Abstract:

Objective:This studywas designed to examine whether the neonatal conditonmightbe related to the caries of deciduous teeth in pre-school children.Methods:1000 children from 3 years old to 6 years old in Chengdu were surveyed, and 260 children with dmft\6 and 260 caries-free childrenwere chosen. Data was collected by 200 pairs of useful questionnaire from their parents and analyzed by using logistic regression analysis andV2test.Results:The neonatal conditionwas closely relatedwith incidence rates of deciduous caries in pre-school children (P<0.05). The incidence rate of children with premature delivery was higher than that with full-term normal delivery (P<0.05). No significant difference was showed in children with full-term normal delivery and childrenwith dystrophy (P<0.05).Conclusion:There should be emphasis on the childrenwith premature delivery in caries pre- ventive cares.

Key words: deciduous caries, logistic regression
