Bottom Line: Microscopic examination showed islands, chords and strands of odontogenic epithelium in a primitive ectomesenchyme resembling dental papilla.The odontogenic epithelium exhibited peripheral ameloblast-like and central stellate reticulum-like cells.The presence of dentinoid material was seen adjacent to the odontogenic epithelium in some foci.

ABSTRACT
Ameloblastic fibrodentinoma is a rare benign mixed odontogenic neoplasm usually occurring in the first two decades of life. It is more common in males and the most common site of occurrence is in the mandibular premolar molar area. This report presents a case of ameloblastic fibrodentinoma in a 12-year-old boy in the maxillary anterior region, a less common site for the occurrence of ameloblastic fibrodentinoma. A 12-year-old boy presented with a midline diastema in 11 and 21 region and a swelling in the palatal aspect of 11 and 12. Intraoral periapical radiograph showed the presence of rarefaction of bone on the mesial aspect of the cervical and middle third of the root of 11. Excision biopsy was done. The specimen was processed and stained with hematoxylin and eosin. Microscopic examination showed islands, chords and strands of odontogenic epithelium in a primitive ectomesenchyme resembling dental papilla. The odontogenic epithelium exhibited peripheral ameloblast-like and central stellate reticulum-like cells. The presence of dentinoid material was seen adjacent to the odontogenic epithelium in some foci. The lesion was diagnosed as ameloblastic fibrodentinoma.

Mentions: A 12-year-old boy came to the Department of Oral Medicine and Radiology with a chief complaint of a growth of the gingiva on the palatal aspect of 11. The growth appeared along with the eruption of the upper front teeth. At the time of eruption, there was midline diastema in 11 and 21 region with a nodule of tissue in between, which the patient pinched out 1 year back (Figures 1, 2(a), and 2(b)). He gave a history of trauma to the anterior teeth 8 months back. On intraoral examination, full complement of permanent teeth except the third molars was present. A midline diastema of 0.5 cm was present between 11 and 21 with slight labial displacement and extrusion of 11. There was a well-defined swelling of 2 × 2 cm size on the palatal aspect of 11, 12 involving the marginal and attached gingiva that extended into the midline area. It was pale pink in color with an intact epithelium and a nodular surface. It was nontender, soft in consistency, nonfluctuant, compressible, and nonindurated. Radiographic examination showed spacing between 11 and 21 with the alveolar crest at the cementoenamel junction, rarefaction of bone on the mesial aspect of the cervical and middle third of the root of 11, and a diffuse periapical radiolucency in relation to 21. There was no gross alteration in the trabecular pattern (Figure 3).
