【摘要】 目的:为调查杭州市幼儿喂养龋患病率及相关因素,从而降低我国的总患龋率。方法 采用分层抽样方法对杭州市区 1998年 593名 2.5～3岁入托幼儿由专人进行口腔检查并询问有关事项。结果 调查中喂养龋总发生率达 48.74％。男女之间,母乳喂养与人工喂养之间喂养龋发生率无显著性差异(P>0.05)。?的患龋率分别高达40.68％,39.32％,占总龋数的 49.22%。母乳喂养至 7～12月组与 0～6月组相比,1～2岁组与 7～12月组相比患频率均明显增高(P<0.01)。加糖喂养、含奶睡、2.5岁前来刷牙、父母串龋均与喂养龋发生密切相关。结论:喂养龋在我国高发,其发生与乳汁接触时间、遗传因素、不良生活习惯成正相关。为降低我国的总患龋率,必须从婴儿萌出第一颗乳牙起即清洗牙面及口腔,注意平衡婴幼儿体内有关元素水平。更多还原
