Comparing Dextrose Prolotherapy vs. Sodium Hyaluronic Acid Injections for Jaw Joint Internal Derangement

This is a randomized comparative study to evaluate the effectiveness of two intra-articular injections for the management of Temporomandibular Joint (TMJ) internal derangement. The study compares Dextrose Prolotherapy (12.5%) versus Sodium Hyaluronic Acid. Sixty patients (30 per group) with clinically diagnosed TMJ internal derangement (Wilkes Stage II or III) who have not responded to conservative treatment will be enrolled. Participants will be randomly assigned to receive either a single 1ml intra-articular injection of Dextrose or Sodium Hyaluronic Acid into the superior joint space. The primary outcomes are the mean change in pain intensity (measured on a Visual Analogue Scale) and Maximum Inter-Incisal Opening (measured in millimeters) at baseline, 1 month, and 3 months post-injection.

Efficacy of Intra-Articular Hyaluronic Acid Combination Injections for Temporomandibular Joint Internal Derangement: A Clinical and MRI Based Randomized Trial

This randomized controlled clinical trial aims to compare the clinical and magnetic resonance imaging (MRI) outcomes of three intra-articular injection protocols for the treatment of temporomandibular joint (TMJ) internal derangement with reduction. Sixty patients who remain symptomatic despite conservative therapy will be randomly assigned to receive hyaluronic acid combined with platelet-rich plasma (PRP), tenoxicam, or corticosteroid. Clinical outcomes including pain intensity, maximum mouth opening, and joint clicking, together with MRI findings, will be evaluated over a 6-month follow-up period.

Arthrocentesis-PRF Versus Botulinum Toxin for Management of ADDwR

Temporomandibular joint (TMJ) internal derangement is a common cause of temporomandibular disorders and is often associated with pain, restricted mandibular movement, joint sounds, and functional limitations during mastication and mouth opening. Various treatment modalities have been proposed to manage these symptoms, aiming to reduce pain and improve joint function. This randomized clinical study was conducted to compare the effectiveness of botulinum toxin type A (BOTOX) injection into the lateral pterygoid muscle versus intracapsular injection of injectable platelet-rich fibrin (I-PRF) in the management of TMJ internal derangement. A total of 20 patients diagnosed with TMJ internal derangement were randomly allocated into two equal groups. Group I received intracapsular I-PRF injections into the superior joint space of the temporomandibular joint, while group II received botulinum toxin injections into the lateral pterygoid muscle. Clinical evaluation was performed using subjective and objective parameters at one, three, and six months following treatment. Outcomes included assessment of pain, maximum mouth opening, mandibular movements, joint tenderness, and muscle tenderness upon palpation. Radiographic evaluation was conducted using magnetic resonance imaging (MRI) to assess intra-articular changes of the temporomandibular joint following the interventions. The study aimed to determine which treatment modality provided superior clinical and radiographic outcomes for the management of TMJ internal derangement.

Clinical Effectiveness of Combined Arthrocentesis With Intra-articular Injection of Meloxicam in Treatment of Temporomandibular Joint Internal Derangement

This randomized controlled clinical study is designed to evaluate the clinical effectiveness of combining temporomandibular joint (TMJ) arthrocentesis with a single intra-articular injection of meloxicam in patients suffering from TMJ internal derangement. Temporomandibular disorders (TMD) are common conditions causing pain, restricted jaw movement, and joint sounds, which can significantly impair patients' quality of life. While conventional treatments include conservative approaches and arthrocentesis alone, finding optimal therapeutic protocols remains crucial for refractory cases. A total of 50 adult patients diagnosed with unilateral TMJ internal derangement (with or without reduction) who have failed at least one month of conservative therapy will be enrolled and randomly allocated into two equal groups: Study Group: Will undergo joint arthrocentesis followed by a single intra-articular injection of meloxicam (15 mg / 1.5 mL). Control Group: Will undergo joint arthrocentesis alone using Ringer's lactate solution. Patients will be evaluated across a 12-week postoperative period (at 2, 4, 8, and 12 weeks) to assess primary and secondary outcomes, including pain intensity (measured via a Numerical Rating Scale), maximum mouth opening (inter-incisal distance in millimeters), joint sounds (clicking, popping, or crepitus), and overall patient satisfaction. The findings aim to establish whether adding an intra-articular non-steroidal anti-inflammatory drug (NSAID) enhances the therapeutic benefits of standard TMJ arthrocentesis.

Efficacy of Injectable PRF in Management of TMJ Internal Derangement

This study evaluated the efficacy of injectable platelet-rich fibrin both clinically and using MRI in management of temporomandibular joint internal derangement

Intra-Articular PRP Versus Dexamethasone for TMJ Internal Derangement

This study looked at whether an injection into the jaw joint (temporomandibular joint, or TMJ) can help people who have pain, clicking, and difficulty opening their mouth due to a slipped joint disc. Thirty patients were randomly assigned to receive one of three injections: platelet-rich plasma (PRP, made from the patient's own blood), a steroid medication (dexamethasone) with a local anesthetic, or a saline (salt water) injection as a comparison. Pain, joint clicking, and mouth opening were measured before the injection and one week later. The study found that both PRP and the steroid injection reduced pain and clicking more than saline, and PRP also improved how wide patients could open their mouth.

A Prospective Randomized Clinical Trial Comparing a Fast-Fix-Enhanced Arthroscopic System Versus Conventional Arthroscopic Suturing for Temporomandibular Disc Repositioning in Internal Derangement: Functional, Clinical, and Surgical Outcomes

This prospective randomized clinical trial evaluates the effectiveness of a Fast Fix-enhanced arthroscopic system compared with conventional arthroscopic suturing for temporomandibular joint disc repositioning in patients with TMJ internal derangement. Patients are randomly allocated into two groups and assessed for functional improvement (maximum mouth opening), pain reduction, joint symptoms, and surgical performance outcomes over a 6-month follow-up period. The study aims to determine whether the Fast Fix-enhanced technique provides superior clinical, functional, and surgical outcomes compared to conventional arthroscopic suturing

Effect of Intraarticular Injection of Tenoxicam and Hyaluronic Acid Versus Platelet-Rich Plasma and Hyaluronic Acid in Temporomandibular Joint Internal Derangement

To compare the effect of intraarticular injection of Tenoxicam and Hyaluronic acid Versus Platelet-rich plasma and Hyaluronic acid in the management of patients with TMJ internal derangement with reduction.
