Frequency and pattern of idiopathic osteosclerosis and condensing osteitis lesions in panoramic radiography of Iranian patients

Abstract

Background: The purpose of this study was to investigate of radiographic pattern and relative

frequency of idiopathic osteosclerosis (IO) and condensing osteitis (CO) in panoramic radiographs.

Materials and Methods: Totally 411 panoramic radiographies were randomly selected from

patients referred to Radiology Department of Faculty of Dentistry, Tabriz University of Medical

Sciences. Descriptive characteristics of radiopacities, including shape, border, localization, and dental

relationship, were recorded. The Chi‑squared test was used.

Results: IO was detected in 31 (7.5%) patients and 22 (68.8%) lesions had exact border while

their shape was mostly irregular. About 17 (53.1%) lesions were apical, and 13 (40.6%) lesions had

no relation to the teeth. The most involved teeth were the second premolar (28.1%) and first

molar (25%). Moreover, CO was detected in 32 (7.8%) patients. 17 (53.1%) lesions had an ill‑defined

border, and their shape was mostly irregular (65.6%) with ill‑defined border. Around 18 (56.3%)

lesions were apical, and 11 (34.4) lesions were apical and interradicular. The most involved teeth

were the second premolar (59.4%) and the first molar (21.9%).

Conclusion: The results demonstrated that relative frequency of IO in the selected population

was 7.5% and for CO, it was 7.8%.
