title: Height of the residual ridge and radiographic appearance of bony structure in the jaws of clinically edentulous elderly people.
abstract: Alveolar atrophy and its relation to osteopenia 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 age-groups 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).
