1/91. Fibrodysplasia ossificans progressiva and associated osteochondroma of the coronoid process in a child.The article reports the occurrence of osteochondroma in a fibrodysplasia ossificans progressiva patient. A 5-year-old boy presented with limited mouth opening and firm swelling of the right zygomatic complex area. The boy had bilateral hallux valgus of the great toes and heterotopic endochondral ossification of facial and neck regions. Associated osteochondroma of the coronoid process and aggressive heterotopic ossification of masticatory and neck muscles were found in response to traumatic injuries. Natural and clinical histories of fibrodysplasia ossificans progressiva were reviewed. An early diagnosis and avoidance of factors that aggravate ossification are key factors in reducing the expected degree of physical disabilities of patients. An early recognition of congenital skeletal deformities, early detection of abnormal ossification, and awareness of the disease by the involved physicians are important factors in the early diagnosis of the disease and in reducing any unnecessary trauma. Bone scintigrams and CT scans are effective noninvasive tools for an early detection of ossification and for monitoring the progression of the disease. Further investigation of its pathogenesis at a molecular level is important to understand better the nature of the disease and to develop an effective treatment protocol.- - - - - - - - - - ranking = 1keywords = process (Clic here for more details about this article) |
2/91. ameloblastoma of the maxilla. Case report.A basal cell maxillary ameloblastoma became obvious as an asymptomatic swelling of the left buccal sulcus and alveolar process, although a large extension into the maxillary sinus up to the nasal conchae and the orbital floor had already occurred. The painless and slow growth of the lesion, the thin bone of the upper jaws, the adjacent cavities and the vital structures are the main factors for delay in recognition and thus the potentially lethal result of a maxillary ameloblastoma. A review of location, age, sex and race predilection, clinical course, radiographic appearance, histological types and treatment methods in made.- - - - - - - - - - ranking = 5182.0535036231keywords = alveolar process, alveolar, process (Clic here for more details about this article) |
3/91. Prosthetic restoration following maxillary resection without an oroantral defect: a case report.PURPOSE: The aim of this article was to present the oral rehabilitation of a patient with a large, created intraoral defect after the surgical extirpation of a pathologic process. MATERIALS AND methods: On osseointegrated oral implants, a bar was fabricated to support a partial overdenture by means of attachments. RESULTS: The treatment was successful and the construction has been in service for more than 5 years. CONCLUSION: In cases with large intraoral defects removable dentures may have clinical advantages over fixed partial dentures. In this patient the restoration of missing teeth, alveolar crest, and soft tissue was accomplished at the same time oral function was restored, and good oral hygiene access was obtained.- - - - - - - - - - ranking = 25.78641586139keywords = alveolar, process (Clic here for more details about this article) |
4/91. Burkitt's lymphoma presenting with jaw lesions.We report an unusual case of Burkitt's lymphoma (BL) presenting with jaw lesions in a 14-year-old Chinese boy. The patient presented initially with mobile teeth in all 4 jaw quadrants, with corresponding radiographic detection of alveolar bone crest destruction and periapical bone resorption in the absence of clinically detectable jaw tumors. Moreover, radiographs taken only 17 days later showed clearly distinguishable signs of more extensive alveolar bone destruction compared with the initial radiographs.- - - - - - - - - - ranking = 51.17283172278keywords = alveolar (Clic here for more details about this article) |
5/91. The amyloid deposit in calcifying epithelial odontogenic tumor is immunoreactive for cytokeratins.Calcifying epithelial odontogenic tumor, also known as Pindborg tumor, is a rare benign tumor with locally aggressive behavior. It is characterized by squamous epithelial cells, calcifications, and eosinophilic deposits that have been identified as amyloid. We report a case of calcifying epithelial odontogenic tumor and investigate the nature of the amyloid, using histologic, immunohistochemical, and ultrastructural studies. The amyloid was immunohistochemically negative for basement membrane components and positive for all cytokeratin stains performed (cocktail of cytokeratins 1, 5, 6, 8, 13, and 16, and cytokeratins AE1 and AE3). The amyloid stained focally in a glandular-like pattern, reminiscent of the epithelial glandlike structures of the tumor. We conclude that the amyloid is derived from filamentous degeneration of keratin filaments that originate from the tumor squamous epithelium. The keratin degeneration is part of a developmental or aging process that the tumor undergoes.- - - - - - - - - - ranking = 0.2keywords = process (Clic here for more details about this article) |
