This study evaluated the consistency of digital panoramic results compared to digital periapical in evaluation of bone loss in anterior and posterior mandible and maxilla. For this purpose, 10 patients with digital panoramic images and parallel and digital full mouth periapical referred to the private department of radiology were recruited for the study. Images of the patients were used for the study if they consented. The patients (aged 17±38) had moderate and severe periodontitis in teeth 2, 3, 4, 5, 6 and 7. The distance between CEJ and bone height observed on the mesial and distal lateral incisors, canines, first and second premolars, first and second molars in periapical and panoramic images was measured by a measurement tool available in the software. Bone loss in the cement and enamel junction to alveolar bone crest in the mesial and distal lateral incisors, canines, first and second premolars, first and second molars was measured and recorded in the questionnaire by considering magnification. Measurements were done by a radiologist and two dental students and repeated in 2 weeks. There was no significant difference in two images in the teeth 2, 3, 4, 5, 6 and 7 on the right and left. Therefore, PA can be replaced by panoramic imaging in these teeth
