【摘要】 目的调查云南花腰傣妇女染齿行为与患龋情况的关系。方法按第三次全国口腔健康流行病学调查要求,对303名云南花腰傣妇女的患龋状况进行调查,其中染齿组212名,未染齿组91名。用格式化问卷调查龋齿与生活方式等因素的关系。结果染齿组和未染齿组的龋均分别为4.74±3.77、5.97±5.10,两组差异有统计学意义(t=2.33,P=0.01);染齿组和未染齿组患龋率分别为90.57%、91.21%,危险度比值比为0.93,95%可信区间为0.34～2.30,两组患龋率差异没有统计学意义(χ2=0.03,P=0.86);受调查者的生活方式与患龋情况的相关性无统计学意义(P>0.05)。结论没有证据显示花腰傣妇女染齿具有降低患龋率的作用,但染齿者龋齿程度较轻。更多还原
