When non-surgical root canal treatment fails to resolve periradicular lesions of endodontic origin or if retreatment is not feasible surgical intervention is recommended. Management of root end during endodontic surgery involves apical resection,retropreparation and retrofilling to seal the root canal. Numerous materials have been suggested and the newer ones like MTA, Castor Oil Polymer and calcium phosphate have shown promising results. This article is a review of literature on the suitability of various root end filling materials based on their leakage assessment, marginal adaptation, cytotoxicity and usage tests in experimental animals and humans.
