomes and soft- and hard-tissue stability that can be achieved following IDR are demonstrated.

Abstract
Controlling the eruption and development of dentitions is fundamental for a good oral health. The early diagnosis and adequate treatment of occasional developmental disorders are essential to achieve occlusal, functional and esthetic harmony. Abnormality is the term used for classification of alterations and is the most common developmental anomaly in humans. Even though several factors causing tooth malformations have been identified, many are still partially understood, thus requiring a more thorough study. Anyway, the available knowledge provides bases to attempt the early diagnosis of tooth abnormalities, to allow the adoption of preventive and effective therapeutic approaches.

Abstract
PURPOSE To assess the facial esthetics of patients with complete bilateral cleft lip and palate, and to compare the judgment of raters related and unrelated to cleft care. MATERIALS AND METHODS The sample comprised 23 adult patients (7 women and 16 men) with a mean age of 26.1 years, rehabilitated at a single center. Standardized photographs of the right and left facial profile were taken of each patient and subjectively evaluated by 25 examiners: 5 orthodontists and 5 plastic surgeons with expertise in oral cleft rehabilitation, 5 orthodontists and 5 plastic surgeons without expertise in oral cleft rehabilitation, and 5 laypersons. The facial profiles were classified into 3 categories: esthetically unpleasant, esthetically acceptable, and esthetically pleasant. Intraexaminer and interexaminer agreements were evaluated with the Spearman correlation coefficient and Kendall coefficient of concordance. The differences between rater categories were analyzed using the Student-Newman-Keuls test (with P < .05 indicating a statistically significant difference). RESULTS Most of the sample was classified as esthetically acceptable. Orthodontists and plastic surgeons related to oral cleft rehabilitation gave the best scores to the facial profiles, followed by layperson examiners and by orthodontists and plastic surgeons unrelated to oral cleft rehabilitation. The middle third of the face, the nose, and the upper lip were frequently pointed out as contributors to the esthetic impairment. CONCLUSIONS The facial profile of rehabilitated adult patients with complete bilateral cleft lip and palate was considered esthetically acceptable because of morphologic limitations in the structures affected by the cleft. Laypersons and professionals unrelated to oral cleft rehabilitation seem to be more critical regarding facial esthetics than professionals involved with cleft rehabilitation.

Abstract
The contemporary orthodontics should highlight the periodical control of growth and dental development in order to intercept possible disorders in facial growth and tooth eruption. This may allow avoidance or simplification of corrective orthodontic treatment, making it faster and less aggressive. Tooth transposition, a genetically determined eruptive disturbance, presents a relatively low prevalence in the world population and primarily affects maxillary canines and premolars. This paper presents an option for interceptive treatment of bilateral transposition of maxillary canine and premolar diagnosed early in a young individual. Longitudinal follow-up of RME performed in adequate timing to redirect the eruption pathway of permanent maxillary canines is presented.

Abstract
OBJECTIVE The aim of this study was to assess the magnitude of occlusal changes in individuals with unilateral cleft lip and palate (CLP). The study was conducted on study cast models of 25 subjects, 14 men and 11 women aged from 7 to 20 years, without previous orthodontic treatment and with surgical repair carried out at São Marcos Hospital, Teresina, Piauí State, Brazil. METHODS The cast models were assessed by three orthodontists based on the occlusal scores established by Atack et al., whose scores range from 1 to 5, according to the magnitude of transverse and sagittal changes. RESULTS Intra and inter-observer reproducibility of occlusal scores was satisfactory and statistically significant according to the Spearman correlation test with significance level set at 5%. With regard to the distribution of occlusal scores, 30.67% of the subjects achieved scores 1 and 2, 22% score 3 and 47.53% achieved scores 4 and 5. CONCLUSIONS Four was the score most frequently assigned by the observers, disclosing a high degree of transverse and sagittal disorders in the occlusion of patients.

Abstract
OBJECTIVE The present study aimed at analyzing, with the use of dental casts, the transverse changes of the upper and lower dental arches, after non-extraction orthodontic treatment, with self-ligating brackets. METHODS The sample comprised 29 patients, all presenting Class I malocclusion with upper and lower crowding of at least 4 mm and treated only with a fixed appliance, without stripping, extraction or distalization. The dental casts were obtained before and after leveling with 0.019 x 0.025-in stainless steel archwires. CONCLUSIONS The results indicated that the majority of transverse changes occurred at the premolar areas, both the first and the second, as well as on the upper and lower dental arches. The intercanine distance increased 0.75 mm, on average, in the upper arch and 1.96 mm in the lower arch. The molars also demonstrated a tendency towards an increase in their transverse dimension, however, at a lower intensity comparing to premolars. All measurements presented statistically significant differences with the exception of the maxillary second molars.

