Xiao J, et al. – In this study, investigators examined the relationships among prenatal oral healthcare, early childhood caries (ECC) incidence, and Streptococcus mutans carriage in children aged < 6 years. They observed prenatal oral healthcare, including administration of fluoride supplements, oral examinations/cleanings, oral health education, dental treatment referrals, and xylitol gum chewing. They noticed a lower incidence of ECC and S. mutans carriage in the group that received oral healthcare intervention during pregnancy and early infancy vs the control group. They observed no differences in caries incidence in both the groups when fluoride supplementation was used during pregnancy.
