Study population: The retrospective 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. The sample originally included patients who provided consent to participate in this study and who ultimately underwent treatment for TMJD between 2008 and 2019.
Who may be able to join
- 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.
Who cannot join
- 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.

About this study
Official title: Correlation Between Types of Lateral Pterygoid Muscle Attachment, Type of Disk Displacement and Osteoarthritic Changes of the Temporomandibular Joint
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
MRIDiagnostic test
MRI of TMJ
| Study group | Role | What they receive |
|---|---|---|
| control group | NORMAL TMJ Receives: Diagnostic Test: MRI | |
| Study group | Patients with TMJ internal derangement Receives: Diagnostic Test: MRI |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: baseline (pre treatment)
mouth opening
maximum nonassisted (voluntary) mouth opening (MVMO) in millimetres
Measured: baseline (pre treatment)
Secondary outcomes (1)
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.
Measured: baseline (pre treatment)

Questions about this trial
What is this clinical trial studying?
An observational study of TMJ Disorder, run by Al-Azhar University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
VAS (time frame: baseline (pre treatment)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jul 2021.
