title: Dens in dente: an unusual sequela. Abbreviated case report.
abstract: Dens in dente is the result of an invagination of the enamel organ into the developing dental papilla. The full pathologic potential of this lesion is often not fully appreciated. A case is reported in which a cyst resulting from a dens in dente obliterated the maxillary sinus and necessitated root canal therapy and apicoectomies in four adjacent teeth.
