Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 40 years (Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Temporomandibular joint dysfunction
Time Frame: 3 months
Using Helkimo Anamnestic Index that includes 5 items, each having 3 possible answers scored 0, 1 or 5. The 1st item assesses limitations in range of jaw movement & is divided to 4 sections: maximum mouth opening, protrusion & lateral shift. For mouth opening , value of >40mm scores 0, 30-39mm scores 1 & <30mm scores 5. Protrusion & lateral shifts score 0 if the measurement is ≥7mm, 1 if ranging between 4-6mm and 5 if it is <4mm. These sections are added together to get a total that scores 0 if the sum of the 4 sections is 0, 1 if the subtotal is between 1-4 & 5 if the subtotal is >4. The 2nd item evaluates joint alterations that produce deviations, sounds and joint locks. The 3rd item evaluates pain when performing movements. The 4th item evaluates masticatory muscles pain. The 5th item evaluates pain on palpation in the prearticular area of TMJ. The 5 items are added and scored; 0: no TMJ involvement, 1-9: mild involvement, 10-19: moderate involvement & 20-25: severe involvement
3 months
Pain level
Time Frame: 3 months
This will be assessed using the visual analogue scale (VAS) with score ranges from 0 (lowest) to 10 (highest). Higher scores indicate greater pain levels.
3 months
Temporomandibular joint clinical evaluation
Time Frame: 3 months
Magnetic Resonance Imaging (MRI) will be performed for all patients using a 3 Tesla MRI scanner with a head coil. Gradient T2 (T2*) and proton-density (PD) weighted spin echo (SE) sequences will be carried out in closed and open mouth positions in the oblique sagittal plane. MRI is considered the gold standard (objective) in imaging the soft tissue components of the TMJ.
