1/34. basal cell nevus syndrome. A case report.An 11-year-old boy with multiple dentigerous cysts in the maxilla and mandible is described. Other findings seen in the face, plantar skin, skeletal system and oral cavity indicated the lesions to be due to the basal cell nevus syndrome. This was further confirmed by the presence of similar abnormalities in his father and brother.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/34. Case report of a pigmented dentigerous cyst and a review of the literature on pigmented odontogenic cysts.This paper reports the first case of a dentigerous cyst containing melanin-pigment and melanocytes in the lining epithelium, and the first case of a odontogenic cyst with macroscopically visible pigmentation in the cyst wall. The patient was a 29-year-old Japanese male with a cystic lesion in the left retromolar area of the mandible. Pathologic examination revealed the lesion to be a dentigerous cyst with or without mild surface keratinization, and numerous granules of melanin-pigment were distributed in the basal cells of the epithelial lining. Furthermore, dendritic melanocytes were scattered in the basal layer. review of the literature revealed that pigmented odontogenic cysts are uncommon, and only 11 cases have been documented; eight were odontogenic keratocyst, one was a gingival cyst, one was a botryoid odontogenic cyst, and one was a lateral periodontal cyst. The possible origin of melanocytes in odontogenic lesions is discussed.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
3/34. Follicular or dentigerous (tooth-containing) cyst in the premaxilla of an otherwise edentulous 65-year-old man.A unilocular follicular or dentigerous cyst (FDC) with a diameter of 12 mm was observed incidentally in the premaxilla of a midsagittal section of the head of a 65-year-old cadaver. The mucosal lining of the cyst was grey in color and granular in texture: the osseous walls had a thickness of less than 1 mm. In the floor of the cyst, a slender, fully developed incisor tooth was fixed in a horizontal position. The alveolar processes of the maxilla and mandible were completely edentulous. Postmortem computer tomography showed the cyst in an osteolytic lesion of the premaxilla, and histology revealed a lining of non-keratinized stratified squamous epithelium supported by a lamina propria of dense connective tissue. copyright Wiley-Liss, Inc.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
4/34. Spontaneous regression of bilateral dentigerous cysts associated with impacted mandibular third molars.A case is described where a routine panoramic radiograph revealed radiolucencies, compatible with dentigerous cysts, associated with the crowns of bilateral impacted lower third molars. Both cysts had regressed in a follow up radiograph three years later with no intervention. This is the first reported case of spontaneous regression of bilateral dentigerous cysts.- - - - - - - - - - ranking = 0.0015493295967076keywords = lower (Clic here for more details about this article) |
5/34. Primary intraosseous carcinoma associated with impacted third molar of the mandible: review of the literature and report of a new case.This study investigated the clincopathologic features of primary intraosseous carcinoma (PIOC) related to the third molar of the mandible. Six cases (5 from the literature and 1 new case; mean patient age 73 years) of PIOC associated with completely impacted lower third molar were analyzed. For comparison, 8 cases of PIOC presenting after extraction of the lower third molar were also evaluated, with a significantly lower mean patient age of 56 years. Most lesions were deceptively similar to those related to the lateral type of dentigerous cyst, and half of the impacted cases revealed an asymptomatic fracture of the mandible. In all patients except for the present case, metastasis had not been recorded. Surprisingly, no patients are known to have died of PIOC. In our experience the prognosis of PIOC associated with a completely impacted third molar is much better than commonly believed, although the number of cases involved is too small to make a general conclusion. However, delay in establishing the correct diagnosis followed by extraction without awareness of the carcinoma is know to adversely affect the prognosis.- - - - - - - - - - ranking = 6.0046479887901keywords = mandible, lower (Clic here for more details about this article) |
6/34. Squamous cell carcinoma arising in a dentigerous cyst in a 16-month-old girl.Squamous cell carcinoma arising in a dentigerous cyst is a rare lesion with distinct histopathology and stringent criteria for diagnosis.(1,2) During the past century, <60 cases have been reported.(3) Of the previously documented cases, all have occurred in adults. We present the case of a squamous cell carcinoma arising in a dentigerous cyst in a 16-month-old girl. This case poses interesting questions regarding the pathophysiology of these tumors and highlights the importance of maintaining a high index of suspicion regardless of age when evaluating cystic lesions of the mandible and maxilla.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
7/34. Bilateral maxillary dentigerous cysts: a case report.Dentigerous cysts are benign odontogenic cysts that are associated with the crowns of permanent teeth. They are usually single in occurrence and located in the mandible. Multiple cysts are reported in patients with conditions such as mucopolysaccharidosis and basal cell nevus syndrome. We present the radiologic findings of bilateral impacted maxillary cuspids with dentigerous cysts displacing the maxillary sinuses in a nonsyndromic patient, a condition that, to our knowledge, has not been previously reported.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
8/34. Case report of dentigerous cyst of lower incisor.This paper reviews the pathogenesis, clinical features and the behaviour of dentigerous cyst. A case of mandibular dentigerous cyst involving the incisor tooth (an unusual site) is presented to illustrate this pattern of behaviour. A recurrent pyogenic granuloma in the region of the lower incisors prevented the eruption of the lower left incisor with subsequent cystic formation around the tooth. The histological and radiological presentation is consistent with that of a dentigerous cyst. The significance of the potential of the cyst lining is stressed. The cyst was enucleated with the associated tooth as the latter was not in a favourable position to erupt. There was no recurrence after one year of treatment.- - - - - - - - - - ranking = 0.0092959775802458keywords = lower (Clic here for more details about this article) |
9/34. Irrigational therapy of a dentigerous cyst in a geriatric patient: a case report.Dentigerous cysts are recognized as one of the most common lesions of the jaws. Although surgical enucleation is usually the preferred treatment method, it is not always the best choice for elderly patients who have other medical complications. With cyst irrigational therapy, repeated irrigation allows bone regeneration around the cyst to progress more rapidly than that around a cyst treated operatively with marsupialization. We used irrigational therapy to treat a dentigerous cyst in a 72-year-old man who did not agree to surgery because he had no symptoms associated with the cyst, and he had other medical complications. After one year, remarkable bone regeneration was observed. We conclude that irrigational therapy appears to be an effective, less-invasive alternative to surgery for geriatric patients.- - - - - - - - - - ranking = 0.099578590395222keywords = jaw (Clic here for more details about this article) |
10/34. Adenomatoid odontogenic tumor: a report of an unusual maxillary lesion.Adenomatoid odontogenic tumor is an odontogenic tumor that appears in the anterior portion of the jaws and more frequently, in the anterior maxilla usually in association with the crowns of inclused teeth. A case report of adenomatoid odontogenic tumor with an associated impacted right maxillary first premolar is presented. Under general anesthesia the lesion and the impacted tooth were removed. There was no recurrence at the 1 -year follow-up.- - - - - - - - - - ranking = 0.099578590395222keywords = jaw (Clic here for more details about this article) |
