OBJECTIVE
This study aimed to determine, using cone beam computed tomography (CBCT) exams, whether chewing side preference (CSP) affects the anatomical parameters of the temporomandibular joints (TMJ) in individuals with temporomandibular disorders (TMD) of articular origin.
METHODS
A total of 106 CBCT exams were analyzed, divided into 56 exams of volunteers without a diagnosis of TMD (Control Group) and 50 exams from individuals diagnosed with TMD of joint origin (Experimental Group). The following parameters were analyzed: the axial and paracoronal shapes of the condyles, the degree of translation and rotation of the condyles, the volume of the condyles, and the height and inclination of the articular tubercles. Generalized estimation equations (GEE) were employed, and a significance level of 5% was set.
RESULTS
Only one significant interaction was observed between the two groups related to the axial shape of the condyle (p value < 0.001).
CONCLUSION
CSP did not influence the dynamic parameters of the TMJ in patients with TMD of articular origin.
目的
本研究旨在通过锥形束计算机断层扫描（CBCT）检查，确定咀嚼侧偏好（CSP）是否会影响关节源性颞下颌关节紊乱病（TMD）患者颞下颌关节（TMJ）的解剖学参数。
方法
共分析了106例CBCT检查，分为56例未诊断为TMD的志愿者检查（对照组）和50例诊断为关节源性TMD的个体检查（实验组）。分析了以下参数：髁突的轴向和副冠状面形状、髁突的平移和旋转程度、髁突体积以及关节结节的高度和倾斜度。采用广义估计方程（GEE），设定显著性水平为5%。
结果
两组之间仅观察到一个与髁突轴向形状相关的显著交互作用（p值<0.001）。
结论
CSP对关节源性TMD患者TMJ的动态参数没有影响。
