多乐氟预防可摘局部义齿基牙患龋的临床研究

目的 观察多乐氟对可摘局部义齿基牙的防龋效果. 方法 行可摘局部义齿修复的牙列缺损患者100例,采用自身对照的方法,患者修复义齿后,随机选择一侧基牙作为试验侧基牙组涂布多乐氟,半年重复1次,对照侧基牙组做空白对照,3年后复诊检查可摘局部义齿基牙的龋坏情况. 结果 试验侧基牙组患龋率为24. 7%(40/162),低于对照侧基牙组41. 9%(67/160),差异具有统计学意义(χ2 =10. 71,P<0. 01). 结论 可摘局部义齿基牙涂布多乐氟可有效预防龋病的发生.

Clinical research on the effect of Duraphat in the prevention of dental caries of abutment teeth in removable par-tial denture

Objective To investigate the effect of Duraphat in the prevention of dental caries of abutment teeth in re-movable partial denture. Methods 100 patients who suffered from dentition defect were recruited. We used self-control methods. Abutment teeth of one side were randomly assigned to control group, abutment teeth of another side were as-signed to experimental group. In experimental group, Duraphat was applied every six months. The prevalence of caries of abutment teeth of removable partial denture was recorded 3 years later. Results The data showed that the caries preva-lence of experimental side was significantly lower than the control side ( P<0. 01) . Conclusion It is a simple and effec-tive way to prevent caries in the abutment teeth of removable partial denture with Duraphat.
