[Case Study] Low-Level Laser and Its Interface With Sleep Dentistry: Clinical Case Report

INTRODUCTION: This study aimed to evaluate and raise the therapeutic hypothesis of the use of low-level laser as a complementary therapy in patients with sleep disorder (SD) in a broad approach involving other pathologies superimposed on this pathology. METHODS: This is a clinical case report of a patient with Parkinson's disease (PD) complaining of sleep disorder. The proposed treatment is the use of photobiomodulation (FB) with intraoral application using an innovative dosimetry. SD was assessed using an adapted analogue scale. RESULTS: In the evaluation performed after the last session, there was an improvement in the sleep disorder compared to the pre-treatment evaluation. However, one month after the end of the treatment, it was observed that the quality of sleep remained practically the same. CONCLUSION: We can conclude that low-potency FB can be a modulator in the production of neurotransmitter substances in a local and systemic way, being a complementary or alternative treatment for patients with sleep disorder (SD).
