SEM and microleakage evaluation of the marginal integrity of two types of class V restorations with or without the use of a light-curable coating material and of polishing.

Abstract

OBJECTIVES To evaluate the marginal integrity of class V restorations through an SEM observation and a microleakage test. METHODS Teeth with class V cavities were restored with either a flowable composite (n=20) or a glass ionomer cement (GIC) (n=20). Ten restorations in each group were immediately polished. A coating agent was applied on five polished… (More)
