[Supernumerary teeth in the maxilla and mandible-an interdisciplinary challenge. Part 2: diagnostic pathways and...

Proper localization of supernumerary teeth is very important for the diagnosis, treatment planning, and prior to any surgical intervention. Traditionally, supernumerary teeth were diagnosed and located using two-dimensional (2D) radiographic methods such as panoramic views, cephalometric imaging, and also intraoral (also often occlusal) radiographs. With the introduction of cone beam computed tomography (CBCT) in dental medicine, this three-dimensional (3D) imaging technique is now more and more used for the exact localisation of supernumerary teeth and the diagnosis of root resorption of adjacent teeth. Treatment planning depends on various factors such as the time of diagnosis, the age of the patient, the position of the supernumerary tooth and possible complications. In the present second part of this review article on supernumerary teeth in the maxilla and mandible, the diagnostic workflow and current treatment concepts will be presented and critically discussed.
