Objective: The increasing awareness of the relationship between maternal oral health and adverse pregnancy outcomes is well documented in the dental literature.The present review aims at summing up the current state of evidence and research on the same and sharing the available literature with the obstetric and other general practitioners so that the patients are diagnosed and treated with an interdisciplinary approach. Materials and methods: A search of the dental literature, including Medline Ò =PubMed through 2009, was conducted focusing on periodontal disease, preterm delivery, low birth weight, and intrauterine growth restriction was undertaken, and a hand search of other gray literature and text books was performed. Conclusions: It has been widely reported that pregnant women with periodontitis have more chances of having adverse pregnancy outcomes such as preterm birth, low birth-weight infants, preeclampsia, gestational diabetes, small-for-gestational age infants, and fetal loss. At the same time, there have been sporadic reports that contradict this potential association. Clinicians need to remain abreast with available and emerging information, and exercise prudence while considering the possible adverse pregnancy outcomes from chronic periodontal infections.
