摘　　要：目的:应用掺铒铬钇钪镓石榴石(Er,Cr:YSGG)激光去腐备洞技术在减轻疼痛、充填后远期效果及工作效率等方面的临床评价。方法:选择口内同时存在2个龋坏程度相似的同名牙病例30例,自身对照方法,分别采用Er,Cr:YSGG激光(实验组)和传统涡轮牙钻(对照组)去腐备洞。使用Wong-Baker面部表情量表对治疗过程中的疼痛程度进行评估,调查每个病例对两种方法的接受程度,记录去腐备洞时间,并分别在治疗后6个月,12个月复查充填体情况。结果:和传统的涡轮牙钻去腐备洞比较,Er,Cr:YSGG激光可明显减轻备洞过程中的疼痛,差异有显著性(P<0.01);80%的患者更愿意选择Er,Cr:YSGG激光技术进行治疗;Er,Cr:YSGG激光和涡轮牙钻去腐备洞的平均时间分别是504s和390s;治疗后6个月,12个月复查,实验组和对照组差异无显著性。结论:Er,Cr:YSGG激光去腐备洞技术可显著减轻治疗过程中的疼痛和不适,在切割牙体硬组织方面具有独特的优点。Objective：To evaluate Er,Cr：YSGG laser system objectively through randomized control trial in clinic.Method：30 patient were selected randomly and the method of self-comparison was adopted.Each patient had at least two teeth of which caries degree were similar.Caries was removed and cavities were prepared using Er,Cr：YSGG laser（Biolase,USA） technique and traditional handpiece method respectively.Each patient were required to select which method he prefer through a questionnaire.The time of caries removal and cavity preparation was recorded. Patients were called back for checking restorations 6 months and 12 months after treatment. The pain degree of each patient was recorded with Wong- Baker Facial Pain Scale. Result：Average time of Er, Cr：YSGG laser and turbine method for were 504 s and 390s respectively. Er, Cr：YSGG laser can alleviate pain obviously compared with traditional method, the difference is significant （x2=21.99, P〈 0.01）. 80% patients prefer Er, Cr：YSGG laser to traditional method. There is no significant difference between two group restorations 6 months and 12 months after treatment. Conelusion：Er, Cr：YSGG laser can alleviate treatment pain and discomfort obviously, so it is a new and effective technology for dental hard tissue surgery.
