摘要

Objectives: The purpose of this study was to compare microleakage of Class V restorations following acid, laser or laser and acid treatment of cavity walls. Methods: Standardized lingual and buccal Class V preparations were made in 18 human extracted third molars. The preparations were Randomly assigned to three equal groups (n=12).
