REMOVAL OF A BROKEN PATHFILE: CASE REPORT

Broken root canal files are challenging complications in endodontics. Especially teeth with apical pathologies are more difficult to threat because of the must to establish an access to apex. Otherwise root canal system can’t be disinfected by irrigants or medicaments. In this case a #16.02 pathfile was broken in a tooth with acute apical periodontitis. After this complication, the broken instrument totally removed from the root canal system and the tooth treated by a multivisit aproach succesfully.
