In this study a surface penetrating sealant was used around bonded stainless steel orthodontic brackets. The investigation attempted to identify the effect of surface penetrating sealants on the microleakage associated with orthodontic stainless steel brackets bonded with light cured composite resin. A total of 58 bovine teeth were used for this study, orthodontic brackets were bonded with light cured orthodontic resin. The following groups were assigned: (I) Finished but unsealed, (II) Finished and sealed, and (III,) Un-finished but unsealed The brackets were activated using orthodontic elastics, stained, sectioned, and evaluated under magnification. The following statistical analysis was done Mann-Whitney U test for two independent samples, then confirmed with a Kruskai-Wallis One-Way analysis of variance by ranks. The second and third groups were statistically better in respect of marginal integrity as compared to the first.

Abstract Since turn of the 20th century orthodontic diagnosis and treatment planning has been based on the Angle paradigm that considers ideal dental occlusion ‘nature's intended ideal form’. The orthodontist's task is to seek balance between the patient's aesthetic demands, functional efficiency and structural harmony. The soft tissues largely determine the limitations of orthodontic treatment, from the perspectives of functions and stability, as well as aesthetics. Therefore orthodontist must plan treatment within the patient's limits of soft tissue adaptation and soft tissue contours. This is a case report showing a well finished case keeping in mind the emerging soft tissue paradigm in diagnosis and treatment planning.

ABSTRACT Objectives: To examine the satisfaction of patients with their orthodontic treatment at the Department of Orthodontics at the Academic Centre for Dentistry Amsterdam (ACTA) in The Netherlands. Materials and Methods: To analyze differences in satisfaction through time, the results of patients treated at ACTA in 2008 and 2009 were compared with the results of patients treated at ACTA in 2000. A validated questionnaire about patient satisfaction was used. The total scale was divided into six subscales. A questionnaire was sent to all patients younger than 30 years who finished orthodontic treatment in 2008 and 2009 at ACTA. Results: The internal consistency of the total scale and the six subscales of the questionnaire was satisfactory. Respondents scored highest on items about satisfaction with the doctor-patient relationship (mean 4.24; SD 0.63) and lowest on items regarding their satisfaction with psychosocial improvement (mean 2.88; SD 0.87). Compared to the results of the sample from 2000, significant differences were found on the subscales doctor-patient relationship, residual category, and psychosocial improvement as well as on the total sum scale. Conclusions: The doctor-patient relationship remains the most important factor contributing to patient satisfaction. However, the results show that, overall, patients are more satisfied with their orthodontic treatment than patients were a decade ago.

ABSTRACT Obtaining long term stability allied to functional and aesthetic balance is the main goal of any orthodontic-orthopedic therapy. This case report describes the orthodontic therapy applied to a 7-year-9-month old child, who presented a Class II, division 1 malocclusion associated to skeletal open bite. Functional and skeletal corrections (sagittally and vertically) were obtained by means of mandible advancement achieved with a closed Balter’s bionator appliance followed by a fixed appliance. This approach showed to be efficient in accomplishing both functional and aesthetic goals, that were kept stable five years after the treatment was finished. This case report was presented to the Board of Directors of the Brazilian Board of Orthodontics and Facial Orthopedics (BBO), as partial requirement to becoming a Diplomate of the BBO.

The American Board of Orthodontics (ABO) was founded nearly ninety years ago as the first American specialty board in the field of dentistry. The ABO, in affiliation with the American Association of Orthodontists, is, in fact, the only orthodontic specialty board that is recognized by the American Dental Association. In order to become board-certified by the ABO, an orthodontist must successfully pass a written examination as well as a clinical examination. Important to the clinical exam is the ability to measure case complexity and case outcome. To this end, the ABO has established a comprehensive Discrepancy Index (DI) system which systematically analyzes and scores every element of the selected case and its difficulty, thereby measuring case complexity. Similarly, the ABO has established a comprehensive Cast-Radiograph (CR) evaluation which systematically analyzes every element of the selected case and its finished occlusion, thereby measuring case outcome. This review article presents an overview of the ABO certification process and reviews a classic high-angle Class II growing patient case that successfully passed the ABO exam. This article further presents a walkthrough of how to complete the DI and CR evaluation using the high-angle Class II growing patient case as an example. By establishing the DI form and CR evaluation and by making this information available to the public, the ABO strives to be both objective and transparent in allowing orthodontists to self-assess their finished cases.

