1/30. odontoma-producing intraosseous calcifying odontogenic cyst: case report.

    The present report describes a case of odontoma-producing intraosseous calcifying odontogenic cyst in a 36-year-old Black male in the right mandibular bicuspid region. The lesion involved an unerupted permanent canine, which was displaced to the mandible base and a calcified mass that was later recognized as an odontoma. The lesion was surgically removed.

2/30. Delayed tooth eruption associated with an ameloblastic fibro-odontoma.

    Delayed eruption of a single primary tooth is an uncommon event. Excluding a previous traumatic insult, the presence of a pericoronal odontogenic cyst or neoplasm is the primary cause for this abnormality. This case report describes the clinical and radiographic features of an ameloblastic fibro-odontoma in a young child, who presented with delayed eruption of the primary mandibular canine and prominent buccal expansion. A differential diagnosis for mixed, radiolucent and radiopaque lesions of the jaws will be discussed.

3/30. A case of an ameloblastic fibro-odontoma arising from a calcifying odontogenic cyst.

    This case report describes an ameloblastic fibro-odontoma arising from a calcifying odontogenic cyst (COC) in the mandible of a twenty-three-year old male. The patient was referred to the Department of Oral Surgery, tokyo Dental College, on March 30th, 2000, complaining of a painful swelling, which had appeared three weeks earlier on his left mandibular molar region. In a pathological view, the lesion was a round cyst the size of a chicken-egg, dark red in color, and surrounded by a thick membrane. The cyst had an epithelium of varying thickness which included many ghost cells and an enamel-like structure on the inside, and a thick wall of connective tissue with an ameloblastic fibro-odontoma on the outside. enamel organ-like epithelial islands were structured radially in the form of strands with immature dentin. Cytokeratin 19 was strongly immunoreactive in the epithelium of the lesion; osteopontin and osteocalcin reacted in the mesenchymal cells and weakly in the epithelial element of this tumor.

4/30. Ameloblastic fibro-odontoma.

    Ameloblastic fibro-odontoma is a benign, mixed odontogenic tumor most commonly encountered in the mandible of children or teenagers. Treatment of AFO is conservative and requires a long-term follow-up. Although some authors believe that ameloblastic fibroma, ameloblastic fibro-odontoma, and odontomas are extensions of the same disease process, they should be regarded as separate disease entities.

5/30. Ameloblastic fibro-odontoma: a case report.

    Ameloblastic fibro-odontoma is a benign epithelial odontogenic tumour with odontogenic mesenchyme exhibiting the histologic characteristics of ameloblastic fibroma and complex odontoma. It is usually associated with developing teeth and occurs predominantly in children and adolescents. In many cases, such lesions are found on radiographic evaluation of patients in whom eruption of teeth is delayed. Ameloblastic fibro-odontoma is generally asymptomatic but may cause swelling and discomfort. This report describes an ameloblastic fibro-odontoma in the posterior mandible of a 26-year-old woman and discusses the histogenesis and clinical features of the lesion.

6/30. Severe anterior open bite malocclusion with multiple odontoma treated by C-lingual retractor and horseshoe mechanics.

    A fixed lever arm appliance called C-lingual retractor was placed on the lingual aspects of the maxillary anterior teeth in a 16-year-old male patient with a Class II anterior open bite malocclusion. The treatment plan consisted of extracting both upper first premolars and retracting the upper six anterior teeth. A multiple odontoma between the lower left lateral incisor and canine was surgically removed before orthodontic treatment, and a horseshoe appliance was used in the lower dentition for intermaxillary anchorage during the bone-healing period. The transpalatal arches soldered to the upper first and second molar bands were used as an intra-arch anchor unit for upper-space closure. Class II elastics were used buccally between the upper six anterior teeth and the lower horseshoe appliance. We took 13 months to treat the open bite malocclusion. There was a decrease in lip fullness as the upper anterior teeth were retracted, which contributed to a decrease in facial convexity. The treatment result was maintained six months after debonding. Details of the new appliance, clinical procedures, and treatment changes are presented.

7/30. Aspiration cytology of ameloblastic fibroma: a diagnostic challenge.

    Ameloblastic fibroma of the jaw is a rare, benign mixed odontogenic tumor, having little tendency for local invasion and a low recurrence rate. Cytologic distinction from ameloblastoma, ameloblastic fibrosarcoma, and intraosseous adenoid cystic carcinoma is necessary, in view of the different biologic behavior. A painful, slow-growing swelling of the jaw in a 5-yr-old child clinicoradiologically considered as a benign cystic lesion was aspirated. Sheets of small monomorphic epithelial cells with peripheral palisading by columnar cells were seen on cytology smears. The striking feature was central hyaline globules in some tubules. A cytologic possibility of adenomatoid odontogenic tumor was suggested. Histopathology, however, confirmed it to be an ameloblastic fibroma.

8/30. Sialolithiasis or complex odontoma?

    We present a case of a 53-year old woman admitted for treatment in the clinic after detection of radiopacity in the left half of the mandible. The patient was operated on with a tentative diagnosis of complex odontoma. No pathological lesion was found intraoperatively after trepanation of the mandibular bone. Additional clinical examination and contrast media sialography of the left submandibular salivary gland in PA and lateral oblique view were instrumental in making the correct diagnosis and administering the proper treatment. This case demonstrates that difficulties may arise in differentiating between a sialolith and a complex odontoma.

9/30. Rare compound odontoma of the mandible in a 7-year-old child: case report.

    BACKGROUND: A compound odontoma is a mixed tumor of odontogenic origin, in which both ectodermal and mesenchymal cells exhibit complete differentiation, resulting in the formation of tooth structures. It occurs with equal frequency in both sexes, and is often initially asymptomatic. CASE REPORT: A 7-year-old boy was recently examined in our Department for management of a compound odontoma. Surgical treatment was invasive because of the size of the lesion, but it was possible to use interceptive orthodontic treatment to restore the dental arch.

10/30. Erupted complex odontoma: a case report and literature review.

    A case involving a 17-year-old girl with a large erupted odontoma associated with a deeply impacted mandibular molar is reported. The molar, which previously had been displaced to the border of the mandible, erupted successfully three years after surgical removal of the odontoma. A review of the literature presents guidelines for treating similar cases.
