2025 Catalog: All Courses

Root canal systems have complex anatomic and morphological features. These systems provide unique recesses for microorganisms to harbor in. Bacteria present in these unique recesses cause pulpal and/or peri-radicular disease to develop. Primary root canal infections are polymicrobial [10-30 bacterial species] and are dominated by obligate anaerobic bacteria [E. faecalis].
There are multiple obstacles in removing irritants from root canal systems. Such as: complexity of the root canal system, numerous dentinal tubules, invasion of tubules by microorganisms, formation of a smear layer. Successful outcome in endodontics require the elimination and reduction of irritants and prevention of recontamination of the root canal system.
