title: Migration of gutta-percha point from a root canal into the ethmoid sinus.
abstract: There have been reports on the migration of teeth or implants into the maxillary sinus, but we know of no report on the migration of a gutta-percha point that had been used to fill a root canal into the ethmoid sinus. We report such a case which presumably migrated through the maxillary sinus.
