This cross-sectional study aimed to compare, by using Cone-Beam Computed Tomography (CBCT), temporomandibular joint (TMJ) morphology among patients with degenerative joint disease (DJD) with or without arthralgia, as well as a control group.
Thirty-one patients and their respective CBCT TMJ exams were assessed. These individuals were selected from an Orofacial Pain Service and classified into three groups based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD): group 1 (10 patients with TMJ DJD and arthralgia), group 2 (11 patients with TMJ DJD without pain), and group 3 (the control group, consisting of 10 healthy individuals without any signs or symptoms of TMD). A second examiner, who was calibrated and blinded for the patient's diagnosis, evaluated the CBCT images.
Group 1 showed a statistically significant association with the variables of erosion (p = 0.003) and osteophyte (p = 0.04) on the condyle surface, as well as concentric condyle position with reduced joint space (p = 0.01). The Kappa concordance index between the clinical diagnosis of DC/TMD and CBCT images was k = 0.134 (p ≤ 0.001).
The presence of erosion, osteophyte, and concentric condyle position with reduced joint space was statistically associated with DJD and ongoing TMJ joint pain.
本横断面研究旨在使用锥形束计算机断层扫描（CBCT）比较患有或不患有关节痛的退行性关节病（DJD）患者以及对照组之间的颞下颌关节（TMJ）形态。
评估了31名患者及其各自的CBCT颞下颌关节检查。这些个体选自口腔颌面疼痛科，并根据颞下颌关节紊乱病诊断标准（DC/TMD）分为三组：第1组（10名患有颞下颌关节DJD和关节痛的患者），第2组（11名患有颞下颌关节DJD但无疼痛的患者），以及第3组（对照组，由10名无任何颞下颌关节紊乱病体征或症状的健康个体组成）。另一名对患者诊断进行校准且不知情的检查者评估CBCT图像。
第1组在髁突表面的侵蚀（p = 0.003）和骨赘（p = 0.04）变量以及关节间隙减小的同心髁突位置方面显示出统计学上的显著关联（p = 0.01）。DC/TMD临床诊断与CBCT图像之间的Kappa一致性指数为k = 0.134（p≤0.001）。
侵蚀、骨赘以及关节间隙减小的同心髁突位置在统计学上与DJD和正在发生的颞下颌关节疼痛相关。
