Abstract
An important advance in restorative dentistry in recent years has been the indication that microleakage can be minimized around a composite resin with the use of acid etching and placement of an intermediary bonding agent on the walls of cavity preparations. Elimination or reduction of microleakage would result in a decrease in sensitivity, discoloration, and recurrent caries. Investigations have shown that microleakage is significantly reduced or eliminated in restorations where the enamel was etched and a layer of unfilled resin was placed before placement of the restorative material.
Some investigators recommended modification of classic preparation design for composite resins, such as butt joint/overlayed, beveled joint and curved bevel joint.
This study evaluated the marginal leakage of three commercially available composite resins in restorations prepared with different cavo surface design and modes of treatment.
