Introduction: Photodynamic therapy (PDT) has emerged as a powerful tool for conventionalendodontic treatment, capable of eradicating microorganisms present in endodontic infections.Despite this, the use of PDT in the surgical endodontic treatment is not well-known.Case Report: This paper describes the case of a patient with asymptomatic apical periodontitisin a mandibular incisor submitted to surgical endodontic treatment associated with PDT. Afterconventional procedures, photosensitizer methylene blue (0.01%) was applied to the retrogradecavity for 3 minutes, followed by irradiation with diode laser (100 mW and 660 nm) for 3minutes. Six months after the procedure, the patient was asymptomatic, and the radiographicexamination showed healthy periradicular tissues.Conclusion: The association of PDT with surgical endodontic treatment was effective, suggestingthat this therapy may provide additional benefits to patients when compared to the conventionalsurgical technique.
