Patent nasopalatine ducts: a case report

This report describes a patient with a history of trauma to root-filled tooth 11. Openings on either side of the palatal incisive papilla were found to be unrelated to the adjacent teeth, and patent nasopalatine ducts were diagnosed. Reports of this condition are uncommon, possibly because it is rare, or difficult to detect, or both. Most of these ducts are asymptomatic, and are usually treated only at the patient's request.
