The main goal of endodontic treatment is to remove necrotic tissue and microorganisms from root canals by means of mechanical preparation and disinfection in order to seal the root canal space and to prevent subsequent recontamination. According to the literature, the success of primary endodontic treatment reaches values from 47-97% [33]. Failures of orthograde root canal fillings occur in cases with pre-operative presence of periapical radiolucency, root canal filling with voids or root canal fillings more than 2 mm short of the radiographic apex and inadequate coronal restoration [34]. If microorganisms remain present in the root canal system or invade the periradicular tissues or periradicular tissues become contaminated with root canal filling materials, inflammatory and immune response or foreign body reaction may occur, causing local bone destruction and impairment of tissue healing. Failures in endodontic treatment can be managed by ...
