Dataset of dental radiographs for the study of periapical lesions

Dataset contains 450 conventional diagnostic periapical radiographs of anterior teeth. These were acquired from the Endodontics Department of the Facultad de Odontología, Universidad Nacional de Asunción. The radiographs were digitized using three cameras, a professional Canon T6 camera with a 100mm macro lens, a smartphone with iOS operating system (iPhone X) and a smartphone with Android operating system (Xiaomi Redmi Note 8). Then, five dental specialists performed the classification of the images by labeling with and without lesion.
