Prime & Bood NT黏接剂及75%氟化钠甘油治疗牙本质过敏症的疗效对比观察

Clinical research of Prime & Bood NT bonding agents and 75% sodium fluoride glycerol for the treatment of dentine hypersensitivity

目的观察Prime&Bood NT黏接剂治疗牙本质过敏症的近期临床疗效,并探讨其作用机制。方法选择200例556颗牙本质过敏症患牙,随机分为实验组和对照组各278颗牙。实验组采用Prime&Bood NT黏接剂脱敏治疗,对照组采用75%氟化钠甘油脱敏治疗,并进行近期临床疗效对比观察。结果实验组治疗后即刻和3个月后的临床疗效均优于对照组(P<0.01)。结论 Prime&Bood NT黏接剂治疗牙本质过敏症近期临床疗效显著,值得临床推广应用。

Objective To observe the short-term clinical efficacy of the Prime&Bood NT bonding agents in&nbsp;the treatment of dentine hypersensitivity , and explore its mechanism.Methods Five hundred and fifty-six teeth from 200 patients with dentine hypersensitivity were randomly divided into the experimental group (278 teeth) and the com-parison group(278 teeth).The experimental group was treted with the Prime&Bood NT bonding agents;the compar-ison group was treated with 75% sodium fluoride glycerin desensitization agents , and the short-term clinical effects between two groups were compared .Results The clinical efficacy of the experimental group immediately after treat-ment and 3 months later was superior to that of control group (P<0.01).Conclusion The Prime&Bood NT bond-ing agents in the treatment of dentine hypersensitivity has significant short-term clinical efficacy,and is worthy of clini-cal application.
