All of the tested devices promoted dental changes, especially in the anterior region, and contributed to AOB reduction during the study period. However, fixed palatal crib demonstrated greater impact on the positioning of the incisors.

Objective: To evaluate the dimensional changes of dental arches on digital models of open bite treatment with fixed and removable palatal cribs. Materials and Methods: The sample comprised 41 patients of both sexes who were white, aged 7–10 years, and who had mixed dentition, Angle Class I molar relationship, and a negative overbite of at least 1 mm. The sample was randomly divided into two groups: G1, fixed palatal crib; and G2, removable palatal crib. Cast models, obtained initially (T1) and after 1 year of treatment (T2), were scanned by a three-dimensional (3D) scanner, 3Shape R700, producing a 3D image. Measurements were performed by a calibrated examiner using OrthoAnalyzer™ 3D software. Results: At T2–T1, differences were observed between the groups regarding vertical dentoalveolar development and overjet. There was more mandibular incisor extrusion for G1 (−1.66 mm) than for G2 (−0.54 mm). An overjet increase was observed in G1 (0.56 mm), in contrast to a reduction in G2 (−0.40 mm). There was a similar overbite increase for both groups (3.51 mm for fixed palatal crib and 3.88 mm for removable palatal crib). Conclusions: Both the treatment protocols are similarly effective for anterior open bite correction, providing an overbite increase with dentoalveolar arch changes, especially in the anterior region.

The method for individual assessment of midpalatal suture maturation revealed potential reliability and reproducibility. However, the agreement rate observed in the present study was not high enough for a method designed for routine clinical applications.

RESUMOEstudo transversal, exploratório e descritivo, de abordagem quantitativa, que teve como objetivo geral avaliar os efeitos da educação sexual relacionados ao HIV e a AIDS, entre adolescentes do Grupo AdoleScER -Saúde, Educação e Cidadania da região metropolitana de Recife -PE. Participaram 58 adolescentes do referido grupo, com idade entre os 10 aos 20 anos que responderam um questionário auto-respondido com 23 questões, entre outubro a dezembro de 2005, após parecer favorável da Comissão de Ética em Pesquisa do Hospital Agamenon Magalhães. Foram analisadas as variáveis idade, sexo, estado civil, religião, naturalidade, conhecimento sobre o HIV/AIDS, comportamentos sexuais, atitudes com relação aos portadores do HVI e com as práticas de sexo mais seguro, idade de início de atividade sexual e uso de preservativos. Para análise, os dados foram organizados, dispostos no programa Excel e submetidos à análise estatística-descritiva. Dentre os principais resultados, foi observado que 65,5% dos adolescentes eram do gênero feminino enquanto 34,5% do masculino; a grande maioria era de solteiros 98,28%; 1,72% estavam vivendo em união estável; 5,0% dos adolescentes do gênero masculino e 2,6% das adolescentes opinaram que se relacionavam principalmente com homens, mas também com mulheres; 39,7% já tiveram contato pênis/vulva, porém sem haver penetração vaginal. Dentre as práticas sexuais com penetração, a vaginal foi a mais citada 37,03%; 14,3% da amostra iniciou a vida sexual aos nove anos mantendo relação sexual anal; 9,9% aos 12 anos, a relação vaginal e 20,0% a relação oro-vaginal. Portanto, é fundamental que os profissionais da área de saúde, na abordagem da sexualidade humana, com os adolescentes, tenham sempre presente que os cuidados de saúde sexual devem visar ao enriquecimento da existência e das relações interpessoais, não se limitando a dar conselhos em matéria de procriação ou de tratar doenças transmitidas sexualmente. ABSTRACTCross-sectional, exploratory and descriptive study, in a quantitative approach that had as main objective to evaluate the sexual education effect related to the HIV and the AIDS, among adolescents of the Grupo AdoleScER -Saúde, Educação e Cidadania of the Recife -PE metropolitan region. 58 adolescents had participated, with age from 10 to 20 years old that had answered a questionnaire self-answered with 23 questions, from October to December 2005, after the project research has been approval for the Ethics Committee in Research of the Agamenon Magalhães Hospital. Variables Age, sex, status civil, religion, naturalness, knowledge on the HIV/AIDS, sexual behaviors, attitudes with regard to the carriers of the HVI and with the practical ones of safer sex had been analyzed, age of beginning of sexual activity and use of condoms. For analysis, the data had been organized, it was used the Excel program and submitted to statistics-descriptive analysis. Amongst the main results, it was observed that 65,5% of the adolescents were of the feminine gender while 34,5% of the masculine; the great ...
