[Validity of Self-Reported Periodontal Disease Questionnaire among Pregnant Women].

Objectives: As part of the Kumamoto RAINBOW Project, a multifaceted implementation of the prevention of premature labor, we investigated pregnant women's oral health status and assessed the validity of a self-reported periodontal disease questionnaire.

Methods: We examined the oral health status of pregnant women and asked them for subjective descriptions of symptoms of periodontitis both in the first and the second half of their pregnancy in Kumamoto Prefecture from August 2012 to January 2014. The Community Periodontal Index (CPI) was used to assess the periodontal condition, and women having periodontal pockets with depths of ≥4 mm were catecogorized as having periodontitis.
