There are few instruments available in Brazil for obtaining data on dental erosion among adults. For this reason, the interview entitled “A Survey on Hong Kong People’s Dietary Behavior in Relations to Acid Erosion”, published in English, was considered for translation. The aim of this study was to perform a cross-cultural adaptation and content validation for the Brazilian population. After obtaining the author’s permission, the interview underwent several stages: translation, back translation, review by a bilingual person and a committee of experts, administration of the English instrument and of the Portuguese version to a bilingual group, and pretesting in a convenience sample of 50 adults. The interview was translated and adapted to the Portuguese language and the Brazilian culture. The analysis of the data revealed that the interview was easy to apply, conduct and understand; therefore, it was considered viable and capable of being used in different studies.

OBJETIVO: o objetivo desse estudo foi verificar a associação entre volume gengival (AG) com condições periodontais e características sócio-demográficas em sujeitos com aparelho ortodônticos fixo. MÉTODOS: uma amostra, de 330 participantes com aparelho ortodôntico fixo, por pelo menos seis meses, foi examinada, por um único examinador calibrado, para os índices de placa e gengivais, profundidade de sondagem, nível de inserção clínico e aumento de volume gengival. O status socioeconômico, tempo com aparelho ortodôntico fixo e uso de fio dental foram verificados por entrevista oral. A verificação das associações foi realizada por meio de modelos de regressão de Poisson sem ajuste e ajustados. RESULTADOS: a presença de sangramento gengival (RR 1.01; 95% IC 1.00-1.01) e o excesso de resina em torno dos braquetes (RR 1.02; 95% IC 1.02-1.03) foram associadas a um aumento do AG. Não foram encontradas associações entre características sócio-demográficas e AG. CONCLUSÃO: sangramento gengival proximal na região anterior e excesso de resina no entorno dos braquetes estão associados a níveis mais altos de aumento de volume gengival na região anterior em sujeitos com aparelho ortodôntico fixo.

OBJECTIVE: The aim of this study was to investigate the association among gingival enlargement (GE), periodontal conditions and socio-demographic characteristics in subjects undergoing fixed orthodontic treatment. METHODS: A sample of 330 patients undergoing fixed orthodontic treatment for at least 6 months were examined by a single calibrated examiner for plaque and gingival indexes, probing pocket depth, clinical attachment loss and gingival enlargement. Socio-economic background, orthodontic treatment duration and use of dental floss were assessed by oral interviews. Associations were assessed by means of unadjusted and adjusted Poisson's regression models. RESULTS: The presence of gingival bleeding (RR 1.01; 95% CI 1.00-1.01) and excess resin around brackets (RR 1.02; 95% CI 1.02-1.03) were associated with an increase in GE. No associations were found between socio-demographic characteristics and GE. CONCLUSION: Proximal anterior gingival bleeding and excess resin around brackets are associated with higher levels of anterior gingival enlargement in subjects under orthodontic treatment.

Revisões sistemáticas prévias tem demonstrado melhores resultados com proteínas derivadas da matriz de esmalte (PDME) em comparação a retalho de espessura total (RET) para o manejo de defeitos periodontais infraósseos (DPI). O objetivo desse estudo foi determinar se essas diferenças variam de acordo com o tempo de acompanhamento e com a qualidade dos estudos. As bases de dados Cochrane Central Register of Controlled Trials, MEDLINE (PubMed), Lilacs, Embase e Web of Science foram pesquisadas sem limitação de tempo ate agosto de 2013 para ensaios clínicos randomizados. Os desfechos elegíveis foram alterações na profundidade de sondagem (PS), nível de inserção clinica (NIC), recessão gengival (RG) e alterações ósseas (AO). Resultados: Estudos com acompanhamento de ate 12 meses mostraram diferenças de 0.97 mm (CI95% 0.52 – 1.43) e 1.19 mm (CI95% 0.77 – 1.60) para PS e NIC, favoráveis a PDME, respectivamente. Estudos com acompanhamento ≥24 meses demonstraram vantagens de 1.11 mm (CI95% 0.74 -1.48) para NIC e 0.83 mm (CI95% 0.19 -1.48) para PS, com o uso de PDME. Considerando a qualidade dos estudos, publicações com baixo risco de viés exibiram menores diferenças entre os grupos apresentando 0.8 mm (CI95% 0.24-1.36) para o NIC, sem diferenças para PS (0.51 mm, CI95% -0.21 – 1.23). Pode-se concluir que o tempo de acompanhamento (< ou > 2anos) e o risco de viés são variáveis que influenciam nos resultados do tratamento com PDME em DPIO.

Previous systematic reviews have demonstrated better results with enamel matrix derivative proteins (EMDP) as compared with open flap debridement (OFD) for the management of infrabony periodontal defects (IPD). The aim of this study was to determine whether these differences vary according to the follow-up and quality of the studies. Cochrane Central Register of Controlled Trials, Medline/PubMed, Lilacs, Embase and Web of Science electronic databases were searched up to August 2013 for randomized clinical trials.Eligible outcomes were changes in probing depth (PD), clinical attachment level (CAL),gingival recession (GR) and bone changes (BC). Studies with follow-up of 12 months showed differences of 0.97 mm (CI95% 0.52 - 1.43) and 1.19 mm (CI95% 0.77 - 1.60) for PD and CAL, respectively, favorable for EMDP. Studies with follow-up ≥ 24 months presented advantages of 1.11 mm (CI95% 0.74 -1.48) for CAL and 0.83 mm (CI95% 0.19 -1.48) for PD,with use of EMDP. Considering the quality of studies, those with low risk of bias showed lower difference between groups, presenting 0.8 mm (CI95% 0.24-1.36) for CAL, favorable for EMDP and without differences for PS (0.51 mm, CI95% -0.21 - 1.23). In conclusion, follow-up time (< or > 2 years) and the risk of bias influence the results of treatment with EMDP in IPD.
