Pregnancy is a holistic experience which suggests that every little thing that happens to the mother anyplace in or on her physique has the chance of influencing the infant. Adverse pregnancy outcomes including preterm birth, low birth weight, intrauterine growth restriction, are important events determining neonatal morbidity and mortality. In the present scenario the oral hygiene is the least cared for during pregnancy and owing to the high impact of dental disease on pregnancy outcome research into this area becomes mandatory. Keeping this in mind, this study was conducted to see the significant association of dental disease with adverse pregnancy outcome in MGM Hospital, Kalamboli, Navi Mumbai, so that in future dental examination can be made an integral part of antenatal check-up.
