New Trend of LLLT (Low Level Laser Therapy)

Abstract

Low level laser therapy (LLLT) is gaining popularity in a variety of clinical applications. The lasers used in dental applications for LLLT are such as the He–Ne laser, the semiconductor laser and others. Low level laser light is reported to alleviate pain and trigeminal nerve paresthesia, to accelerate wound healing, to have a positive effect on inflammatory processes, the prevention and treatment of radiotherapy-induced oral mucositis in oral cancer. However, the biochemical reactions by low level laser irradiation are not fully understood. This paper presents the efficacy of LLLT and cautions when applying clinical in use.
