The study assessed the correlation between DXA parameters (lumbar spine, femoral neck, total hip T-score, bone mineral density [BMD], and trabecular bone score [TBS]) and CBCT-derived indices (CT mandibular index superior [CTI(S)], CT mandibular index inferior [CTI(I)], and CT mental index [CTMI]).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Significant correlations were found between the CBCT indices and both quantitative (BMD, T-score) and qualitative (TBS) measures of bone mass.
