CBCT characteristics and interpretation challenges of temporomandibular joint osteoarthritis in a hand osteoarthritis cohort.

CONCLUSIONS:: TMJ changes were common in elderly with hand OA and characterized by bone productive changes. The radiologic features indicated a late stage TMJ OA. Interpretation challenges related to subtle changes were identified and are reflected by the rather low observer agreement. The diagnosis of TMJ OA should be based on evident and clear abnormalities only. PMID: 30633546 [PubMed - as supplied by publisher]

In this study, 80 CBCT images of the temporomandibular joint (TMJ) pertaining 20 patients with osteoarthritis and 20 healthy individuals were evaluated, as well as the CBCT images that were obtained for other reasons. The images were reviewed in the coronal and sagittal sections. Considering the higher prevalence of osteoarthritis in women and after eliminating gender-based interventions, all the female patients were enrolled in the study. Chi-square was used to evaluate the correlations between the changes in the condylar head by the grouping of the patients, and the significance level was considered at 0.05. Results...

ConclusionsA large percentage of the scans showed a correlation between the presence/absence cervical spine osteoarthritis and TMJ osteoarthritis, but no relationship based on their degree of their severity. A larger sample size must be evaluated, as the next logical step, to further understand this relationship.

ConclusionPanoramic TMJ radiography demonstrated limited diagnostic accuracy and acceptable reliability in detecting bony lesions of the TMJ, although it was better than conventional panoramic radiography.

CONCLUSIONS The findings of this clinical and CBCT imaging study showed that sodium hyaluronate injection into the superior and inferior TMJ space in patients with osteoarthritis improved clinical symptoms, but did not control the progression of osteoarthritic joint destruction.

Bone scintigraphy has been used for the diagnosis of early-stage temporomandibular joint (TMJ) osteoarthritis (OA) owing to its high sensitivity. However, the diagnostic value of bone scintigraphy may be compromised when applied to patients in an age range with high bone metabolism rates. The aim of this study was to investigate the validity of bone scintigraphy as an appropriate diagnostic modality for TMJ OA. A total of 406 subjects (145 male, 261 female; age range 14 –87 years) were selected, and all subjects underwent both bone scintigraphy and computed tomography (CT).

ConclusionsOur results add to the existing preliminary knowledge regarding the osteoporotic changes that occur in the trabecular structure under the subchondral bone, which is normally not seen on radiographic images, as well as the destruction and remodeling that occur on the condyle surface, which is visible on radiographic images.