6/91. Treatment of giant cell granuloma of the maxilla with intralesional injection of steroids.BACKGROUND: Giant cell granuloma is rare in the head and neck region and most commonly affects the maxilla and mandible. Although it is a benign disease process, it may be locally destructive. Surgery is the treatment currently recommended. Because of the location of the disease, surgery may be disfiguring. Because it is a benign process, less radical nonsurgical treatment alternatives are desirable. methods: A case report of a giant cell granuloma treated with steroid injections. RESULTS: After six weekly intralesional steroid injections, a giant cell granuloma of the maxilla became calcified and smaller. After a follow-up period of 2 years, there was no evidence of regrowth, and the bony osteolytic lesion had filled with bone. A review of the literature revealed two case reports of successful steroid injections with similar response. CONCLUSIONS: Steroid injections are a viable alternative in the treatment of giant cell granuloma, which may avoid surgery.- - - - - - - - - - ranking = 0.4keywords = process (Clic here for more details about this article) |
7/91. Restorative dentistry using a multidisciplinary approach.Multidisciplinary treatment was essential for this patient to optimally manage the occlusion and missing teeth. When the space distribution was completed, ridge management procedures for pontic site development were accomplished. The final restorative treatment required was actually minimized to a 7-unit fixed partial denture. It was apparent the multidisciplinary treatment was essential to predictably manage this patient by decreasing risk and ensuring a long-term strategy for enhanced patient satisfaction.- - - - - - - - - - ranking = 20.587026884786keywords = ridge (Clic here for more details about this article) |
8/91. Reconstruction of the orbital floor after its removal for malignancy.Reconstruction of the orbital floor for malignant disease can be difficult. The tissue used should replace the floor itself and the orbital rim to ensure appropriate positioning of the globe and to avoid ectropion. The authors present a simple technique using temporalis muscle with attached coronoid process of the mandible that covers both these areas, and which is suitable for most defects in this area.- - - - - - - - - - ranking = 0.2keywords = process (Clic here for more details about this article) |
9/91. Bilateral hyperplasia of the mandibular coronoid processes associated with the nevoid basal cell carcinoma syndrome in an Italian boy.In this report we present a subject affected by nevoid basal cell carcinoma syndrome (NBCCS), showing also bilateral mandibular coronoid processes hyperplasia, a hitherto unreported association. Our observation of bilateral hyperplasia of the mandibular coronoid processes in a boy with NBCCS may prompt a retrospective and prospective review of other patients affected by this syndrome in order to establish if this anomaly is part of it.- - - - - - - - - - ranking = 1.2keywords = process (Clic here for more details about this article) |
10/91. Radiographic evaluation of malignant fibrous histiocytoma affecting maxillary alveolar bone: a report of 2 cases.OBJECTIVE: The purpose of this study was to evaluate the radiographic findings of malignant fibrous histiocytoma (MFH) and to discuss the contribution of these findings to a differentiation of MFH from other malignant tumors of the head and neck. STUDY DESIGN: Two cases of MFH of the maxillary sinus affecting the alveolar bone were evaluated radiographically and scintigraphically. RESULTS: We reported the following findings, which have only seldom been described: the presence of fairly well-demarcated bone destruction in the intraoral radiograph; the relatively smooth surface, uniform density, or no necrotic area of the tumor; in computed tomograph images showing the clear separation of the tumor from surrounding soft tissues; bone scintigraphs reflecting the periosteal reaction to tumor invasion; and lymphoscintigraphy of the metastatic lymph nodes. CONCLUSION: We evaluated the radiographic findings from 2 cases of MFH and describe findings that may aid in the differentiation of MFH. These radiographic features may help dentists differentiate MFH from other malignant tumors in the head and neck, although MFH is a rare disease and there are no radiographic findings that would indicate a specific diagnosis of MFH.- - - - - - - - - - ranking = 127.93207930695keywords = alveolar (Clic here for more details about this article) |
