OBJETIVO E METODOLOGIA: o presente estudo prospectivo objetivou analisar cefalometricamente as alterações dentoesqueléticas e do perfil tegumentar após o tratamento ortodôntico de casos com extrações dos quatro primeiros pré-molares. A amostra consistiu de 30 jovens de ambos os gêneros, com idade média inicial de 12 anos e 4 meses, portadores de má oclusão Classe II, 1ª divisão de Angle. As principais referências do trabalho concentram-se nas grandezas cefalométricas dos incisivos superiores e inferiores em relação às coordenadas vertical e horizontal, bem como às alterações dos lábios e ângulo nasolabial pré e pós-tratamento. RESULTADOS: os resultados demonstraram que houve retração média dos incisivos superiores de 3,4mm e dos inferiores de 1,8mm. O ponto A sofreu discreta alteração devido à retração dos incisivos superiores, discriminada pela diminuição média do ângulo SNA (1,7 graus). Houve melhora na relação maxilomandibular, demonstrada pela diminuição das grandezas Wits e ANB. Não houve diferenças estaticamente significantes para as grandezas cefalométricas SN.GoGn e SN.GoMe, embora a altura facial ântero-inferior tenha aumentado, em decorrência do crescimento craniofacial normal. Observou-se que para cada 1mm de retração dos incisivos superiores...

INTRODUÇÃO: torna-se difícil, sem a utilização de um índice oclusal, uma avaliação fidedigna dos resultados e da finalização dos tratamentos ortodônticos. O índice PAR é capaz de avaliar objetivamente as alterações que ocorrem com o tratamento ortodôntico, e as melhorias conseguidas. OBJETIVO: por isto, decidiu-se, neste estudo, avaliar-se as alterações decorrentes dos tratamentos ortodônticos realizados com aparelho fixo, mecânica Edgewise e com extrações dos quatro primeiros pré-molares, bem como a qualidade de sua finalização e de seus resultados, por meio do índice de avaliação oclusal PAR. MATERIAL E MÉTODOS: foram avaliados os modelos de estudo de 94 pacientes leucodermas, com idade média de 13,46 anos, sendo 50 do gênero masculino e 44 do feminino. O tempo de tratamento médio foi de 2,09 anos. O índice PAR foi obtido dos modelos pré e pós-tratamento de cada um dos pacientes. RESULTADOS: após a realização da análise estatística descritiva, pode-se observar que o índice PAR inicial médio de 29,46 foi reduzido para 6,32 ao final do tratamento, caracterizando uma redução de 78,54% com o tratamento ortodôntico. Houve correlação do índice PAR inicial com a correção deste índice durante o tratamento. CONCLUSÃO: pode-se concluir que os casos tratados demonstraram um bom padrão de finalização ortodôntica...

O Índice Dental Estético (DAI) tem sido amplamente usado em estudos envolvendo crianças e adolescentes, mas raramente usado em estudos com adultos. O propósito do presente estudo transversal foi avaliar a confiabilidade do DAI em uma amostra com 120 pacientes adultos, incluindo 46 do sexo masculino (38,3%) e 74 do sexo feminino (61,7%), entre 19 e 78 anos de idade (média de 49,2). Quase todos os pacientes apresentaram-se com muitas perdas dentárias e sem tratamento ortodôntico prévio. A prevalência e a severidade da má oclusão, a necessidade de tratamento ortodôntico, a autopercepção do paciente em relação à necessidade deste tipo de tratamento e a indicação, pelo cirurgião-dentista, foram avaliadas. Além disso, as opiniões subjetivas de 33 ortodontistas em 32 pacientes, por meio de fotografias intra e extrabucais e modelos de estudo foram também analisadas. Teste estatístico Kappa foi usado para avaliar o DAI e as opiniões dos profissionais. Testes qui-quadrado e de Fischer foram usados para verificar a correlação entre sexo, autopercepção e indicação do cirurgião-dentista e o escore do DAI. O teste t-student foi usado para investigar a correlação entre a idade e a necessidade de tratamento ortodôntico. A média do escore DAI foi de 38...

