Introduction and objectives: Curved roots with curved canals is the result of a developmental anomaly in which there has been an abrupt change in the axial inclination between the crown and the root of a tooth, but the criteria in the literature for recognizing root dilaceration vary. Two possible causes of dilaceration are trauma and developmental disturbances, and it has also been proposed that it might be associated with some developmental syndromes. It can be seen in both the permanent and deciduous dentitions, and it is more commonly found in posterior teeth and in the maxilla. Periapical radiographs are the most appropriate way to diagnose the presence of root dilacerations. Diagnosis, endodontic access cavity preparation, root canal preparation and filling, and other related treatments might be complicated by the presence of a dilaceration Conclusion: A thorough knowledge about internal anatomy of the tooth, appropriate instrumentation techniques and customized treatment planning depending upon the degree of curvature will help manage curved canals, prevent complications and enhance the quality of the treatment Key Words: Dilaceration, Schneider, Ledges, Strip Perforation .
