掺钕钇铝石榴石激光治疗牙本质过敏症262例

Dentine hypersensitivity treated with Nd:YAG laser: experience with 262 cases

目的观察脉冲掺钕钇铝石榴石(Nd:YAd)激光治疗牙本质过敏的疗效。方法将牙本质过敏患牙262颗分为2组,实验组(n=131)采用脉冲Nd:YAG激光照射治疗,对照组(n=131)采用氟化钠治疗,分析比较两组疗效。结果实验组的即刻、1个月后、6个月后的有效率均高于对照组,两者有显著差异(P<0.01)。结论脉冲Nd:YAG激光治疗牙本质过敏是一种安全、高效的方法。

Objective To observe the curative effect of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser pulse in treating dentine hypersensitivity. Method A total of 262 teeth with dentine hypersensitivity were divided equally into 2 groups, namely the test group which received treatment with pulse Nd: YAG laser and the control group treated with sodium fluoride. Results The instant, 1-month and 6-month effectiveness in the test group was better than that in the control group, showing significant difference between the two groups (P<0.01). Conclusion Nd: YAG laser is safe and highly effective in treating dentine hypersensitivity.
