Abstract

This study evaluated the sealing of composite resin restorations after cavity preparation with high speed diamonds burs or Er:YAG laser. Two different adhesive systems were used; conventional and self-etching. Seventy bovine incisors were divided into groups according to the cavity treatment (N = 10): G1 (bur + acid + Excite); G2 (bur + One Up); G3 (bur + laser + Excite); G3 (bur + laser + One Up); G4 (laser + acid + Excite); G5 (laser + One Up) and G6 (laser + Excite). Restorations were performed with Filtek Z250 3M/ESPE. The specimes were then thermocycled and placed in a vacuum machine, at a negative atmosphere of 20 inch Hg for 5 minutes, for removal of entrapped air. This procedure was followed by immersion in a 50% silver nitrate solution. The teeth were sectioned and the evaluation of the marginal leakage was performed in a light stereomicroscope. The results were submitted to the ANOVA and Tukey statistical tests. It was concluded that preparations performed with high-speed turbines and Er:YAG laser presented the same performance; preparations with Er:YAG laser submitted to acid-etching and conventional adhesive system presented high values of marginal leakage, with statistical significance; conventional and self-etching adhesive systems presented the same performance as to marginal microleakage.
