Nd:YGA激光治疗牙本质过敏症的疗效观察

Clinical efficacy of Nd:YAG laser in the treatment of dentine hypersensitivity

目的:观察Nd:YGA激光治疗牙本质过敏症的治疗效果。方法:选取牙本质过敏症病人200例(380颗患牙),随机分为2组,每组100例。对照组(180颗患牙)采用Gluma脱敏剂冶疗,观察组(200颗患牙)采用Nd:YGA激光脱敏冶疗。比较2组病人治疗后即刻、1周、1个月、3个月、6个月、12个月的治疗效果。结果:2组病人脱敏治疗即刻、1周、1个月、3个月后疗效比较差异均无统计学意义(P>0.05),6个月和12个月比较差异有统计学意义(P<0.05)。结论:Nd:YGA激光治疗牙本质过敏症具有较好的中远期临床疗效。

Objective： To observe the clinical efficacy of Nd： YAG laser in the treatment of dentine hypersensitivity. Methods： A total of 200 patients with dentine hypersensitivity（ 380 ill teeth） were randomly divided into the control group and observation group（ 100 cases each group）. The observation group（ 200 ill teeth） were treated with Nd： YAG laser desensitization,and the control group（ 180 ill teeth） were treated with Gluma desensitizer. The clinical efficacy between two groups after 0 hour,1 week,1 month,3 months,6 month and 12 month of treatment were compared. Results： The differences of the effective rates between two groups after 0 hour,1 week,1 month and 3 months of treatment were not statistically significant（ P〉0. 05）,and the differences of the effective rates between two groups after 6 and 12 months of treatment were significant（ P〈0. 05）. Conclusions： The Nd： YAG laser in the treatment of dentine hypersensitivity has good middle and long-term clinical effects.
