| Summary: | A male patient aged 28 years presented with a chief complaint of discolored left central incisor and missing tooth, due to road traffic accident 15 years ago with no associated symptoms. Clinical and radiographic examination revealed no pulp to response to vitality test, large periapical radiolucency, and root resorption of the middle third of the root. A definite diagnosis of pulpal necrosis with asymptomatic apical periodontitis and external resorption was made. Root canal treatment was done, and the extent of the lesion was analyzed and planned for surgical management. The periapical lesion was curetted, and the external resorption site was sealed with a matrix of Biodentine and platelet-rich fibrin. The case has shown successful healing after 3-year follow-up.
