摘　　要：目的了解西藏那曲地区藏族学生砖茶型氟牙症及龋病流行情况,并对两者关系进行探讨。方法2004年7月采用单纯随机抽样的方法,对12～17周岁的471名藏族学生,按WHO推荐的Dean分类法和龋病调查方法对氟牙症及龋病患病情况进行检查;采用SPSS11.5进行统计分析,氟牙症与龋病的相关性分析用Mantel-Haenszelχ2检验和线性相关性检验;将不同程度的氟牙症按Dean标准分级,并与龋病患龋率进行分层趋势χ2检验。结果氟牙症患病率为53.5%,氟牙症指数为1.09,属中度流行地区;恒牙患龋率较高(56.7%),程度较重(龋均为4.09±2.106);龋病的发生与氟牙症呈高度正相关(χM2H=12.060,P<0.01;OR=1.954,P<0.01),为显著线性关系(χ2=12.715,P<0.01);随着氟牙症程度的加重,患龋率呈上升趋势(χ2=14.846,P<0.01)。结论砖茶型氟牙症已成为当地龋病高发的易感因素;减少氟牙症的发生,应成为当地藏族学生预防龋病的重要措施之一。ObjectiveTo study correlation between dental fluorosis and dental caries among Tibetant students in Tibet Naqu.Methods471 Tibetant students were investigated.Simple random sampling was used to investigate dental fluorosis and dental caries among students between 12 and 17 years old.Dental fluorosis and dental caries were classified according to method of Dean and research on caries.SPSS 11.5 was used to analyze the data.Mantal-Haenszel χ2 test and Linear-by-linear Association test were used to study the correlation.The Trend χ2 test was used to analyze caries prevalence rate according to different level of dental fluorosis.ResultsThe caries prevalence rate of dental fluorosis was 53.5%.The index of dental fluorosis was 1.09.Dental fluorosis was middling prevalent in the region.There were high incidence of caries prevalence rate(56.7%)and serious(caries mean is 4.09±2.106)in permanet teeth.The incidence of dental caries was positively correlated to the quantity of dental fluorosis(χ2MH=12.060,P<0.01;OR=1.954,P<0.01).There was significant linear correlation(χ2=12.715,P<0.01);caries prevalence rate is in upgrade trend with aggravation of dental fluorosis(χ2=14.846,P<0.01).ConclusionBrick-tea type dental fluorosis has been predisposing factor of high incidence of dental caries.To reduce the occurrence of dental fluorosis should become one of the important measures to prevent dental caries for Tibetant students in local region.
