1/13. Adenomatoid odontogenic tumor arising in a dental cyst: report of unusual case.The case of an adenomatoid odontogenic tumor developing over a dentigerous cyst is reported. A 12-year-old boy was referred by his pediatric dentist to the service of Oral and Maxillofacial Surgery of the Asturias Central Hospital (spain) for evaluation of a radiolucent image compatible with a dentigerous cyst. Microscopic examination revealed the presence of an adenomatoid odontogenic tumor located over the linear epithelium of a dentigerous cyst. Based on the literature, the clinico-pathological, diagnostic, radiological and therapeutic characteristics of the case are commented in detail.- - - - - - - - - - ranking = 1keywords = dentigerous cyst, dentigerous (Clic here for more details about this article) |
2/13. Adenomatoid odontogenic tumour: a case study with radiographic differential diagnostic considerations.Adenomatoid odontogenic tumours (AOT) are benign, hamartomatous odontogenic lesions that not uncommonly mimic a dentigerous cyst radiographically. Such a case as found involving an unerupted left maxillary canine in a 19-year-old Chinese female is described. The differential diagnosis of some common odontogenic cysts and neoplasms occurring in Malaysians, that may present in a dentigerous relationship to an unerupted tooth is discussed. A brief review of the radiographic literature on AOT is also included.- - - - - - - - - - ranking = 0.44081473185671keywords = dentigerous cyst, dentigerous (Clic here for more details about this article) |
3/13. Repair of an intrabony defect from an adenomatoid odontogenic tumor.This case report describes the occurrence and treatment of an adenomatoid odontogenic tumor (AOT) presenting as a periodontal intrabony defect on a upper lateral incisor. Following incision and flap reflection, a solid, rubbery specimen was enucleated in one piece leaving a wide moat-like intrabony defect. A bioabsorbable membrane of glycolide and lactide copolymer was sutured over the defect to maximize regeneration and the flaps then sutured over the membrane. Microscopic analysis of the biopsied specimen revealed dental hard tissue interspersed in a field of odontogenic epithelium in a glandular configuration, consistent with a diagnosis of AOT. AOT is a rare odontogenic tumor usually associated with unerupted teeth or dentigerous cysts, not periodontal defects. Clinical evaluation 6 months postoperatively revealed restoration of clinical attachment and periodontal health.- - - - - - - - - - ranking = 0.33333333333333keywords = dentigerous cyst, dentigerous (Clic here for more details about this article) |
4/13. An adenomatoid odontogenic tumor with unusual clinical features.Adenomatoid odontogenic tumors are uncommon odontogenic lesions characterized by duct-like structures that form from the epithelial component of the lesion. Most of these masses develop in the second or third decade of life, and there is a strong female bias in occurrence. Typically, these lesions arise in the lateral incisor/canine region of the maxilla, where they produce a swelling. Only in very rare cases is the lesion found distal to the premolar area. Nearly all of these growths are associated with an embedded anterior maxillary tooth (usually a canine), and most resemble a 1-3 cm diameter dentigerous cyst. Radiopacity is reported in two-thirds of cases. This article describes the case of a 9-year-old Caucasian male who presented with a painless swelling in the left premolar-molar region of his maxilla. This case is of particular interest because the features (patient age, gender, lesion location, size, and radiographic findings) were not typical of adenomatoid odontogenic tumor.- - - - - - - - - - ranking = 0.33333333333333keywords = dentigerous cyst, dentigerous (Clic here for more details about this article) |
5/13. Adenomatoid odontogenic tumor mimicking a dentigerous cyst.Adenomatoid odontogenic tumor (AOT) is a slow-growing, asymptomatic and uncommon lesion that arises from odontogenic epithelium with inductive effects on connective tissue. The more common variant is the follicular type, which involves an unerupted tooth and is often mistaken for a dentigerous cyst. Histopathologic examination demonstrates cuboidal or spindle-shaped epithelial cells forming aggregates or rosette-like structures with minimal connective tissue, and cuboidal or low columnar cells forming glandular duct-like structures. Treatment is complete enucleation, and recurrences are rare. We presented a case of AOT in a 14-year-old male presenting as a cystic mass around an unerupted tooth.- - - - - - - - - - ranking = 1.6666666666667keywords = dentigerous cyst, dentigerous (Clic here for more details about this article) |
6/13. Cystic variant of calcifying epithelial odontogenic tumor.Calcifying epithelial odontogenic tumor (CEOT) is a benign, locally aggressive odontogenic neoplasm characterized by sheets and nests of epithelial cells with deeply eosinophilic or occasionally clear cytoplasm, calcifications, and eosinophilic amorphous material that stains positive for amyloid. Although many cases of CEOT are associated with impacted teeth and occasionally appear radiographically as dentigerous cysts, a true cystic variant has not been previously reported. We report a 15-year-old white male with a large cystic maxillary lesion that filled most of the left maxillary sinus. It deformed the medial wall, the inferior orbital floor, and caused narrowing of the left inferior meatus. Histologically, the cystic lining showed characteristics of CEOT. An intraluminal component that featured histologic characteristics of CEOT was identified during surgery. The lesion was enucleated and the postsurgical course of the patient was uneventful. Because follow-up has been for less than 1 year, a meaningful long-term prognosis cannot be determined at present. However, the patient has not reported any symptoms or signs of recurrence during the follow-up period.- - - - - - - - - - ranking = 0.33333333333333keywords = dentigerous cyst, dentigerous (Clic here for more details about this article) |
7/13. dentigerous cyst of the maxilla and its image diagnosis.Dentigerous cysts may grow unnoticed to such extensive sizes as to occupy a considerable portion of the maxillary sinus. As they enlarge, the bony walls overlying the cysts thin out giving rise to an egg shell sensation upon palpation. Three cases of such extensive dentigerous cysts were experienced since 1987. These three cases were used to illustrate the advantages and disadvantages of the following imaging techniques in the preoperative evaluation of these cysts, conventional radiographs, sonography, CT, and MRI.- - - - - - - - - - ranking = 0.33333333333333keywords = dentigerous cyst, dentigerous (Clic here for more details about this article) |
8/13. Calcifying epithelial odontogenic tumour associated with dentigerous cyst.A case of calcifying epithelial odontogenic tumour is described. Provisional diagnosis based on the radiographical and clinical observations was that of a dentigerous cyst. Microscopical examination revealed features similar to that of CEOT in addition to the epithelial cyst lining.- - - - - - - - - - ranking = 1.6666666666667keywords = dentigerous cyst, dentigerous (Clic here for more details about this article) |
9/13. Ameloblastic fibroma--a case report.An unusual case of ameloblastic fibroma involving two supernumerary teeth in the anterior part of maxilla has been presented here. The radiographic picture mimics a dentigerous cyst where there is a gross migration of one of the involved super-numerary tooth. After the histopathological diagnosis, the lesion was treated with enucleation and curettage.- - - - - - - - - - ranking = 0.33333333333333keywords = dentigerous cyst, dentigerous (Clic here for more details about this article) |
10/13. dentigerous cyst with oro-antral fistula.A dentigerous cyst of the upper jaw is a common disease, forming 3 per cent of all alveolar cysts.
