Effect of different enamel preparation methods on microleakage of fissure sealant: An in vitro Study

ABSTRACT

Objective: Lack of a dental material with optimal adhesion and sealability is an important challenge in modern dentistry leading to marginal leakage. There are controversies on the necessity of enamel preparation in pit and fissure sealant therapy and its effect on decreasing the microleakage; therefore, the present in vitro study aimed to assess the amount of microleakage with and without enamel preparation
