Abstract

Introduction: Antimicrobial effect of photodynamic therapy (PDT) and MTAD in association with endodontic therapy was shown in this study.

Methods: Thirty anterior teeth from patients were selected. Microbiological samples were taken Group 1 after endodontic therapy and irrigation with 5.23% NaOCL (Control group), Group 2 endodontic therapy and irrigation with MTAD, and Group 3 after PDT. After the three samples were collected, the root canal was filled with Calcium hydroxide, and after 1 week, a second session of the therapies was performed.

Results: PDT used Methylene blue (MB) dye as a photo-sensitizer and a diode laser as a light source. The samples collected after endodontic therapy in combination with         MTAD showed decreased bacterial load, whereas the combination of endodontic therapy with PDT showed remarkable decrease in the bacterial load.

Conclusion: The use of Methylene blue dye as a photo-sensitizer in PDT along with endodontic treatment leads to an enhanced decrease of bacterial load and may be an appropriate approach for the treatment of root canal.
