乙酸锶,氢氧化钙和氟化钠治疗牙本质敏感症临床疗效分析

The clinical curative effects comparison among three different chemical compositions for the treatment of dentin hypersensitivity

目的：比较10%乙酸锶,50%氢氧化钙和75%氟化钠治疗牙本质敏感的临床疗效。方法：选取2013年1-12月就诊于长沙市口腔医院牙体牙髓科的左上颌第一前磨牙牙本质敏感症的180名患者,随机分成3组,分别使用10%乙酸锶、50%氢氧化钙和75%氟化钠甘油进行脱敏治疗,观察治疗后1、3、6个月的疗效。结果：10%乙酸锶组脱敏效果明显优于50%氢氧化钙组和75%氟化钠甘油组,结果具有统计学意义（P〈0.01）。结论：10%乙酸锶治疗牙本质敏感有良好的治疗效果,可以作为牙脱敏治疗优先选择药物。

Objective： The clinical effect of the three different treatments for dentine hypersensitivity were compared among 10 % acetic strontium, 50 % calcium hydroxide and 75 % sodium fluoride. Method： The patients who had been to the Changsha stomatological hospital in the time from the January to the December in 2013 were chosen and the left first maxillary premolar which has dentine hypersensitivity syndrome were chosen as studied subjects. One hundred and eighty patients were randomly divided into three groups, 10 % strontium acetate, 50 % calcium hydroxide and 75 % sodium fluoride glycerine were used respectively for desensitization treatment in each groups. The curative effect were observed after 1 month, 3 months and 6 months. Result： The therapeutic effect of 10 % strontium acetate group is obviously better than the effect of 50 % calcium hydroxide group and 75 % sodium fluoride glycerine group, the results are statistically significant （P 〈0.01）. Conclusion： 10 % strontium acetate has good effect in the treatment of dentine hypersensitivity, which can be used as a preferred drug for dentin desensitization.
