1/26. 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.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/26. 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.- - - - - - - - - - ranking = 0.09925251055711keywords = jaw (Clic here for more details about this article) |
3/26. 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.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
4/26. 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.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
5/26. 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.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
6/26. 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.- - - - - - - - - - ranking = 0.19850502111422keywords = jaw (Clic here for more details about this article) |
7/26. 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.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
8/26. 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.- - - - - - - - - - ranking = 4keywords = mandible (Clic here for more details about this article) |
9/26. 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.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
10/26. Clinical observations of odontomas in Japanese children: 39 cases including one recurrent case.Retrospective investigations of odontomas in Japanese children and one recurrent case were carried out. Thirty-nine cases of odontoma in 38 children were treated in the Paediatric dentistry Clinic of Niigata University Dental Hospital between September 1979 and December 2002. The patients consisted of 23 males and 15 females and their ages ranged from 1 year 2 months to 14 years old. The chief complaints were delayed tooth eruption in 19 cases (five: primary teeth, 14: permanent teeth), retention of primary teeth in 11, incidentally found on the radiographic examination in eight cases, and swelling of the jaw in one case. Thirty-four cases (87%) were associated with tooth eruption disturbances. The most frequently affected region was the maxillary anterior region. Treatment consisted of surgical removal of odontomas in all cases, after which if the impacted teeth did not erupt, exposure of the crown and/or orthodontic traction was performed. Pathological diagnoses were compound odontoma in 30 cases, complex odontoma (n = 7), and compound and complex odontoma (n = 2). A retrospective study of the radiographs revealed the developing process of odontomas in four cases and odontoma disturbed tooth eruption since the early uncalcified developing stage. A recurrent case was a boy aged 6 years 5 months in whom the first surgical removal of odontoma was performed at the age of 1 year 8 months. recurrence of an odontoma is very rare, but in very young children odontomas are in the early developing stages, containing uncalcified portions, so it is important to perform periodical observations until the succedaneous teeth erupt.- - - - - - - - - - ranking = 0.09925251055711keywords = jaw (Clic here for more details about this article) |
