Laser-Assisted Non-Surgical Treatments of Periodontitis

Abstract

This entry explores the innovative use of lasers in the non-surgical treatment of periodontitis, shedding light on the advantages, effectiveness, and limitations of this approach. There has been a massive eruption of innovations and technologies to assist in the treatment of periodontal diseases over the past 30 years. The use of lasers has opened new horizons and possibilities that can enhance periodontal treatments. However, their use is not always based on validated concepts and evidence-based protocols. Hence, this entry aims to describe, summarize, and assess the available evidence on the current laser-assisted protocols in the non-surgical treatment of periodontitis. Four distinct laser-assisted approaches are addressed: (1) the use of lasers for the removal of subgingival calculus, (2) the use of lasers in photodynamic therapy/photoactivated disinfection, (3) the use of lasers in photobiomodulation therapy, and (4) the use of high-power lasers. Based on the available studies and on the current guidelines and recommendations, the use of lasers exhibits several advantages, such as the increased disinfection of periodontal pockets and the junctional epithelium and connective tissue, the removal of calculus and biofilm, and the bactericidal effect on periodontal pathogens. Moreover, photobiomodulation therapy seems to play a positive role in the management of the inflammatory process of periodontitis. Although promising, the use of lasers in the non-surgical treatment of periodontitis needs to be further investigated.
