摘　　要：目的研究半导体激光联合MS-COAT脱敏剂治疗牙本质过敏症的临床效果。方法将32例(共120颗患牙)牙本质过敏症患者随机分为2组,治疗组使用半导体激光500 mW(波长810 nm、频率50 Hz、光斑直径3mm)照射300 s后,局部涂擦MS-COAT 2次;对照组只采用MS-COAT脱敏剂涂擦2次。结果治疗组和对照组治疗后即刻效果满意,2组差异无显著性(90.0%vs 86.7%,P>0.05);1、3个月后2组疗效均开始下降,但对照组下降明显,2组疗效对比1个月有显著性差异(88.3%vs 76.7%,P<0.05),3个月有极显著性差异(85.0%vs65.0%,P<0.01)。结论半导体激光联合MS-COAT脱敏剂治疗牙本质过敏症是一种简便迅速、疗效持久、安全无痛的方法。Objective To study the clinical efficiency of dentin hypersensitivity treatment by semiconductor laser with MS-COAT. Methods A total of 120 teeth from 32 patients with dentin hypersensitivity were divided into two groups, and treated by two different methods. Treatment group patients were treated by semiconductor laser with energy parameter of 500 mW （wavelengh 810 nm, frequency 50 Hz, facula diameter 3mm） irradiation time 300 s and daubed with MS- COAT for 2 times. MS-COAT served as control group. Observed their clinical effects respectively. Results The effective of treatment and control groups,the moment were 90.0% and 86.7%, 1 month later were 88.3% and 76.7% ,3 month later were 85.0% and 65.0%. There was no statistic difference immediately after treatment（P〉0.05）, but there was significance 1 month later （P〈0.05） and 3 month later（P〈0. 01） after treatment. Conclusion Semiconductor laser with desensitizer MS-COAT is an effective and convenient technique for treating dentin hypersensitivity.
