An incisive canal cyst was misdiagnosed as an endodontic lesion. The patient's chief complaint was pain on mastication with increasing intensity for the last 2 days. The single original periapical radiograph revealed a well-circumscribed radiolucency related to the apex of the maxillary right central incisor. The patient was referred with a request for endodontic therapy. A subsequent angled radiograph revealed an interroot location of the lesion, and pulp testing showed a normal response. The patient was then referred for surgical treatment. Following removal of the lesion, the histopathologic examination confirmed the diagnosis of an incisive canal cyst. One-year follow-up showed complete healing and maintained tooth vitality, and the patient was asymptomatic.
