Myogenous and arthrogenous TMDs present distinct anatomical challenges, requiring targeted interventions. Key findings highlight the efficacy of conservative therapies, including behavioral interventions, physical therapies, and occlusal splints, as first-line treatments, followed by low-level laser therapy (LLLT), transcutaneous electrical nerve stimulation (TENS), and dry needling for myofascial pain.
