Completed

• Conditions: TMJ Disc Disorder
• Interventions: Diagnostic Test: MRI

• Registration Number: NCT04951895
• Lead Sponsor: Al-Azhar University

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.

Arm && Interventions

Group	Intervention	Description
control group	MRI	patients with normal TMJ
Study group	MRI	Patients with TMJ internal deragement

Primary Outcome Measures

Name	Time	Method
VAS	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	baseline (pre treatment)	maximum nonassisted (voluntary) mouth opening (MVMO) in millimetres

Secondary Outcome Measures

Name	Time	Method
joint sound	baseline (pre treatment)	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.
