Condensing Osteitis
Pronunciation: kon-DEN-sing os-tee-EYE-tis
A diffuse radiopaque lesion of the jaw representing a localised bony reaction to low-grade periapical inflammation, characterised by increased bone density.
Full Definition
Condensing osteitis is a periapical bony reaction in which low-grade chronic inflammation stimulates the formation of dense, sclerotic bone rather than the radiolucency seen in most periapical pathologies. It appears radiographically as a diffuse periapical radiopacity, typically associated with a tooth with an infected or necrotic pulp. The lesion often resolves or diminishes following successful root canal treatment. Editors reviewing radiographic reports must not transpose this term with 'periapical periodontitis,' which presents as a radiolucency, nor with the physiological variant 'bone island' (idiopathic osteosclerosis). Accurate description is essential in insurance and medico-legal documents.
Usage
Usage note: Distinguish from radiolucent periapical lesions; this is a radiopaque finding — a critical distinction in radiographic reporting.
