目的比较多功能纳米黏结剂Prime&bond NT与氟化钠甘油治疗牙本质过敏的临床疗效。方法选择2009年1月至2012年1月沈阳皇姑仁和口腔门诊部就诊的牙本质过敏患者96例(患牙186颗),随机分为试验组和对照组,试验组用多功能纳米黏结剂脱敏,对照组用氟化钠甘油脱敏,分别在治疗后即刻、3个月对脱敏效果进行观察分析。结果试验组在治疗后即刻、3个月的有效率分别为97.84%(91/93)、94.62%(88/93),而对照组则分别为70.97%(66/93)、66.67%(62/93);两组间相同时间观察结果比较,差异均有统计学意义(χ2=25.53、23.28,均P<0.01)。结论多功能纳米黏结剂Prime&bond NT治疗牙本质过敏临床疗效良好。
Objective To compare the clinical efficacy of multifunctional nanocomposite Prime & bond NT and sodium fluoride glycerol in the treatment of dentin hypersensitivity. Methods 96 cases of dentine hypersensitivity patients (186 teeth) were treated in Shenyang Huanggu Renhe Oral Clinic from January 2009 to January 2012 and were randomly divided into experimental group and control group. The experimental group was treated with multifunctional nano-cement Desensitization, the control group with sodium fluoride glycerol desensitization, respectively, immediately after treatment, 3 months to observe and analyze the desensitization effect. Results The effective rates of the experimental group were 97.84% (91/93) and 94.62% (88/93) respectively immediately after treatment, while those in the control group were 70.97% (66/93) and 66.67% / 93). The difference between the two groups was statistically significant at the same time (χ2 = 25.53, 23.28, all P <0.01). Conclusion The multifunctional nano-adhesive Prime & bond NT has good clinical efficacy in treating dentin hypersensitivity.
