Aim: The aim of this study was to determine the association between periodontitis
and the incidence of preterm birth (PB), low birth weight (LBW) and preterm low birth
Material and Methods: One thousand and ninty-six women were enrolled.
Periodontal data, pregnancy outcome variables and information on other factors that
may influence adverse pregnancy outcomes were collected. Data were analysed using
a logistic regression model.
Results: The incidence of PB and LBW was 6.6% and 6.0%, respectively. The
incidence of PLBW was 3.3%. PB was related to motherÃ¢â‚¬â„¢s age, systemic diseases,
onset of prenatal care, previous PBs, complications of pregnancy, type of delivery, the
presence of untreated caries and the presence of periodontitis (odds ratio 1.77, 95%
confidence interval: 1.08Ã¢â‚¬â€œ2.88). LBW was related to motherÃ¢â‚¬â„¢s smoking habits,
ethnicity, systemic diseases, previous LBW babies, complications of pregnancy and
type of delivery. PLBW was related to motherÃ¢â‚¬â„¢s age, onset of prenatal care, systemic
diseases, previous LBW babies, complications of pregnancy and type of delivery.
Conclusions: The factors involved in many cases of adverse pregnancy outcomes
have still not being identified, although systemic infections may play a role. This study
found a modest association between periodontitis and PB. Further research is required
to establish whether periodontitis is a risk factor for PB and/or LBW.
