If there is dentin formation, the lesion should be diagnosed as AFD; if there is also enamel formation, it should be diagnosed as AFO. The pathological diagnosis was an ameloblastic fibro-odontoma.

The mass contained calcified material and an ameloblasticc deposit. In addition, AF and AFO have been defined as hamartomatous lesions and are believed to be stages of odontoma formation. The flap was repositioned in the same position and suturing was done with vicryl 3.

Aggressive atypical ameloblastic fibrodentinoma: Report of a case

Mixed odontogenic tumours dentknoma odontomas. There was grade II mobility with respect to 44 and 45, while the 46, 47 and 48 were absent.

Examination of the oral cavity revealed a bony hard swelling extending from the right first premolar to the angle area. The case presented here also showed an aggressive growth pattern and the histological study revealed few areas showing increased cellularity and cellular pleomorphism, raising a doubt toward the malignant transformation of the lesion. AFO is normally found in young patients, with no significant gender predilection.

Abstract Ameloblastic fibroma and related lesions constitute a group of lesions, which range in biologic behaviour from true neoplasms to hamartomas. The orthopantomogram revealed a well-defined radiolucency measuring about 4. Metastasis is not common and fatal cases have usually been associated with uncontrollable local infiltration following numerous recurrence.

The periapical radiograph revealed no periapical lesion, root resorption, or radiopaque abnormality Figure 1 c. A proper clinical, radiological and histological corelation should be established before considering a lesion as a benign or a malignant variant, and the treatment should be planned accordingly. Most studies suggest that conservative excision of the tumor with minimal but adequate margins is the treatment of choice [ 46 ]. Giraddi GB, Garg V.

Orthopantamograph revealed a well defined unilocular radiolucency extending from 72 to 85 Click here to view. There is a controversy in the literature regarding extraction or retaining the associated tooth bud in the case of AFO.

Ameloblastic fibro-odontoma

Jyothi Issac was the Pedodontist for the ameloblastuc. Because this lesion clinically resembles other nonneoplastic lesions and is very rare in gingiva, establishing a correct diagnosis is achieved only based on specific histological characteristics. Int J Pediatr Otorhinolaryngol Extra ; 1: Introduction The ameloblastic fibro-odontoma AFO is a rare benign odontogenic lesion defined as a tumour with the general features of ameloblastic fibroma but that also contains enamel and dentine.


Clinicians when dealing with radiopaque mass in posterior maxilla of children should keep the possibility of rare mixed odontogenic tumour in mind. This is usually in association with unerupted molar teeth in childhood.

Therefore, in place of planning a conservative treatment, a radical resection should be performed especially if the lesion is aggressive and presents with erosion and perforation of the cortical plate.

Usually, AFD radiographically presents as a well-defined radiolucency, with little dense opacity. The reported extraosseous tumors do not appear in the oral mucosa other than gingiva.

The malignant counterpart of these lesions namely aameloblastic fibrosarcoma, ameloblastic dentinosarcoma and ameloblastic odontosarcoma respectively are said to arise secondarily in their benign counterpart or de novo. The borders were not sclerotic.

A fibrillar pattern reminiscent of dentinal tubules was noted in the focal area as marked [ Figure 4 ]. Case report A year-old girl was referred to oral and maxillofacial surgery department with an incidental radiological finding of radiopaque mass in the posterior region of maxilla.

Both epithelial and fibrous elements may therefore represent those of odontogenic fibroma fibdo or without dentin formation. Khalam for review of literature. National Center for Biotechnology InformationU. Ameloblastic fibroma and related lesions:
