Accuracy of diagnoses of HIV-related oral lesions by medical clinicians. Findings from the Women's Interagency HIV Study.

Objective: To determine if medical clinicians are as accurate as dental clinicians in recognizing diagnostic characteristics of HIV-related oral lesions.

Methods: In 355 HIV-infected participants at five Women's Interagency HIV Study sites, we paired oral examinations conducted within 7 days of each other by dental and medical clinicians. We used the former as a gold standard against which to evaluate the accuracy of the latter.

Sinus histiocytosis with massive lymphadenopathy: report of case.

A case of a five-year-old African American female with sinus histiocytosis with massive lymphadenopathy is presented. The epidemiology, morbidity, and management aspects of this condition are discussed.

Cortical defects in the mandibular sulcus.

Examination of 5366 dry mandibles at the Smithsonian Institution revealed three cases of unilateral lingual defects superior to the mandibular foramen. The differential diagnosis includes a neuroma, neurolemmoma, hemangioma, or aneurysm of the inferior alveolar artery. The clinical significance of a vascular neoplasm or aneurysm would be the likelihood of increasing the risk of injecting the anesthetic solution directly into a blood vessel.

Osseous repair with Le Fort I osteotomy.

The effectiveness of rigid and semirigid fixation at various distances between Le Fort I osteotomy segments after different healing periods was evaluated in 16 Macaca fasicularis monkeys. The histologic findings revealed better healing with semirigid fixation.

The maxillary ameloblastoma: an analysis of 24 cases.

Twenty-four cases of maxillary ameloblastoma from the files of the dental and oral division of the Armed Forces Institute of Pathology and the US Army Institute of Dental Research were reviewed. Clinical findings showed an average age of 45.6 years, a male-to-female ratio of 2.

Light microscopy, scanning electron microscopy, and microprobe analysis of bone response to zinc and nonzinc amalgam implants.

Freshly mixed, unset zinc-free and zinc-containing analgam was implanted in the right tibia of 32 rats. Half of the specimens were examined by the light microscope and the other half by the scanning electron microscope and x-ray microprobe analysis. It was found that amalgam is well tolerated by the rat osseous tissue, and there were no histologic reaction differences between zinc and zinc free amalgam.

The effects of overfilled polyethylene tube intraosseous implants in rats.

Polyethylene tubes obturated flush at one end overfilled 2 mm. at the opposite end with unset Grossman's cement and gutta-percha were implanted in rat tibias. Microscopic evaluation of the specimens revealed that (1) the gutta-percha, Grossman's sealer, and polyethylene tubing are well tolerated by rat intraosseous tissue and (2) a canal overextended 2 mm.

Healing of the oral mucosa with the use of collagen artificial skin.

Wounds were prepared in the oral cavity of 15 rabbits and five dogs, and an enzyme-solubilized calfskin collagen was placed over the surgery sites on one side. The contralateral sides acted as controls. Results indicated that the membrane was biologically acceptable to the oral mucosa of rabbits and dogs.

The effects of partially filled polyethylene tube intraosseous implants in rats.

Polyethylene tubes obturated flush at one end and 1 mm. short at the opposite end with gutta percha and Grossman's cement as the cementing media were implanted in rat tibias. The gutta-percha, the set Grossman's cement, and the polyethylene implant were well tolerated by the rat intraosseous tissues.

Clear-cell sarcoma of tendons and aponeuroses.

The natural history and histologic characteristics of a rare malignant neoplasm of tendons and aponeuroses are described, and a case is presented which originated in the right foot of a 19-year-old Caucasian woman who succumbed to the disease after 4 years. This case represents the first known example of metastasis to the oral cavity of this particular neoplasm.

Pathosis of the hard and soft palate.

In this article a few of the more recently emphasized and pertinent conditions that may affect the hard and soft palate have been discussed. The purpose of the article is not to present in all-inclusive classification of lesions occurring the palate. Disease of the palate may be local in nature or may reflect a systemic condition.

Odontogenic adenomatoid tumor: report of case and review of the literature.

An unusual case of odontogenic adenomatoid tumor in the mandible of an 11-year-old Ethiopian girl is described. This case is unique because of the extensive size of the tumor (12 cm), long duration, the number of associated impacted teeth (seven), the pronounced areas of radiopaqueness, the multiocular configuration, the anomalous tooth form, and the fact that deciduous teeth were involved.

Histologic features of the superior labial frenum.

Histologic examination was performed on the superior labial frenum obtained from 11 fresh biopsy and three autopsy specimens. The frena contained considerable dense collagen, loose connective tissue and elastic fibers. There were no muscle fibers in any of the frenum sections except the autopsy specimens, where it was seen in the vestibular tissue but not in the frenum proper.
