Central Ossifying Fibroma

Micrograph of a central ossifying fibroma.

Central Ossifying Fibroma is a rare benign tumor that originates from the mesenchymal tissue of the jawbones. It is characterized by the formation of fibrous tissue and the presence of calcified material, resembling bone. This article provides an overview of the central ossifying fibroma, including its etiology, clinical features, diagnosis, and treatment options.

Etiology

The exact cause of central ossifying fibroma is still unknown. However, it is believed to arise from the cells of the periodontal ligament or the dental follicle. Some studies suggest that trauma or local irritation may play a role in the development of this tumor. Additionally, hormonal factors and genetic predisposition have also been proposed as potential contributing factors.

Clinical Features

Central ossifying fibroma commonly affects individuals in their second to fourth decades of life, with a slight female predilection. It most commonly occurs in the mandible, particularly in the premolar and molar regions. However, it can also involve the maxilla. Patients may present with painless swelling, facial asymmetry, or displacement of adjacent teeth. In some cases, the tumor may cause expansion of the jawbone, leading to facial deformity.

Diagnosis

The diagnosis of central ossifying fibroma is based on clinical, radiographic, and histopathological findings. Radiographically, it appears as a well-defined radiolucent lesion with variable amounts of calcifications. Computed tomography (CT) and magnetic resonance imaging (MRI) can provide additional information about the extent and involvement of adjacent structures. Histopathologically, the tumor is characterized by the presence of fibrous connective tissue with varying degrees of calcifications, resembling bone.

Treatment

The treatment of central ossifying fibroma involves surgical excision of the tumor. The extent of surgery depends on the size and location of the lesion. In some cases, a conservative approach may be adopted, with regular follow-up to monitor any recurrence. Reconstruction of the affected jawbone may be necessary in cases where significant bone loss has occurred. Long-term follow-up is essential to detect any recurrence or malignant transformation.
