Abstract
SEBASTIAN SEBASTIAN, C.; HERNANDEZ, B. Izquierdo; GUTIERREZ ALONSO, C. and ASO VIZAN, A.. Dientes supernumerarios: claves esenciales para un adecuado informe radiológico. Rev. argent. radiol. [online]. 2016, vol.80, n.4, pp.258-267. ISSN 1852-9992.
Purpose: A significant increase has been observed in computed tomography (CT) requests for the pre-operative evaluation of supernumerary teeth (SN) in children. The aim of this work is to describe the SN teeth in a detailed and concise fashion, based on patients diagnosed in our institution. Materials and methods: A retrospective analysis of maxillofacial CT studies was performed during the years 2011 to 2015. Patient data was collected, including gender and age, request data, and CT findings. The SN were classified in accordance with the World Dental Federation (FDI) notation, describing LEOMA variables (location, emplacement, orientation, morphology, and angulation), and the presence of associated disorders (heterotopia, inclusión, ankylosis, or odontoma). Results: The study included 36 patients with a total of 49 SN teeth. The most frequent request was a pre-operative CT evaluation of SN teeth (21 cases). The SN teeth were found in the mesiodens location (30 SN), posterior position in relation to the closest tooth (25 SN), conical rudimentary morphology (26 SN), vertical orientation (19 SN), and anterior-posterior angulation. Conclusion: Providing an adequate description of SN teeth can help the radiologist to write a detailed and concise report and help the maxillofacial surgeon in the pre-operative planning.
