Purpose: Idiopathic osteosclerosis is a common radiopaque lesion without clear cause that affects the mandible and maxilla. This study was conducted to assess the prevalence of idiopathic osteosclerosis in the jaws among Egyptian population.
Subjects and Methods: 1100 CBCT scans were used to assess the prevalence, gender and age distribution, location, and size of idiopathic osteosclerosis.
Results: Idiopathic osteosclerosis was found in 16.7% of the cases with equal distribution in males and females patients, especially, in the third decade. Mandibular lesions were found in 95.7% of them, 52.7% in molar region and 29.9 % in premolar region. The size ranged from
1.5 – 15.6 mm.
Conclusion: Idiopathic osteosclerosis is not uncommon radiographic finding in Egyptian population with predilection to premolar-molar mandibular region.
