The prevalence of marginal bone loss was determined on bite‐wing radiographs in 2,409 15‐year‐old schoolchildren living in the county of Buskerud, Norway. Radiographs were collected from all dentists in the area participating in the Public Dental Service. A distance exceeding 2 mm from the cementoenamel junction to the alveolar crest was recorded as bone loss. Bone loss around one or more teeth was found in 11.3% of the subjects. More males than females were affected, with prevalences of 13.7 and 9.0%, respectively. Most of the lesions were observed adjacent to the maxillary first molars. Overt infrabony pockets were found in only a very few cases (0.5%). A clinical examination of 31 of the subjects could not distinguish those with and those without bone loss. The present study has demonstrated that alveolar bone loss is a common finding in 15‐year‐old school children. It is concluded that bite‐wing roentgenograms may be useful in the detection of early bone lesions in young individuals.
