氟保护剂和极固宁TM对活髓基牙预备后牙本质过敏症的防治效果

目的评价氟保护剂和极固宁TM对烤瓷冠桥活髓基牙预备后牙本质过敏症的防治效果.方法对118例246颗活髓基牙预备后,随机分为3组,即氟保护剂组(实验Ⅰ组)、极固宁TM组(实验Ⅱ组)和临时冠组(对照组),分别用氟保护剂+临时冠、极固宁TM+临时冠和临时冠处理,观察其处理后的脱敏效果.采用F检验进行统计学分析(DPS数据处理系统V6.01).结果脱敏后1周,烤瓷冠桥黏固时和1个月后的疗效,实验Ⅰ、Ⅱ组与对照组均有着显著性差异(P＜0.05);而实验Ⅰ组和实验Ⅱ组均无显著性差异(P＞0.05).结论氟保护剂和极固宁TM对预防烤瓷冠桥活髓基牙预备后牙本质过敏有着较为理想的疗效,其操作简单,值得推广应用.

Clinical study of the effect of preventing dentine hypersensitiveness by using Fluor Protector and Green OrTM on the prepared vital pulp abutment teeth

PURPOSE: To study and evaluate the effect preventing dentine hypersensitiveness by using Fluor Protector or Green OrTM on the prepared vital pulp abutment teeth of PFM bridges. METHODS: 118 cases,246 prepared vital pulp abutment teeth, were randomly divided into three groups: Experimental Group A-treated with the Fluor Protector and temporary crown; Experimental Group B-treated with the Green OrTM and temporary crown, and Control Group-only using temporary crown. The results of desensitization in 3 groups were evaluated. F test was used for analysis (DSPV6.01). RESULTS: Significant differences were found between experimental Group A, B and the control group after 1 week(when cementing the PFM bridges); and also after 1 month (P<0.05). But no significant difference was found between experimental Group A and B(P>0.05). CONCLUSIONS: The effect of preventing dental hypersensitiveness by using Fluor Protector or Green OrTM on the prepared vital pulp abutment teeth of PFM bridges is ideal. It is easy to use and worth being widely applied.
