Photodynamic Therapy: A Novel Ally for Surgical Endodontic Treatment? Case Report

Abstract

Introduction: Photodynamic therapy (PDT) has emerged as a powerful tool for conventional endodontic 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.

Antimicrobial Photodynamic Therapy in the Endodontic Treatment of Deciduous Teeth: In Vivo Pilot Study

“…Most studies are done on permanent teeth [1]. Generally, aPDT therapy is considered a possible alternative to assist in the eradication of bacteria in root canals [16][17][18][19].…”

B.P.F.C.® Bio-Plasma® with Pure Growth Factors (BioPlasma®) Used for the Treatment of a Persistent Great Periapical Lesion of an Endodontically Treated Tooth: A New Therapeutic Option

“…To improve the speed of healing of endodontic lesions, reduce postoperative symptoms, and improve bone quality, several researchers have tried to combine devices such as laser and photodynamic therapy with endodontic surgery, obtaining good results. However, there are still too few studies on these fascinating principals [ 11 , 12 ].…”
