The aim of this study was to evaluate the status of occlusal surfaces of first permanent molars in 6- to 8-year-old children using the Caries Assessment Spectrum and Treatment (CAST) index and to assess how it correlates with DMF in the surveyed population.
A total of 1931 occlusal surfaces of first permanent molars in 6-8-year-old children from Bialystok District, Poland, were assessed using the DMF and the CAST indices. The prevalence and experience of different caries stages were evaluated. Data were statistically analysed with the Kruskal-Wallis test, the Dwass-Steele-Critchow-Fligner post-hoc test and the cross-tabulation. The intra-examiner reliability was evaluated. Results Caries prevalence on occlusal surfaces of the first permanent molars measured by DMF was 13.3% and by CAST -37.6%. The mean DMF was 0.33 and the mean D -0.07. For CAST, the mean values of early (codes 3-4) and advanced caries stages (codes 5-6) were 0.55 and 0.05, respectively. The DMF index statistically significantly increased with age. In the whole population the mean number of filled teeth was higher than the decayed ones. With reference to the CAST index, children showed increase in enamel lesions with age. The intra-examiner reliability was 0.94 for DMF and 0.88 for CAST. Conclusion The surveyed subjects showed a low prevalence of dental caries measured with DMF and a moderate prevalence when the CAST was used. The CAST index is a promising tool for epidemiological studies on caries. It provides more information on the disease prevalence, experience and severity compared to the DMF index.
本研究旨在使用龋病评估光谱和治疗（CAST）指数评估6至8岁儿童第一恒磨牙咬合面的状况，并评估其与调查人群中龋失补牙面（DMF）的相关性。
使用DMF和CAST指数对波兰比亚韦斯托克区6至8岁儿童的1931个第一恒磨牙咬合面进行评估。评估不同龋病阶段的患病率和患病情况。数据采用Kruskal-Wallis检验、Dwass-Steele-Critchow-Fligner事后检验和交叉表进行统计学分析。评估检查者内部信度。结果：通过DMF测量的第一恒磨牙咬合面龋病患病率为13.3%，通过CAST测量为37.6%。平均DMF为0.33，平均龋面（D）为0.07。对于CAST，早期龋病阶段（代码3 - 4）和晚期龋病阶段（代码5 - 6）的平均值分别为0.55和0.05。DMF指数随年龄增长有统计学显著增加。在整个人口中，补牙的平均数量高于龋坏牙。参照CAST指数，儿童的釉质病变随年龄增加。DMF的检查者内部信度为0.94，CAST为0.88。结论：调查对象用DMF测量显示龋齿患病率低，使用CAST时患病率为中等。CAST指数是龋病流行病学研究的一个有前景的工具。与DMF指数相比，它提供了更多关于疾病患病率、患病情况和严重程度的信息。
