Dental Preparation with Sonic vs High-speed Finishing: Analysis of Microleakage in Bonded Veneer Restorations

Purpose: To compare marginal microleakage in porcelain veneer restorations following dental finishing using two
types of instruments to test the hypothesis that microleakage will be less when teeth are prepared with sonic
oscillating burs than when prepared with high-speed rotating burs.

Materials and Methods: Fifty-six extracted human maxillary central incisors were selected and divided randomly
into two groups. Group 1 samples underwent dental finishing using high-speed rotating diamond burs, while
