Periodontal disease treatment does not affect pregnancy outcomes

David Leader DMD, MPH Associate Clinical Professor, Tufts University .


Systematic Review Conclusion

Periodontal disease treatment does not lower the risk of preterm birth, low birth weight or both.

Critical Summary Assessment

Although periodontal disease treatment is recommended during pregnancy, the results of a systematic review of 13 randomized controlled clinical trials, for which a meta-analysis was conducted in 11 of the trials, do not indicate that there is a lower risk of preterm birth or low birth weight.
