Al-Azhar University900 enrolled

Overview

the study aimed to evaluate the clinical and MRI finding of TMJ AND LPM with predication of the risk factors. Study design: this retrospective study included 1365 joints in 800 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.

Inclusion Criteria: \- study included 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.

Outcomes

Primary Outcomes

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.

Time frame: baseline (pre treatment)

mouth opening

maximum nonassisted (voluntary) mouth opening (MVMO) in millimetres

Time frame: baseline (pre treatment)

Secondary Outcomes

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.

Time frame: baseline (pre treatment)
