Histologically, odontogenic fibromas can be divided into two types: epithelium-poor (simple type) and epithelium-rich (complex, or WHO type).
Histological examination revealed absence of any atypia or increased mitotic activity excluded malignancy, while the absence of osteoid formation and the prominent collagenization, helped distinguish the lesion from non-ossifying fibroma or odontogenic fibroma.
In 1980, Gardner described odontogenic fibroma and classified it into three different related lesions namely (1) the hyperplastic dental follicle, (2) a fibrous neoplasm with varying collagenous fibrous connective containing nests of odontogenic epithelium (CODF simple type) and (3) a more complicated lesion with features of dysplastic dentin or cementum like tissue with varying amounts of odontogenic epithelium (WHO type) which was later designated as CODF WHO type.
The above histological features along with clinical and radiographic findings were suggestive of simple type of central odontogenic fibroma.
