Relationship of preterm premature rupture of membranes with periodontal diseases

Many factors lead the mothers to premature rupture of the amniotic membranes and preterm birth. Since periodontal diseases is considered as a risk factor for premature rupture of amniotic membranes، this study was performed to evaluate the relationship of premature rupture of membranes before term with periodontal diseases. This cases-control study was conducted on 100 pregnant women who referred to Qaem and Imam Reza hospitals in Mashhad، Iran from 2011-2012. Women were evaluated in two groups: 50 women in case group (preterm premature rupture of the amniotic membranes and gestational age37 weeks). Both groups were systemically healthy. In the examination، the indexes such as gingival bleeding، extent and severity of periodontal disease، tooth plaque and mean probing depth (MPD) were evaluated using William’s periodontal probe. Data was analyzed using SPSS software (version 16) and Fisher''s exact test، Chi-square، t-test، Mann-Whitney and t-student tests. there were significant differences in bleeding index، extent and severity index، and mean probing depth and tooth plaque index between case and control groups (P<0. 05). Periodontal diseases can be considered as an independent risk factor of preterm premature rupture of amniotic membranes.