Abstract
Objective: The long face pattern is a facial deformity with increased anterior total facial
height due to vertical excess of the lower facial third. Individuals with long
face may present different degrees of severity in vertical excess, as well as
malocclusions that are difficult to manage. The categorization of vertical excess
is useful to determine the treatment prognosis. This survey assessed the
distribution of ethnically different individuals with vertical excess according to
three levels of severity and determined the prevalence of long face pattern. Material and Methods: The survey was comprised of 5,020 individuals of Brazilian ethnicity (2,480
females and 2,540 males) enrolled in middle schools in Bauru-SP, Brazil. The
criterion for inclusion of individuals with vertically impaired facial
relationships was based on lip incompetence, evaluated under natural light, in
standing natural head position with the lips at rest. Once identified, the
individuals were classified into three subtypes according to the severity: mild,
moderate, and severe. Then the pooled sample was distributed according to ethnical
background as White (Caucasoid), Black (African descent), Brown (mixed descent),
Yellow (Asian descent) and Brazilian Indian (Brazilian native descent). The
Chi-square (χ2) test was used (p<0.05) to compare the frequency
ratios of individuals with vertically impaired facial relationships in the total
sample and among different ethnicities, according to the three levels of severity.
Results: The severe subtype was rare, except in Black individuals (7.32%), who also
presented the highest relative frequency (45.53%) of moderate subtype, followed by
Brown individuals (43.40%). In the mild subtype, Yellow (68.08%) and White
individuals (62.21%) showed similar and higher relative frequency values. Conclusions: Black individuals had greater prevalence of long face pattern, followed by Brown,
White and Yellow individuals. The prevalence of long face pattern was 14.06% in
which 13.39% and 0.68% belonged to moderate and severe subtypes, respectively.

Abstract
INTRODUCTION Vitamin D is responsible for the regulation of certain genes at the transcription level, via interaction with the vitamin D receptor, and influences host immune responses and aspects of bone development, growth, and homeostasis. Our aim was to investigate the association of TaqI vitamin D receptor gene polymorphism with external apical root resorption during orthodontic treatment. METHODS Our subjects were 377 patients with Class II Division 1 malocclusion, divided into 3 groups: (1) 160 with external apical root resorption ≤1.43 mm, (2) 179 with external apical root resorption >1.43 mm), and (3) 38 untreated subjects. External apical root resorption of the maxillary incisors was evaluated on periapical radiographs taken before and after 6 months of treatment. After DNA collection and purification, vitamin D receptor TaqI polymorphism analysis was performed by polymerase chain reaction-restriction fragment length polymorphism. Univariate and multivariate analyses were performed to verify the association of clinical and genetic variables with external apical root resorption (P <0.05). RESULTS There was a higher proportion of external apical root resorption in orthodontically treated patients compared with the untreated subjects. In patients orthodontically treated, age higher than 14 years old, initial size of the maxillary incisor root superior to 30 mm, and premolar extraction were associated with increased external apical root resorption. Genotypes containing the C allele were weakly associated with protection against external apical root resorption (CC + CT × TT [odds ratio, 0.29; 95% confidence interval, 0.07-1.23; P = 0.091]) when treated orthodontic patients were compared to untreated individuals. CONCLUSIONS Clinical factors and vitamin D receptor TaqI polymorphism were associated with external apical root resorption in orthodontic patients.

Abstract
INTRODUCTION: The search for orthodontic treatment by adult patients is increasing. This demand may be explained by many reasons, but the most important was the change in the concept of normality, allowing the selection of simpler and more conservative and consistent therapeutic objectives. This conceptual evolution, combined with the technological advances allowed an improvement in orthodontic management, making it more effective, fast and comfortable. The promotion of awareness of the society on the advantages of this treatment and the increase in esthetic demands, with an increasingly longer and active social, affective and professional life, creates a context in which the need for Orthodontics is absolutely established for the adult individuals. OBJECTIVE: The objective of this article is to report the nuances in diagnosis and orthodontic treatment of an adult patient, in a different perspective. Within this approach, the objective is to recover the shape, i.e. to establish occlusal conditions that would probably be present if the patient had been assisted at the proper time, namely during growth and tooth irruption.

