Periapical and panoramic radiography with a ellipsopantomograph device, are compared in the evaluation of endodontic treatment. With this objective, radiographies carried out under both techniques with the same patient having at least one tooth endodontically treated, were analysed by three observers, taking into consideration the apical conditions (periapical lesions), the root canal filling (material type, filling and apical level), tooth restoration and filling of the pulpar camera. The results demonstrated that periapical radiography is a better way to define the appearance of difuse periapical bone rarefaction, root canal filling with gutta-percha, insatisfactory endodontic treatment, an inadequate juxtaposition of the restoration material to the anterior region, and the presence of metallic casted restorations in the posterior region. Other result evaluations were not significant. The diagnostic agreement among the observers is higher in periapical radiography.
