The objectives were to study the progression rate of approximal caries in 14 to 19-year-old adolescents and to assess the influence of experience of previous caries as a predictor of caries progression during the following years. The study population comprised 100 adolescents, all 19 years old, randomly selected. In all, there were 93 adolescents included in the study, for whom all sets of bitewing radiographs from 14 up to and including the age of 19 were assessed with respect to approximal caries. It could be noted that 32% of the adolescents had had at least one bitewing examination every year from 14 to 19 years of age. At the age of 14, 38% of the males and 24% of the females were radiographically without any sign of caries lesions (caries-free). The median survival time of initial caries in the present study was >5 years, while for manifest caries it was 3.2 years. It was found that 37% of the surfaces with manifest caries in males and 18% of the corresponding surfaces in females were restored within a year. The results show that experience of previous caries does not seem to be a significant indicator and does not influence when the next radiographic examination should be performed. It is thus concluded that individualized bitewing examination is the exception rather than the rule.
研究目的是探讨14至19岁青少年邻面龋的进展速度，并评估既往患龋经历作为未来几年龋病进展预测指标的影响。研究人群包括100名均为19岁的青少年，通过随机选取。共有93名青少年纳入研究，对其从14岁至19岁（含19岁）的所有咬合翼片进行邻面龋评估。值得注意的是，32%的青少年在14至19岁期间每年至少进行一次咬合翼片检查。14岁时，38%的男性和24%的女性在影像学上无任何龋损迹象（无龋）。本研究中初始龋的中位存活时间>5年，而明显龋的中位存活时间为3.2年。研究发现，男性中37%有明显龋的牙面和女性中18%相应牙面在一年内得到修复。结果表明，既往患龋经历似乎不是一个重要指标，也不影响下次影像学检查的时机。因此得出结论，个性化的咬合翼片检查是例外而非常规。
