激光去除腐质及充填治疗中的临床评价

The clinical evaluation of removal detritus and restorative treatment

目的:比较Er:YAG激光去腐的操作时间、患者疼痛指数、噪音指数以及树脂充填效果。方法:选取25例患者同时治疗2颗龋齿,分别采用Er:YAG激光去腐备洞技术(实验组)和常规涡轮牙钻、慢速手机去腐备洞技术(对照组)。记录操作时间、疼痛指数、噪音指数和术后6个月树脂充填情况。结果:实验组去腐时间长于对照组,实验组疼痛指数和噪音指数低于对照组,二组充填效果无显著差异。结论:Er:YAG激光是一种有效的去腐方法。

Objective The purpose of the present study is to compare operation time, pain scores, noise scores and the effect of resin filling in Er：YAG laser removal detritus. Methods Select 25 patients who have two caries to treat, respectively making use of Er：YAG laser （experimental group） and low- and high-speed handpieces （control group） to remove caries.Record operation time, pain scores, noise scores and the effect of resin filling after 6 month. Results The operation time of experimental group was longer than control group,but it was lower than control group in pain scores and noise scores.It is no point in comparing the effect of filling between two groups on the statistics. Conclusion Er： YAG lasers can remove caries effectively.
