The aim of this study was to compare the presence of dental development anomalies (DDA): number, size and shape, detected by panoramic radiographs (PRs) and Cone Beam Computed Tomography (CBCT). Images of 114 patients were analyzed on a consensus by three oral and maxilofacial radiologists in order to identify DDA in each exam modality. After the statistics it was concluded that CBCT allowed the detection of a greater number of DDA as compared with PRs.
