Fractal Analysis of Temporomandibular Joint Trabecular Bone Structure in Patients with Rheumatoid Arthritis on Cone Beam Computed Tomography Images
Journal Title: Meandros Medical and Dental Journal - Year 2018, Vol 19, Issue 4
Abstract
Objective: The aim of this study was to evaluate the fractal dimension (FD) analysis in the temporomandibular joint for changes in trabecular bone structure on cone beam computed tomography (CBCT) images of patients with rheumatoid arthritis (RA). Materials and Methods: In this study 17 female RA patients and 16 healthy female individuals who were underwent CBCT imaging with for diagnostic purposes such as pathologic lesion and implant treatment planning, were evaluated and fractal analysis was performed using Image J (National Institutes of Health, Bethesda, MD) program with box-counting method. The results were analysed using Student t-test with SPSS 20.0 (SPSS, Chicago; IL, USA) software program. Results: According to the results, FD values of RA patients have wide range (for right side minimum: 0.919, maximum: 1.169 and for left side minimum: 0.958, maximum: 1.155). Statistical analysis of FD values showed significance between RA patients and the healthy individuals for both right/left sides (for the right side, the RA patients had a mean FD of 1.055, and the control group had a mean FD of 1.113; for the left side, the RA patients had a mean FD of 1.060, and the control group had a mean FD of 1.111) (p<0.05). There was no significant different between FD values of right and left side of mandibular condyle. Conclusion: RA patients have lower FD values than healthy individuals for each side which means bone complexity of RA patients are less. The results recommend that FD is a promising tool for detection of bone-related bone changes.
