Periradicular interventions are among the most common in endodontic surgery. In cases where the apical third of the root canal can not be cleaned and filled in advance by the conventional anterograde method, the apical resection is finished by cavity preparation and retrograde filling placement. Amalgam usage as a retrograde filler results in many complications. The present article reports a similar clinical case. The disadvantages of amalgam were discussed. The new materials designed for root canal treatment should meet numerous requirements. Usage of new methods and materials could eliminate the need of apicoectomy and retrograde filling.