The orthodontic minitubes system (FLOWJAC ® System, Bogotá, Colombia) is an innovating system that blend the selfligating philosophy techniques and a lowprofile appliance. The FLOWJAC® System works with low orthodontic forces, same as selfligation devices. The system uses heat-treated wires with better physical properties such as hysteresis when is compare with traditional wires. However, the FLOWJAC® technique doesn´t use a wire sequence to get a “working wire”, just a 0,014 Copper NiTi. The clinician in each appointment must modify the minitube location to the clinical desire teeth position. The present report blend FLOWJAC® devices in the upper arch and clear selfligation in the lower arch. The patient treated has mandibular bone resorption due a alloplastic chin augmentation. The root apex from first right premolar to the first left premolar seen to be near to the resorption area using Cone Beam Computer Tomography. That´s the reason why we use a pre-adjust devices in the lower arch, to avoid pulpar and periodontal counter effects. This case was finished with proper functional and aesthetics objectives; such as molar and canine class I, anterior open bite closure with 20% of overbite, coincidence of dental smile arch with lower lip, and without root and pulpar counter effects. The porpoise of this report is to present an orthodontic case with bone resorption on right premolar and incisors area of the mandible. The case was treated with selfligation orthodontics system; FLOWJAC® System in the upper arch and Empower Clear® (American Orthodontics Shebboyiang, USA) in the lower arch and could be done with a precise diagnosis and adequate treatment planning.

Proposition: The purpose of this study was to evaluate in vitro the color changes of esthetic orthodontic elastomeric ligatures of different shades when exposed to four food colorings commonly found in the diet of patients. Materials and Methods: The sample consisted of esthetic orthodontic elastomeric ligatures in the colors pearl, pearl blue, pearl white and colorless, which were immersed for 72 hours in five different solutions: distilled water (control group), coffee, tea, Coca-Cola ® and wine. The color changes of the esthetic orthodontic elastomeric ligatures were measured with the aid of a spectrophotometer, at T1 - as provided by the manufacturer; and T2 - after colorings process. Results: The results indicated that the esthetic orthodontic elastomeric ligatures of all initial hues are susceptible to pigmentation. Among the evaluated colors, all changed the finished look and the color of the samples tested. In ascending order, the color of the samples was as follows: distilled water, Coca-Cola®, black tea, wine and coffee. Conclusion: The substances that have a greater potential for pigmentation in esthetic orthodontic elastomeric ligatures were black tea, wine and coffee, respectively. All shades of esthetic orthodontic elastomeric ligatures are susceptible to color change.

Introduction: The objective of this study was to determine whether recently developed fiber reinforced composite burs provided better results by comparing tooth discoloration after debonding of orthodontic brackets.Methods: A split-mouth, randomized controlled trial was carried out in one orthodontic office; including 23 patients with intact, vital and caries-free four upper incisors aged 12 to 30 years who completed their fixed orthodontic treatment. For each patient, upper central and lateral incisors on each side of the mouth were randomly selected to remove the adhesive with either a tungsten carbide bur (TC) (n = 46) or a fiber-reinforced composite bur (FC) (n=46). Color evaluation of each tooth was conducted at two time points: immediately after finishing and polishing procedure and two months afterwards. The primary outcome would be the amount of color change in each group during the post treatment phase. The participants, the person assessing the color change and the statistician were blinded to TC group assignment. Color changes in each group were analyzed with the Paired T-test. The color change corresponding to the resin removal method was also statistically analyzed with the Independent T-test at ?=0.05 as the level of significance.Results: 86 teeth, 43 in each group, were analyzed. The ?E value was 3.713±1.161, for teeth finished TC and 2.114±0.514 for teeth finished with FC (p<0.01).Conclusion: adhesive removal with FC bur results in a more color-resistant tooth surface in comparison with tungsten carbide bur.

