OBJECTIVE
To evaluate the relationship between temporomandibular disorders (TMD) and craniocervical posture in the sagittal plane measured from lateral radiographs of the head.
METHODS
The sample was comprised of 80 randomly selected students of dentistry at the Federal University of Rio Grande do Norte. Research Diagnostic Criteria for TMD (RDC/TMD) was used to evaluate the signs and symptoms of TMD. Lateral radiographs of each individual were used to measure the position of the hyoid bone, the craniocervical angle, and the occiput-atlas distance. A chi-square test was used to evaluate the relationships between craniocervical posture measures and TMD.
RESULTS
No relationship was found between TMD and the craniocervical posture measured by the positioning of the hyoid bone, head rotation, and the extension/flexion of the head (p > 0.05).
CONCLUSION
It can be concluded, therefore, that no relationship exists between cervical posture in the sagittal plane and TMD.
目的
通过头部侧位X线片测量矢状面颞下颌关节紊乱病（TMD）与颅颈姿势之间的关系。
方法
样本由从北里奥格兰德联邦大学随机选取的80名牙科专业学生组成。采用TMD研究诊断标准（RDC/TMD）评估TMD的体征和症状。利用每个个体的头部侧位X线片测量舌骨位置、颅颈角和枕骨-寰椎距离。采用卡方检验评估颅颈姿势测量指标与TMD之间的关系。
结果
未发现TMD与通过舌骨位置、头部旋转以及头部屈伸测量的颅颈姿势之间存在关联（p>0.05）。
结论
因此，可以得出结论，矢状面颈椎姿势与TMD之间不存在关联。
