Abstract
Objective To study the situation of deciduous teeth caries of 5-year-old children from kindergartens in Shenyang. Methods Four hundred and forty resident 5-year-old children from 5 districts of Shenyang, 220 male and 220 female, were collected at random. The dentists checked the condition of deciduous teeth caries and calculated the caries prevalence rate and decayed, filled and missed (dfm) index, compared the data with the data of 1995, and conducted a questionnaire survey on the parents of children's eating habits and brushing habits. Results Prevalence rate of deciduous teeth caries was 67. 05% , and dfm index was 3. 10. Filling rate of deciduous teeth was 5.51% , the number of dental caries been filled was 8.41%. Compared with the data of 1995, the caries prevalence rate declined (P <0.001), and dfm index declined too (P < 0. 001). The ratio of children who ate sweet food before sleeping was 41.28% and the ratio of having a regular check for teeth was only 2. 04% according to questionnaire survey. Brushing teeth effectively with parental supervision accounted for 10. 17% , and parents who were satisfied with oral health status of children accounted for 82.91%. Conclusion Although caries prevalence rate of 5-year-old children in Shenyang kindergarten has declined compared with 1995 , but proportion was still high. Parents' lack of knowledge on oral health was related with high caries prevalence, and oral health education for parents should be strengthened.
