title: Nasal fistula associated with dental infection: a report of a case.
abstract: Most clinicians have come across a patient with difficult symptoms to diagnose. Often confusion occurs between odontogenic and nonodontogenic causes of sinus discomfort. On many occasions, sinus pain is due to purely dental causes, whereas in other situations dental pain is reported when the sinuses are infected. Due to the intimate association between the roots of the maxillary teeth and the floor of the nasal cavity and maxillary sinuses, diagnosis may be difficult. The following is a case report of a nasal fistula that developed from an abscessed maxillary central incisor.
