Abstract
Clinicians are regularly confronted with different choices after failure of root canal treatment. In present scenario patient prefer to retain their original teeth thats why non-surgical retreatment should be the treatment of choice. The new generation of endodontic instruments, magnification, materials and technology with the basic principles of endodontic retreatment have helped in retention of the patients natural tooth structure to form and function decreasing the need for extensively expensive prosthetic replacement in the area of implant dentistry. Surgical approach can be adopted in obstructed, calcified or non-negotiable canals.
Highlights
Evolutionary introduction and widespread adoption of the operating microscope has enhanced vision and magnification allowing success for untreated root canal systems, poorly obturated root canals, coronal microleakage, undetected cracked tooth, an obstruction, a ledge, a perforation or an instrument fracture indicating non healing associated with the previous treatment. [1] Persistent intraradicular infection occurs most frequently when the original treatment falls short of acceptable technical standards, missed canals, inadequate shaping, cleaning and obturation of the root canal system [2]
2 DISCUSSION: Retreatment ensures that the entire root canal system and any communicating channels are thoroughly cleaned and a good quality root filling is placed under optimal asepsis in every canal
Endodontic failures can be attributable to inadequacies in cleaning, shaping, obturation, iatrogenic events or reinfection of the root canal system when the coronal seal is lost after completion of root canal treatment

To gain entry into the root canal system coronal access is required. The clinician may be familiar with various techniques to remove coronal restoration and safely remove a variety of CMRO 03 (07), 494−502.
