Effectiveness of low-level laser therapy in accelerating orthoontic tooth movement in maxillary anterior crowding- a randomized control trial

Abstract

Introduction: Orthodontic treatment plays a pivotal role in achieving functional and aesthetic dental alignment. However, prolonged treatment duration and associated discomfort remain significant concerns. Recent advancements in non-invasive techniques, particularly low-level laser therapy (LLLT), have shown promise in accelerating orthodontic tooth movement (OTM). LLLT is believed to enhance cellular activity, stimulate osteoclastic and osteoblastic functions, and reduce treatment time. While previous research has examined LLLT's efficacy, variations in laser parameters and irradiation protocols necessitate further investigation. This study aims to evaluate the effectiveness of LLLT in accelerating OTM during the initial levelling and alignment phase in patients with maxillary anterior crowding.
