To analyze the reproducibility of a calibration trial, at different diagnostic thresholds of dental caries, in a 12-month evaluation.
A group of dental examiners (n = 11), who had previous experience in epidemiological surveys, participated in the study. An initial training phase (theoretical and clinical) and five calibration exercises (baseline, 3, 6, 9 and 12 months) were arranged. World Health Organization (WHO) criteria, including the active initial lesions (IL) were used. Six- to 7-year-old children took part in the study. They were selected according to past history and dental caries activity. The data were analyzed at WHO and WHO + IL diagnostic thresholds in accordance with tooth and dental surfaces.
Excellent mean intra- and inter-examiner Kappa values were obtained for both diagnostic thresholds, in accordance with tooth and surface, during the calibration phases. However, the most relevant errors were related to the decayed component and to IL diagnosis.
It was possible to use the methodology proposed in this study in epidemiological surveys when examining the mixed dentition, although new strategies to improve training in IL diagnosis and calibration are necessary.
在一项为期12个月的评估中，分析在不同龋齿诊断阈值下校准试验的可重复性。
一组有流行病学调查经验的牙科检查人员（n = 11）参与了该研究。安排了初始培训阶段（理论和临床）以及五次校准练习（基线、3、6、9和12个月）。使用了世界卫生组织（WHO）的标准，包括活动性初始病变（IL）。6至7岁的儿童参与了该研究。他们根据既往病史和龋齿活动情况进行选择。根据牙齿和牙面，在WHO和WHO + IL诊断阈值下对数据进行了分析。
在校准阶段，根据牙齿和牙面，两种诊断阈值的检查者内和检查者间平均kappa值均极佳。然而，最相关的误差与龋损成分和IL诊断有关。
在检查混合牙列时，本研究提出的方法可用于流行病学调查，尽管需要新的策略来改进IL诊断和校准方面的培训。
