Purpose: The aim of this in vitro study was to evaluate the influence of occlusal finish line configuration on microleakage of indirect composite inlays.
Materials And Methods: Forty-five recently extracted premolars were randomly assigned into three groups with different types of occlusal finish line preparations: bevel, chamfer, and butt joint. All restorations were made in Artglass (Heraeus Kulzer) and luted according to the manufacturer's recommendations.
