en Correlation of Bone Mineral Density and Fractal Analysis of the Mandibular Condyle in Women with Temporomandibular Joint Osteoarthritis: A Pilot Study Radiology Radiology Original article Original article <div> <table align="center" hspace="0" vspace="0"> <tbody> <tr> <td style="padding: 0in 12px; text-align: justify;" valign="top">Background and Aim: Temporomandibular joint osteoarthritis (TMJOA) appears to be more common in osteoporotic patients. Fractal analysis is a mathematical method that can be used to assess trabecular bone. The aim of this study was to assess the correlation of bone mineral density (BMD) and fractal dimension (FD) of the condyles in women with TMJOA using cone-beam computed tomography (CBCT).   Materials and Methods: In this cross-sectional study, the FD and lacunarity of the condylar head were assessed on CBCT images of 39 women (20 healthy women with no signs/symptoms of TMJOA, and 19 TMJOA patients). The BMD and the T-score of the hip and lumbar vertebrae were determined using dual energy X-ray absorptiometry. Data were analyzed by t-test, chi-square test, and Pearson’s correlation coefficient. Results: TMJOA patients and healthy controls did not differ significantly in terms of the mean age (P=0.63), BMD and T-score (P>0.05), or FD and lacunarity (P>0.05). A significant correlation was observed, however, between lacunarity in the two condyles (r=0.47, P=0.003) and BMD of the lumbar vertebrae and the hip (r=0.40, P=0.01).  </td> </tr> </tbody> </table> </div> <div style="text-align: justify;">   Conclusion: The mean BMD of total spine and hip did not differ significantly in the two groups of healthy controls and TMJOA patients. The FD and lacunarity also       showed no significant difference between the groups. FD based on CBCT images of the TMJ is not a reliable indicator for categorization of skeletal status.  </div> Osteoarthritis, Fractals, Cone-Beam Computed Tomography, Bone Density 210 218 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-812-2&slc_lang=en&sid=1 M Imanimoghaddam imanim@mums.ac.ir 100319475328460010554 0000000247057018 No Department of Oral and Maxillofacial Radiology, School of Dentistry, Mashhad University of Medical Sciences, Mashhad, Iran A Bagherpour bagherpoura@mums.ac.ir 100319475328460010555 0000000262811867 Yes Department of Oral and Maxillofacial Radiology, School of Dentistry, Mashhad University of Medical Sciences, Mashhad, Iran A Madani madania@mums.ac.ir 100319475328460010556 0000000299330645 No Department of Prosthodontics, School of Dentistry, Mashhad University of Medical Sciences, Mashhad, Iran M Foroozandeh drforoozandeh1991@yahoo.com 100319475328460010557 0000000241432112 No Department of Oral and Maxillofacial Radiology, Dental School, Hamadan University of Medical Sciences, Hamadan, Iran F Hafez Maleki shahin_m70@yahoo.com 100319475328460010558 0000000313037729 No Department of Oral and Maxillofacial Radiology, Dental School, Hamadan University of Medical Sciences, Hamadan, Iran M Alimohammadi mona_y28@yahoo.com 100319475328460010559 0000000317082375 No Department of Oral and Maxillofacial Radiology, School of Dentistry, Mazandaran University of Medical Sciences, Sari, Iran SH Moeini moeinish971@mums.ac.ir 100319475328460010560 0000000152516218 No Department of Oral and Maxillofacial Radiology, School of Dentistry, Mashhad University of Medical Sciences, Mashhad, Iran
