Development of oral care during pregnancy for prevention of premature births

为了改善妊娠期口腔卫生，我们在调查妊娠期口腔内环境的基础上，制定了一套自我护理方案，并通过应用评估其效果。一项对132名孕妇和36名非孕妇的调查显示，怀孕增加了与牙周病无关的口腔细菌，降低了口腔卫生。对78名孕妇的应用证明了该计划的有效性，该计划包括：1)培训刷牙方法，使用特定的牙膏去除牙龈菌斑，并通过染色识别菌斑；2)提供有关牙周病的知识。

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.
