FD analysis was performed on the condylar bone to establish standard FD values for normal, osteopenia, and osteoporosis conditions. The analysis was performed on the condylar bone using the box-counting method in ImageJ software to obtain FD values from skeletonized binary images of 30\u2009\u00d7\u200930 pixel regions of interest (ROIs) on both condylar heads.<\/jats:p>\n                  <jats:p>The normality of the data was assessed using the Shapiro\u2013Wilk test, and correlations between variables were evaluated using Spearman's rank correlation analysis.<\/jats:p>\n                  <jats:p>There was a significant positive correlation (p\u2009&lt;\u20090.001) between FD and BMD values, with moderate correlation strength (r\u2009=\u20090.462 for ROI 1 and r\u2009=\u20090.518 for ROI 2). Higher BMD values were associated with higher FD values, and vice versa.
