Aim: To assess the prevalence of proximal enamel lesions, the need for non-operative caries treatment and the quality of dental restorations in 869 students aged 16 years from Northern Norway.

Methods: All first year upper secondary school students in Tromsø and Balsfjord municipalities were invited to participate in an oral- and general health project (Fit Futures).

Caries prevalence and distribution in individuals aged 3-20 years in Jönköping, Sweden: trends over 40 years.

Aim: To present and analyse changes in caries prevalence and caries distribution in child population sample groups in the city of Jönköping, Sweden, based on investigations performed in 1973, 1978, 1983, 1993, 2003, and 2013.
