Case Discussion

Idiopathic osteosclerosis is an area of increased bone. Usually appears to be elliptical, round,  or irregular and radiopaque in shape. No expansion

Also known as dense bone island, bone scar, focal periapical osteopetrosis, or enostosis

These lesions may be accepted as developmental intraosseous anatomic variations and should be classified separately from the cases resulting from an inflammatory origin or systemic disease. These asymptomatic lesions are discovered as incidental findings on radiographs taken for other reasons. 90% in the mandibular first molar area.

Differential diagnosis

  • condensing osteitis (focal chronic sclerosing osteomyelitis): tooth associated
  • osteoma
  • sialolith
  • multiple lesions: suspicious for osteomas / rule out Gardner syndrome
