RESUMO
BACKGROUND: Well-planned orthognathic surgery improves psychological health, aesthetics and function of patients. AIM: The present study aimed to investigate patients' satisfaction after orthognathic surgery by means of a satisfaction questionnaire before and after surgery. MATERIALS AND METHODS: A total of 29 patients was selected (17 women and 12 men), with a mean age of 28 years, randomly selected from a private clinic at Araçatuba - São Paulo by two investigators. Anamnesis and clinical examination were performed. Subjects with facial deformities submitted to orthodontic treatment before and after orthognathic surgery with a minimum post-surgery period of 6 months, answered a satisfaction questionnaire composed of 10 questions regarding dental and facial aesthetics. In this study, the maximum satisfaction score was 10. RESULTS: Regarding aesthetics, two satisfaction parameters were investigated: dental and facial. For all indices, the average satisfaction was up to score 7. CONCLUSION: According to the results, it can be concluded that orthognathic surgery has been an effective treatment for dentofacial deformities, aesthetics and functional problems, what was verified by pre and postoperative questionnaire application.
RESUMO
Impaction of maxillary canines can be prevented by early intervention in the mixed dentition phase after the correct diagnosis of malocclusion, reducing the complexity of the treatment. This article reports the case of a 10-year-old patient who possessed impacted maxillary canines and, after early extraction of primary canines, had reestablished favorable permanent successors' eruption axis. This 5-year radiographic follow-up study with panoramic radiography shows that this can be used in practice and that an effective control strategy ensures the accuracy in the inclination of the impacted canines. Treatment success is related to early diagnosis and strategic interceptive treatment choice.

The purpose of this study was to evaluate, in vitro, the chromatic behavior of esthetic brackets stored in potentially staining solutions. The sample were divided into four groups according to the commercial brand and stored in four different solutions (distilled water, cola soda, coffee and mouthrinse) at 37°C for 14 days. Possible color changes measured according to the CIE L*a*b* color system with a spectrophotometer at five intervals of time after storage. The statistical analysis was carried out using ANOVA to 1%, TukeyÆs tests and decomposition of interactions with a significance level of 5%.The color changes were dependent on the solution, storage time and the brand of brackets. The largest color changes were observed in the G3, followed by G2. The esthetic brackets do not present satisfactory and stable chromatic behavior

Objetivo: O objetivo deste estudo clínico controlado foi avaliar os efeitos da expansão da maxila com o aparelho Hyrax modificado sobre a dimensão transversal da maxila em níveis esquelético basal, alveolar e dentário por meio da tomografia computadorizada de feixe cônico. Materiais e Métodos: Oito pacientes com média de idade de 7 anos e 1 mês, portadores de mordida cruzada posterior unilateral funcional foram submetidos a um tratamento ortodôntico por meio de um aparelho expansor fixo, seguindo um protocolo clínico com ativações do parafuso de dois quartos de volta por dia até atingir a sobrecorreção das mordidas cruzadas. Foram obtidas tomografias pré-expansão (T1) e pós-contenção (T2), caracterizado por um período de 5 meses pós-expansão. Sobre estas tomografias foram realizadas medidas da base maxilar, da distância entre as cristas alveolares e da distância intermolares vestibulares e palatinas. Resultados: Os resultados mostraram um aumento percentual em todas as dimensões lineares transversais, com uma diminuição da magnitude dos efeitos dentários (6%) para o osso basal (2,1%). Conclusão: A expansão da maxila foi obtida como efeito geral pós-tratamento, sendo a expansão predominante no aspecto dentário
Purpose: The present controlled clinical trial aimed to investigate the effects of maxillary expansion with modified Hyrax device on the transversal dimension of maxilla in the skeletal, dento-alveolar and dental levels by using a cone beam computerized tomography (CT). Materials and Methods: Eight patients (mean age of 7 years and 1 month) with functional unilateral posterior crossbite were subjected to orthodontic treatment with fixed expansion appliance. The activation of the screw was two-quarter turns per day. CT scan was conducted in the pre (T1) and pos (T2) treatment. The maxillary base, the distance between the alveolar ridges, and the intermolar buccal and palatine distances were measured. Results: An increase of all linear transverse dimensions, decreasing in magnitude from dental (6%) to basal bone (2.1%). Conclusion: Maxillary expansion was observed after treatment in which the dental aspect was the most predominant expanded
