口腔保健行为干预在牙周病治疗中的作用研究

目的：探讨口腔保健行为干预在牙周病治疗中的作用。方法：选择60例牙周病患者随机分为观察组和对照组各30例。对照组按自我口腔卫生保健模式，观察组由牙周科医师给予3个月1次的口腔保健行为干预，观察时间为1年。干预前后，采用牙周探诊深度（PD）、牙龈出血指数（BI）及复发率分别评定两组牙周病的治疗效果。结果：干预前，观察组与对照组PD和BI指数评分比较差异无统计学意义（P〉0．05）；干预后，观察组PD、BI指数和复发率均明显低于对照组，差异均有统计学意义（P〈0．01）。结论：实施口腔保健行为干预能够降低牙周病的复发，维持长久的治疗效果，具有积极的防治作用。