To assess the occurrence, extension, and severity of gingival margin alterations in a sample of youth after orthodontic treatment. Records from 209 Caucasian adolescents (118 female and 91 male) before and after orthodontic treatment were selected. Patients presented a mean age at the beginning of orthodontic treatment of 11.20 ± 1.86 years and a final mean age of 14.72 ± 1.83 years. Class I and II patients with mandibular incisors and canines that were completely erupted and with spacing or crowding not exceeding 4 mm were evaluated. The presence of gingival recession on the labial surface of the mandibular anterior teeth was evaluated in intraoral photographs and casts made before and after treatment. The proportion of patients with gingival recession after treatment was statistically higher than at the beginning (P<.001). After orthodontic treatment, gingival recession was not present in any of the teeth for 63.6% of the patients; in 29.2% of the patients, recession was present in at least 1 tooth. In terms of severity, the majority of affected teeth (47%) presented gingival recession less than 2 mm and in 2% more than 4 mm. It may be concluded that alterations in the gingival margin, especially gingival recession, occur in patients after orthodontic therapy...

The purpose of this study was to address the therapeutic goals regarding the static and functional occlusion in the completion of orthodontic treatment. For such purpose, a study population comprising 20 female treated Class II malocclusion subjects with an initial mean age of 11 years underwent a two-phase treatment (orthopedics and orthodontics). The patients were diagnosed in centric relation and were treated according to the six keys for normal occlusion and functional occlusal parameters (centric relation, vertical dimension, lateral and anterior guidances, occlusal contacts and direction of forces applied on the teeth). After removal of fixed mechanics, retainers were installed and maintained for two years. Five years after orthodontic completion, the occlusal stability of the patients was evaluated regarding molar relationship and overjet, measured in dental casts. All subjects maintained the normal molar relationship and correct overjet achieved at the end of treatment, indicating a fair level of occlusal stability. The importance of the criteria of the ideal functional occlusion to ensure a better stability after completion orthodontic treatment will be discussed in detail in this paper. In addition, some clinical situations in which localized adjustments are indicated for occlusal refinement will be described.

INTRODUCTION: The possibility that orthodontic treatment in childhood might be a risk factor for the development of temporomandibular disorders (TMD) later in life has been an issue of great controversy in dental literature. OBJECTIVE: To determine a possible negative or positive correlation between orthodontic treatment and TMD by presenting the results and conclusions from a number of key-papers dealing with this subject. RESULTS AND CONCLUSION: According to current knowledge, there is no scientific evidence to support that orthodontic treatment is a risk factor for the development of TMD. On the other hand, there is some evidence to support that a proper orthodontic treatment performed in childhood might have a positive effect upon the functional status of the masticatory system later in life.

With regard to the best moment for carrying out or recommending dental bleaching to orthodontic patients, some explanations and orientations are given in order to answers the following questions: 1) Why orthodontic treatment completion is considered the best opportunity for carrying out the procedure? 2) Why dental bleaching should not be performed immediately before orthodontic treatment? 3) If that would be possible at any special case, what would that be? 4) Why dental bleaching should not be performed during orthodontic treatment? 5) If that would be possible at any special case, what would that be? This article highlights why it is essential to protect both the mucosa and the cervical region, regardless of the moment when dental bleaching is performed, whether associated with orthodontic treatment or not. The "how", "why" and "if" of whether or not it is convenient to perform dental bleaching before orthodontic treatment are still a matter of clinical suggestion, as it is a procedure that is under analysis, empirical knowledge waiting for scientific proof or disproof! Although tooth enamel has adamantine fluid flowing within it, providing a specific metabolism that is peculiar to its own and which could scientifically explain and base the option of carrying out teeth whitening before and during orthodontic treatment...

Objective: To determine the frequency of apical root resorption in different tooth groups after the end of orthodontic treatment, detected by cone beam computed tomography. Methodology: Images of cone beam computed tomography of 30 patients who had Class I malocclusion and crowding were obtained before and after orthodontic movement. The treatment with fixed appliances was developed based on the Roth prescription. A total of 1256 dental roots were evaluated based on the measurement of linear length between root apex and incisal/cusp. It was an epidemiological, prospective, longitudinal and intra individual study. Results: The mean age of patients was 13 years, 11 were male and 19 female. One hundred percent of the patient presented teeth with apical root resorption, 46% of the roots avaluated was affected. The teeth showed higher extent of apical root resorption were upper lateral incisors, lower lateral, upper central, lower central, upper and lower first molars (p <0.05). By analyzing the roots individually, there was a high frequency of apical root resorption in maxillary central incisors (73%), maxillary lateral incisors (73%), mandibular central incisors (72%), mandibular lateral incisors (70%) and distal roots of mandibular first molar (63%). There was a low frequency of apical root resorption in the buccal roots of the maxillary second premolar (17%)...

