摘　　要：目的:观察脉冲Nd:YAG激光蚀刻牙硬组织后增加与复合树脂结合力的临床效果方法:观察组采用脉冲Nd:YAG激光照射窝洞后进行光固化治疗,对照组以常规酸处理后光固化治疗。结果:观察组115个牙齿成功105,有效6个,失败4个;对照组成功76,有效21,失败18个。两组间有非常显著性差异(P<0.01)。结论:脉冲Nd:YAG激光代替酸处理蚀剂牙硬组织进行光固化治疗上一种可行的方法。Objective To analyze the increased bond strength in clinic between photosensing resin with tooth, hard, tissue etch by the pulsed Nd： YAG laser. Methods All teeth were ray - solidified after observation group were processed with pulsed Nd： YAG laser and counter group were processed with phosphine - cauterization. Results 105 teeth were success and 6 teeth were invalid and 4 teeth were failed in all 115 teeth of observation group; 76 teeth were success and 21 teeth were invalid and 18 teeth were failed in all 115 teeth of counter group. Conclusion Substituted phosphine cauterization with pulsed Nd： YAG laser irritation is feasible mcasurement in etching tooth hard - tissue.
