In a group of young teenagers restorative treatment on approximal carious surfaces was postponed until carious lesions were radiographically detected in the dentine, permitting a reallocation of resources to preventive care. The development of new lesions and the rate of progression of unrestored lesions were studied by means of bitewing radiographs obtained at 13 and 16 years of age. Of the radiographically sound surfaces at age 13, 1.3% developed dentinal lesions within the three year period. Approximately 18% of outer enamel lesions and about 55% of inner enamel lesions progressed into the dentine. The number of new lesions as well as the rate of progression varied between groups of patients exhibiting different caries experience at age 13. A total of 1.2 surfaces per patient required restorative treatment according to the treatment strategy applied compared to 5.3 if all radiographically diagnosed lesions would have been restored.
在一组青少年中，邻面龋损的修复治疗被推迟，直到在X线片上检测到龋损累及牙本质，这样可以将资源重新分配到预防保健上。通过在13岁和16岁时拍摄的咬合翼片研究新龋损的发生情况以及未修复龋损的进展速度。在13岁时X线片显示健康的牙面中，有1.3%在三年期间发展为牙本质龋损。大约18%的外釉质龋损和55%的内釉质龋损进展到牙本质。新龋损的数量以及进展速度在13岁时具有不同龋病经历的患者组之间有所不同。根据所应用的治疗策略，每位患者平均需要1.2个牙面进行修复治疗，而如果对所有X线片诊断出的龋损都进行修复，则平均每位患者需要5.3个牙面。
