1、低能量激光治疗老年人牙本质过敏症的临床探讨[摘要]目的:评价短时间低能量激光应用于治疗老年人牙本质过敏症的近期临床疗效,以及牙本质过敏症两种检查方法的可靠性。方法:27例牙本质过敏症患者共计54颗患牙分为两组:低能量激光治疗组(A组)27颗患牙、激光未开启组(B组)27颗患牙。采用数字化疼痛评判法VAS(VisualAnalogueScale)测量牙本质敏感程度。每组患者分以下几个阶段进行疗效评估,观察治疗前、治疗后(10min)、1周、2周、3周及4周的VAS值。采用单因素方差分析对结果进行统计学分析。结果:短时间低能量激光对老年人牙本质过敏症在不同的时间均有疗效(P
2、<0.05);牙本质过敏症检查方法中,冷刺激比探针刺激更可靠。结论:短时间低能量激光治疗老年人牙本质过敏症具有良好的效果。[关键词]分木质过敏症;低能量激光;VAS;老年人[中图分类号JR783[文献标识码]A[文章编号11008-6455(2014)07-0569-04ClinicalinvestigationoflowlevellaserirradiationonhypersensitivedentinoftheelderlyZHANGYi,ZHOUQian,LIUFan(DepartmentoftheOrthodontics,DalianStomatologica
