摘　　要：目的了解山东省威海市学龄前儿童龋病与错颌畸形的发病率。方法随机抽取威海市6所幼儿园共942名儿童作为调查对象,统计龋病及错颌畸形的发病率。结果威海市学龄前儿童患龋率为62.63%,其中男童患龋率为60.86%,女童64.05%,男女童患龋率比较,差异无统计学意义(P>0.05)。患龋率随年龄增长呈递增趋势,且结果具有显著性差异(P<0.001)。口腔软组织异常的发病率为7.64%,错颌畸形患病率为12.42%。结论威海市学龄前儿童患龋率较高,男、女儿童患龋率无明显差异,但随着年龄的增长,患龋率逐渐升高。错颌畸形发病率较高,其中患病率最高的为前牙对刃或反颌。Objective To learn the incidence of dental caries and malocclusion in preschool children in Weihai in Shandong province.
