Abstract：Objective Through the analysis of epidemic situation of dental caries in preschool children aged 3-5 years in Baotou city,to discuss the relationship between caries situation and the degree of dental caries activity.Methods Totally 379 children(male 196,female 183)were selected in 5 kindergartens for dental caries cxamination with random choice.The dental caries rate,decayed or filled teeth (dft)and caries severity index (CSI)were calculated.Caries activity (CAT) was measured by caries activity test.Results The caries rates,dental filling teeth (dft)and caries severity index (CSI)respectively were 56.20％,3.82 and 10.11 in 3-5 years old children in Baotou city.There was no statistically significant difference between male and female (P ＞ 0.05).The incidence of caries,dft and CSI had no statistically significant difference in all age groups (P ＜ 0.05).There was no difference in dft and CSI when CAT were at the degree from 0 to land from 2 to 3 when each two groups were compared (P ＞ 0.05).Others had statistically significant difference (P ＜ 0.05).CAT was positively correlated with dft and CSI at each degree (r =0.394 and 0.363,P ＜ 0.05).Conclusion Caries activity test can reflect the degree of decay effectively and accurately.It is important to screen for high-risk caries patients in children.Reasonable prevention and treatment measures should be developed in response to the caries situation in school-aged children in Baotou city,in order to lay a solid foundation for preventing caries in children.
