简要总结

The purpose of this study is to determine whether maternal periodontal therapy (tooth cleaning) decreases the rate of preterm deliveries at <37 weeks gestation and to determine the effects of maternal periodontal therapy on the birth weight of infants born less than 37 weeks gestation.

详细描述

STUDY DESIGN:

The intervention is designed as a multi-center, randomized, controlled, clinical trial to determine the effects of periodontal therapy on the rate of preterm birth. Study participants will be assigned to one of two study arms. All pregnant women who present to the designated Obstetrical (OB) clinics are potential subjects for this study. A total of 1800 patients will be enrolled at 3 performance sites, enrolling about 600 subjects at each site at a rate of about 171 subjects/year at each site, randomly assigning these subjects to one of 2 treatment arms. Randomization will be performed using a computer-generated assignment scheme designed and performed in a masked manner by the data coordinating center. Each performance site will enroll about 300 subjects into each treatment group using the intent-to-treat principle, obtaining follow-up on all subjects. In treatment Group 1 participants will be assigned to standard localized periodontal therapy of scaling and root planning with subgingival polishing between three and six months of gestation. Group 2 will receive the same local periodontal therapy immediately following delivery.

MASKING:

The dental examiner will not be aware of the randomization treatment assignments of participants until after a complete baseline periodontal examination has been conducted. The study protocol allows the dental examiner to know the treatment assignment of participants but this knowledge will not affect the assessment of the primary obstetric outcome of the study. OB personnel or individuals collecting OB data will be masked as to dental treatments. At delivery the second dental exam will be made without the examiner knowing the pregnancy outcome.
