Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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)
Primary	mouth opening	maximum nonassisted (voluntary) mouth opening (MVMO) in millimetres	baseline (pre treatment)
Secondary	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)
