Abstract

Objective: To determine the Fractal Dimension (FD) and Mean Gray Value (MGV) changes caused by TMJ-OA on Cone-Beam Computed Tomography (CBCT) images.

Methods: Ninety patients were divided into three groups: Control group (bilateral unaffected joints), Unilateral group (one affected joint), and Bilateral group (bilaterally affected joints). Histogram Analysis (HA) and Fractal Analysis (FA) were performed on coronal slices of the condyles. p<0.05 was considered statistically significant.

Results: There was no statistically significant difference between the groups, and also total affected and total unaffected condyles in terms of both MGV and FD (p>0.05). There was a statistically significant difference between MGV and FD of the unaffected condyles in the Control and Unilateral groups (p<0.05).

Conclusion: Both MGV and FD of the unaffected condyles in the Unilateral group were significantly different from those in the Control group indicates that these patients may be potentially at risk for TMJ-OA in the advanced stage.

颞下颌关节骨性关节炎对髁突平均灰度值和分形维数的影响。

目的：探讨TMJ-OA对锥形束计算机断层扫描（CBCT）图像分形维数（FD）和平均灰度值（MGV）的影响。方法：90例患者分为3组：对照组（双侧未受影响关节）、单侧组（一侧受影响关节）和双侧组（双侧受影响关节）。髁突冠状面切片进行直方图分析（HA）和分形分析（FA）。结果：两组间MGV和FD的差异均无统计学意义，两组间全损髁和全损髁的MGV和FD的差异均无统计学意义（p < 0.05）。对照组和单侧组未患髁的MGV和FD差异有统计学意义(p)。结论：单侧组未患髁的MGV和FD均与对照组有显著差异，提示这些患者在晚期可能存在TMJ-OA的潜在危险。

期刊介绍： CRANIO: The Journal of Craniomandibular & Sleep Practice is the oldest and largest journal in the world devoted to temporomandibular disorders, and now also includes articles on all aspects of sleep medicine. The Journal is multidisciplinary in its scope, with editorial board members from all areas of medicine and dentistry, including general dentists, oral surgeons, orthopaedists, radiologists, chiropractors, professors and behavioural scientists, physical therapists, acupuncturists, osteopathic and ear, nose and throat physicians. CRANIO publishes commendable works from outstanding researchers and clinicians in their respective fields. The multidisciplinary format allows individuals practicing with a TMD emphasis to stay abreast of related disciplines, as each issue presents multiple topics from overlapping areas of interest. CRANIO''s current readership (thousands) is comprised primarily of dentists; however, many physicians, physical therapists, chiropractors, osteopathic physicians and other related specialists subscribe and contribute to the Journal.