Aim: To detect Apical Root Resorption (ARR) after orthodontic treatment at 52-288 months using periapical radiography (PR) and cone beam computed tomography (CBCT). Methods: Radiographic images obtained from 58 patients, before (T1) and after orthodontic treatment (T2), and following 52-288 months of treatment were analized by three members of the Brazilian Board of Orthodontics. Apical structures were evaluated by PR images (T2 and T3), using Levander and Malmgren2 scores. The presence of ARR on CBCT images were detected only at T3. The Kolmogorov-Smirnov test was used for statistical analyses, and the level of significance was set at 5%. Kappa statistics determined interobserver agreement. Results: ARR more frequent were with scores 1 in T2 (51.6%) and T3 (53.1%), when evaluated by PR (p>0.05). When compared the frequencies of ARR in T3 among PR and CBCT images, the differences were significant for maxillary and mandibular pre-molar groups, and for mandibular molar group (p>0.05). The teeth with highest frequency of ARR presence using CBCT images were maxillary lateral incisors (94.5%) and mandibular central incisors (87.7%), while the bicuspids showed the lowest frequency. The CBCT images showed that the teeth involved in orthodontic treatment with extraction present higher ARR frequency (p<0.05). Conclusion: PR images suggested higher frequency of ARR compared with CBCT images for maxillary and mandibular pre-molar groups...

An understanding of the determinants of the provision of fixed orthodontic treatment would be beneficial in the planning of any system aimed at rationalising supply. The aim of this longitudinal study was to determine those factors which were predictive of the provision of fixed orthodontic treatment in adolescents. Baseline data, at age 13 years, on oral health, the history of orthodontic consultation and interceptive orthodontic care, a dental appearance score (DAI), socio‐demographic characteristics and self and parental perceptions of both dental appearance and need for fixed orthodontic treatment were obtained from 2793 adolescents under the care of the South Australian School Dental Service who had not undergone fixed orthodontic treatment. Data on the orthodontic care provided to these adolescents in the ensuing 2 years were collected. At the end of the 24‐month period 433 adolescents (15.5%) had undergone fixed orthodontic treatment. Significant bivariate associations were found between the provison of fixed orthodontic treatment and the DAI score, sex of the adolescent, familial history of fixed orthodontic treatment, income, private insurance, orthodontic consultation and interceptive orthodontic care before the age of 13 years and self and parental perceptions of both dental appearance and the need for fixed orthodontic treatment. Logistic regression was used to produce a predictive model of fixed orthodontic treatment. The model explained 30.2% of the variance...

INTRODUCTION: Estimating orthodontic treatment need in the permanent dentition using information from the deciduous-dentition malocclusion may assist in defining the time for appropriate orthodontic intervention. Our objective was to investigate whether malocclusion in the deciduous teeth predicts orthodontic treatment need in the permanent dentition. METHODS: Two oral health studies nested in a birth cohort were carried out at ages 6 (n = 359) and 12 (n = 339) years. Open bite, crossbite, and canine malocclusion were assessed in the deciduous teeth. Orthodontic treatment need was determined in the permanent dentition using the dental esthetic index. Prevalence ratios were estimated using 2 dental esthetic index cutoff points: highly desirable/mandatory orthodontic treatment and only mandatory orthodontic treatment. We tested all combinations of the deciduous malocclusion and the outcomes, controlling for confounders. RESULTS: Children with only open bite and those with concurrent open bite and canine malocclusion were more likely to have either highly desirable/mandatory orthodontic treatment or only mandatory orthodontic treatment needs by age 12. The combination of crossbite and open bite in the deciduous teeth was associated with the highest risk of need for mandatory orthodontic treatment. CONCLUSIONS: Malocclusion in the deciduous teeth is a risk factor for orthodontic treatment need in the permanent dentition. Children with malocclusion at a young age should be monitored regularly...

