Abstract

The purpose of this study was to report the application of antimicrobial photodynamic therapy (aPDT) via sinus tract associated with laser phototherapy (LPT) in conservative treatment of a late failure of endodontic retreatment in two clinical cases of post-treatment apical periodontitis. Post-treatment apical periodontitis is a microbiological matter, because infection is present in almost all cases associated with this condition, even in teeth with apparently adequate root canal treatments. Infection is usually located within the root canal system, but in a few cases it may spread to the periradicular tissues. Many biofilms are susceptible to aPDT, particularly in dental disease. In the present two cases reports, aPDT was applied via sinus tract. In the two clinical cases, endodontic retreatment was unsuccessful, with the presence of a persistent swelling sinus tract, despite the standard quality of the endodontic retreatment. Before any surgical intervention, a noninvasive aPDT via sinus tract was performed. The photosensitizer methylene blue (0.01%) was inserted through the entrance of the sinus tract. Laser irradiation was performed perpendicularly (660 nm, 40 mW, 90 J/cm(2), 63 sec/point) directly over the entrance of the...Continue Reading
