不同方法治疗牙齿敏感症的疗效分析

目的 :比较激光 ,激光加氟化钙和涂擦Gluma等 3种方法治疗牙齿敏感症的效果。方法 :按就诊顺序 ,随机选择 3组病例 ,分别采用激光、激光加氟化钙、涂擦Gluma进行牙齿敏感症的脱敏治疗。结果 :三种脱敏方法的即刻疗效比较无显著性差异 ,P >0 .0 5 ;一月后 ,Gluma组疗效低于另外两种方法组 ,有显著性差异 ,P <0 .0 5 ;随着观察期的延长 ,三种治疗方法的有效率逐渐降低 ,半年后 ,激光加氟化钙组的有效率为 67.9% ,激光组为 49.4% ,Gluma组为 2 3 .3 % ,差异有显著性 ,P <0 .0 1。结论 :三种方法治疗牙齿敏感症均有较好的即刻效果 ,远期疗效以激光组和激光加氟化钙组为优 ,激光氟化钙组半年后疗效仍为 67.9% ,显示了较好的应用前景。

The effects among three desensitive tooth methods

Objective:This study is aim to compare the effects among three desensitive tooth methods. Method:According to the sequency,patients were randomly divided into three groups.Each group was treated by Nd:YAG laser,Nd:YAG laser-with-CaF 2 or Gluma.Seven days later,Each method was replaced by another. Result: Immediate effects of three groups were significantly different(p<0.05).One month later,Gluma's effect was less than others(p<0.05).As the time went by,the effective rates of three groups fell gradually.Six months later,the effective rates of laser,laser-with-CaF 2 and Gluma were significantly rduced(67.9%,49.4% and 23.3% respectively, p<0.01). Conclusion: The immediate effect in every method is good,long-dated efficiency in laser and laser- with-CaF 2 groups are better than Gluma group,especially,laser- with-CaF2 group shows good prospect.
