Abstract
The aim of a root end lling is to prevent irritants from the root canal from leaking into the periapical region and to improve the apical seal created by nonsurgical endodontic care. Various restorative materials that have been used for coronal restorations have been tried and tested as root end lling materials, as well as the creation of restorative materials designed specically for root end lling. In the past, amalgam was the preferred material for root end lling.
