The endodontic treatment aim at eliminating infections and reinfection prevention; however, sometimes re-treatment is necessary, and it can be complemented with paraendodontic surgery due to reinfection, which can also persist.\n                    <jats:italic toggle=\"yes\">Methods:<\/jats:italic>\n                    Our study group consisted of six clinical cases (endodontic treatment), with the introduction of a 300-\u00b5m optic fiber through the fistula channel, where three applications were carried out with an interval of 15 sec, each with a discharge of 300 mJ of energy and frequency of 30 Hz.\n                    <jats:italic toggle=\"yes\">Results:<\/jats:italic>\n                    After a 7-day interval, the signs and symptoms were absent, even after a follow-up of 18 months.
