Abstract
BACKGROUND: Epidemiological studies of the association between smoking exposure and dental caries are limited. OBJECTIVE: The purpose of this cross-sectional study was to examine the association between prenatal and postnatal secondhand smoke (SHS) exposure and the prevalence of dental caries in primary dentition in young Japanese children. METHODS: Study subjects were 6412 children aged 3 years. Information on exposure to maternal smoking during pregnancy and postnatal SHS exposure at home was collected via parent questionnaire. Children were classified as having dental caries if one or more primary teeth had decayed or had been filled. RESULTS: Compared with never smoking during pregnancy, maternal smoking in the first trimester of pregnancy was significantly associated with an increased prevalence of dental caries in children (adjusted odds ratio=1.37, 95% confidence interval: 1.03-1.80). Postnatal SHS exposure was also positively associated with dental caries, with a significant positive exposure-response relationship. Compared with children not exposed to prenatal maternal smoking or postnatal SHS at home, those exposed to both prenatal and postnatal smoking had higher odds of dental caries (adjusted odds ratio=1.62, 95% confidence interval: 1.23-2.11). CONCLUSION: Our findings suggest that maternal smoking during pregnancy and postnatal SHS exposure may be associated with an increased prevalence of dental caries in primary dentition.