Abstract
OBJECTIVE: The assessment and establishment of the facial growth pattern for patients with a cleft palate. MATERIAL: This cross-sectional retrospective study was based on front and profile photos of a sample of 71 patients at the HRAC-USP, 22 males and 49 females, Brazilians, young adults, with a mean age of 17 years 8 months, without previous orthodontic treatment and no associated syndromes. The method was the subjective facial diagnosis based on technical concepts, that is, the qualitative morphologic analysis of the face through clinical examination. Individuals were classified as Pattern I, II, III, Long Face or Short Face. RESULTS: The distribution found with the frontal morphologic analysis was: Pattern I (69%), II (6%), III (7%), Long (18%) and Short (0%). As for the profile morphologic analysis, the distribution was: Pattern I (35%), II (38%), III (10%), Long (17%) and Short (0%).The distribution observed in the frontal analysis was very positive, since individuals Pattern I prevailed. For the profile evaluation, the anterior-posterior dysplasias were essentially shown, significantly increasing their participation. Long Face Pattern maintained a balance in both ratings and Short Face Pattern was not found in the sample used, probably related to the low prevalence in the general population. CONCLUSION: The prevalence of different Facial Patterns for patients with cleft palate was similar to that found in individuals without cleft.

Abstract
INTRODUCTION: The opinion on the 'straight-wire' concept has been evolving since its origin, characterized by faithful followers or absolute skepticism. Currently, it seems reasonable to state that most professionals have a more realistic and critical viewpoint, with an attitude that reveals Orthodontics' maturity and greater knowledge on the technique. The most relevant criticisms refer to the impossibility of the both the Straight-Wire and the Standard systems to completely express the characteristics related to the brackets due to mechanical deficiencies, such as bracket/wire play. OBJECTIVES: A critical analysis of this relationship, which is unclear due to lack of studies, was the scope of this paper. METHODS: The compensatory treatment of two patients, using Capelozza's individualized brackets, works as the scenery for cephalometric evaluation of changes in incisor inclination produced by different dimensions of leveling archwires. RESULTS: The evaluation of these cases showed that, while the introduction of a 0.019 x 0.025-in stainless steel archwire in a 0.022 x 0.030-in slot did not produce significant changes in incisor inclination, the 0.021 x 0.025-in archwire was capable of changing it, mainly in mandibular incisors, and in the opposite direction to the compensation. CONCLUSION: Considering compensatory treatments, even when using an individualized prescription according to the malocclusion, the bracket/wire play seems to be a positive factor for malocclusion correction, without undesirable movements. Therefore, it seems reasonable to admit that, until a bracket system can have absolute individualization, the use of rectangular wires that still have a certain play with the bracket slot is advisable.

Abstract
INTRODUCTION In this study, we evaluated the effects of a low-level laser on bone regeneration in rapid maxillary expansion procedures. METHODS Twenty-seven children, aged 8 to 12 years, took part in the experiment, with a mean age of 10.2 years, divided into 2 groups: the laser group (n = 14), in which rapid maxillary expansion was performed in conjunction with laser use, and the no-laser group (n = 13), with rapid maxillary expansion only. The activation protocol of the expansion screw was 1 full turn on the first day and a half turn daily until achieving overcorrection. The laser type used was a laser diode (TWIN Laser; MMOptics, São Carlos, Brazil), according to the following protocol: 780 nm wavelength, 40 mW power, and 10 J/cm(2) density at 10 points located around the midpalatal suture. The application stages were 1 (days 1-5 of activation), 2 (at screw locking, on 3 consecutive days), 3, 4, and 5 (7, 14, and 21 days after stage 2). Occlusal radiographs of the maxilla were taken with the aid of an aluminum scale ruler as a densitometry reference at different times: T1 (initial), T2 (day of locking), T3 (3-5 days after T2), T4 (30 days after T3), and T5 (60 days after T4). The radiographs were digitized and submitted to imaging software (Image Tool; UTHSCSA, San Antonio, Tex) to measure the optic density of the previously selected areas. To perform the statistical test, analysis of covariance was used, with the time for the evaluated stage as the covariable. In all tests, a significance level of 5% (P <0.05) was adopted. RESULTS From the evaluation of bone density, the results showed that the laser improved the opening of the midpalatal suture and accelerated the bone regeneration process. CONCLUSIONS The low-level laser, associated with rapid maxillary expansion, provided efficient opening of the midpalatal suture and influenced the bone regeneration process of the suture, accelerating healing.