Objective: To assess the orthodontic burden of care of patients from a Brazilian rehabilitation center (Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo [HRAC-USP]). Design: Retrospective. Setting: Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo. Interventions: One hundred files of unilateral complete cleft lip and palate patients who had consecutively finished orthodontic rehabilitation at HRAC-USP were evaluated from January 2011 to January 2013. The duration of orthodontic treatment, number of visits, kilometers traveled, number of appliances and surgical procedures performed were recorded. The sample was divided into 2 subgroups according to severity the interarch relation (Goslon Yardstick score) at the beginning of orthodontic treatment. Mann-Whitney test was applied for intergroup comparison ( P < .05). Results: For the total sample (n = 100), the mean time of orthodontic treatment was 140.2 months, the mean number of orthodontic appointments was 61.8, the mean number of appliances was 10, the mean number of surgical procedures was 6.2, and the mean distance traveled to attend the center for orthodontic appointments was 38,978.5 km. The subgroup with the most severe malocclusion (Goslon yardsticks scores 4 and 5) showed a longer orthodontic treatment length, greater number of surgical procedures, and longer distance traveled than those presenting Goslon yardstick scores 1, 2, and 3. Conclusion: Patients with greater severity of the initial malocclusion experienced a higher burden of care than patients with less severity of the initial malocclusion. To reduce the burden of care, research and efforts should focus on minimizing maxillary growth deficiency related to primary surgery.

Aim of the study was to evaluate gingival modifications occuring in patients during orthodontic treatment with fixed appliances. Materials and methods. After inclusion and exclusion criteria were applied, in study were included 60 patients (35 girls and 25 boys). Mean age was 13.1 years for girls and 12.8 years for boys. Treatment period was 19.2 months for the upper arch and 21.3 months for the lower arch. There were taken 2 types of measurements ː plaque index (PI) and gingival index (GI), before, during and after treatment. Results. During orthodontic treatment buccal GI was 1.35 ± 0.32 and interpoximal GI was 1.75 ± 0.25. PI was 0.85 ± 0.28. After the appliances were removed, buccal GI was 1.44 ± 0.37, inteproximal GI 1.86 ± 0.22 and PI 1.01 ± 0.29. When PI and GI were measured in individual teeth it was found a statistical correlation in the measured values (p≤0.05). Conclusions. Based on these results we conclude that gingival modifications occur during orthodontic treatment. The most important changes are in the lower arch in molar area. After the treatment is finished, the situations come back in normal parameters.

