Is caries prevalence underestimated in today's caries examination? A study on 16-year-old children in the county of Bohuslän, Sweden.

When caries prevalence was higher than today incipient lesions constituted 70% of carious lesions. Incipient lesions were often neglected in caries recordings and hence the true caries prevalence was underestimated. Moreover, it has been shown that there were evident differences in caries status between different areas in the same county though the preventive measures were supposed to be the same (Moberg Sköld et al 1984). To find out if the conditions were the same when caries prevalence has decreased a total number of 240 16-year-old children were examined concerning caries in 1987 and 1990. The results showed that the caries prevalence was still underestimated. Incipient lesions constituted 80% of the total number of carious lesions which was approximately the same as when caries prevalence was higher. The difference in caries status within the country had decreased compared with the study in 1984 (Moberg Sköld et al 1984).

Differences in caries status and caries recording within and between two counties in Sweden.

One-hundred and seventy-six randomly selected 16-year-old children from six clinics in two neighbouring counties were examined by the dentists who see the patients every year, as well as by two calibrated examiners (two of the authors). Compared to the dentists, working in the dental clinics, the authors consistently noted a higher total caries score (DMFS + incipient lesions). The differences were statistically significant in four of the six clinics and most pronounced on incipient lesions. Furthermore, there was a significant difference in caries prevalence between the two counties. Possible explanations for the difference are resources available and efforts put into preventive dentistry.

Caries increment and progression in teenagers when using a prevention- rather than restoration-oriented treatment strategy.

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.
