Objective To investigate the caries prevalence of the DongXiang、YuGu、BapAn minority people , we conducted an oral health investigation in three minority people that existed only in Gan Su province from urban and surburb .Methods According to the Third National Oral Health Survey Standards. 1200 children and adults in 5、12 and 35-44、65-74 age groups were selected for this study by random, cluster sampling method. Oral examinations were conducted on deciduous tooth caries experience in 5 age groups and permanent dentition dental caries condation in the 12 and 35-44、65-74 age groups.Results: Three minority people①caries prevalence rate (the prevalence of dental caries of primary dentition): In 5 year-age group. BaoAn’s higher than YuGu’s (p<0.01); DongXiang’s higher than YuGu’s (p<0.01); In 12 year-age group , BaoAn’s higher than DongXian’s g、YuGu’s in order (p<0.01) ; In 35-44 year- age group, BaoAn’s higher than DongXiang’s(p<0.05)、YuGu’s(p<0.01)。caries prevalence rate of BapAn female higher than male group(p<0.05); In 65-74 year-age group, BaoAn’s higher than YuGu’s、DongXiang’s (p<0.05). DongXiang and BaoAn female higher than male (p<0.05).②、Mean DMFT values(mean dmft values): In 5 year-age group, DongXiang’s higher than BaoAn’s, YuGu’s inorder (p<0.01) ; In 12 year-age group , both the caries prevalence rate and male-female ad rationem in the DongXiang’s、BaoAn’s、YuGu’s minority people group where no statistical significance.In 35-44 year- age group , BaoAn’s higher than YuGu’s、DongXiang’s (p<0.01) .The mean DMFT values of DongXiang’s and BapAn female were higher than male (p<0.05) ; In 65-74 year-age group , BaoAn’s were higher than YuGu、DongXiang (p<0.05) . BaoAn female was higher than male (p<0.05).③compared with National、GanSu: In 5 year-age group, the mean DMFT of DongXiang was higher than the National and GanSu province (p<0.05). BaoAn’s caries prevalence rate and the mean DMFT values was higher than the National (p<0.05) and lower than Gan Su province (p<0.05). YuGu’s caries prevalence rate and the mean DMFT values was lower than the National and Gan Su province (p<0. 05) . In 12 year-age group, the caries prevalence rate and mean DMFT values of DongXiang、BaoAn、YuGu、lower than the National and GanSu province (p<0.01) .The three minority people that the mean DMFT values was at low level. In 35-44 year-age group , BaoAn’s caries prevalence rate and mean DMFT values were higher than the National and GanSu province (p<0.01). DongXiang’s mean DMFT values was lower than the National (p<0.05).In 65-74 year-age group, the caries prevalence rate and mean DMFT values were higher than the National and GanSu province (p<0.01). Conclusions: The data of the investigat make up a deficiency of DongXiang、YuGu、BapAn’s dental hygiene。According to the WHO 12 year-age group caries epidemic degree valuation criterion , the 12 year-age group of the three minority people’s mean DMFT values were low。In the old age group’s c caries prevalence rate and the mean DMFT values higher than both Gansu and National。There were some difference in the three Minority , Most of the data of female caries prevalence rate and mean DMFT values was higher than male. It indicated that these three minority people with higher caries prevalence rate in our country . It should be emphasize that oral health education and enhance the consciousness of health care were very important for contribution to people’s healthy growth and physical quality improvement of these minority people .
