云南花腰傣妇女染齿行为与患龋情况关系的调查

Correlation between teeth staining and dental caries of the female Huayaodais in Yunnan Province

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。

Objective To explore the correlation between teeth staining and dental caries of the female huayaodais in Yunnan Province.Methods There were 303 female Huayaodais in Yunnan Province received an oral health survey,which was conducted according to the survey criteria of the Third National Oral Health Investigation in China,and a questionnaire was used to investigate the correlation between dental caries and lifestyles.Results The average DMFTs in the stained and unstained group were 4.74±3.77 and 5.97±5.10,and the differences was statistical significant;the dental caries prevalence were 90.6% and 91.2%,the OR was 0.93,and the 95% confidence interval was 0.34-2.30,no statistical significance was observed between the two groups with a chi-square examination（χ2=0.03,P=0.86）.The correlation between the dental caries and lifestyles showed no statistical significance（P0.05）.Conclusion The female Huayaodais with stained teeth had a lower DMFT than that of the unstained.Both of the two groups have relatively high caries prevalence,and their difference showed no statistical significance.Teeth staining did not protect the teeth from dental caries.
