Overview
Brief Summary
the study aimed to evaluate the clinical and MRI finding of TMJ with posterior disk displacement with predication of the risk factors
Detailed Description
: the study aimed to evaluate the clinical and MRI finding of TMJ with posterior disk displacement with predication of the risk factors. Study design: this retrospective study included patients diagnosed as TMJ internal derangement and all the patients examined by MRI from 2008 to 2019. Cases with loss of continuity of articular disk or the posterior attachment of the disk were considered as positive cases.

- •Patients were included if they were older than 18 years and diagnosed with TMJD. criteria for this study included systemic diseases (the presence of polyarthritis or other rheumatic diseases), contraindications for MRI (e.g., implanted metal or medical devices, claustrophobia), the presence of neurologic disorders, head and neck cancer, oral submucous fibrosis, a history of TMJ surgery, a history of previous nonsurgical treatment such as occlusal splints, and a history of joint injection with HA/PRP. Trauma patients with subcondylar fracture and patients with congenital and developmental disorders of the TMJ were also excluded from the study.
Outcomes
Primary Outcomes
VAS
Time Frame: baseline (pre treatment)
posttreatment pain index scores were measured using a 10-point visual analogue scale (VAS), with 0 indicating absence of pain and 10 indicating the worst pain.
mouth opening
Time Frame: baseline (pre treatment)
maximum nonassisted (voluntary) mouth opening (MVMO) in millimetres
Secondary Outcomes
- joint sound(baseline (pre treatment))
