Patient referred by a colleague for diagnosis and management due to a radiolucent radiographic image of the right anterior region. Asymptomatic patient. Clinical examination revealed malformation in the mesial region of tooth 12 and positive periodontal probing of 5 mm in the same region. Vitality testing revealed normal responses for teeth 11, 12 and 13. Radiographic examination revealed a periapical radiolucent image in the region of tooth 22 and an image of a bone defect in the mesial periradicular region of tooth 12. The case highlights the need for a more detailed examination to avoid misdiagnosis in cases of periapical lesions. The patient was indicated for tomographic examination and a better observation of the area will allow a more accurate establishment of a diagnostic hypothesis, and only then a treatment can be established.

Case conducted by the students Carlos and Vinícius from the Specialization in Endodontics of HPG Brasília.
