In order to study the progression of proximal caries lesions and the quality of restorations, a sample of individuals in Gothenburg, Sweden was radiographically examined at the ages of 16, 19 and 22. By means of an index system every proximal tooth surface was given a diagnosis and differences between examinations were evaluated by a score system. Of all decayed and filled surfaces observed at the age of 22 more than 70% were already established at the age of 16. During the 16--19 year interval more than twice as many new carious lesions were developed than during the 19--22 year interval. The decrease in the number of new lesions during the last interval was accompanied by a slower progression of already existing lesions. Both factors resulted in a lower mean value with regard to scores during the 19--22 year interval compared with the preceding one. However, great individual differences were noted and 22 percent of the individuals exhibited larger score values during the last interval than during the first. Relatively seen the number of restorations with overhanging margins was lower at the final examination than at the previous ones.
为了研究邻面龋损的进展情况及修复体质量，对瑞典哥德堡的一组人群在16岁、19岁和22岁时进行了口腔X光检查。通过一个指标体系，对每个邻面牙齿表面进行诊断，并通过评分系统评估各次检查之间的差异。在22岁时观察到的所有龋坏和已充填表面中，超过70%在16岁时就已存在。在16至19岁期间出现的新龋损数量是19至22岁期间的两倍多。在最后一个时间段内新龋损数量的减少伴随着已存在龋损进展速度的减慢。这两个因素导致19至22岁期间的平均得分值低于前一个时间段。然而，个体差异很大，22%的个体在最后一个时间段内的得分值高于第一个时间段。相对而言，在最后一次检查时，边缘悬突修复体的数量比前几次检查时少。
