EFFECTIVENESS OF LOW-LEVEL LASER THERAPY IN THE TREATMENT OF INFERIOR ALVEOLAR NERVE PARESTHESIA IN ORAL SURGERY: LITERATURE REVIEW

Abstract

Inferior alveolar nerve paresthesia is a neurosensory complication associated with oral surgical procedures, such as third molar extractions and dental implant placement, potentially affecting patients’ quality of life. In this context, low-level laser therapy has been investigated as a therapeutic alternative due to its potential to promote neural regeneration, modulate inflammation, and reduce symptoms. This study aimed to critically analyze the clinical evidence regarding the effectiveness of low-level laser therapy in treating inferior alveolar nerve paresthesia. This is an integrative literature review conducted through searches in PubMed, LILACS, and the Virtual Health Library (BVS), including studies published between 2019 and 2026 in Portuguese, English, and Spanish. Eligible studies included clinical trials, interventional studies, and randomized double-blind trials. The initial search identified 45 studies, of which 16 were included after applying eligibility criteria. The findings indicate favorable outcomes in neurosensory recovery, with improved sensitivity and reduced symptoms. However, heterogeneity was observed in treatment protocols, particularly regarding wavelength, energy density, power, and number of sessions. It is concluded that photobiomodulation is promising; however, standardized protocols and further studies are needed.
