title: Endodontic failure--a problem from top to bottom.
abstract: Endodontically treated teeth are susceptible to bacterial contamination through exposure to oral fluids. It is crucial, therefore, that restorations placed during and after root canal therapy protect the root canal from oral contamination. This paper highlights the clinical steps necessary to reduce the risk of contamination in root-filled teeth.
