Research Abstract

To improve oral hygiene in pregnancy, we developed a self care program based on a survey of intraoral environment in pregnancy and evaluated its effect by application. A survey on 132 pregnant and 36 non-pregnant women showed that pregnancy increased oral bacteria unrelated to periodontal disease, and lowered oral hygiene. An application to 78 pregnant women proved effectiveness of the program consisting of 1) training of a brushing method removing gingival plaque with specific dental paste and identification of plaque by dyeing and 2) providing knowledge about periodontal disease.
