光固化树脂是当前修复龋齿的常用材料之一,但光固化树脂对牙髓具有一定的刺激性,如对龋病的适应症掌握不严,临床操作又不规范,光固化树脂修复体则可对牙髓造成损害,甚至可使牙髓坏死。本文采用羧酸锌粘固剂衬底后,应用光固化树脂对中龋修复治疗,其临床疗效的初步观察报道如下:材料与方法临床资料:从1997年6月～1998年5月,按龋病诊断标 Photocurable resin is one of the commonly used materials for the restoration of dental caries. However, the light-cured resin has some irritation to the dental pulp. For example, indications of caries are not strictly controlled and the clinical practice is not standardized. The photocurable resin restoration may be Damage to the pulp, and even pulp necrosis. In this paper, the use of zinc carboxylate cement substrate, the application of light-cured resin on the caries repair treatment, the preliminary observation of clinical efficacy reported as follows: Materials and Methods Clinical data: From June 1997 to May 1998, according to the caries Disease diagnosis mark
