不同脱敏剂治疗牙本质过敏症的疗效观察

目的：评价不同脱敏药物对牙本质敏感症的治疗效果。方法：将180颗牙本质过敏症的牙齿随机分成3组，分别采用极固宁^TM，75％氟化钠甘油和氨硝酸银溶液进行脱敏治疗，进行近、远期有效率比较。结果：极固宁^TM、75％氟化钠甘油组间近期有效率差异无显著性，氨硝酸银溶液组与前2组差异有显著性；极固宁^TM远期有效率优于其它两组。结论：极固宁^TM治疗牙齿敏感症临床使用效果较好，副作用小，是目前理想的脱敏剂。

Comparative study of three desensitizers in their clinical desensitizing effect

Objective: This study is to compare the clinical effect of three different desensitive regents: Green OrTM,NaF and Ag(NO3)2NH4. Methods:180 patients attending our dental department were randomly divided into three groups. Each group was treated by Green OrTM,NaF or Ag(NO3)2NH4 respectively to compare their desensitizing effect after 1 month, six months period of observation. Results:The desensitive effect of three methods were significantly different. Superior desensitive results were observed in Green OrTM treatment group followed by NaF and Ag(NO3)2NH4 treatment group. Conclusion: The results suggest that all the three desensitizers have certain desensitive effect clinically, the Green OrTM has a better prolonged effect than NaF and Ag(NO3)2NH4 and suggest to be used clinically.
