Abstract
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 periodontitis
in a mandibular incisor submitted to surgical endodontic treatment associated with PDT. After
conventional procedures, photosensitizer methylene blue (0.01%) was applied to the retrograde
cavity for 3 minutes, followed by irradiation with diode laser (100 mW and 660 nm) for 3
minutes. Six months after the procedure, the patient was asymptomatic, and the radiographic
examination showed healthy periradicular tissues.
Conclusion: The association of PDT with surgical endodontic treatment was effective, suggesting
that this therapy may provide additional benefits to patients when compared to the conventional
surgical technique.
