The significant positive factors in single variable analysis were further processed as independent variables when the presence of caries set as dependent variable, in a multivariate unconditional logistic regression model.[Results](1) Dental caries status of 5-year-old childrenThe prevalence of dental caries of primary teeth in 5-year-old children was 80.56%, the mean dmft was 5.31±4.54,filled teeth accounted for 2.56%,the mean dmfs was 9.91±11.35,filled teeth surfaces accounted for 4.42%.There was no statistical significance in the prevalence,dmft and dmfs between male and female. There was no statistical significance in the prevalence and dmfs between rural and urban areas children, but there was significant geographic divergences of the mean dmft for the whole observed group between rural and urban areas(P<0.05).The prevalence,dmft were higher than that of the third national oral health survey in 5-year-old children(P<0.05).(2) Oral hygiene status of 5-year-old childrenThe oral hygiene of 5-year-old children:DI-S 1.42±4.68.There were no statistical significance between gender, rural and urban areas.(3) Dental caries impact factors of 5-year-old childrenWhen the dental caries was taken as the dependent variable and the total of 11 positive factors in single variable analysis taken as independent variables,the results from a multivariate logistic regression model showed that the parents’educational level,frequency of consumption of desserts, interval of visiting the dentist,parents view about fluoride can prevention of dental caries are associated with the primary tooth caries.[Conclusion] (1)Guandu district in Kunming is a new urbanization area.In this area dental caries status of 5-year-old children was serious, but the filled tooth rate was very low.
