摘要
目的：比较ICDAS龋病评估系统与WHO龋失补指数在中国儿童龋病流行病学研究的应用,评估ICDAS-Ⅱ系统的可行性。方法：对自愿参加天津医科大学口腔医院口腔健康检查的267名7-12岁儿童进行龋病检查,分别采用ICDAS-Ⅱ系统和WHO标准对每位受试对象进行评估。为了便于与WHO标准相比较,将ICDAS-Ⅱ系统的龋病分级标准,根据对龋的定义范围不同,分为健康和龋病两部分,具体分类如下：D1（0级为健康,1-6级为龋齿）;D2（0-1级为健康,2-6级为龋齿）;D3（0-2级为健康,3-6级为龋齿）;D4（0-3级为健康,4-6级为龋齿）。从性别,年龄等多方面分析比较两种龋病评估系统的患龋率和龋均。结果：ICDAS-Ⅱ系统检查者之间的Kappa值为0.74-0.84,WHO标准检查者之间的Kappa值为0.82,均具有良好的可重复性。ICDAS-Ⅱ系统与WHO标准比较,患龋率为86.1%比50.2%,乳牙龋均为2.38比1.19,差异均有统计学意义（P〈0.05）;ICDAS-Ⅱ系统D2、D3的患龋率及龋均明显高于WHO标准,差异有统计学意义（P〈0.05）;D4的乳牙龋均与WHO标准比较,差异无统计学意义（P〉0.05）。结论：ICDAS-Ⅱ龋病评估系统与传统的WHO标准相比有更高的龋病检出率,尤其对早期釉质龋有明显优势,是一个具有可行性的检测方法。
AIM： To evaluate the application of ICDAS-Ⅱ and WHO criteria in detection of caries in childrenand to the compare ICDAS-Ⅱ system with WHO criteria.METHODS： Two hundred and sixty-seven children（7~12 years old） who volunteered to receive oral health examination in stomatological hospital of Tianjin Medical University,were examined by 2 examiners using ICDAS-Ⅱ or WHO criteria respectively.The caries prevalence was analyzed using data obtained by WHO criteria（DMFT,DMFS,dmft and dmfs index） and by ICDAS-Ⅱ.According to different thresholds of caries,ICDAS-Ⅱ system was divided into sound and decayed at four cut-offs： D1（code1-6 classified as carious）;D2（code 0 and 1 as sound,2-6 as carious）;D3（code 0~2 sound,3~6 carious） and D4（0~3 sound,4~6 carious）.RESULTS： Kappa values for inter-examiner reproducibility were 0.74~0.84 for ICDAS-Ⅱ system and 0.82 for WHO criteria.Caries prevalence was 86.1% and 50.2%,dmft value was 2.38 and 1.19 in ICDAS-Ⅱ system and WHO criteria respectively.Caries prevalence rate and dmft value of D2 and D3 assessed by ICDAS-Ⅱ system were significantly higher than those of WHO criteria,and the difference was statistically significant（P〈0.05）.There was no significant difference of mean dmft between D4 and WHO criteria（P=0.31）.CONCLUSION： ICDAS-Ⅱ presents good feasibility in detecting caries lesions,especially non-cavitated caries lesions were described and classified in details.
