Abstract

AIM:

To assess the association between periodontitis and preterm birth in women of childbearing age.

MATERIALS AND METHODS:

This review included analytical case-control studies and prospective cohort studies evaluating the association between maternal periodontitis and preterm birth. Of the 3104 screened articles, 31 met the inclusion criteria for the review, and 20 met the quality criteria. The selected studies included a total of 10 215 women.

RESULTS:

Twenty articles contributed to the meta-analysis; 16 used a case-control design, and 4 were prospective cohort studies. The study heterogeneity was low (Q = 24.2464; P = 0.1869; I2  = 21.63%). A positive association between maternal periodontitis and preterm birth was found in 60% of the studies. Under the random-effects model, meta-analysis gave an odds ratio (OR) of 2.01 (95% CI 1.71, 2.36), representing a significant positive association between the explanatory and outcome variables.

CONCLUSION:

Pregnant mothers with periodontitis double the risk of preterm birth. There is a lack of international consensus for diagnosing maternal periodontitis.