Abstract
Missing maxillary lateral incisors create an esthetic problem with specific orthodontic and prosthetic considerations. Implants are commonly used to replace congenitally missing lateral incisors in adolescent orthodontic patients. However, an interdisciplinary approach should be observed during the diagnosis, prognosis, and treatment plan to provide a result with good predictability and meet the esthetic and functional expectations of the patient. The present study describes a case of a young patient with tooth agenesis of maxillary lateral incisors, which was conducted with an integrated planning. After 5-year follow-up of 2 fixed implant-supported prostheses, clinical and radiographic examination showed the treatment to be successful.

Abstract
Angle Class II malocclusions may present morphologic deviations originated from the maxilla, mandible, or both. Since its reintroduction by Pancherz, the Herbst appliance has demonstrated effectiveness in the management of patients with mandibular deficiency. Because of the intermaxillary anchorage, the action of mandibular advancement provokes simultaneous reaction of maxillary restriction, similar to high-pull headgear. This aimed of this report is to compare two cases treated in two phases. In the first interceptive phase, the transverse problem was corrected by rapid maxillary expansion, which was followed by a Herbst appliance for mandibular advancement; in the second corrective phase, the cases were finished with fixed appliances. Although Herbst appliances were used in both patients, one patient with maxillary protrusion and another with mandibular deficiency, their use targeted different types of skeletal discrepancies. This difference allowed for the comparison of treatment effects, and although both patients had their malocclusion corrected, it seems reasonable to conclude that the final outcome was more favorable for the patient with maxillary protrusion.

Abstract
INTRODUÇÃO: o ortodontista clínico deve esperar alguma perda do alinhamento dentário obtido durante o tratamento ortodôntico nos casos em que a contenção ortodôntica foi suspensa pelo profissional ou perdida pelo paciente. Nessa situação, os pacientes são, frequentemente, relutantes em novamente usar braquetes para retratar o alinhamento dentário perdido após o tratamento. OBJETIVO: esse artigo descreve o uso de uma técnica simples e eficiente para corrigir pequenas alterações do alinhamento dentário. Esse procedimento, inovador e de baixo custo, produz a resolução da recidiva em poucas semanas. A força usada para realinhar os dentes é obtida através de um fio elastomérico transparente amarrado a uma contenção fixa, de vários filamentos, colada às arcadas superior e inferior.

Abstract
INTRODUÇÃO: a tração de dentes não irrompidos sempre foi considerada um procedimento de risco na prática ortodôntica. Com essa perspectiva, é indispensável a busca por eficiência nos procedimentos adotados para esse mister, o que justifica a proposta do presente artigo. Ao perfurar, vazamos uma estrutura natural, cuja restauração com material artificial é uma ação que está no escopo da área de maior evolução da Odontologia, não havendo justificativa para se evocar procedimentos de maior risco, como a colagem ou laçada com fios. OBJETIVO: este artigo objetiva apresentar protocolos para a Perfuração do Esmalte para o Tracionamento de Caninos (PETC), especificamente os caninos superiores, mais acometidos pelas anomalias de posicionamento, também denominadas disgenesias. Serão abordadas as vantagens e desvantagens da PETC em relação à Colagem de Acessório para o Tracionamento de Caninos (CATC), apresentando-se casos clínicos de diferentes níveis de complexidade, tendo como ponto de partida a literatura e a experiência clínica de 30 anos com elevado índice de sucesso.

Abstract
OBJETIVO: avaliar a concordância de ortodontistas treinados no diagnóstico do Padrão Facial, por meio da avaliação morfológica da face. MÉTODOS: foram utilizadas fotografias faciais de frente, perfil e sorriso de 105 indivíduos selecionados aleatoriamente entre pacientes que procuraram tratamento ortodôntico, as quais foram enviadas a ortodontistas treinados na classificação do Padrão Facial. A concordância intraexaminador, dos examinadores com o Padrão-Ouro e interexaminadores foi avaliada por meio do Índice Kappa. RESULTADOS: a concordância na avaliação intraexaminador foi quase perfeita, com Índice Kappa 0,85. A concordância entre os examinadores e o Padrão-Ouro foi moderada (Kappa 0,48), sendo mais alta no Padrão I (Kappa 0,62) e mais baixa no Padrão Face Curta (Kappa 0,33). A concordância entre os examinadores foi substancial (Kappa 0,61), mais alta que a concordância com o Padrão-Ouro em todos os Padrões. CONCLUSÃO: os critérios utilizados pelos examinadores para determinação do Padrão Facial foram os mesmos na primeira e na segunda avaliação. A concordância entre os examinadores e o Padrão-Ouro é moderada, e eles apresentam maior concordância entre si que com o Padrão-Ouro.

