目的调查珠海市7~9岁儿童第一恒磨牙患龋率,并对其危险因素进行探讨。方法整群抽样选取珠海市两所小学7~9岁学生,将所有第一恒磨牙有龋患的学生作为病例组,无龋患的作为对照组,开展病例对照研究。结果珠海市7~9岁儿童第一恒磨牙患龋率8.2%,女生患龋率(10.2%)比男生(6.4%)高(RR=1.65,95%CI:1.15~2.62)。病例对照研究显示进食甜食习惯是危险因素,“每周至少一次”与“从不吃”的饮食习惯相比OR=2.18(95%CI:1.00~4.87)。“每天至少一次”与“从不吃”的饮食习惯相比OR=3.78(95%CI:1.00~3.90)。第一恒磨牙患龋与吃甜食有相关性(pearson相关检验,P<0.05)。结论进食甜食习惯是珠海市7~9岁儿童第一恒磨牙患龋危险因素。
