Effect of laser therapy in periodontal surgeries: a systematic review

Photodynamic therapy in periodontics is used to obtain antimicrobial effects and also to assist in the healing process by acting on tissue healing and regeneration after performing surgical procedures. The objective of this systematic review was to evaluate in the scientific literature the effectiveness of using laser therapy in the surgical approach of periodontal procedures. A systematic review of the literature was performed using the Scopus, Science Direct, Embase, Cochrane Collaboration Library, and PubMed/ MEDLINE databases. Studies on the use of laser therapy in periodontal surgical procedures were selected. The search strategy provided a total of 365 studies. After selection, ten articles met all the inclusion criteria and were included in this systematic review. Studies have shown that the use of laser therapy is an excellent approach to promote tissue repair, analgesia and antimicrobial activity in periodontal tissues. The use of LLLI associated with periodontal surgical treatment has proved to be promising and in the near future, new protocols are expected to emerge that can provide excellent treatments for patients who undergo periodontal surgery.
