An Epidemiological Investigation Of Dental Caries Among Uygur Adults In The Moyucountry, Xinjiang

Objective:To investigate the status of dental caries among uygar adults in Moyu country,Xinjiang.So as to provide epidemiological foundation for prevention of dental caries in the remote countryside of southern Xinjiang. Methods:According to the critetia recommended by the Third National Oral Health Investigation and Oral Health Surveys Basic Methods of World Health Organization,the subjects were sampled randomly with stratify capacity from 20 villages among 364 villages.Oral examinations were conducted on permanent tooth caries experience.Dental caries data of 2537 uygur adults residents(age≥18years) in the Moyu county,Xingjiiang were analyzed using Spss17.0 software package. Results:The prevalence of dental caries and mean DFT of 2537 individuals were 88.92% and 4.889 ± 3.487 respectively.Prevelance of dental caries and mean DFT appears to decrease with increasing age, there were statistical significance in age distribution; age two two comparisons among caries, in 18~34 years old group, and the 35~44 year old group, the difference was statistically significant between other groups(p<0.05); in the 18~34 year old, 35~44 years old group, the female rate of caries, caries all were higher than males, the difference was statistically significant(p<0.05); 2537 adults coronal caries rate is 78.20%, the root caries rate was 63.26, the rate of dental caries appears to decrease with increasing age, the differences between groups was statistically significant(p<0.05), root caries rate at 18~44 year old age group increased with age, and in the 45~65 age group appears to decrease with increasing age, root caries rate in the age groups had significant difference(p<0.05); due to caries filling rate was 0.70%, the lowest rate of filling group for the age group over 65 years old, only 0.42%, filling rate in the age groups and gender differences had no statistical significance(p>0.05). Conclusion:The permanent tooth caries prevalence rate of uygur adults is still relatively high in Moyu country,Xinjiang, there remains a proportion of active untreated decays. Furthermore, oral hygiene publiczing and education should be carried out and more dental care services should be provided for the remote countryside in southern Xinjiang.
