Uso do laser de baixa potência para tratamento de casos de hipossialia e xerostomia: revisão de literatura

Abstract

INTRODUCTION: Xerostomia and hyposalivation, which affect the quality and quantity of saliva production, are clinically diagnosed through anamnesis and metric exams and can be associated with pharmacological, pathological, and lifestyle factors. Current treatment options include therapeutic approaches such as saliva substitutes and low-level laser therapy (LLLT), which stimulates salivary flow. OBJECTIVES: To evaluate the use of low-level laser therapy to improve the symptoms of xerostomia and hyposalivation. The specific objectives include investigating its indications and contraindications in the management of this pathology. METHODOLOGY: Using health databases and including epidemiological or qualitative studies published in the last 10 years on the use of low-level laser therapy in this context. RESULTS: This review study provides insights into the current use of low-level laser therapy in the treatment of xerostomia and hyposalivation, based on available scientific evidence. The results indicate improvements in symptoms and saliva production with LLLT, as suggested by previous indications. These findings highlight the potential efficacy of this therapeutic approach for patients with these conditions, providing an updated perspective on the clinical benefits of low-level laser therapy. FINAL CONSIDERATIONS: Although there are positive results in the use of low-level laser therapy for hyposalivation and xerostomia, additional studies are needed to confirm its efficacy in treating these conditions.
