Objetivo: realizar uma revisão sobre possíveis fatores de risco para RRAE em pacientes submetidos ao tratamento ortodôntico. Material e Métodos: a pesquisa foi realizada no banco de dados MEDLINE, através do PubMed, usando a ferramenta de busca avançada, onde foram inseridas as seguintes palavras-chave, escolhidos segundo o Descritores em Ciências da Saúde (DeCS): ortodontia, reabsorção radicular, incisivo e polimorfismo genético, associado aos operadores boleanos “E” e “OU”. A busca encontrou artigos de 1993 até 2016. Resultados: constatou-se que o tratamento ortodôntico é um fator de risco para RRAE, sendo os incisivos superiores os dentes mais acometidos. O sexo e a idade do paciente não parecem influenciar o grau de RRAE, assim como outros fatores clínicos e relacionados ao tratamento ortodôntico, com exceção do tempo de tratamento prolongado e aplicação de forças pesadas, que estão associados com maiores níveis de RRAE. Tratamento com extrações, uso de elásticos intermaxilares e diferentes polimorfismos genéticos apresentaram resultados conflitantes, não sendo possível definir a real relação com a RRAE. Diferenças metodológicas e populacionais entre os artigos avaliados podem explicar a divergência de resultados encontrada na literatura. Conclusão: apesar de diversos fatores intrínsecos, clínicos, genéticos e relacionados ao tratamento ortodôntico terem sido descritos na literatura, os mais frequentemente descritos como reais fatores de risco para RRAE são o tempo de tratamento ortodôntico prolongado e a aplicação de forças pesadas.

Objective: to perform a literature review on the denture stomatitis (DS) treatment, in order to propose the incorporation of chlorhexidine into the denture as a treatment strategy for DS. Material and Methods: an advanced search was undertaken in MEDLINE/PubMed baseline from 1976 to 2016. Sixty-five papers were retrieved using the following keywords: chlorhexidine, denture stomatitis, denture relining. Of those, 35 papers were directly related to the subject and were therefore selected for a narrative review. Results: DS is an inflammatory reaction of multifactorial etiology, usually associated with Candida albicans and often observed in complete denture wearers. Most treatments rely on patient cooperation. Chlorhexidine (CHX) has antifungal activity and can be incorporated into denture lining materials without causing significant alterations in denture resin structure and without depending on patient compliance. Conclusion: according to the results of in vitro studies, CHX released from denture relining materials may be convenient to reduce denture biofilms and treat DS, but further in vivo studies are necessary to recommend clinical use.

Overdentures retained by a combination of a clip bar and attachment presented better stability and retention capacity under our experimental conditions, close to that of the positive control (fixed complete denture), with the advantages of removable overdentures.

ObjectiveTo propose the development and validation of criteria for evaluating the clinical performance of indirect restorations, considering the variables related to the operator, material, and/or patient.Materials and MethodsThe experimental design of this study was divided into three stages. Stage 1: development of the new criteria items by specialists in Prosthodontics. Step 2: creation of the criteria, named UERJ criteria, with the description of the parameters that indicate the quality of the restoration, the possible associated complications, and a detailed description of each classification. As well as the development of a form of variables. Step 3: validation of the UERJ criteria.ResultsCohen's Kappa statistic registered for both intra‐ and inter‐examiner agreements a coefficient >0.91 with a p‐value <0.0001. The validity of the UERJ criteria was evaluated by tests of sensitivity (0.96) and specificity (0.91) and had a satisfactory accuracy (92.7%), a positive (10.99), and negative (0.05) likelihood ratio and high values predictive variables, with positive (PPV) 0.84 (high specificity) and negative (VPN) 0.98 (high sensitivity), with a confidence interval of 95%.ConclusionThe UERJ criteria is a valid instrument for evaluating the clinical performance of indirect restorations.Clinical SignificanceThe UERJ criteria, developed exclusively for the analysis of indirect restorations, elucidates the details necessary to identify the causes of failures and complications of these restorations.
