摘　　要：目的采用ICDAS系统评估学龄前儿童乳牙患龋状况。方法采用整群随机抽样方法,抽取临安市5所幼儿园2.5～4.5周岁的491名学龄前儿童进行口腔检查,并用国际龋病探测和评估系统（ICDAS）对儿童乳牙龋坏状况进行评估。结果以ICDAS系统0～2级为健康,3～6级为龋齿的标准,受检儿童乳牙患龋率和龋均分别为66.80%和3.98,龋面均5.77,男女童患龋率比较差异无统计学意义（P〉0.05）。早期釉质龋占24.44%;牙合面患龋最高,占32.90%;舌腭面患龋最少,占7.62%;咬合面和近远中面龋坏占大多数。结论临安市2.5～4.5周岁学龄前儿童龋病患病率较高。ICDAS龋病评估系统应用于龋病流行病学调查对于发现早期釉质龋坏有重要意义,有利于儿童龋病的早期防治。Objective To evaluate the status of dental caries of deciduous teeth with International Caries Detection and Assessment System（ ICDAS） among preschool children in Lin ＇an city. Methods A total of 491 children from 5 kindergartens aged 2. 5 to 4. 5 years were enrolled using the cluster random sampling method and were examined with the modified criteria of ICDAS. Results The caries rate of deciduous teeth was 66. 80% among the tested children. The mean DMFT score was 3. 98 and the mean DMFS score was 5. 77. The prevalence rate was of no significant difference between genders（ P〈0. 05）. Early enamel caries rate was 24. 44%,while the caries were found most frequently on the occlusal and proximal surface（ 32. 90%） and least frequently on the tongue palatal surfaces（ 7. 62%）. Conclusion The prevalence rate of deciduous dental caries among preschool children is relatively high in Lin＇an city. ICDAS might be used to early prevention and diagnose of dental caries.
