title: Anomalous morphology of an ectopic tooth in the maxillary sinus on three-dimensional computed tomography images.
abstract: We describe a case of an incidentally-diagnosed ectopic tooth showing anomalous morphology in the maxillary antrum, using three-dimensional reconstruction of computed tomography images of the tooth obtained by multi-detector computed tomography.
