Identification of the Endodontic System in Carnassial and Canine Teeth in the Dog

Abstract

A single radiograph of the endodontic system of a canine or carnassial tooth provides a two-dimensional image. Serial sectioning of these same teeth achieved a three-dimensional image, which may assist our understanding and therapies of these teeth. From the three dimensional images it was noted that the pulp chambers and root canals closely approximated the external topography of the teeth, with the exception of the palatal root of the maxillary fourth premolar tooth, and with this similarity becoming less obvious as the tooth matured. Developmental fissures were present in many teeth. Variations in the morphology of the endodontic system were noted in the distal root of the first mandibular molar tooth and the palatal root of the maxillary fourth premolar tooth. Accurate radiographs, with attention to these variations, are important determinants for successful endodontic therapy.
