Curved canal-mishap and management- a review

Amurdhavani and M G Aarthy

Aim: The aim of this review is to focus on mishaps related to curved root canal and its managing methods.
Background: Nature seldom draws a straight line. Nowhere is this more apparent than in the anatomy of teeth roots and root canal systems of human teeth.Canal shaping is a critical aspect of endodontic treatment because it influences the outcome of the subsequent phases of canal irrigation and filling and the success of the treatment itself. In fact, curved canals are the most common endodontic complexity.The most frequent problems occurring in canal preparation are root perforation, ledging and instrument separation.These problems usually occur as a result of forcing and driving the instrument, over use of reaming action, and over reliance on chelating agents.
Reason: Concepts concerning the role and purpose of this canal preparation, however, have differed remarkably at different times in the development of endodontics and in the hands of different practitioners. Thus in this review we will discuss about mishaps related to curved canals and its management.
