Abstract
Objective. The mode of delivery may significantly influence the diversity and composition of the oral microflora and facilitate early acquisition of mutans streptococci. The aim was to compare caries prevalence and experience in 3-year-old children delivered vaginally and by caesarean section (C-section). Materials and methods. The study had an observational cohort protocol based on extracted information from governmental databases and nationwide registers concerning birth, social and educational levels and dental status. Children born at the Copenhagen University Hospital in 2005 were eligible and the final study group with complete information consisted of 594 children, 443 delivered vaginally and 151 by C-section. Results. The total caries prevalence was 8% and no significant difference was displayed between the groups. When only the children with caries (dmfs > 0) were compared, those delivered by C-section had a higher mean value in comparison with those delivered vaginally (dmfs 6.8 vs 3.2), but the difference was not statistically significant. There was a significant relationship between caries prevalence and low family income in the total study group (OR = 5.8, p < 0.05). Conclusions. Within the limitations of this observational cohort study, caries prevalence in 3-year-old children was not related to the mode of delivery. However, the tendency of more severe caries in the C-section group justifies further studies, preferably with a prospective design.
