Within a group of 16 year old school children leaving the regular school dental care, the number of carious lesions and fillings in proximal tooth surfaces was radiographically studied, using an index system. Three years later, the same individuals were re-examined. The results showed that intact surfaces and surfaces with small carious lesions were more resistant to change than others. A minority of the individuals was found to be responsible for a majority of the lesions established during the three year interval. Generally, the progress of caries was slow.
在一组离开常规学校牙科护理的16岁学童中，使用一种指数系统对近端牙面的龋损和补牙情况进行了影像学研究。三年后，对同一批个体进行了重新检查。结果表明，完整牙面和有小龋损的牙面比其他牙面更不易发生变化。发现少数个体导致了三年期间出现的大多数龋损。总体而言，龋齿进展缓慢。
