Abstract & Key Insights

• • Background:
    • Temporomandibular Disorders (TMD) are frequently associated with psychological comorbidities, specifically anxiety and sleep disorders.
    • While traditional auriculotherapy involves needles or pressure seeds, this study explored the use of Photobiomodulation (PBM)—low-level laser therapy—as a painless, non-invasive alternative.
    • The goal was to determine if stimulating specific ear points with laser light could alleviate the anxiety and sleep issues often seen in TMD patients.
  • Mechanism:
    • Neural Modulation: Laser light is applied to specific points on the auricle (outer ear), such as the Shenmen and Sympathetic points.
    • Vagus Nerve Stimulation: The ear is richly supplied by the auricular branch of the vagus nerve. PBM is thought to stimulate these nerve fibers, which modulates the autonomic nervous system.
    • Biochemical Response: This process triggers the release of neurotransmitters like serotonin and endorphins, which have systemic calming and anti-anxiety effects.
• • Conclusion:
    • Photobiomodulation (PBM) applied to auriculotherapy points is a highly effective and safe non-invasive tool for treating anxiety.
    • While its direct impact on sleep and physical jaw pain requires further investigation with different parameters, its success in emotional regulation makes it a valuable adjunctive therapy for the comprehensive management of TMD.
