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.
V类洞预备体在体外使用牙本质粘结剂和复合树脂进行处理。对牙齿进行热循环、染色，并采用银染技术对边缘渗漏情况进行评分。仅使用复合树脂的对照组的渗漏明显多于经过牙本质粘结处理的实验组。对于这种牙本质粘结系统，用未填充的粘结树脂涂覆预处理的牙本质壁并无优势。