O objetivo deste estudo retrospectivo foi buscar variáveis oclusais relacionadas com o prognóstico da estabilidade da correção da má oclusão de Classe II, tratada sem e com extrações. Para tanto, foram selecionados 78 registros de documentações, pertencentes ao arquivo da disciplina de Ortodontia da Faculdade de Odontologia de Bauru, com má oclusão inicial de Classe II completa bilateral, divisão 1, tratada pela mecânica Edgewise e acompanhada por um período médio de 10 anos póstratamento. Essa amostra foi dividida em três grupos, de acordo com o protocolo de tratamento: Grupo 1: constituído por 25 pacientes, com idade inicial média de 12,74 anos, tratados sem extrações, por um período médio de 2,41 anos; Grupo 2: contendo 25 pacientes, com idade inicial média de 13,42 anos, tratados com extrações dos primeiros pré-molares superiores, por um período médio de 2,10 anos; Grupo 3: composto por 28 pacientes, com idade inicial média de 12,98 anos, tratados com extrações dos primeiros pré-molares superiores e primeiros ou segundos pré-molares inferiores, por um período médio de 2,10 anos. As avaliações oclusais foram realizadas em modelos de gesso dos pacientes, nas fases inicial (T1), final de tratamento (T2) e na fase pós-tratamento (T3), utilizando os índices PAR e de irregularidade de Little. O percentual de redução do índice PAR, durante o tratamento, foi de 72,58% para o grupo 1, 80,17% para o grupo 2 e 79,37% para o grupo 3. Para comparação intergrupos, utilizaram-se a análise de variância a um critério e o teste não paramétrico do Qui-quadrado. Os grupos apresentaram-se semelhantes quanto ao gênero, idades (fases T1, T2 e T3), tempo de tratamento, percentual de redução do PAR, eficiência do tratamento e no tempo pós-tratamento. A única variável oclusal responsável pela ausência de uma finalização ortodôntica de excelência (PAR T2 = 0) e pela recidiva evidenciada na fase pós-tratamento, foi a oclusão posterior. Ao separar a amostra em grupos bem finalizado (50 pacientes com o PAR T2 5) e mal finalizado (28 pacientes com PAR T2 > 5) em relação às alterações ocorridas no período pós-tratamento (PAR T3 - T2 e Little T3 T2), verificou-se por meio do teste t independente, que ambos os grupos foram estatisticamente semelhantes em relação à recidiva; no entanto, uma boa finalização ortodôntica proporcionou melhores resultados oclusais e funcionais, nas fases T2 e T3. A recidiva do apinhamento ântero-inferior (Little T3 T2) não correlacionou-se com as alterações oclusais ocorridas no período pós-tratamento (PAR T3-T2).<br>The objective of this retrospective study was to seek oclusal variables related to correction of Class II malocclusion stability prognosis, treated without and with extractions. As such, 78 documentation records were selected, belonging to the Orthodontic Department from the Bauru Dental School, with an initial complete bilateral malocclusion of Class II, division 1, treated with Edgewise mechanics and followed up for an average period of 10 years post-treatment. This sample was divided into three groups, according to the treatment protocol: Group 1: consisted of 25 patients, with average initial age of 12.74 years, treated without extractions, for an average period of 2.41 years; Group 2: consisted of 25 patients, with an average initial age of 13.42 years, treated with extractions of the first superior premolar teeth, for an average period of 2.10 years; Group 3: consisted of 28 patients, with an average initial age of 12.98 years, treated with extractions of the first superior premolar teeth and first or second inferior premolar teeth, for an average period of 2.10 years. Occlusal evaluations were done on the patients cast models, at the initial phase (T1), at the end of treatment (T2) and post-treatment phase (T3), using the PAR index and Little irregularity index. The percentile reduction for the PAR index, during the treatment, was 72,58% for group 1, 80,17% for group 2 and 79,37% for group 3. For the intergroup comparisons, one-way ANOVA and the non-parametric Chi-square tests were used. The groups were similar regarding gender, ages (phases T1, T2 and T3), time of treatment, PAR reduction percentile, treatment efficiency and post-treatment duration. The only occlusal variable responsible for the absence of excellent orthodontic finalization (PAR T2 = 0) and by relapse evidenced in the post-treatment phase, was the posterior occlusion. When separating the sample in groups well finalized (50 patients with PAR T2 5) and with bad finalization (28 patients with PAR T2 > 5) in relation to the alterations occurred in the post-treatment period (PAR T3 - T2 and Little T3 - T2), it was verified by using an independent t test that both groups were statistically similar in relation to relapse, however, good orthodontic finalization provided better occlusal and functional results in phases T2 and T3). Anterior inferior crowding relapse (Little T3 T2) did not correlate with the occlusal alterations occurred in the post-treatment period (PAR T3 -T2).