Abstract
OBJETIVO: o objetivo deste trabalho foi classificar e determinar a prevalência dos indivíduos portadores de comprometimento vertical nas relações faciais, conforme a severidade da discrepância e, especialmente, dos portadores de Padrão Face Longa. MÉTODOS: a amostra constou de 5.020 sujeitos de nacionalidade brasileira, de ambos os sexos, com idades entre 10 anos e 16 anos e 11 meses, matriculados no Ensino Fundamental do município de Bauru-SP. O exame da morfologia facial constou da observação direta da face, em normas frontal e lateral, sempre com os lábios em repouso, buscando identificar aqueles indivíduos que apresentassem comprometimento vertical nas relações faciais. Esses, uma vez identificados, foram classificados, considerando-se a severidade, em três subtipos: moderado, médio e grave. Para fins de determinação da prevalência dos portadores de Padrão Face Longa, apenas os classificados como dos subtipos médio e grave foram considerados. RESULTADOS: observou-se uma prevalência de 34,94% de comprometimento vertical nas relações faciais e 14,06% de Padrão Face Longa. CONCLUSÃO: os resultados obtidos no presente estudo permitiram concluir que a prevalência do comprometimento vertical nas relações faciais e do Padrão Face Longa foi maior do que a presumida com base na literatura.

Abstract
OBJETIVO: avaliar a influência da idade, do sexo, da relação oclusal sagital, do Padrão Facial e de 8 medidas do perfil facial sobre a estética do perfil. MÉTODOS: foram utilizadas tabelas de contingência, o Teste Qui-quadrado e o coeficiente de Cramér para avaliar a possível associação entre a nota dada por 32 avaliadores (14 ortodontistas, 12 leigos e 6 artistas) para a estética do perfil de 100 brasileiros - adultos, leucodermas, portadores de selamento labial passivo - e a idade, o sexo, a relação oclusal sagital, o Padrão Facial e as variáveis da análise facial numérica do perfil. RESULTADOS: não foi observada associação entre a idade, o sexo e a relação oclusal sagital e a estética do perfil facial. A associação foi observada entre a nota recebida para a estética do perfil e o Padrão Facial, o ângulo de convexidade facial e o ângulo do terço inferior da face. CONCLUSÃO: o Padrão Facial, definido na avaliação do perfil pela convexidade do perfil facial, e a projeção anterior do mento foram, entre os fatores avaliados, os determinantes para a estética do perfil facial.

Abstract
OBJETIVO: avaliar as alterações nas inclinações dos dentes anteriores causadas pelo tratamento ortodôntico, utilizando-se aparelho Straight-Wire, prescrição II Capelozza, antes e após a fase de nivelamento com fios ortodônticos de aço de secção retangular. MÉTODOS: foram selecionados 17 indivíduos adultos de padrão facial II, má oclusão Classe II, indicados para tratamento ortodôntico compensatório. As inclinações dos dentes anteriores foram avaliadas em três tempos clínicos, após o uso dos fios ortodônticos de diâmetros 0,020" (T1); 0,019" x 0,025" (T2) e 0,021" x 0,025" (T3), através de exames de tomografia computadorizada. Empregou-se a análise de variância de Friedman, com nível de significância de 5%, na comparação entre os tempos. RESULTADOS: observou-se que o fios retangulares empregados não foram capazes de produzir uma mudança significativa na mediana da inclinação dentária, exceto por uma discreta alteração nos incisivos laterais inferiores (p<0,05). Por outro lado, constatou-se que a variação das inclinações observadas era menor no fio retangular 0,021" x 0,025", principalmente para os incisivos superiores (p<0,001). CONCLUSÃO: fios retangulares 0,021" x 0,025" produzem uma maior homogeneidade no grau de variação na inclinação dos incisivos superiores, embora sem mudança significativa na sua mediana.

