摘　　要：目的:调查北京市海淀区部分幼儿园36～42月龄儿童龋齿的患病情况和牙面分布情况,以了解该年龄阶段龋齿的分布特点,为指导早期预防幼儿龋提供依据。方法:选取北京市海淀区12所幼儿园,所有36～42月龄儿童为研究对象,2名经验丰富的儿童口腔医师依据WHO龋齿诊断标准进行口腔检查。结果:本研究共取样本630个,患龋儿童296名,患龋率47%。龋均(dmft index)2.17±3.31;龋面均(dmfs index)2.91±5.19。6≤dmft≤20的有90名,1≤dmft≤5的有206名。患龋牙面以乳磨面和上颌乳切牙邻面多见。结论:患龋牙大部分集中在患龋较重的儿童中,对于36～42月龄婴幼儿上颌乳切牙的邻面、上下颌乳磨牙的面是龋齿的高发牙面。对于患龋高危的患儿应早期干预,阻断龋齿的早期发生,并对重点好发患龋牙面应重点预防。Objective： To investigate the prevalence and tooth surface distribution of caries in young children. Methods： The caries prevalence and tooth surface distribution were studied in 630 of 36 - 42- month- old children in 12 kindergartens of Haidian district of Beijing by World Health Organization（WHO） diagnostic criteria for dental caries. Results： 47% of overall sample affected caries in 630 children. The mean dmft（s） score of the children was 2.17 ＋ 3.31 （2.91 ＋ 5.19）. In the distribution with dmft score, 6 ~〈 dmft ~〈20 was found in 90 subjects, 1 ~〈dmft~〈 5 in 206. The surfaces of teeth most often affected were the occlusal of deciduous molars and proximal surface of maxillary deliciduous central and lateral incisor. Conclusion： Most affected teeth concentrated in the children with heavier caries. Measures must be taken to intervene and block the occurrence of early children caries. Attention should be paid to the most often affected teeth surface.