Background:  There is little evidence to suggest that orthodontic treatment can prevent or reduce the likelihood of dental caries or of periodontal disease or dental trauma and temporomandibular disorders, but there is a modest association between the presence of malocclusion/orthodontic treatment need and quality of life. However, little is known of the long-term outcomes of orthodontic treatment. This study reports on the longitudinal follow-up of quality of life and psychosocial outcomes of orthodontic treatment among a cohort of adults who were examined as adolescents in 1988/1989. Materials and Methods:  Children who were examined in 1988/1989 were invited to a follow-up in 2005/2006. Respondents completed a questionnaire, which collected information on quality of life, receipt of orthodontic treatment and psychosocial factors, and were invited for a clinical examination. Oral health conditions including occlusal status using the Dental Aesthetic Index were recorded. Analysis of variance and multiple linear regression were used to examine the relationship between the measured factors. Results:  There was no statistically significant association between occlusal status at adolescence and quality of life at adulthood. Those individuals who had orthodontic treatment but did not need orthodontic treatment had higher self-esteem (23.1...

Background: Patients with cleft lip and/or palate (CL&/P) experience a higher caries prevalence. This study aimed to determine if patients with CL&/P, undergoing and not undergoing orthodontic treatment, have a different salivary biochemical profile and different salivary levels of Mutans Streptococci (MS) and Lactobacilli (LB) compared to patients undergoing and not undergoing orthodontic treatment without CL&/P. Methods: One hundred and ten subjects aged between 12 and 17 years were recruited into one of four different groups comprising two control groups and two treatment groups. The control groups comprised of subjects with and without CL&/P who were not undergoing orthodontic treatment. The treatment groups comprised of subjects with and without CL&/P undergoing orthodontic treatment. Regular reinforcement of oral hygiene instructions, dietary counselling and debridement, when necessary, were offered to subjects in the treatment groups following their orthodontic adjustment appointments. The salivary secretion time, pH of resting and stimulated saliva, salivary flow rate, buffering capacity, quantity of salivary MS and LB were measured. Results: Subjects with CL&/P undergoing orthodontic treatment at the Children's Oral Health Service tended to present with microbiological and salivary profiles that were less favourable for caries development. There was a significant difference in the percentage of subjects with >105 colony forming units (CFU)/mL of MS between the cleft treatment and non-cleft treatment groups. Subjects in the non-cleft treatment group had the highest percentage of subjects (86.7 per cent) with >105 CFU/mL of MS whereas subjects in the cleft treatment group had the lowest percentage of subjects (60 per cent) with >105 CFU/mL of MS. For LB...

Introduction: Les troubles respiratoires du sommeil (TRS), qui représentent une préoccupation croissante pour la santé, ont des effets significatifs sur la santé, le comportement et la performance académique chez l’enfant. Les malformations craniofaciales, l’hypertrophie adéno-amygdalienne et l'obésité, représentent des facteurs de risque importants dans le développement de cette condition. Les symptômes des TRS ont été étudiés dans une étude prospective chez les enfants et adolescents durant leur traitement orthodontique dans un milieu universitaire. Cette étude a cherché à décrire la prévalence et les facteurs de risque principaux des TRS, ainsi que l'impact des différentes interventions orthodontiques sur les symptômes TRS. Matériel et méthodes: dans une étude cohorte prospective, un groupe de 168 sujets âgés de 12 à 21 ans ont été soumis, quatre ans après la prise de données initiale, à un examen craniofacial en plus d'être administré des questionnaires qui ont recueilli des données sur la situation socio-démographique, le bruxisme et les troubles d’ATM, le sommeil et le comportement diurne, et les facteurs neuropsychologiques.

