一种新型树脂粘结剂安全性及有效性的临床评价

Clinical Assessment on the Safety and Efficiency of One Neo-type Resin Cement

目的:观察一种新型树脂粘结材料应用于活髓牙粘结时是否具有良好的安全性及粘结强度。方法:80名受试者随机分为2组,每组各40例,实验组采用NISSIN公司生产的新型牙科树脂基粘结剂,对照组采用3MESPE AG公司生产的通用自粘结树脂型粘结材料(Rely×100),每组病例在粘结完成后1周、3月、6月复查。评价指标包括:牙髓情况、口腔软组织有无过敏反应、修复体粘结情况。结果:80例受试者均未出现严重不良牙髓反应及口腔软组织过敏反应,74例临床反应等级属于无刺激。结论:该新型树脂基粘结剂应用于活髓牙的粘结修复是安全的、有效的。

Objective：To assess the safety and adhesive efficiency of one neo-type resin cement used as a vital teeth bonding agent.Methods：80 volunteers were divided into two groups randomly.The test group was applied with the neo-type resin cement made by NISSIN and the other one was applied with Rely×100 made by 3M ESPE AG.Every case was visited after one week,three months and six months.The evaluation index included postoperative tooth sensitivity,oral mucosal allergy and adhesive efficiency.Results：74 cases were not found tooth pulp sensitive,oral mucosal allergy and no crown dropping.Conclusion：The neo-type resin cement used as vital teeth adhesive was safe and efficient.
