Osseointegration of chemically modified sandblasted and acid-etched titanium implant surface in diabetic rats: a histological and scanning electron microscopy study.

Introduction: The aim of this study is to assess the osseointegration of different dental implants surfaces in diabetic rats.

Materials And Methods: In this study, were used 56 male Wistar rats, average weight of 300-350 g. Diabetes was induced by a single intraperitoneal injection of Streptozotocin.

Hemangioma of the parotid gland: case report.

Hemangiomas account for half of the parotid gland tumors occurring in children. After a rapid increase in the first months of life, some of them gradually regress (until complete disappearance) in a period of several years. Hemangiomas that do not regress over time, grow in size (possibly within a short period of time) or develop complications such as intralesional acute bleeding or thrombosis require aggressive therapy: intralesional corticosteroid injection, sclerotherapy.

[Malherbe's calcifying epithelioma--comment on two clinical cases].

Malherbe's calcifying epithelioma (also called trichomatricoma, pilomatrixoma or pilomatricoma) is an uncommon benign cutaneous tumor, which takes the form of a solitary, firm, asymptomatic, slowly growing nodule, developed subcutaneously on the face, neck, or proximal upper extremity. With an incidence of 1/800-1000 cutaneous tumors, pilomatricoma is more common in the first two decades of life, predominantly affecting the women. Multiple locations and associations between this entity and other diseases such as Steinert's myotonic dystrophy or Gardner syndrome have been described in the literature.

[Dermoid cyst of the parotid gland].

Dermoid cyst of the parotid gland is a rare clinical entity. Definitive clinical diagnosis is often difficult to determine preoperatively because of the lack of pathognomonic features. The most frequent location of a parotid dermoid cyst is a triangular area lying above the pinna.

[Generalized gingival enlargement--early clinic manifestation in acute leukemia. Case report].

Leukemia is a hematological disorder arises from a hematopoietic stem cell characterized by a disordered differentiation and proliferation of neoplastic cells. Rapidly forming generalized gingival hyperplasia is usually the first sign of this disease (especially in acute forms). This case report describes a 54-year-old female who presented rapid gingival enlargement in only three weeks time, heralding the presence of acute monocytic leukemia (AML-FAB M5).

[CT exam and 2D and 3D reconstructions in facial tumors diagnosis].

Unlabelled: This study presents the CT imaging of a group of maxillofacial tumors that include benign tumors and primary and secondary malignant processes.

Material And Method: All patients were CT explored with and without intravenous contrast, using specific head and neck protocols.

Results: We studied the topography of the tumors, their impact on neighborhood regions and post-treatment results.

[Lipomas of the oral cavity--a retrospective study].

Unlabelled: Lipomas are the most common soft tissue mesenchymal neoplasms, with 15 to 20% of the cases involving the head and neck region and 1 to 4% affecting the oral cavity. They represent 0.1 to 5% of all benign tumours of the mouth and are usually found as long-standing soft nodular asymptomatic swellings covered by normal mucosa.

[A review of 15 years of experience in using the musculo-mucosal lingual flap].

Material And Method: In the past 15 years (1991-2005) we used the muscular-mucosal lingual flap with posterior pedicle for 82 patients.

Results: The main indication has been the reconstruction of the residual defects after resection of the mucosal mouth floor carcinomas (especially those located in the anterior third of the mouth or with gingival and alveolar invasion) or after resection of the gingival-alveolar mandible carcinomas with invasion of the mouth floor. Deglutition and phonation have been fully recovered at 14 to 20 days post-surgery, with temporary alterations during radiotherapy, due to radiation-induced mucositis.

[The utilization of Dacron as interposition material in the treatment of the temporomandibular ankylosis--retrospective study: 1993-2005].

The treatment of temporomandibular ankylosis, indifferently by anatomoclinical type or etiologic factor (trauma, infection, rheumatism), is exclusively surgical. The frequent indication in the temporomandibular ankylosis of types I and II Topazian remains the neo-articular modeling osteotomy with or without interposition. A clinical and retrospective study of 25 patients diagnosed with temporomandibular ankylosis (unilateral or bilateral) was performed.

[The value of radical surgical treatment in benign symmetric lipomatosis].

Benign symmetric lipomatosis (BSL) is a rare proliferative disorder of the adipose tissue, characterized by symmetrical fat deposits, predominantly in the neck and shoulder area, upper back and arms. This study contains the analyse of a lot of ten patients with BSL, which were surgical treated in our department between 1994-2004. The followed parameters were: sex, age, heredo-collateral antecedents, associated organic diseases, the motivation of medical addressability, the sites of first lesions, the length of evolution before the admission, methods for diagnosis, number of surgical sessions necessary to extirpation of fat deposits, the results of the periodic follow-up examination.
