The aim of the present study was to assess the prevalence of radiographic alveolar bone loss, as related to selected background variables in 2767 14‐year old schoolchildren. Bone loss was recorded when the distance from the cemento‐enamel junction to the alveolar crest exceeded 2 cm. The radiographs were magnified approximately 10 times. 3% of the subjects and 18.5% of the sites were excluded because of indistinct radiographic reference points. Radiographic bone loss was found in 5% of the subjects. Horizontal lesions were more prevalent than vertical defects. Most subjects with bone loss had 1 (75%) or 2 (22%) lesions. No subject was diagnosed with juvenile periodontitis kind of lesion. The prevalence of bone loss depended on the variables sex. orthodontic treatment and ethnic background.
