Abstract
Background: Temporomandibular disorders (TMDs) are a group of conditions affecting the temporomandibular joint (TMJ) and associated muscles, leading to pain, restricted jaw movement, and impaired quality of life. Conventional treatments, including physical therapy, medications, and surgical interventions, have varying degrees of success and potential side effects. Cannabidiol (CBD), a non-psychoactive component of cannabis, has gained attention for its anti-inflammatory, analgesic, and anxiolytic properties. This study explores the potential role of CBD in TMD management. Methods: A review of existing literature was conducted (2007–2024), focusing on preclinical and clinical studies assessing the efficacy of CBD in pain modulation, inflammation reduction, and muscle relaxation. Relevant studies were sourced from PubMed, Scopus, and Web of Science databases. Additionally, potential mechanisms of action, including interactions with the endocannabinoid system, were analyzed. Results: Studies suggest that CBD exerts analgesic and anti-inflammatory effects by modulating CB1 and CB2 receptors, reducing cytokine release, and influencing neurotransmitter pathways. Preliminary clinical evidence indicates that CBD may alleviate TMD-related pain and muscle tension with minimal adverse effects. However, high-quality randomized controlled trials are limited. Conclusions: CBD demonstrates promise as a potential adjunctive treatment for TMD. Further research, including well-designed clinical trials, is necessary to establish its efficacy, optimal dosage, and long-term safety.
