Abstract
Four different finishing techniques were used in a dentin bonding agent/composite resin restoration to evaluate the possible influence of finishing technique on microleakage. Results indicated that finishing technique affects the ability of the restorative system to resist microleakage. Under the conditions of this study, best results were achieved with a 30-fluted bur followed by a short wet polish. Samples finished dry with polishing disks demonstrated considerable microleakage. This study also suggests that homogeneous nonagglomerated microfilled composite resin does not require disk finishing.
