The tumor was removed under local anesthesia and the excised specimen measured Images hosted on other servers: Irregular trabeculae of lamellar bone are also evident. Cementifying fibroma is round in shape and causes nodular or dome shaped jaw finroma while fibrous dysplasia is rectangular and causes elongated fusiform expansion.
The orthopantomogram revealed the presence of well-defined radiolucency in 24, 25, 26, 27 regions figure 2 B. Histological analysis showed a cellular fibroblastic tissue characterized by bundles of collagen densely packed and proliferating fibroblasts.

A thin radiolucent line representing a fibrous capsule may separate it from surrounding bone. The margins of the lesion appeared to be well-defined.
Computed tomography CT scan showed expansion of the buccal and lingual cortical plates of the mandible [ Figure 3 ]. The maxillary cross-sectional occlusal radiograph demonstrated a round-shaped well-defined radiolucent lesion extending from 24 to 27 region.

Takakazu et al 8 conducted a clinical roentgenographic analysis of eight cases of cementifying fibroma and observed that out of eight, three demonstrated cystic radiographic appearance, four revealed fibroa radiographic appearance while foffy appearance was seen in only one patient.

Mandibular central cemento-ossifying fibromas usually shell out easily at surgery, but maxillary central cemento-ossifying fibromas are more difficult to remove completely than mandibular central cemento-ossifying fibromas. The patient mentioned that the mass had first appeared 3 months ago and became slightly larger since then.
Conservative surgery is therefore recommended even if the tumour is large with bowing and erosion of the inferior border of the mandible and radical treatment of the tumour such as an en bloc resection should only be considered if there are recurrences cementifjing to its aggressive nature. However, Eversole and his co-workers in a study of 64 cases of cemento-ossifying fibroma reported a recurrence rate of as high as 28 per cent following surgical curettage of these lesions.
