Endodontic therapy aims to maintain the integrity of the natural dentition, to achieve proper form, function and esthetics. Root perforation is one of the most common mishaps during endodontic tooth preparation. A perforation is any communication between the root canal space and the periradicular tissues which may be iatrogenic or pathological in nature.1 Perforations that are present in the pulp chamber floors and cervical third of the root have a poor
