Radicular cysts are common cystic lesions that affect the jaws. They are most commonly found at the apices of teeth with necrotic pulp, usually asymptomatic but can result in swelling in the affected area. A 52-year-old female patient presented with persistent labial swelling for 2 years after endodontic retreatment of maxillary right central incisor. Surgical enucleation of the cystic lesion together with regenerative technique using bone graft to manage the through and through (tunnel) bony defect was done. Both clinical and radiographic examination revealed a good healing at the 6-month follow-up. In conclusion, the use of bone graft during endodontic surgery to manage large periapical lesions with tunnel bony defect is an effective treatment strategy to accelerate bone healing.
