Class V cavity preparations were treated in vitro with dentin bonding agents and composite. The teeth were thermally cycled, stained, and scored for marginal leakage, by a silver stain technique. The composite-only control group leaked significantly more than did the dentin-bonding-treated experimental groups. The coating of pre-treated dentinal walls with unfilled bonding resin offered no advantage with this dentin bonding system.