Abstract
OBJETIVO: definir valores cefalométricos esqueléticos e dentários para adolescentes brasileiros com Padrão Face Longa. MÉTODOS: a amostra foi constituída de telerradiografias em norma lateral de 30 pacientes com Face Longa, sendo 17 do sexo feminino e 13 do masculino; e 30 pacientes face Padrão I, 15 do sexo masculino e 15 do feminino, no estágio de dentadura permanente durante a adolescência. As características do Padrão Face Longa foram definidas clinicamente, pela análise facial. As seguintes grandezas cefalométricas foram avaliadas: (1) Comportamento sagital das bases apicais (SNA, SNB, ANB, NAP, Co-A, Co-Gn); (2) Comportamento vertical das bases apicais (SN.PP, SN.PM, ângulo goníaco, AFAT, AFAI, AFAM, AFP, AFATperp, AFAIperp); (3) Comportamento dentoalveolar (1-PP, 6-PP, 1-PM, 6-PM, 1.PP, IMPA); e (4) Proporção entre as alturas faciais (AFAIPerp/AFATPerp, AFAI/AFAT, AFAM/AFAI). RESULTADOS E CONCLUSÕES: o erro vertical na Face Longa concentra-se no terço inferior. A maxila apresenta uma maior altura dentoalveolar e a mandíbula, com morfologia mais vertical, mostra maior rotação no sentido horário. Essas características morfológicas e espaciais acarretam alterações sagitais e verticais no esqueleto e alterações verticais dentoalveolares. No sentido sagital, os ângulos de convexidade facial estão aumentados. No sentido vertical, as alturas faciais anteriores total e inferior estão aumentadas. O componente dentoalveolar está mais longo.

Abstract
OBJETIVO: o presente estudo cefalométrico longitudinal investigou as alterações espontâneas ocorridas em crianças com má oclusão Classe II, divisão 1, Padrão II. MÉTODOS: foram selecionadas 40 crianças, 20 meninos e 20 meninas, distribuídas na faixa etária compreendida entre 6 e 14 anos de idade. Para avaliar o comportamento das bases apicais, dos incisivos e do tecido mole, as seguintes grandezas cefalométricas foram mensuradas: SN.Ba, SNA, SNB, SND, SN.Pog, ANB, NAP, SN.PP, SN.GoGn, SN.Gn, Ar.Go.Gn, 1.PP, 1.NA, 1.SN, IMPA e ANL. As seguintes grandezas alcançaram significância estatística com o crescimento: SNB, SND,SN.Pog,ANB,NAP,SN.GoGn,SN.Gn,Ar.Go.Gn e IMPA. RESULTADOS: os resultados demonstraram que as principais alterações quantitativas registradas estavam relacionadas com o crescimento mandibular,independentemente do gênero. A mandíbula deslocou-se para frente, com tendência de rotação no sentido anti-horário e com conseqüente redução nos ângulos de convexidade facial. No entanto, as oscilações quantitativas nas grandezas cefalométricas não foram suficientes para mudar a morfologia dentofacial ao longo do período de acompanhamento. CONCLUSÃO: conclui-se, portanto, que a morfologia facial é definida precocemente e é mantida, configurando o determinismo genético na determinação do arcabouço esquelético.

Abstract
OBJETIVO: o presente estudo avaliou a hipótese de variação das características cefalométricas de acordo com o gênero para portadores de Padrão Face Longa. METODOLOGIA: foi analisado um total de 73 telerradiografias em norma lateral, sendo 34 Padrão Face Longa e 39 Padrão I (grupo controle), selecionadas com base na morfologia facial, sem considerar as relações oclusais. Foram avaliados: padrão de crescimento facial, alturas faciais anteriores e posterior, relação maxilomandibular, além das relações dentárias com suas bases apicais. RESULTADOS: o grupo controle (Padrão I) apresentou dimorfismo (p<0,001) no comprimento efetivo da maxila e da mandíbula, além das alturas faciais avaliadas. Foram significantes também (p<0,05) as proporções entre as alturas faciais e as distâncias entre os incisivos e molares em relação aos planos palatino e mandibular. Para os portadores de Padrão Face Longa, as mesmas variáveis cefalométricas não mostraram diferenças significantes entre os gêneros (p>0,05), exceto os comprimentos efetivos da maxila e da mandíbula, além da altura facial anterior inferior e posterior (p<0,05). CONCLUSÕES: concluiu-se que enquanto ocorreu dimorfismo nos indivíduos Padrão I, para as estruturas influenciadas pela diferença no tamanho esquelético entre os gêneros, isso não aconteceu nos portadores de Padrão Face Longa. Essa maior similaridade entre os gêneros provavelmente ocorreu porque a deformidade, mais grave no gênero feminino, foi suficiente para anular o menor tamanho esquelético esperado para estes indivíduos.

