Solitary fibrous tumor with entrapment of minor salivary gland tissue: an unusual presentation that requires exclusion of pleomorphic adenoma.

We report two unusual cases of solitary fibrous tumor (SFT) of minor salivary glands that microscopically mimicked pleomorphic adenoma. One of these lesions presented in the retromolar region and the other in the buccal mucosa. The microscopic features of these two tumors and their intimate relationship with regional mucous minor salivary glands posed a diagnostic challenge.

Full-mouth rehabilitation with single-tooth implant restorations. Overview and report of case.

The purpose of this study was to report a case of full-arch rehabilitation with single-tooth endosseous implant restorations. Secondly, the investigators aimed to review the literature systematically regarding full-mouth rehabilitation of the edentulous patient with single-tooth implant restorations. The investigators searched the databases PubMed, EMBASE Drugs and Pharmacology, the Cochrane library, and clinicaltrials.

Building on the proceedings of the McGill conference: implant-retained overdentures in an area of South America.

Purpose: Since the McGill consensus conference, numerous reports have proposed the advantages of the 2-implant-retained overdenture over the conventional denture in the restorative management of the edentulous mandible. The purpose of this article was to demonstrate the use of the 2-implant-retained overdenture in the restorative management of patients with edentulous mandibles in an impoverished population.

Materials: To address the study's purpose, the investigators initiated a retrospective cohort study and enrolled a sample of subjects who had mandibular 2-implant overdenture treatment using the protocol described within.

Modified channel retractor for the sagittal split ramus osteotomy: a technical note.

The authors describe a modification of the commonly used inferior border channel retractor for the sagittal split osteotomy of the mandible. We modified this instrument by hollowing out the shank and working surface allowing improved access during the vertical cut through the inferior border of the mandible. Advantages of this modification over the original design include less dulling of the cutting instrument, less damage to the channel retractor, less debris in the surgical wound, and most importantly, less damage to the surrounding soft tissue.

Morbidity associated with oral mucosa harvest for urological reconstruction: an overview.

Purpose: To present a systematic review of the literature regarding complications associated with the donor site following oral mucosa harvest for urethral reconstruction.

Materials And Methods: The authors conducted a database search for relevant literature during the time period January 1966 through January 1, 2007, regarding complications associated with oral mucosa graft harvest for use in urethral transplantation. Bibliographies of database hits were searched for pertinent papers.

Draining orocutaneous fistula associated with a failing subperiosteal implant: report of a case.

The use of mandibular subperiosteal implants was first reported by Dahl in the 1940s. It was followed by a more comprehensive report by Goldberg and Gershkoff, who published the first case series in the United States. We describe a case of an orocutaneous fistula that developed secondary to a chronic infection attributed to a failing subperiosteal implant.

The oral mucosa graft: a systematic review.

Purpose: We provide the reader with a critical, nonbiased, systematic review of current and precedent literature regarding the use of oral mucosa in the reconstruction of urethral defects associated with stricture and hypospadias/epispadias.

Materials And Methods: We reviewed pertinent English literature from January 1966 through August 1, 2006 via the databases MEDLINE/PubMed, the Cochrane Library, and EMBASE Drugs and Pharmacology regarding the use of oral mucosa graft urethroplasty in the reconstruction of urethral defects associated with stricture and hypospadias/epispadias. Bibliographies of pertinent articles were explored for additional important literature.

Cavernous hemangioma of the palate. A review of etiology, pathogenesis and treatment options.

Cavernous hemangiomas of the palate are a rare but not infrequent sighting in the oral and maxillofacial region. The etiology and pathogenesis of these lesions are not definitively understood and are currently being explored. Treatment options usually include, but are not limited to, surgical excision of the lesion.

Bisphosphonate-associated osteonecrosis of the jaws: a review of current knowledge.

Background: Increasing numbers of dental patients are taking bisphosphonate medications for a variety of indications. These drugs may be associated with poor healing, spontaneous intraoral ulceration and bone necrosis in the oral and maxillofacial region.

Case Description: The authors describe a case of osteonecroSis of the jaws in a patient receiving long-term bisphosphonate therapy for cancer.

Nicotine induced proliferation and cytokine release in osteoblastic cells.

Smoking has deleterious effects on osteoporosis and periodontitis both characterized by bone loss. Smoking also interferes with the protective effect that hormone replacement therapy (HRT) has on bone loss. Our study investigated two mechanisms by which smoking may affect bone metabolism: nicotine-induced proliferation and nicotine-induced cytokine secretion in osteoblasts.

Platelet-derived growth factor enhancement of two alloplastic bone matrices.

Background: The use of alloplastic matrices that mimic the mineral phase of bone has become a viable alternative to current mainstream therapies in dentistry such as allografts and autogenous grafts. Because alloplastic bone substitutes generally have relatively poor osteogenic properties, analyzing their potential as vehicles to deliver growth factors is an important step in assessing methods to enhance their clinical efficacy. The aim of these studies was to treat beta-tricalcium phosphate (beta-TCP) and calcium sulfate (CaSO(4)) with platelet-derived growth factor (PDGF)-BB to enhance the osteogenic capabilities of these materials.

Engineering a bioactive matrix by modifications of calcium sulfate.

The goal of this study was to define the conditions for the fabrication of a bioactive matrix that induces and supports cell proliferation and tissue regeneration. The proposed hypothesis was that a composite graft could be engineered by the absorption of platelet-rich plasma (PRP) onto calcium sulfate (CS). Evaluation of the biological activity of the engineered grafts was based on osteoblast proliferation studies and scanning electron microscopy (SEM) analyses.
