To determine the diagnostic accuracy, sensitivity, and specificity of magnetic resonance (MR) imaging of the temporomandibular joint (TMJ) in the assessment of disk position, disk form, and changes in the osseous components, 55 fresh cadaver joints were imaged. A 1.5-T imager was used in the sagittal and coronal planes. After MR imaging, the joints were(More)
The purposes of this study were to develop a classification system for disk displacement in the temporomandibular joint (TMJ) and to study the prevalence of the various types of TMJ disk displacement in patients and symptom-free volunteers. The study was based on bilateral MRIs of 243 patients and 57 symptom-free volunteers. Eight different types of disk(More)
The purpose of this study was to measure interobserver and intraobserver variation in reporting magnetic resonance images of the temporomandibular joint. This study was based on magnetic resonance images of 149 joints. The images were interpreted independently by two of us on two occasions, 2 to 4 weeks apart. We were trained together before starting the(More)
The purpose of this study was to determine the value of axial images for diagnosis of disk displacement and osseous changes of the temporomandibular joint. Sagittal, coronal, and axial magnetic resonance images were obtained of 35 fresh temporomandibular joint autopsy specimens. The sagittal and coronal images were interpreted for position of the disk and(More)
The purpose of this autopsy study was to test the hypotheses that temporomandibular joint (TMJ) arthrosis is more common in women than in men, increases with age, and is more common in edentulous persons than in those with natural teeth. Two hundred forty-eight TMJs removed at autopsy from 224 fresh cadavers were investigated macroscopically with dissection(More)
OBJECTIVES There are considerable differences in individual health education programs for persons at high risk of type 2 diabetes between ordinary Japanese life-style modification programs and the Diabetes Prevention Program in the US, the former being relatively moderate and the latter more intensive. We therefore compared the effectiveness of intensive(More)
This study was undertaken to determine if it is possible to identify medial disc displacement with dual space anteroposterior (AP) arthrotomography. Contrast medium was injected into the upper and lower joint spaces of 11 fresh temporomandibular joint (TMJ) autopsy specimens and arthrotomograms were obtained with an AP projection. The arthrotomograms of(More)
The purpose of this investigation was to determine whether it is possible to diagnose medial and lateral disk displacements by single-contrast lower-compartment arthrography with an anteroposterior projection. Contrast medium was injected into the lower joint space of 29 fresh temporomandibular joint autopsy specimens. Anteroposterior arthrograms and(More)
