  • Ameloblastic fibro-odontoma is a rare benign mixed odontogenic tumor with histologic characteristics of ameloblastic fibroma and complex odontoma. As with ameloblastic fibroma, it may be asymptomatic or found because of painless swelling and delayed eruption of associated tooth. This report presents a case of ameloblastic fibro-odontoma in the posterior mandible of a 14-year-old girl and analyses its clinical features and radiographic features on plain X-ray film and CT images.

  • Ameloblastic fibro-odontoma(AFO) is a rare mixed odontogenic tumor. It is composed of connective tissue characteristic of an ameloblastic fibroma and calcified tissue as a complex or compound odontoma. AFO usually presents itself as an asymptomatic swelling of jaw or failure of tooth eruption. The lesion usually occurs in individual less than 30 years old. The differential diagnosis of this tumor includes odontoma, ameloblastoma, and ameloblastic fibroma. This report describes an ameloblastic fibro-odontoma occurring in maxilla of sixteen-year-old female. The lesion was treated by surgical enucleation and curettage without extraction of the involved canine(#23). This patient has shown no sign of recurrence during postoperative 34 months. So we report our case with review of literatures

  • Ameloblastic fibro-odontoma is a rare benign odontogenic tumor that mainly occurs at mandibular molar area. Radiography usually shows a well-defined radiolucent area containing various amounts of radiopaque material of irregular size and form. In histiologic aspect, Ameloblastic fibro-odontoma composed of connective tissue characteristic of an ameloblastic fibroma and calcined tissue identifying the tumor as a complex odontoma. Thirteen years two months aged boy of this case visited with chief complaint of delayed eruption of mandibular left canine. After enucleation of lesion, biopsy was done and diagnosed by ameloblastic fibro-odontoma. In continous follow-up check, canine erupted normally after operation.

  • Ameloblastic fibro-odontoma is an extremely rare odontogenic tumor composed of proliferating ectodermal and mesenchymal components of odontogenic tissue, containing hard tooth structure. It occurs predominantly in children and young adults. The mandibular molar-ramus area is the most frequently observed location, presenting radiographically as a well-circumscribed and radiolucent-radiopaque tumor. A case involving a 24-year-old woman presenting with a large ameloblastic fibro-odontoma of the posterior mandible is reported. This case is of radiologic interest because two distinct calcification patterns were observed.

  • Ameloblastic fibro-odontoma (AFO) is a rare odontogenic tumor, which occurs in young children before the age of 20 years. Radiologically, it is a well-defined radiolucent lesion containing radiopaque masses. Histopathologically, AFO is composed of odontogenic epithelium in a primitive-appearing connective tissue and hard tissue consisting of enamel and dentin. It is commonly found in the mandibular posterior region. AFO may be asymptomatic and is often associated with delayed tooth eruption. As it shows similar characteristics clinically and radiologically to odontoma, differential diagnosis through histopathological examination is important. Treatment of AFO is conservative enucleation, and teeth enclosed or associated with the lesion may require extraction. In this report, 2 young patients who visited our clinic with a chief complaint of delayed eruption were diagnosed as AFO with radiological and histopathological examination. After the surgery, the healing status was found to be favorable, and no evidence of recurrence was observed.

  • Thirteen-year-old girl complaining of the swelling and pain on the left midface visited our dental hospital. On the radiographic examination, well-defined radiolucent lesion with hyperostotic border was found in the left maxilla accompanying with the external root resorption of the involved teeth and the displaced second molar. CT showed calcified bodies, thinning of hard palate, inferior orbital wall and lateral wall of nasal fossa, and thinning and perforation of the buccal plate of the maxilla. Enucleation and curettage of the lesion and nasoantrostomy was carried out and histopathologic examination mainly showed a solid tumor tissue composed of odontogenic epithelium and pulp tissues admixed with dentin and enamel formation. And some part of reduced follicular epithelium of tooth germ showed a change mimicking calcifying odontogenic cyst. Taken together, we concluded the lesion is an ameloblastic fibro-odontoma with a change of calcifying odontogenic cyst.

  • Ameloblastic fibrodentinoma (AFD) is a rare benign odontogenic tumor that resembles an ameloblastic fibroma with dysplastic dentin. This report presents a rare case of mandibular AFD with imaging features in a young patient. Panoramic radiography and computed tomography revealed a well-defined lesion with internal septa and calcified foci, causing inferior displacement of the adjacent molars as well as buccolingual cortical thinning and expansion of the posterior mandible. The lesion was surgically removed via mass excision, and the involved tooth was extracted under general anesthesia. During the 5-year follow-up period, no evidence of recurrence was observed. Radiologic features of AFD typically reveal a moderately to well-defined mixed lesion with varying degrees of radiopacity, reflecting the extent of dentin formation. Radiologists should consider AFD in the differential diagnosis when encountering a multilocular lesion with little dense radiopacity, particularly if it is associated with delayed eruption, impaction, or absence of involved teeth, on radiographic images of young patients.

  • Adenomatoid odontogenic tumor (AOT) is a rare benign odontogenic jaw lesion. It usually occurs in the anterior maxilla and is mostly related to impacted canines in teenagers. A 3-year-old girl was referred from a local dental clinic due to delayed eruption of the right primary mandibular 2nd molar. There was no history of pain or swelling. Radiography revealed a large radiolucency lesion with radiopacities around the unerupted right primary mandibular 2nd molar. Surgical enucleation with extraction of the right primary mandibular 2nd molar and surgical biopsy were performed. Based on the clinical and radiological findings, this lesion was defined as an ameloblastic fibro-odontoma which often develops in the mandible of adolescents. However, this lesion was diagnosed as AOT from the results of the histological examination. This report aimed to present a rare case of AOT in the posterior mandibular area in a very young patient.
