Effect of Pre-heating Resin Composite on Restoration Microleakage

Abstract

Clinical Relevance The results of this study indicate that preheating composites can improve adaptation of resin composites to tooth structure. This technique significantly reduced microleakage. However, delaying light curing of the preheated composite after placement appears to be counterproductive and diminishes the positive effects from the preheating treatment. Flowable liner was less effective than preheating the composite in reducing microleakage.