INTRODUCTION: The consensus about the relationship between TMD and orthodontic treatment has gone from a cause and effect association between TMD and orthodontic treatment to the idea that there is no reliable evidence supporting this statement. OBJECTIVE: To assess the beliefs, despite scientific evidence, of Brazilian orthodontists about the relationship between TMD and orthodontic treatment with regards to treatment, prevention and etiology of TMD. METHODS: A survey about the relationship between TMD and orthodontic treatment was prepared and sent to Brazilian orthodontists by e-mail and social networks. Answers were treated by means of descriptive statistics and strong associations between variables were assessed by qui-square test. RESULTS: The majority of orthodontists believe that orthodontic treatment not only is not the best treatment option for TMD, but also is not able to prevent TMD. Nevertheless, the majority of orthodontists believe that orthodontic treatment can cause TMD symptoms. CONCLUSION: This study suggests that orthodontists' beliefs about the relationship between orthodontic treatment and TMD are in accordance with scientific evidence only when referring to treatment and prevention of TMD. The majority of orthodontists believe that...

OBJECTIVES: The aim of this study was to observe the influence of orthodontic treatment on the hyoid position of patients with different vertical skeletal craniofacial patterns of mandibular deviations. METHODS: A total of 60 patients with mandibular deviations, including 30 males and 30 females with a mean age of 15.4 years, were recruited. They were equally divided into average angle, high angle, and low angle groups, with a 1:1 gender ratio. Their hyoid position was measured before and after orthodontic treatment. The data were analysed using paired ttests and analysis of variance (ANOVA). RESULTS: After treatment, the hyoid body in the high angle group presented significant forward and upward movements (p = 0.012 and p = 0.005). The hyoid body in the low angle group exhibited significant forward movement (p = 0.048) and a significant increase in the hyoid inclination (p = 0.00). In the average angle group, the hyoid body significantly moved downward (p = 0.031) and the thyrohyoid moved upward (p = 0.046). The ANOVA showed that orthodontic treatment significantly influenced the vertical position and inclination degree of the hyoid (F = 6.37, p = 0.003; F = 6.204, p = 0.004; and F = 3.393, p = 0.025). The average angle group displayed significant differences in these indices compared with the high angle and low angle groups. Orthodontic treatment significantly influenced the mandibular plane angle in the high angle group (p = 0.012). CONCLUSION: Orthodontic treatment influences the hyoid position of patients with different vertical skeletal craniofacial patterns of mandibular deviations by varying degrees.

OBJECTIVE: A study was done to estimate the orthodontic manpower requirements of Trinidad and Tobago. METHODS: A questionnaire was administered via e-mail to 9 of 11 orthodontists. Information from a population census, a report on the orthodontic treatment needs of children in Trinidad and Tobago and this questionnaire were used to calculate the number of orthodontists and chairside orthodontic assistants needed in Trinidad and Tobago. RESULTS: On average, 50 per cent of the 289 patients treated by each orthodontist in Trinidad and Tobago annually are children. Approximately, 13 360patients can be expected to demand orthodontic treatment every year in this country. The number of orthodontists and chairside assistants required to treat these patients was estimated to be 44 and 154, respectively. CONCLUSIONS: Currently, Trinidad and Tobago only has a quarter of the number of orthodontists and orthodontic chairside assistants required to treat the number of patients in need. As the demand is relatively high in Trinidad and Tobago and the number of orthodontists has increased slowly and inadequately for the past decade, the orthodontists are likely to remain adequately employed and happy with their job unlike dentists who are currently in private practice for less than a year.

OBJECTIVE: This prospective cross-sectional study was undertaken to determine the normative and perceived orthodontic treatment needs of children aged 11-12 years in a Caribbean country, Trinidad and Tobago. METHODS: One author, an experienced orthodontist, examined 367 children using the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN) to assess the normative need. The same orthodontist administered the questionnaire to assess the patient's perceived needs using the Aesthetic Component (AC) of the IOTN and the Oral Aesthetic Subjective Impact Scale (OASIS). RESULTS: The DHC and the AC of the IOTN and the OASIS showed respectively that 61.4%, 2.5% and 0.6% of the children had definite need for orthodontic treatment. The female proportion of the sample was more than the target population but the perceived need and normative need for orthodontic treatment did not depend significantly (p < 0.05) on the gender or ethnicity of the subjects of this study. The perception of need for orthodontic treatment differed inversely from the normative need and this is seen to be significant (p < 0.05) when OASIS was used. CONCLUSIONS: Approximately three out of five children in Trinidad and Tobago have a great (or very great) need for orthodontic treatment for dental health reasons.
