Previous issue date: 2014-03-28 / The aim of this study was to clinically evaluate the performance of indirect composite resin restorations cemented with conventional and self-adhesive resin cement, during a 12-month period. Twenty-four composite resin restorations were performed through indirect technique and cemented with two resin cements: a conventional (RelyX ARC) and a self-adhesive (RelyX U100). Two independent evaluators analyzed the restorations using the criteria of the USPHS (United States Public Health Service) modified after two weeks, six months and 12 months. For the analysis of data from USPHS, between the cements at the same time, it was used the Wilcoxon statistical test and for evaluation at different times, it was used the Mann-Whiney test, at significance level of 5 %. The Fisher exact test was used to assess the occurrence of absolute failures. No statistically significant differences were found between groups in the same period and between groups at different times, one statistical difference was found only for the criteria color match. We conclude that indirect composite resin restorations cemented with self-adhesive resin cement showed a similar performance of restorations cemented with conventional resin cement after a year of analysis. / O objetivo deste estudo foi avaliar clinicamente o desempenho de restaura??es indiretas de resina composta cimentadas com cimento resinoso convencional e autoadesivo no per?odo de 12 meses. Foram realizadas 24 restaura??es em resina composta (Filtek Supreme XT), executadas pela t?cnica indireta e cimentadas com dois cimentos resinosos: um convencional (RelyX ARC) e um autoadesivo (RelyX U100). Dois avaliadores independentes analisaram as restaura??es atrav?s dos crit?rios do USPHS (United States Public Health Service) modificado ap?s duas semanas, seis meses e 12 meses. Para a an?lise dos dados do USPHS, entre os cimentos no mesmo tempo, foi utilizado o teste estat?stico de Wilcoxon e, para avalia??o nos diferentes tempos, o Mann-Whiney ao n?vel de signific?ncia de 5%. O teste exato de Fisher foi usado para avaliar a ocorr?ncia de falhas absolutas. N?o foram encontradas diferen?as estatisticamente significativas entre os grupos no mesmo per?odo e entre os grupos nos diferentes tempos, havendo diferen?a estat?stica apenas para o crit?rio combina??o de cor. Pode-se concluir que restaura??es de resina composta indireta cimentadas com cimento resinoso autoadesivo tiveram um desempenho similar ?s cimentadas com cimento resinoso convencional ap?s um ano de avalia??o.
