Resumo (EN)

Objective – Radiographic examination is the most affordable and widely used complementary examination in dentistry. Recently, techniques for digital panoramic radiography have been developed. Methods – A total of 1937 panoramic radiographies were evaluated in this study, the female group has accounted for the most of the sample: 1090 (56.3%) in comparison to 847 (43.7%) men. The patients were not identified, and data have only included gender, age, main injuries, anomalies and alterations at maxillofacial region or adjacent structures. Unusual injuries or doubtful diagnosis were excluded. Results – The most common injuries and alterations that were found in this study were teeth absence / anodontia, extrusion / inclination / migration / transposition / rotation, image suggestive of carious lesions and periapical lesions. The injuries and anomalies less common were condyle alteration, hypercementosis, mandible fracture, odontoma, dentigerous cyst, odontogenic keratocyst, periapical cement osseous dysplasia, foreign body, cleft palate and surgical fixation. Conclusions – Digital panoramic radiography is of the great value for lesions and anomalies diagnosis, as a complement of clinical practice. This study reports as the most common alterations teeth absence / anodontia, teeth extrusion / inclination / migration/ transposition/rotation, image suggestive of carious lesions and periapical lesions, which were predominant in the female group.
