INTRODUÇÃO: A contaminação do substrato dentinário pode interferir na qualidade de união entre materiais adesivos e o dente. OBJETIVO: Investigar a influência de diferentes soluções de irrigação na resistência de união de um cimento resinoso. MATERIAL E MÉTODO: Foram selecionadas 40 coroas dentais bovinas, divididas em quatro grupos: G0 = soro; G1 = clorexidina; G2 = EDTA; G3 = clorexidina 0,12%, após condicion...
Direct composite resin restorations have become a viable alternative for patients that require anterior restorative procedures to be integrated to the other teeth that compose the smile, especially for presenting satisfactory esthetic results and minimum wear of the dental structure. Technological evolution along with a better understanding of the behavior of dental tissues to light incidence has allowed the de...
Dentin adhesion procedure presents limitations, especially regarding to lifetime stability of formed hybrid layer. Alternative procedures have been studied in order to improve adhesion to dentin. OBJECTIVE: The aim of this study was to evaluate in vitro the influence of deproteinization or dentin tubular occlusion, as well as the combination of both techniques, on microtensile bond strength (µTBS) and marginal ...
