Magnesium Sulfate After TMJ Arthrocentesis

Temporomandibular joint (TMJ) arthrocentesis is a well-established minimally invasive treatment for patients with TMJ arthralgia and internal derangement. Although intra-articular hyaluronic acid is frequently administered following arthrocentesis to improve pain relief and joint function, evidence regarding the efficacy of intra-articular magnesium sulfate remains limited. Magnesium sulfate has demonstrated analgesic and anti-inflammatory properties through N-methyl-D-aspartate (NMDA) receptor antagonism and modulation of calcium influx; however, its clinical use in TMJ disorders has not been adequately investigated. This investigator-initiated, single-center, three-arm randomized controlled pilot trial was conducted to compare the clinical effectiveness and safety of intra-articular magnesium sulfate, hyaluronic acid, and normal saline administered after TMJ arthrocentesis in patients diagnosed with TMJ arthralgia according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). The primary outcome was the change in chewing pain measured using the Visual Analog Scale (VAS) at 4 weeks. Secondary outcomes included maximum mouth opening, Jaw Functional Limitation Scale-8 (JFLS-8), Oral Health Impact Profile-14 (OHIP-14), Graded Chronic Pain Scale version 2.0 (GCPS v2.0), Patient Health Questionnaire-4 (PHQ-4), analgesic consumption, and adverse events.

TMJ Arthroscopy Compared to Arthrocentesis in Disc Displacement Without Reduction

The goal of this clinical trial is to compare the intervention arthroscopic lysis and lavage to the intervention arthrocentesis in treating disabling and painful temporomandibular joint disc displacement without reduction. The main questions it aims to answer are: * Which surgical method that best improves mouth opening capacity, TMJ pain, and TMJ disability? * If any pre- or peri-operative variable/-s could be identified as a predictor for surgical outcome? Researchers will compare arthroscopic lysis and lavage to arthrocentesis to see if arthroscopic lysis and lavage works better to treat temporomandibular joint disc displacement. Participants will: * Have one of the two interventions under general anesthesia, not knowing which intervention. * Visit an external clinic for regular checkups at 1, 3, 6, 12, and 24 months after surgery. * Answer three different quality of life surveys at the checkups.
