Abstract
Pulpal and periapical pathosis are biofilm-induced infections. Understanding the complex nature of endodontic biofilm would help to create a new disinfection strategy to eliminate the microorganism from the root canal system. The intricate canal structure creates challenges for proper disinfection, necessitating the need to understand the biofilm structure, composition, and mechanism within the biofilm community. This paper describes the endodontic biofilm structure, formation of biofilm, and advanced therapeutic options for combating the biofilm community within the root canal system.
