SUMMARY Alveolar atrophy and its relation to osteo‐penia of the mandible were studied in 124 edentulous 76‐, and 81‐ and 86‐year‐old subjects (32 males and 92 females). Both variables were assessed visually from panoramic radiographs. Mandibular alveolar atrophy was found to be more severe in women (P < 0.001). No statistically significant differences were found between the three age‐groups in mandibular alveolar atrophy, nor between the sexes or agegroups in maxillary alveolar atrophy. The structure of the mandibular bone was osteopenic in 38 patients (30.7%), a situation that was more frequent in women (P < 0.001). The relationship between the observed osteopenia and the severity of the mandibular alveolar atrophy in women was statistically significant (P < 0.05).
