Dental caries and restorations in teenargers. II. A longitudinal radiographic study of the caries increment of proximal surfaces among urban teenagers in Sweden.

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.

Dental caries and restorations in teenagers. I. Index and score system for radiographic studies of proximal surfaces.

An index and a score system for radiographical longitudinal studies of caries progression on proximal tooth surfaces are presented and compared with the DF-surface system. Generally, a good correlation between DF-surface differences and scores was found in a three-year study on teenagers. However, the score system seems to forward better means for a detailed study of the individual.
