Antimicrobial Photodynamic Therapy in Endodontic Treatments

Insufficient root canal disinfection is one of the main reasons for persistent periapical pathology. Antibacterial Photodynamic Therapy (aPDT) and calcium hydroxide therapy as auxiliary adjunct methods for common endodontic retreatments displays disinfectant properties. Efficacy against E.faecalis is better in LED photodynamic therapy compared to calcium hydroxide therapy. APDT is capable of disinfecting the canals in a single visit root canal treatment. This results in a fewer number of visits and less chair time. Advantages of aPDT with LED over lasers include greater effectiveness due to a broader spectrum, ease and safety of use, affordability and less heat production.
