Evaluation of the temporomandibular joint (TMJ) pathologies with cone-beam computed tomography (CBCT) provides essential information about the bone structures of the TMJ. It is important to know the normal reference range when defining these pathologies. The aim of this study is to examine the morphometric and morphologic analyses of the bone structures of TMJ on the CBCT images in detail according to age, gender, and joint side.
A total of 35 parameters related to the condylar process, articular tubercle, mandibular fossa, ramus of mandible, and joint space were examined on the CBCT images. These parameters were compared with the joint sides and gender, and correlated with age.
Thirty-five parameters were evaluated. A statistically significant difference was found between genders in 22 parameters and joint sides in 6 parameters. When the correlation of parameters with age was examined; it was found that there was a very weak positive relationship in nine parameters, a weak positive relationship in one parameter, and a very weak relationship in the negative direction in two parameters.
In this study, the condylar process, articular tubercle, mandibular fossa, ramus of mandible, and joint spaces, which are usually examined separately in the literature, were examined, and the normal reference range was determined for all these parameters. We think that these normal reference ranges will be useful for researchers interested in TMJ pathologies.
使用锥形束计算机断层扫描（CBCT）评估颞下颌关节（TMJ）的病理变化，可以提供 TMJ 骨结构的重要信息。在定义这些病变时，了解正常的参考范围很重要。本研究的目的是根据年龄、性别和关节侧，详细检查 CBCT 图像上 TMJ 的骨结构的形态和形态分析。
在 CBCT 图像上共检查了与髁突、关节结节、下颌窝、下颌骨升支和关节间隙相关的 35 个参数。这些参数与关节侧和性别进行了比较，并与年龄相关。
评估了 35 个参数。在 22 个参数中，性别之间存在统计学差异，在 6 个参数中，关节侧之间存在统计学差异。当检查与年龄相关的参数时，发现 9 个参数呈非常弱的正相关，1 个参数呈弱正相关，2 个参数呈负向非常弱相关。
在这项研究中，我们检查了通常在文献中分别检查的髁突、关节结节、下颌窝、下颌骨升支和关节间隙，并为所有这些参数确定了正常参考范围。我们认为这些正常参考范围将对研究 TMJ 病变的研究人员有用。
