摘　　要：目的观察不同脱敏剂治疗牙颈部牙本质敏感症的临床疗效。方法 76例牙颈部牙本质敏感症患者共214颗患牙根据敏感程度分为中等症状组(n=110)和重症组(n=104),分别采用Clinpro TMXT Varnish、Gluma脱敏剂和75%氟化钠甘油糊剂进行脱敏治疗,观察治疗后即刻的脱敏效果,并于治疗后1、3、6个月时复查,计算治疗有效率。结果治疗后即刻及1、3、6个月复查时,三种脱敏剂的治疗有效率在中等症状组与重症组间比较,差异均无统计学意义(P>0.05)。组内比较结果显示:Clinpro TMXT Varnish和Gluma脱敏剂的治疗后即刻疗效优于氟化钠甘油(P<0.05)。随着时间的延长,三组疗效均有下降,治疗后6个月时,Clinpro TMXT Varnish的治疗有效率高于Gluma脱敏剂和75%氟化钠甘油糊剂(P<0.05)。结论三种脱敏剂均可缓解牙颈部牙本质敏感症状,Clinpro TMXT Varnish有较好的远期疗效。Objective To observe the clinical effects of different desensitizers on cervical dentin hypersensitivity. Methods Seventy-six patients （214 teeth） with cervical dentin hypersensitivity were divided into moderate symptom group （n = 110） and severe symptom group （n = 104） according to the severity of hypersensitivity. Desensitization was randomly performed with Clinpro TMXT Varnish, Gluma and 75% sodium fluoride glycerol in each group. The efficacy was evaluated immediately after treatment and 1 month, 3 months and 6 months after treatment, and the effective rates were calculated. Results There was no significant difference in the effective rates immediately after treatment and 1 month, 3 months and 6 months after treatment between moderate symptom group and severe symptom group （P 〉 0.05）. The efficacy of Clinpro ^TMXT Varnish and Gluma was better than that of sodium fluoride glycerol immediately after treatment within the same group （ P 〈 0.05）. The efficacy decreased with time for all the three desensitizers. Six months after treatment, the effective rate of Clinpro ^TMXT Varnish was higher than those of Gluma and 75% sodium fluoride glycerol （ P 〈 0.05）. Conclusion All the three desensitizers may play a role in the treatment of cervical dentin hypersensitivity, and Clinpro ^TMXT Varnish may yield better long-term effects.
