云南省耿马县佤族成人牙周健康状况调查及危险因素.

Objective To characterize adults periodontal health of the Wa nationality in Gengma County, Yunnan province, and to collect oral health knowledge and oral health behavior data and analyze related factors which affect the periodontal health status to provide evidence for prevention of local oral disease. Methods A total of 486 people were randomly selected from 10 natural villages in Gengma Dai and Wa Autonomous County, Yunnan province, and their periodontal health status was examined and questionnaires were conducted. EpiData 3.1 and SPSS 19.0 software were used for data entry and statistical analysis. Results The detection rates of gingival bleeding in 35～44, 55～64 and 65～74 years old group were 91.22%, 88.08%, 81.82%, respectively; and the detection rates of superficial periodontal pocket (4 ～5 mm) were 86.34%, 86.53%, 81.82%, respectively. Detection rate of deep periodontal pocket (≥6 mm) were 13.17%, 30.57%, 45.45%; Periodontal health rate were 12.68%, 14.51%, 18.18%, respectively. Combined with the contents of oral questionnaire survey, 7 statistically significant factors were screened as independent variables through single factor analysis, including age, education background, brushing frequency, self-perception of teeth, conscious toothache, smoking and the concept of tooth bleeding. Multivariate Logistic regression analysis showed that the worse the self-perception of teeth (OR = 1.500, P = 0.003), the more frequent the toothache (OR = 1.510, P = 0.017) and smoking (OR = 2.161, P = 0.014), the more likely Wa adults were to develop periodontitis. Higher education (OR = 0.527, P = 0.000) and more times of brushing teeth (OR = 0.519, P = 0.002) were the protective factors for the occurrence of periodontitis. Conclusion The detection rate of gingival bleeding, superficial periodontal pocket and deep periodontal pocket of Wa adults were higher than the fourth national level, the prevalence of periodontitis was higher, the oral health status was poor, far below the national oral health care target. It is necessary to increase the investment of medical resources in ethnic minority areas and strengthen the propaganda of oral health care for ethnic minorities so as to improve the diagnosis rate of periodontal diseases and the quality of life of the population.
