Abstract: A periapical cyst (Radicular cyst) is most common odontogenic cyst of oral cavity which arises from epithelial remnants which form by an inflammatory process originating from pulpal necrosis of a non-vital tooth. This cyst associated with non-vital tooth and generally visible on radiographs. Radiographic interpretation of the lesion is a round or oval, well circumscribed radiolucency involving the apex of the tooth. A 14-year-old female patient reported to department of conservative dentistry and endodontics with chief complain of discoloured tooth since one year and mobility in maxillary left anterior teeth (#22) since 3 months. Clinical and radiological findings were suggestive of periapical radicular cyst. Non-surgical endodontic therapy was performed using 5% sodium hypochlorite, 2% chlorhexidine and normal saline and Calcium hydroxide intra canal medicament. A 3 months follow-up radiographic examination revealed progressive involution of periapical radiolucency without any clinical symptoms. Periapical cysts respond favourably to non-surgical endodontic treatment.
