Use of alcohol-free antimicrobial mouth rinse is associated with decreased incidence of preterm birth in a high-risk population

Objective We sought to determine if treatment of periodontal disease during pregnancy with an alcohol-free antimicrobial mouth rinse containing cetylpyridinium chloride impacts the incidence of preterm birth (PTB) in a high-risk population. Study Design This single-blind clinical trial studied pregnant women (6-20 weeks' gestation) with periodontal disease who refused dental care. Subjects receiving mouth rinse were compared to designated controls who did not receive rinse (1 rinse:2 controls), balanced on prior PTB and smoking. Primary outcome was PTB
