摘　　要：目的:对奥敏清牙齿脱敏剂联合Er:YAG激光治疗青少年牙本质敏感症的疗效进行研究。方法:78例(共163颗患牙)青少年牙本质敏感症患者随机分为奥敏清组(n=54)、激光组(n=55)和联合组(n=54),奥敏清组患者给予单一奥敏清牙齿脱敏剂涂布治疗,激光组患者给予单一的Er:YAG激光照射治疗,联合组患者在Er:YAG激光照射后再涂布奥敏清牙齿脱敏剂治疗,比较治疗前、治疗即刻和治疗后1周、1月、3月、6月VAS值、总有效率。另将20颗新鲜离体牙随机分为4组,分别用生理盐水、奥敏清牙齿脱敏剂、Er:YAG激光及奥敏清联合Er:YAG激光处理,扫描电镜观察各模型样本形态。结果:联合组在治疗即刻及治疗后各时间点的VAS值均显著低于奥敏清组和激光组(P<0.05);总有效率均显著高于奥敏清组和激光组(P<0.05);奥敏清组和激光组在治疗即刻、治疗后1周、1月、3月时的总有效率差异无统计学意义,但激光组在治疗后6月的总有效率却显著高于奥敏清组(P<0.05)。扫描电镜结果显示奥敏清、Er:YAG激光及奥敏清联合Er:YAG激光处理均可封闭牙本质小管,且奥敏清联合Er:YAG激光的封闭效果最佳。结论:奥敏清牙齿脱敏剂联合Er:YAG激光治疗青少年牙本质敏感症具有较好的临床效果。Objective：To study the clinical effect of Minqing Ao dental desensitizer combined with Er：YAG laser on the treatment of dentine hypersensitivity in teenagers.Methods：Seventy-eight cases（163teeth）of dentine hypersensitivity in teenagers were randomly divided into the Minqing Ao group（n=54）,the laser group（n=55）and the combined group（n=54）.The Minqing Ao group was treated with Minqing Ao dental desensitizer alone,the laser group was treated with Er：YAG laser irradiation,and the combined group was treated with Er：YAG laser irradiation combined with the later Minqing Ao dental desensitizer.The visual analog scale（VAS）and total effective rate of the Minqing Ao group,the laser group and the combined group were compared before,immediately after,and 1week,1,3,6months after treatment.Another 20 fresh teeth were selected and randomly divided into four groups.The dentin hypersensitivity model samples of four groups were treated by using normal saline,Minqing Ao dental desensitizer,Er：YAG laser,Minqing Ao dental desensitizer combined with Er：YAG laser respectively.Sample morphology of all 20 specimens was observed under scanning electron microscope.Results：The VAS of the combined group was significantly lower than that in the Minqing Ao group and in the laser group（P〈0.05）.Total effective rate of the combined group was significantly lower than that in the Minqing Ao group and the laser group immediately after and 1week,1,3,6months after treatment（P〈0.05）.Total effective rate of the Minqing Aogroup and the laser group immediate after and 1 week,1month,3 months after treatment showed no statistical significance.Conclusion：Minqing Ao dental desensitizer combined with Er：YAG laser in the treatment of dentine hypersensitivity in teenagers has better clinical effects.
