Abstract
Calcific metamorphosis is also called pulp canal obliteration. Canals can be partially or fully obliterated. Most common reasons for calcified canals are trauma and aging. These calcific deposits can cause a considerable challenge to the dental practitioner in locating the canals, reaching the working length and also cleaning and shaping the canals. Attempt to negotiate the canals and perform biomechanical preparation without proper and thorough knowledge on management of calcified canals can lead to iatrogenic errors caused by the clinician such as perforation, fracture of instrument, transportation etc.Most important thing before attempting to negotiate such calcified canals is to have a thorough knowledge on the normal anatomical form and morphology of the root canal system of the particular tooth. Practicing under dental loupes or microscope can add to the clear vision and aid in locating and negotiating the canal. Different armamentarium is available for this purpose like basic small size k file, c pilot files, Endo guide burs, ultrasonic, chelating agents, endodontic surgery to advanced Guided Endodontics.
