Condensing Osteitis
A focal area of increased bone density (radiopacity) at or near a root apex, typically in response to chronic low-grade pulpal inflammation.
Full Definition
Condensing osteitis, also called focal sclerosing osteomyelitis, manifests radiographically as a diffuse radiopaque mass at the apex of a tooth with a long history of pulpal irritation or necrosis. Unlike hypercementosis, the opacity is within the surrounding bone rather than on the root surface, and the periodontal ligament space may be obliterated or widened. It is most common in the mandibular molar and premolar regions and is generally asymptomatic. Editors working on radiology reports must ensure this term is not confused with 'periapical cemental dysplasia' or 'osteosclerosis,' which have different etiologies and radiographic appearances. The condition often resolves or diminishes after appropriate endodontic treatment.
Usage
Usage note: Both 'condensing osteitis' and 'focal sclerosing osteomyelitis' are acceptable; verify which the target journal prefers and apply consistently throughout the document.
In Context
- "A diffuse radiopaque lesion at the apex of the mandibular first molar was consistent with condensing osteitis secondary to chronic pulpitis." — Endodontic case report
- "The editor queried whether 'condensing osteitis' or 'focal sclerosing osteomyelitis' was the preferred term per the journal's house style." — Manuscript review correspondence
