There are four types of fibroids:
- Ossifying fibroma
- Nonspecific fibrous tumor
- Non-osseous fibroma
- Elastic fibrous tumor
Fibrous tumors within the bone do not have distinct clinical or radiological signs. There is a great similarity between fibrous tumors of odontogenic origin and fibrous nonspecific tumors, and it is difficult to distinguish between them even histologically.
- The most important thing is to distinguish between fibroma and osteofibroma
Ossifyingfibroma – A benign tumor, but it is considered a reaction rather than a tumor, and it can be peripheral or central. - Peripheral ossifying fibroma – A relatively common gingival growth. Most researchers agree that it is a lesion of dental origin that can affect any age, but it occurs more frequently in children and adolescents, and often in the molar area.
Clinical features of the tumor:
It is found exclusively on the gums and is in the form of a mass with a neck covered by mucus similar to the color of the gums. Its surface is sometimes ulcerated. The surface of the tumor is covered by layered, often ulcerated, paved skin. The colors range from pink to red, and most of them are 2 cm in size or less.
Radiological manifestations:-
X-rays do not reveal most cases, except for those that include superficial bony formations.
Histological features:
The tumor mass is composed of fibrous connective tissue, in which fibrous cells are abundant. The blood vessels are not abundant, and various forms of calcification are observed, which may be in the form of crossed or multiple blocks of bone. In less common cases, the presence of calcareous material from the cellular cementum is observed.
Treatment and warning:
The lesion must be surgically removed, preferably using laser technology, along with trimming the bone and polishing the roots of adjacent teeth. The recurrence rate ranges from 16-20%.
Clinical condition:-
The patient, M.F., 37 years old, saw me. She has a tumorous mass in the posterior part of the right upper jaw, pushing towards the dome of the jaw, and she has been suffering from it for 5 years. The mass was removed with a laser, then the first and second molars were extracted, the bone was trimmed well, and the place of the extracted molars was sutured. The result of the histopathology was a healthy calcified fibrous tumor.
