[A study on the relationship between deciduous tooth caries in pre-school children and their neonatal conditions].

OBJECTIVE

This study was designed to examine whether the neonatal conditIon might be 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 > or = 6 and 260 caries-free children were chosen. Data was collected by 200 pairs of useful questionnaire from their parents and analyzed by using logistic regression analysis and chi 2 test.

RESULTS

The neonatal condition was closely related with 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 children with dystrophy (P < 0.05).

CONCLUSION

There should be emphasis on the children with premature delivery in caries preventive cares.
