Cone-beam computed tomography (CBCT) enables the radiographic examination and evaluation of osseous changes in the temporomandibular joint (TMJ).
The aim of this study was to determine the prevalence of various bony changes in TMJ in patients from a wide age range as well as to evaluate the CBCT findings of TMJ osteoarthritis (OA) and correlate them with age.
The study included the CBCT images of 150 patients (43 males and 107 females) who were refferred to the Department of Dentomaxillofacial Radiology for the evaluation of TMJs. Each TMJ was evaluated separately for the presence of any osseous changes in the condylar head or articular fossa/eminence, and for joint space narrowing.
The mean age of the sample was 37.26 years (range: 10-90 years). A total of 101 (67.3%) patients presented 1 or more osseous changes. No significant differences were found between the right and left TMJs concerning the prevalence rates of osseous changes. Significant differences were found in the mean ages with regard to the absence and presence of the following findings: condylar erosion, osteophytes, loose bodies, erosion in the articular fossa, and joint space narrowing.
Degenerative changes in TMJ may reflect an age-related bone remodeling process. Older patients may have more common findings of OA, such as condylar and articular erosion, osteophytes, loose joint bodies, and joint space narrowing.
锥形束计算机断层扫描（CBCT）能够对颞下颌关节（TMJ）的骨质变化进行影像学检查和评估。
本研究旨在确定不同年龄范围患者TMJ各种骨质变化的患病率，并评估TMJ骨关节炎（OA）的CBCT表现及其与年龄的相关性。
本研究纳入了150例患者（43例男性和107例女性）的CBCT图像，这些患者因TMJ评估被转诊至口腔颌面放射科。分别对每个TMJ的髁突头部或关节窝/关节结节的骨质变化以及关节间隙变窄情况进行评估。
样本的平均年龄为37.26岁（范围：10 - 90岁）。共有101例（67.3%）患者出现1种或更多骨质变化。在骨质变化患病率方面，右侧和左侧TMJ之间未发现显著差异。在以下表现的有无方面，平均年龄存在显著差异：髁突侵蚀、骨赘、游离体、关节窝侵蚀和关节间隙变窄。
TMJ的退行性变化可能反映了与年龄相关的骨重塑过程。老年患者可能更常见OA的表现，如髁突和关节侵蚀、骨赘、关节游离体和关节间隙变窄。
