EVALUATION OF THE EFFECTS OF LASER THERAPY DURING AND AFTER PERIODONTAL PROCEDURES

Abstract

The laser is a powerful source of light energy that stands out for its versatility and applications in various scientific fields, including dentistry. In routine periodontal practice, laser therapy has multiple applications. high-power lasers, for example, can be used in procedures such as scaling and root planing, frenectomy, and clinical crown lengthening surgery, reducing discomfort and pain during the postoperative period. while low-level laser therapy (LLLT) offers strong anti-inflammatory, analgesic, and healing effects, in addition to biologically modulating tissues. Additionally, when combined with photosensitive substances, the laser also acts as photodynamic therapy, and can even combat infections. The objective of this study was to conduct a literature review to relate the use of lasers during and after periodontal procedures to their respective outcomes. Therefore, this study was designed as an integrative literature review guided by the following question: how can the use of laser therapy contribute to tissue healing during and after periodontal procedures, and what insights do studies on this topic offer to the dental community? To answer this question, searches were conducted in the SCIELO, PubMed, and Google Scholar databases, as these contain the majority of publications in the health field. Scientific articles published in Portuguese and English between 2010 and 2025 were included, provided they addressed patient safety and well-being and employed different methodological approaches. Analysis of the studies indicated that laser therapy, when used as an adjunct to periodontal treatments, proved to be an efficient and promising complementary tool.