Abstract
OBJETIVO: o presente estudo teve como objetivo propor um método para classificação, segundo a severidade, dos indivíduos Padrão Face Longa, avaliando sua confiabilidade e reprodutibilidade. METODOLOGIA: foram utilizadas fotografias faciais (frontal, perfil e frontal sorrindo) de 125 crianças Padrão Face Longa (54 do gênero feminino e 71 do gênero masculino), selecionadas apenas considerando-se a morfologia facial, com idades entre 10 anos e 6 meses e 15 anos e 2 meses. As fotografias foram avaliadas, separadamente, por três examinadores, sendo reavaliadas após três semanas, em uma nova disposição aleatória. Os indivíduos foram graduados em três subtipos, de acordo com a severidade: moderado, médio e severo. Para avaliar as concordâncias intra e interexaminadores, foi utilizada a estatística Kappa (k). RESULTADOS: na avaliação intra-examinador, todos os examinadores obtiveram concordâncias substanciais, com o valor de Kappa variando de 0,64 a 0,66, havendo em todos os examinadores 80% ou mais de concordância. Quando comparadas as avaliações interexaminadores, as freqüências de concordância diminuíram, variando de 67,2% a 70,4%. A partir dos valores de Kappa, que variaram de 0,41 a 0,46, a interpretação foi considerada moderada. CONCLUSÕES: com base nesses resultados, o método foi considerado aplicável, com necessidade de complemento de informações provenientes de outros exames rotineiramente aplicados em Ortodontia. A aplicação clínica será demonstrada com intuito de evidenciar os níveis diferentes de severidade das más oclusões do Padrão Face Longa e as características do protocolo de tratamento recomendado.

Abstract
OBJETIVO: o objetivo do presente estudo foi determinar as medidas do perfil facial de brasileiros portadores de equilíbrio facial, denominados Padrão I. METODOLOGIA: a amostra foi constituída por 50 indivíduos (32 femininos e 18 masculinos), brasileiros, adultos, leucodermas, com idade média de 23 anos. Fotografias padronizadas do perfil foram obtidas. Sobre essas foram executados os traçados por dois avaliadores, que verificaram: 1) ângulo nasolabial; 2) ângulo mentolabial; 3) ângulo interlabial; 4) ângulo de convexidade facial; 5) ângulo de convexidade facial total; 6) ângulo do terço inferior da face; 7) proporção entre a altura facial anterior média e a altura facial anterior inferior e 8) proporção do terço inferior da face. RESULTADOS E CONCLUSÕES: não houve diferença estatística relevante entre as duas medidas realizadas. Os valores de média, desvio-padrão, valores máximos e mínimos obtidos para cada variável estudada foram: 1) ângulo nasolabial: 108,13° ± 9,75° (81° a 127°); 2) ângulo do sulco mentolabial: 132,37° ± 9,82° (110,5° a 152°); 3) ângulo interlabial: 135,35° ± 11,14° (116,5° a 159,5°); 4) ângulo de convexidade facial: 12,32°± 3,93° (4° a 19,5°); 5) ângulo de convexidade facial total: 137,85° ± 4,08° (129,5° a 147,5°); 6) ângulo do terço inferior da face: 103,41° ± 8,12° (88° a 124°); 7) proporção entre os terços médio e inferior da face: 0,93 ± 0,10 (0,80 a 1,21) e 8) proporção do terço inferior da face: 0,45 ± 0,06 (0,30 a 0,67). Propõe-se esse conjunto de medidas como um padrão de referência para avaliação facial numérica de adultos, brasileiros, brancos.

Abstract
Tooth transpositions present at a relatively low incidence in the world population and primarily affect maxillary canines and premolars. Treatment of this disturbance should take into account aspects such as facial pattern, age, malocclusion, tooth-size discrepancy, stage of eruption, and magnitude of the transposition. Mechanics for correction should be entirely individualized, reducing the risks and adverse effects. Practitioners often select simpler options, indicating extraction of permanent teeth, which is an irreversible procedure that may bring about damages to the patient. This study presents a case report and treatment of unilateral transposition of maxillary canine and premolar with repositioning of affected teeth to their respective normal positions.
