A 15-year-old Caucasian girl presented for a routine dental evaluation, without a specific complaint, history of trauma or surgical procedures. An intraoral examination showed two holes at the side of the incisive papilla. The patient was unaware of their existence and there were no associated symptoms. Two gutta‑percha cones were introduced into the holes, verifying that they were approximately 2-cm deep and a periapical radiograph was performed. The diagnosis was bilateral total patent nasopalatine duct. The patient was informed about the meaning and implications of the anatomical changes found. We reported a new case of patent nasopalatine duct and this review also presents a review of related literature from 1881 to 2011.
