A propos d'un cas clinique de prise en charge d'une dent double: apport de l'approche numérique

Abstract : Double tooth is an anatomic variation referring either to a tooth stemmed from a fusion or a gemination. The root’s number will influence surgical treatment possibilities, conditioning a possible root separation, and the root canal anatomy will determine the necessity and difficulty of an endodontic treatment preceding any other tooth rehabilitation. This case report describes a fused permanent central incisor leading to an aesthetic and functional complaint. The Cone Beam Computed Tomography (CBCT) required for another symptomatic tooth was used to create a 3D model of the double tooth. This 3D planification allowed to establish the absence of an endodontic communication between the incisor’s two fused roots, which can be difficult to appreciate on the X-ray , as well as preparing the root separation surgery that was then realized. A few months later, the tooth became necrotic and another CBCT was prescribed. The endodontic treatment being necessary, a second 3D planification was conducted in order to analyze the anatomic modifications resulting from the root separation, to verify the absence of an endo-perio lesion and in fine compare two printed 3D models: one pre-op and one post-op. This approach is useful in the understanding of a complicated anatomy through three dimensional modeling and facilitates
