The aim of the present study was to assess the changes in prevalence of early radiographic alveolar bone loss in a birth cohort (all subjects born 1970) over a period of 8 years as related to sex, ethnic origin, orthodontic treatment and socio‐economic status. In 1984, the target population consisted of 2767 subjects. In 1986, 1988 and 1992, sets of bite–wing radiographs were obtained from samples of the same population. Alveolar bone loss was recorded if the distance from the cemento‐enamel junction to the alveolar crest exceeded 2 mm measured on posterior bite‐wing radiographs. The frequency of subjects with radiographic alveolar bone loss increased significantly with age ( p ≤ 0.05). The number of subjects with 3 or more lesions also increased with age. The demographic variables studied did not seem to influence the prevalence of bone loss significantly in the present cohort study.
