Cemento-ossifying fibromas in the jaws of Hong Kong Chinese
Objective:
To determine the clinical and radiological features of cemento-ossifying fibroma (COF) in a Chinese population.
Methods:
Twenty cases of COF found in Chinese patients for whom the clinical notes, radiographs and histopathology reports were available, were reviewed to determine their clinical and radiological features. Overall size was measured digitally from the radiographs.
Results:
All COFs occurred in females and most frequently in the third and fourth decades. Seventeen COFs were in the mandible and three in the maxilla. Eighteen COFs had well-defined margins and were round or avoid in shape. Four were radiolucent and 15 mixed density. COFs tended to be smaller in women in their early to middle-40s and larger in older women.
Conclusions:
The clinical and radiological features of this Chinese series were broadly consistent with those of non-Chinese populations reported previously. The principal difference was that all 20 patients were female.
