Impact Of Low-Level Laser Therapy On Gag Reflex Reduction In Prosthodontic Patients: An In-Vivo Study

Abstract

This study evaluates the effectiveness of low-level laser therapy (LLLT) in reducing the gag reflex during dental procedures, specifically in prosthodontic patients. The gag reflex is a common challenge in dentistry, particularly during impression making, which can hinder successful treatment. This study focused on the stimulation of the PC6 acupressure point using LLLT to alleviate this reflex. A total of 13 patients were included, with each patient undergoing two impression procedures: one with no stimulation and another after LLLT applied to the PC6 point. Gag reflex severity was assessed using the Dickinson and Fiske Gagging Severity Index (GSI). Results showed a significant reduction in gag reflex severity following LLLT stimulation of the PC6 point, suggesting that LLLT could be a viable, non-invasive treatment for managing the gag reflex in prosthodontic procedures. The findings provide promising evidence for LLLT as an effective adjunct to traditional gag reflex management techniques in dental practice.
