Er:YAG激光与氟化钠治疗牙本质过敏症的疗效观察

Observation on the Clinical Effect of Er: YAG Laser Irradiation and Sodium Fluoride in Treating Dentin Hypersensitivity

目的:观察Er:YAG激光照射和氟化钠局部治疗牙本质过敏的临床疗效。方法:临床收集85名牙本质过敏的患者,随机分为A(激光治疗)、B(氟化钠治疗)、C(激光联合氟化钠治疗)和D(空白对照)4组,利用直观疼痛标尺法VAS(visual analogue scale)分析其疗效。结果:在观察期间实验组VAS评分均有降低的趋势,A、B、C和D组相比有统计学差异(P<0.05);C和A、B组相比有统计学差异(P<0.05)。结论:Er:YAG激光照射联合氟化钠局部治疗牙本质过敏临床疗效显著。

Objective： To observe the clinical curative effect of dentine hypersensitivity being locally treated by Er： YAG laser irradiation and sodium fluoride. Methods： 85 patients with dentine hypersensitivity were collected and randomly divided into four groups ：A （laser treatment）, B （sodium fluoride treatment）, C （combination treatment of laser and sodium fluoride） and D （blank controll）, following the VAS（visual analogue scale）score to analyze the clinical curative effect of different treatment on dentine hypersensitivity. Results： The VAS scores in observation period have a decreasing trend. Comparing A, B and C group with D group, there have statistical differences （P〈0. 05）. Comparing C group with A and B group, there have statistical differences （P〈0.05）. Conclusion： Combining with laser and sodium fluoride to treat dentine hypersensitivity locally has significantly clinical curative effect.
