半导体激光治疗牙齿感觉过敏症的临床观察

The clinical observation of semi-conductor laser treatment of hypersensitive dentine

目的 :观察半导体激光治疗牙齿感觉过敏症的疗效。方法 :将 12 6例患者分为实验组和对照组。实验组 (14 2牙 )行激光治疗 3次 ;对照组 (138牙 )用 75 0ml/L氟化钠甘油局部涂擦 3次。结果 :实验组及对照组即刻总有效率分别为 95 .8%、75 .4 % ,但实验组在即刻和远期疗效方面明显优于对照组 (P <0 .0 1)。结论 :半导体激光是治疗牙齿感觉过敏症的一种安全、有效、方便的方法。

AIM: To observe the effects of treatment on hypersensitive dentine by semi-conductor laser. METHODS: 126 patients were divided into two groups, experimental group and control group. In the experimental group 142 teeth were dealt with semi-conductor laser three times. 138 teeth of the control group were dealt with 750ml/L sodium fluoride glycerine to rub at local zone three times. RESULTS: The immediated total effectiveness of the experimental group was 95.8%, which of control group was 75.4%. The immediate and long-time total effectivenesses of the experimental group were both prominently better than those of the control group ( P <0.01). CONCLUSION: Semi-conductor laser is a safe, effective and convenient method to treat hypersensitive dentine.
