Physiological root end development and closure takes up to 3 years following tooth eruption. Any traumatic injury during this period will hamper the root end development. Large periapical lesions occur as sequelae of pulpal disease and often present without any acute pain and are usually diagnosed on routine radiographs. Endodontic therapy must be aimed at the elimination of bacteria from the root canal system. This creates a favorable environment for the root end formation or induces an apical barrier in a tooth that has lost the regenerative potential. Availability of multitudinal materials which when used perspicaciously provide excellent results and annihilate the need for surgical intervention. Circumstantiated here is a case with a large periapical lesion in relation to the maxillary left central and lateral incisors, which resolved on treatment using the traditional gold standard material, Calcium hydroxide.
