Coinciding with the decline in caries prevalence observed among children and adolescents, changes in the distribution and progression rates of the disease have been found. The aim of this study was to assess occlusal and approximal caries behaviour and disease distribution within a group of Danish teenagers, and to determine whether the presence of occlusal fillings at baseline could be used as predictor for caries behaviour. The material used was bitewing radiographs taken twice in 197 adolescents, at the age of 14.5 years (first examination) and approximately 3 years later (second examination). Of the occlusal surfaces assessed at both examinations, 93% remained unchanged, 1% developed new carious lesions, and 6% had been filled during the study period. All occlusal dentinal lesions found at the first examination and left unrestored during the study period did not appear to have progressed. Of the approximal surfaces, 86% remained unchanged, 9% developed caries, 2% showed caries progression, and 2.5% had been filled during the study period. 22% of the approximal enamel lesions found at the first examination progressed into the dentine during the study period. 18% of all the children were responsible for 50% of the total number of new lesions and fillings. The proportion of children exhibiting new lesions at the second examination was almost evenly distributed among children with and without occlusal fillings at the first examination. In the group of children with occlusal fillings at baseline, significantly more individuals than in the other group showed new fillings and lesions with and without progression. It is concluded that the progression percentage for approximal enamel lesions to penetrate into the dentine was low, that the distribution of new carious lesions and fillings among the children was polarized, and that the presence of occlusal fillings at baseline could not be used to identify children with a specific caries behaviour.
与儿童和青少年中观察到的龋齿患病率下降相一致，人们发现了该疾病在分布和进展速度方面的变化。本研究的目的是评估一组丹麦青少年的咬合面和邻面龋齿行为及疾病分布，并确定基线时咬合面充填物的存在是否可作为龋齿行为的预测指标。所使用的材料是197名青少年在14.5岁时（第一次检查）和大约3年后（第二次检查）拍摄的咬合翼片。在两次检查中评估的咬合面中，93%保持不变，1%出现新的龋损，6%在研究期间已进行充填。在第一次检查时发现且在研究期间未进行修复的所有咬合面牙本质病变似乎都没有进展。在邻面中，86%保持不变，9%发生龋齿，2%显示龋齿进展，2.5%在研究期间已进行充填。在第一次检查时发现的22%的邻面釉质病变在研究期间进展为牙本质。所有儿童中有18%的人导致了新病变和充填物总数的50%。在第二次检查时出现新病变的儿童比例在第一次检查时有咬合面充填物和没有咬合面充填物的儿童中几乎均匀分布。在基线时有咬合面充填物的儿童组中，与另一组相比，有更多个体出现新的充填物和有或无进展的病变。得出的结论是，邻面釉质病变进展至穿透牙本质的比例较低，儿童中新龋损和充填物的分布呈两极分化，并且基线时咬合面充填物的存在不能用于识别具有特定龋齿行为的儿童。
