1. Analysis of the marginal sealing of restorations after cavity preparation performed with laser Er,Cr:YSGG using different parameters in dentin / Análise do selamento marginal de restaurações realizadas após preparo cavitário com laser de Er;Cr:YSGG utilizando diferentes parâmetros em dentina hígida
The aim of this work was to evaluate dye penetration of Class V restorations in cavity preparations obtained with different power setting of an Er;Cr:YSGG laser or with diamond bur and high-speed handpiece. Sixty samples of dentin were divided into six groups (n=10). The first group served as a control with standardized diamond bur cut (G1); the other groups
