RESUMO
INTRODUCTION: Attention deficit-hyperactivity disorder is a behavioral disorder characterized by a lack of focus, impulsive behavior, and or excessive activity. This research aimed to evaluate the association between signs of attention deficit-hyperactivity disorder and malocclusion in schoolchildren. METHODS: A cross-sectional study was conducted with a representative sample of 633 children aged 7-12 years. The children were clinically examined for malocclusion using the Dental Aesthetic Index. The predominant breathing pattern was also determined. Parents answered a questionnaire addressing socioeconomic characteristics and the presence of nonnutritive sucking habits. The Swanson, Nolan, and Pelham Scale-IV was filled out by both parents and teachers to compare behavioral patterns. The children were submitted to a neuropsychological evaluation using the Raven's Colored Progressive Matrix Test. Data analysis involved the chi-square test and Poisson regression analysis. RESULTS: The prevalence of malocclusion was 42% higher among children with signs of hyperactivity reported by both parents and teachers (prevalence ratio [PR], 1.42; 95% confidence interval [CI], 1.11-1.81; P = 0.004). In the final Poisson regression model, the prevalence of malocclusion was lower among schoolchildren aged 11 and 12 years (PR, 0.62; 95% CI. 0.52-0.73; P <0.001) and higher among those who used a pacifier for at least 4 years (PR, 1.25; 95% CI, 1.02-1.54; P = 0.029) as well as those classified as mouth breathers (PR, 1.28; 95% CI, 1.09-1.51; P = 0.003). CONCLUSIONS: The prevalence of malocclusion was higher among children with signs of hyperactivity independently of age, pacifier use, and mouth breathing.

INTRODUCTION: An increasing percentage of the world's population has had access to orthodontic treatment within the last few decades. Consequently, a larger number of patients seeking for correction of their malocclusions, nowadays, present with a history of previous orthodontic therapy. Orthodontists performing retreatments in their practice may have to face additional difficulties, and one of them is treating individuals that may be even more demanding for excellent results and efficient treatments. OBJECTIVES: This manuscript discusses the challenges faced when performing orthodontic retreatments. It illustrates a two-phase retreatment of a pre-adolescent and the ortho-surgical retreatment of a young adult with high demands for fast and exceptional results. Finally, this paper elaborates on the positive impacts that these retreatments had on the patients' self-esteem and quality of life.

RESUMO Introdução: Um percentual crescente da população mundial vem tendo acesso ao tratamento ortodôntico ao longo das últimas décadas. Consequentemente, hoje em dia, um maior número de pacientes em busca da correção de suas más oclusões apresenta um histórico de tratamento ortodôntico prévio. Ortodontistas que realizam retratamentos ortodônticos podem enfrentar dificuldades adicionais, e uma delas é ter que lidar com indivíduos que apresentam demandas e expectativas ainda maiores em relação à obtenção de resultados excelentes e de forma bastante eficiente. Objetivos: O presente artigo discute os desafios e os impactos positivos do retratamento ortodôntico causados na autoestima e na qualidade de vida dos pacientes, e ilustra o retratamento em duas fases de uma pré-adolescente, e o retratamento ortodôntico-cirúrgico de uma paciente adulta jovem que tinha demandas muito elevadas para a obtenção de resultados rápidos e excelentes.

Leveling the curve of Spee is a commonly-used strategy to correct deep bites. Although several techniques have been proposed to intrude mandibular incisors (MI), flaring of these teeth is often observed and in many instances undesired. A three-dimensional (3D) finite element model (FEM) was used to locate the ideal point of force application (PFA) to achieve pure MI intrusion with the three-piece arches' technique. It comprised (1) a 0.021 × 0.025 in. stainless steel (SS) wire that passively filled the slots of the canine and premolar brackets and the first and second molar tubes, bilaterally; (2) a 0.0215 × 0.0275 in. SS intrusion base arch (IBA) inserted into the MI brackets, that presented a step down distal to the lateral incisors brackets and a posterior extension arm; (3) titanium-molybdenum tip-back springs designed to apply the intrusion force, fitted inside the first molar gingival tube. Four PFA on the IBA were simulated (FEM 1, 2, 3, and 4). FEM 3 resulted in pure MI and was considered the ideal PFA. FEM1 and 2 showed intrusion and buccal crown flaring of the MI, whereas FEM4 resulted in intrusion and lingual crown flaring of those teeth. Clinicians may consider three-piece arch mechanics to achieve pure MI intrusion. However, they must be aware that when force was applied anteriorly or posteriorly to the ideal PFA, the incisors would incline labially or lingually, respectively.
RESUMO
A geração de conhecimento obtida por meio da pesquisa científica materializa-se no anúncio dos resultados à sociedade. Este se faz basicamente de 2 formas: com apresentações em congressos e publicação de artigos científicos, ou por meio da solicitação de patentes. Se há intenção em auferir ganhos financeiros e materiais com as descobertas, ideias e inventos resultantes da pesquisa, a solicitação de uma patente se faz necessária. O objetivo deste artigo foi contribuir com a divulgação das informações pertinentes às patentes para o profissional da Odontologia brasileira. Uma descrição sucinta das etapas necessárias para a sua solicitação foi realizada. Deve-se reconhecer o esforço do Instituto Nacional de Propriedade Industrial (INPI) em disponibilizar no seu sítio eletrônico todas as informações necessárias aos interessados em fazer um pedido de patente, de maneira inteligível e didática, possibilitando a estes realizar seus próprios pedidos de patente de maneira autônoma.
The generation of knowledge obtained through scientific research materializes in the announcement of results to society. This is basically done in two ways: with presentations at congresses and publication of scientific articles, or through the application for patents. If there is an intention to make financial and material gains with the discoveries, ideas and inventions resulting from the research, the application for a patent is necessary. The aim of this article was to contribute to the dissemination of information pertinent to patents for the Brazilian Dentistry professional. A brief description of the steps required for its request has been made. It must be recognized the effort of the Instituto Nacional da Propriedade Industrial (INPI) to make available on its website all the information necessary to those interested in making a patent application, in an intelligible and didactic way, enabling them to make their own patent applications.
