The study aimed to investigate caries prevalence in children using a severity grading diagnostic system, and to evaluate the influence of different diagnostic thresholds on the caries data. A group of 513 children, aged 5, 12 and 18 years, were examined clinically, and with available bitewing radiographs, by four calibrated examiners. The inter- and intra-examiner reliability, assessed by a weighted kappa, varied between 0.80 and 0.95. The mean dmft/DMFT values were 3.8, 5.8 and 11.0 for the three age groups respectively, and the corresponding dmfs/DMFS values were 5.4, 9.9 and 22.6. The d/D-component constituted the major part of the dmf/DMF index in all age groups, and enamel lesions accounted for 59%, 89% and 86% of the d/D-component in the three age groups respectively. It is concluded that enamel or initial caries lesions contributed substantially to the total caries prevalence, illustrating the importance of using diagnostic criteria that include all stages of clinical caries if a total picture of the caries situation is needed.
该研究旨在使用严重程度分级诊断系统调查儿童龋齿患病率，并评估不同诊断阈值对龋齿数据的影响。一组513名5岁、12岁和18岁的儿童由四名经过校准的检查人员进行临床检查，并使用可用的咬合翼片进行检查。通过加权kappa评估的检查者间和检查者内可靠性在0.80至0.95之间。三个年龄组的平均dmft/DMFT值分别为3.8、5.8和11.0，相应的dmfs/DMFS值分别为5.4、9.9和22.6。在所有年龄组中，d/D部分构成了dmf/DMF指数的主要部分，在三个年龄组中，釉质病变分别占d/D部分的59%、89%和86%。得出的结论是，釉质或初始龋损在总龋齿患病率中占很大比例，这表明如果需要了解龋齿情况的全貌，使用包括临床龋齿所有阶段的诊断标准非常重要。
