脉冲Nd:YAG激光辅助极固宁脱敏剂治疗老年牙本质过敏症的临床研究

Observation of clinical effects on treating tooth hypersensitivity by pulsed Nd:YAG laser and Green^(TM) Or

目的:研究脉冲Nd:YAG激光辅助极固宁脱敏剂治疗老年牙本质过敏症的临床效果。方法:实验组用脉冲Nd:YAG激光1W(30mJ/cm2、15Hz)照射120sec后,涂擦极固宁脱敏剂3次;对照组只采用极固宁脱敏剂3次。结果:实验组即刻、3个月及6个月有效率分别为87.29%、81.36%和75.42%,对照组的有效率为79.09%、63.64%和52.73%。即刻两组差异无显著性(P>0.05),而3个月、6个月差异有显著性(P<0.01)。结论:脉冲Nd:YAG激光辅助极固宁脱敏剂治疗老年牙本质过敏症是一种高效、作用持久、使用安全的方法。

Objective： To evaluate the clinical effects on treating tooth hypersensitivity by pulsed Nd： YAG laser and GreenTM Or. Methods： Patients with tooth hypersensitivity were treated pulsed Nd： YAG laser with energy parameter of 1W （30mJ/cm^2,15Hz, 120sec）and desensitized with GreenTM Or for 3 times.GreenTM Or served as control group.Evaluation was carried out by statistical analysis immediately, 3 months and 6 months after treatment. Results： There was no obvious difference immediately after treatment （P〉0.05）. Clinical effects between the two groups were significantly different 3 months and 6 months after treatment （P〈0.01）. Conclusion： Pulsed Nd： YAG laser combined with GreenTM Or showed better clinical effects.It should be an widespread method in treating dentine hypersensitivity in the elderly,
