Clinical and MRI Finding of The Temporomandibular Joint Stuck Disk

Study Overview
=================
Brief Summary
-----------------
the study aimed to evaluate the clinical and MRI finding of TMJ with stuck disk with predication of the risk factors

Detailed Description
-----------------
the study aimed to evaluate the clinical and MRI finding of TMJ with stuck disk 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.

Official Title
-----------------
Clinical and MRI Finding of The Temporomandibular Joint Stuck Disk

Conditions
-----------------
TMJ Disc Disorder

Intervention / Treatment
-----------------
* Diagnostic Test: MRI


Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: patients seeking treatment for TMD at Al-Azhar University Hospital and the outpatient clinic at the Faculty of Dental Medicine of Al-Azahr University. Exclusion Criteria: Exclusion Inclusion criteria: 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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| VAS | 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. | baseline (pre treatment) | 
| MOUTH OPENING | maximum nonassisted (voluntary) mouth opening (MVMO) in millimetres. | baseline (pre treatment) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| JOINT SOUND | and the joint sound was then determined by combining 3 means: (1) palpation of the TMJ zone by the clinician, (2) the patient's self-reporting regarding whether the joint sound could be heard, and (3) auscultation of the TMJ zone with the stethoscope. | baseline (pre treatment) |
