Many recent studies have evaluated the relation between periodontitis and pregnancy complications. This study aimed to examine the association between preeclampsia and periodontitis in Indian women. A total of 130 pregnant women were enrolled between 26-32 weeks of gestation. Oral health examinations were performed at recruitment and again within 48 hours of delivery to determine the presence and/or progression of periodontitis in all subjects. Pocket depth, clinical attachment loss (CAL), and gingival index were measured in all subjects. There was significant (p < 0.05) difference between the preeclampsia and normotensive groups in the distribution of periodontitis both at recruitment and after delivery. Multiple logistic regression demonstrated that periodontitis both at enrolment (OR = 5.78, 95% CI 2.41-13.89) as well as within 48 hours of delivery (OR = 20.15, 95% CI 4.55-89.29), may be associated with an increased risk of preeclampsia.
