Abstract Objective. We assessed the relationships between (I) ultrasonography calcaneus T-scores (PIXI) and mandibular cortex characteristics on oral panoramic radiographs in older subjects; and (II) @entity170 and @entity2521 . Material and methods. We examined 778 subjects (53% @entity1 ) aged 59-96 years. @entity2521 was defined by alveolar @entity604 assessed from panoramic radiographs. Results. PIXI calcaneus T-values  <=-2.5 ( @entity170 ) were found in 16.3% of @entity1 and in 8.1% of @entity1 . PIXI calcaneus T-values <-1.6 ( @entity170 , adjusted) were found in 34.2% of @entity1 and in 21.4% of @entity1 . The age of the subjects and PIXI T-values were significantly correlated in @entity1 (Pearson's r = 0.37, P < 0.001) and @entity1 (Pearson's r = 0.19, P < 0.001). @entity2521 was found in 18.7% of subjects defined by alveolar bone level >= 5 mm. Subjects with @entity170 defined by adjusted PIXI T-values had fewer remaining teeth [mean difference 4.1, 95% confidence interval (CI) -1.1 to -6.5, P < 0.001]. The crude odds ratio (OR) of an association between the panoramic assessment of mandibular cortex erosions as a sign of @entity170 and the adjusted T-value (T-value cut-off <-1.6) was 4.8 (95% CI 3.1-7.2, P < 0.001; Pearson   (2) = 60.1, P < 0.001). A significant OR between @entity170 and @entity2521 was only found in @entity1 for the T-value cut-off  <=-2.5 (crude OR 1.8, 95% CI 1.1-3.3, P < 0.03). Conclusions. An association between @entity170 and @entity2521 was only confirmed in @entity1 . The likelihood that the mandibular cortex index agrees with adjusted PIXI T-values is significant.
