目的:探讨左右手刷牙习惯及对应的个体化口腔卫生健康教育指导对青少年正畸患者口腔卫生的中短期影响。方法:选取2011年至2015年深圳市第二人民医院口腔科接受固定正畸治疗的患者460名,年龄11~14岁,通过问卷形式了解患者属于左手刷牙习惯或右手刷牙习惯,从中随机分配右手刷牙习惯患者50名到观察组A组,50名到对照组B组;随机分配左手刷牙习惯患者50名到观察组C组,50名到对照组D组。对A组和C组患者,除常规口腔卫生健康教育和指导外,还针对性进行左右手交替刷牙习惯的指导;对B组和D组患者,仅进行常规口腔卫生健康教育和指导。固定正畸治疗进行6个月后,分别记录4组患者的左侧和右侧软垢指数(DI)、牙石指数(CI)、菌斑指数(PLI)。结果:A组和C组患者左右侧DI、CI、PLI比较,差异均无统计学意义(P>0.05),B组和D组患者左右侧DI、CI、PLI比较,差异具有统计学意义(P<0.05)。结论:患者的左手、右手刷牙习惯的区别,对左、右侧口腔卫生的维护具有影响;在矫治过程中有针对性地施加个性化口腔卫生健康教育指导,有助于维护和促进青少年固定正畸患者的口腔卫生健康状况。
