Central Odontogenic Fibroma


Brenda L. Nelson, DDS, MS










This central odontogenic fibroma has a loose stroma with fine collagen fibrils and small odontogenic epithelial rests image. Odontogenic rests are not always seen.






Dense fibrous stroma with a vague whorling pattern and focal calcifications image are characteristic of the variant referred to as the WHO type. This subclassification is being phased out.
