本文采用粘结修复术修复前牙龋洞815颗。根据洪法廉教授提出的牙本质二层龋概念．作为去除龋坏的标准。操作时不制备洞型，去净崩坏层，保留软比层，进行临床疗效观察。采用材料为德国古莎与上海一拜耳齿科的酸蚀剂、釉质粘结剂、复合树脂。在前牙龋洞修复时若存在冷热激发痛明显者，使用氢氧化钙垫底，本组垫底50颗。分别于充填修复后3月、6月、1年观察结果。修复后一年成功780颗，失败35颗，成功率95．7％。从临床学上可说明：①前牙修复允许保留无基釉，操作时不制备洞型是可行的；②前牙粘结修复术去净外层龋，软化层可以保留；③酸蚀对牙髓组织不会造成损害；④减少细菌微渗漏的发生，可以减少继发龋的发生而提高修复术的成功率；⑤氢氧化钙在粘结修复中不是唯一刺激牙本质形成的因素。
In this paper, the use of adhesive repair anterior dental caries hole 815. According to Professor Hongfa Lian dental caries concept of two-story caries. As a standard to remove caries. The operation does not prepare the hole type, to net collapse of the layer, to retain the soft ratio layer, for clinical efficacy observation. Material used for the German Gusha and Shanghai Bayer Dental denture, enamel binder, composite resin. In the anterior teeth cavity repair if there is a hot and cold pain is obvious, the use of calcium hydroxide at the end of this group at the end of 50. Respectively in the filling repair after 3 months, 6 months, 1 year observation results. After the success of repair 780, failed 35, the success rate of 95.7%. From the clinical point of view can be described: ① anterior teeth to allow the retention of non-base glaze retained, the operation does not prepare the hole is feasible; ② anterior tooth adhesion repair net outer caries, softening layer can be retained; ③ acid etching teeth Pulp tissue will not cause damage; ④ reduce the incidence of bacterial micro-leakage can reduce the incidence of secondary caries and improve the success rate of repair; ⑤ calcium hydroxide in the adhesive repair is not the only factor to stimulate dentin formation.
