title: Oral Health Knowledge of Pregnant Women on Pregnancy Gingivitis and Children's Oral Health.
abstract: OBJECTIVE
  Pregnancy gingivitis and early childhood caries remain prevalent in Hong Kong. The aim of this study was to assess pregnant women's knowledge and beliefs related to pregnancy gingivitis and children's oral health.
  
  
  METHODS
  An outreach survey was carried out in a clinic that provided antenatal examination. A written oral health questionnaire related to pregnancy gingivitis and early childhood caries was administered to pregnant women. Of the 106 pregnant women who enrolled in the study, 100 completed the questionnaires.
  
  
  RESULTS
  Among the 100 subjects, only 39% correctly identified that hormonal changes contribute to pregnancy gingivitis. Only 36% identified red and swollen gums as signs of gingivitis. Furthermore, 53% of the surveyed pregnant women were not sure about the amount of toothpaste to administer to a child aged 18 months to 5 years. Almost 50% assumed that a replanted avulsed tooth would probably not survive within a short extra-alveolar period of less than 60 minutes.
  
  
  CONCLUSIONS
  Prenatal women generally lack knowledge of a common oral disease that occurs during pregnancy and of what constitutes adequate oral health care for children. Oral health care education should be implemented as part of a prenatal care program.
