Abstract


The use of instruments, such as filees and reamers, to open the orifice and cleaning-shaping procedure, in a curved canal in excess of 20-degree angle without preserving instrument and irrigation may form a ledge in the canal. Treatment failure may result due to an inadequate cleaning at the apical third of the canal. This failure may be prevented by eliminationg the ledge - correction of the curved canals. The purpose of this case is to highlight the importance of careful use of endodontic instruments to avoid ledging. Therefore knowledge of tooth morphology and the use of files, in curved canals, is an important factor.
