December 1, 2023 updated by: Nourhan M.Aly

Role of Liquid Phase Concentrated Growth Factors vs. Hypertonic Dextrose Prolotherapy for Management of Patients With Disc Displacement Without Reduction (A Randomized Clinical Trial)

Purpose of the study is to compare clinically, radiographically and biochemically the effect of intra- articular injection of hypertonic dextrose with a stabilization appliance and the intra- articular injection of 2 ml of liquid phase concentrated growth factor with a stabilization appliance as a prolotherapy for temporomandibular joint anterior disc displacement without reduction.

Study Overview

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.

Detailed Description

Twenty four patients with anterior disc displacement without reduction will be selected from those attending the Prosthodontic Department, Faculty of Dentistry, Alexandria University and diagnosed clinically and by magnetic resonance imaging. Patients will be randomly assigned into 2 study groups each comprising 12 patients. Group I will receive an intra-articular injection of hypertonic dextrose in conjugation with a maxillary CAD/CAM full-arch hard clear acrylic stabilization appliance while group II will receive an intra-articular injection of LPCGF in conjugation with a maxillary CAD/CAM full-arch hard clear acrylic stabilization appliance.

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

Description

Inclusion Criteria:

  • Patients with painful TMJ.
  • Patients with limited mouth opening (MMO <40mm).
  • Patients with anterior disc displacement without reduction confirmed by MRI.
  • Presence of full or nearly full complement of natural teeth.
  • Patients with angle class I occlusion.
  • Patients with RCP not greater than 2mm and with no open bite.

Exclusion Criteria:

  • Patients who have anterior disc dislocation with reduction detected by MRI.
  • Inability or unwillingness to undergo magnetic resonance imaging (MRI) such as implanted electronic devices.
  • Patients having uncontrolled systemic disease, hematologic or neurologic disorders or inflammatory diseases.
  • Patients under anticoagulant drug therapy.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Hypertonic Dextrose Solution
Drug: Hypertonic Dextrose Solution
Patients in this group will receive an intra-articular injection of 12.5% hypertonic dextrose solution, once every month for three consecutive months, in conjugation with a maxillary CAD/CAM full-arch hard clear acrylic stabilization appliance.The point of needle entry will be 1 cm below the apex of the zygomatic arch and guided by ultrasound to ensure intra-articular injection in the superior joint space.
Active Comparator: Liquid Phase Concentrated Growth Factor (LPCGFs)
Biological: Liquid Phase Concentrated Growth Factor (LPCGFs)
Patients in this group will receive single intra-articular injection of LPCGF in conjugation with a maxillary CAD/CAM full-arch hard clear acrylic stabilization appliance.

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
Maximum mouth opening
Time Frame: up to 6 months
This will be evaluated using Helkimo Anamnestic index (Ai) which comprises the following classes: Ai0 - absence of subjective symptoms of dysfunction; AiI -mild symptoms, such as TMJ sounds, including clicking and crepitation, and feelings of stiffness or fatigue of the jaws; and AiII - severe symptoms of dysfunction, such as difficulty in opening the mouth wide, locking, luxations, pain on movement, and facial and jaw pain.
up to 6 months
Disc-condyle relationship
Time Frame: 6 months
This will be evaluated using magnetic resonance imaging (MRI) to assess the position of the articular disc and the condyle and the mandibular fossa
6 months
Myeloperoxidase enzyme activity
Time Frame: 6 months
This will be evaluated by using Myeloperoxidase enzyme assay kits for detection and quantitation of myeloperoxidase activity levels.
