The objective of this study was to compare ICDAS and DMFT/S in the evaluation of caries status of the first permanent molar in 200 children aged 7 to 13 years.
This was a cross-sectional design study. Participants were selected from two private schools in Lebanon. The examinations were performed by two trained and calibrated examiners using a dental mirror and a WHO probe. The number of decayed (D), missing (M) and filled (F) teeth was recorded in DMFT/S form, and the numbers related to D, M and F were then added to record the DMFT/S value (D1MFT/S, D2MFT/S and D3MFT/S). In the ICDAS, the assessment of caries associated with restorations and sealant was recorded. Student t tests/and Mann-Whitney tests were used to compare the continuous variables. Chi-square tests and Fisher exact tests were used to compare the categorical variables.
The average age of the participants was 9.21 ± 1.927 (7-13 years old). No significant difference was found between the mean time to score DMFT, DMFS and ICDAS indices (-p-value > 0.05). The prevalence of caries with D1MFS, D2MFS and D3MFS was 80.5%, 54% and 30.5%, respectively. However, the prevalence of caries with ICDAS II was 77.5%.
The DMF index is an international user-friendly system that shows the carious history of teeth. However, the ICDAS assesses the different stages of caries and describes the restorative status of the tooth, promoting new preventive approaches and curative needs. More studies should be done to confirm these findings.
本研究旨在比较国际牙科联合会（FDI）龋病检测系统（ICDAS）和世界卫生组织（WHO）口腔健康调查基本方法（DMFT/S）在评估 7-13 岁儿童第一恒磨牙龋病状况方面的差异。
这是一项横断面设计研究。参与者从黎巴嫩的两所私立学校中选取。检查由两名经过培训和校准的检查人员使用口腔镜和 WHO 探针进行。DMFT/S 形式记录了龋齿（D）、缺失（M）和填补（F）的牙齿数量，然后将与 D、M 和 F 相关的数字相加，记录 DMFT/S 值（D1MFT/S、D2MFT/S 和 D3MFT/S）。在 ICDAS 中，评估了与修复体和封闭剂相关的龋病。采用 Student t 检验/和 Mann-Whitney 检验比较连续变量。采用卡方检验和 Fisher 确切概率法比较分类变量。
参与者的平均年龄为 9.21±1.927（7-13 岁）。DMFT、DMFS 和 ICDAS 指数评分的平均时间无显著差异（-p 值>0.05）。D1MFS、D2MFS 和 D3MFS 的龋病患病率分别为 80.5%、54%和 30.5%，而 ICDAS II 的龋病患病率为 77.5%。
DMF 指数是一种国际通用的友好系统，可显示牙齿的龋病史。然而，ICDAS 评估了不同阶段的龋病，并描述了牙齿的修复状态，促进了新的预防方法和治疗需求。需要进一步开展更多的研究来证实这些发现。
