这份报告描述了培训的牙科检查员参加两个龋齿临床试验，并报告间和内部检查员的可靠性得分从最初的标准化会议。对研究检查员进行培训，以使用改良的ICDAS-II系统检测成人受试者中非空化和空化龋齿的视觉体征。龋病分为无龋（S）、非龋洞（D1）、釉质龋（D2）和牙本质龋（D3）。三个标准化会议涉及60名受试者和3604牙齿表面调用被用来计算几个措施的考官的可靠性。在标准化会议中观察到的龋齿患病率范围为1.4%至13.5%的冠状牙表面检查。对审查员之间的总体协议范围从0.88到0.99。除一名考官外，所有人都超过了0.60的类内系数阈值。检查者间未加权kappa值较低（0.23- 0.35），但加权kappas和观察到的kappas与最大kappas的比值更令人鼓舞（0.42- 0.83）。结果显示，在8名检查者中，有7名的Kappa值大于0.90，且在S/D1和D2/D3两级分类中Kappa值最高。报告了两个大型临床试验的初始检查员培训和标准化会议的方法和结果。建议其他规划考官培训和标准化会议提供。
This report describes the training of dental examiners participating in two dental caries clinical trials and reports the inter- and intra- examiner reliability scores from the initial standardization sessions. Study examiners were trained to use a modified ICDAS-II system to detect the visual signs of non-cavitated and cavitated dental caries in adult subjects. Dental caries was classified as no caries (S), non-cavitated caries (D1), enamel caries (D2) and dentine caries (D3). Three standardization sessions involving 60 subjects and 3604 tooth surface calls were used to calculate several measures of examiner reliability. The prevalence of dental caries observed in the standardization sessions ranged from 1.4% to 13.5% of the coronal tooth surfaces examined. Overall agreement between pairs of examiners ranged from 0.88 to 0.99. An intra-class coefficient threshold of 0.60 was surpassed for all but one examiner. Inter-examiner unweighted kappa values were low (0.23– 0.35) but weighted kappas and the ratio of observed to maximum kappas were more encouraging (0.42– 0.83). The highest kappa values occurred for the S/D1 vs. D2/D3 two-level classification of dental caries, for which seven of the eight examiners achieved observed to maximum kappa values over 0.90.Intra-examiner reliability was notably higher than inter-examiner reliability for all measures and dental caries classification systems employed. The methods and results for the initial examiner training and standardization sessions for two large clinical trials are reported. Recommendations for others planning examiner training and standardization sessions are offered.
