目的 了解母亲孕期相关因素对学龄前儿童龋齿的影响,为有针对性制定保护乳牙的措施提供参考依据。方法 用病例对照的方法,对全市城区22所幼儿园3 243名3～6岁在园健康儿童作为研究对象,1 408例患龋儿童作为病例组,1 835名未患龋儿童作为对照组,同时调查母亲孕期及围生期的相关因素。结果 母亲孕期患龋或牙髓炎、牙龈炎,孕期补充蛋白质、钙等、孕期吸烟或被动吸烟、早产对儿童龋齿患病率有影响,差异有统计学意义(P<0.05),多因素Logitic回归分析,结果显示孕期补充蛋白质、钙剂等是学龄前儿童龋齿保护因素,母亲孕期患龋齿、母亲孕期主动或被动吸烟是儿童龋齿的危险因素。结论 母亲孕期相关因素对学龄前儿童龋齿的发生有影响,应加强孕期营养、口腔和全身保健,保护乳牙,促进儿童健康成长。
