Abstract

Background

Degenerative joint disease (DJD) can be associated with disc displacement (DD) in temporomandibular disorder (TMD) patients. However, the relationship between different types of DDs and DJD remains unclear.

Objectives

To investigate the odds ratios of different types of sagittal and coronal DDs confirmed by magnetic resonance imaging (MRI) and DJD confirmed by cone-beam computed tomography (CBCT) in TMD patients.

Methods

Radiographic data from 69 males and 232 females were collected for analysis. CBCT was used to diagnose DJD, with criteria including erosion, osteophytes, generalized sclerosis, and cysts in the joint. Eight types of DDs were evaluated by sagittal and coronal MRIs: NA, no abnormality; SW, sideways; ADDR, anterior with reduction; ADDR+SW; ADDNR, anterior without reduction; ADDNR+SW; single SW; PDD, posterior; PDD+SW. The odds ratios of DJD in joints with different types of DDs were determined after joint correlation, age, and gender adjustment.

Results

Compared with NA, the odds ratio of DJD in ADDR was 2.397 (95% CI [confidence interval]: 1.070-5.368), ADDR+SW was 4.808 (95% CI: 1.709-3.528), ADDNR was 29.982 (95% CI: 15.512-57.950), and ADDNR+SW was 25.974 (95% CI: 12.743-52.945). Erosion was significantly increased in ADDR, ADDR+SW, ADDNR and ADDNR+SW; osteophytes were significantly increased in ADDR+SW, ADDNR and ADDNR+SW; and generalized sclerosis and cysts were significantly increased in ADDNR and ADDNR+SW. There were no significant associations between single SW, PDD, PDD+SW and DJD.

Conclusions

ADDR, ADDR+SW, ADDNR, and ADDNR+SW were associated with DJD. ADDNR had a significantly higher prevalence of DJD than ADDR. There were no significant relationships between single SW, PDD, PDD+SW and DJD.
