ABSTRACT
A procura pela praticidade da clínica odontológica é cada vez maior. Em cimentações de peças protéticas com cimentos resinosos convencionais, a quantidade de passos faz com que haja um maior tempo clínico e demanda de habilidade do dentista, além de ser uma técnica sensível. Desta forma, foi desenvolvido um cimento universal, de passo único, cujo objetivo é eliminar passos e reduzir tempo clínico sem interferir nas propriedades que um cimento deve ter. Este trabalho teve como objetivo apresentar uma revisão de literatura para demonstrar o desempenho clínico e principais propriedades dos cimentos resinosos autoadesivos. Como conclusão, os cimentos autoadesivos têm apresentado bons resultados, porém é necessário que haja mais estudos clínicos longitudinais que comprovem sua eficiência.
The demand for convenience of dental practice is increasing. In prosthetic cementations with conventional resin cements, the number of steps implicates onlonger clinical time; demands proper skills of the dentist, and is a sensitive technique. Thusa new single step cement was developed, aiming to eliminate steps and reduce clinical time without interfering with the properties that a cement should have. The aim of this study was to present a literature review to demonstrate the main properties and clinical performance of self-adhesive resin cements. In conclusion, self-adhesive cements have presented good results, but further longitudinal clinical studies proving its effectiveness are still required.

The aim of this work was to present a small cross-sectional survey of composite restoration clinical attributes associated with choices for replacement. Ninety-four composite fillings selected to be replaced were included in this study. A questionnaire was filled out after each procedure in order to assess the clinical conditions that indicated the restoration replacement (marginal staining, unsatisfactory restoration anatomy, marginal fracture, fractured restoration body, painful symptoms, dental fracture, composite discoloration and/or restoration displacement). These conditions could be combined. The chi-square and Exact Fisher tests were performed to analyze the different variables (p < 0.05). The results showed that composite shade discoloration was the main cause of restoration replacement (63.8%). Marginal staining (50%), unsatisfactory restoration anatomy (50%), marginal fracture (14.9%), painful symptoms (8.5%), fractured restoration body (4.3%), dental fracture (1.1%) and total displacement of the restoration (1.1%) were conditions that could be associated. The main cause of dental composite restoration replacement was material shade mismatch with the dental structure (anterior teeth) or marginal staining and unsatisfactory restoration shape (posterior teeth). Marginal staining and composite shade discoloration contrasting with dental structure were related to the presence of caries.
