2017-12-28 · In atypical cases involving the periapical region, three-dimensional radiographic assessment via cone-beam CT (CBCT) may be mandatory, especially in the early stages of disease, to facilitate differential diagnosis with other radiolucent periapical pathoses. uted to periapical periodontitis in a 39-year-old patient, who was admitted with persistent toothache, fever, and chest pain. Chest CT showed a feeding vessel sign and a target sign. A pan-oramic radiograph of the left maxillary bone showed alveolar bone loss in a horizontal pattern typi-cal of periodontitis and periapical periodontitis.

When a root-filled tooth causes swelling and/or pain it is usually a sign of infection. In combination with the presence of a periapical bone lesion visible in an intraoral radiograph the diagnosis of apical periodontitis is usually quite straightforward. Objectives. This paper aims to review the diagnostic application of cone beam computed tomography (CBCT) in the field of periodontology. Data. Original articles that reported on the use of CBCT for periodontal disease diagnosis were included.

If found in an advanced state or left untreat- ed, disease related to the tooth may spread to adjacent tissues, including Periapical radiolucencies are commonly observed findings on OPG and other dental/head and neck imaging modalities. Differential diagnosis They can represent a number of pathologies: periapical lucency related to apical periodontitis periapica Periapical granuloma (plural: granulomas or granulomata) refers to a localized mass-like region of chronic granulation tissue in relation to teeth formed in response to infection. It often results in relation to chronic apical periodontitis.
