Effectiveness of low-level Diode laser therapy in recurrent aphthous stomatitis treatment at Can Tho University of Medicine And Pharmacy Hospital in 2020-2022

Abstract

Background: Recurrent aphthous stomatitis (RAS) are the most common oral ulceration in lesions of the oral mucosa. Treatment aims to reduce pain and healing time. Low-level Diode laser therapy can relieve pain, anti-inflammatory, reduce edema, stimulate cell biology, and stimulate healing. Low-level Diode laser therapy is an alternative therapy to conventional drug use, promising to help improve the quality of life, improve the patient's quality of life and avoid complications caused by long-term drug use. Objectives: To evaluate the therapeutic effect of a low-level Diode laser on RAS treatment to reduce pain, size of ulcers, and healing time. Materials and methods: A clinical study was conducted on 30 patients who presented RAS lesions were treated with low-level laser therapy. The patients were evaluated for the size, position, pain score, form of ulcers, healing time before and immediately, fourth and sixth day after treatment. The data was analyzed using SPSS 20. Results: The VAS score pre-treatment was 4.33±1.65, immediately post-treatment was 1.20±1.06. The size of ulcers pre-treatment was 4.58±2.35mm, and post-treatment fourth day was 2.47±2.30mm. The healing time was 5.04±0.32 days. Conclusion: Low-level Diode laser therapy is effective in RAS treatment to reduce pain, size of ulcers, and healing time.
