Ossifying fibroma is classified as, and behaves like, a benign bone neoplasm. It is often considered to be a type of fibroosseous lesion. This bone tumour consists of highly cellular, fibrous tissue that contains varying amounts of calcified tissue resembling bone, cementum or both.1
Owing to the presence of both bone and cementum-like tissue in ossifying fibromas, these lesions are described using the terms “ossifying fibroma”, “cementoossifying fibroma” and “cementifying fibroma”.2 Nonetheless, the consensus is that these three terms describe the same underlying type of lesion.3,4
In most cases, ossifying fibroma is slow-growing, but it is occasionally aggressive, particularly its juvenile subtypes.
Additionally, its growth is usually concentric, and it is well demarcated from the adjacent bone. Some lesions may grow to become massive, causing considerable aesthetic and functional deformities. Clinically, ossifying fibroma is usually asymptomatic and is often found accidentally in routine dental examinations.
