Evaluation of Antibacterial Efficacy of Photodynamic Therapy vs. 2.5% NaOCl against -infected Root Canals Using Real-time PCR Technique.

Background: Bacteria like can produce intra- and extra-radicular biofilms. Theoretically, the adjustable penetration ability of lasers enables better access to root canal system. Therefore the aim of the present study was to compare the ability of photoactivated laser and 2.
