Periodontal treatment during pregnancy-no evidence of impact on preterm birth

Routine specialist pregnancy care involved an initial meeting to discuss quitting smoking and set a quit date, followed by 4 weekly telephone calls, and free nicotine replacement therapy for 10 weeks.

15 RCTs were included in this Cochrane review of impact of periodontal treatment on adverse pregnancy outcomes. all the included studies were considered to be at high risk of bias. There was no evidence that periodontal treatment reduces the number of preterm babies.
