Orthokeratinized Odontogenic Cyst: Case of a Rare Peripheral Counterpart.

In this paper, we describe a case of a 57-year-old male with an orthokeratinized odontogenic cyst (OOC), which presented as a diffuse, asymptomatic swelling located on the left posterior aspect of the mandible that together with radiographic and histopathologic findings was diagnosed as a peripheral OOC.

Oral and maxillofacial radiologists: career trends and specialty board certification status.

Oral and maxillofacial radiology is the newest specialty to be recognized by the American Dental Association, so knowledge about the parameters of this profession is in the early stages of development. The aim of this study was to understand the current distribution of oral and maxillofacial radiologists (OMFRs) in academia and private practice, the nature of their practice, and trends in their board certification status. An email describing the study's purpose with a link to a survey was sent to "OradList," a listserv that has a majority of OMFRs in the United States and Canada as members.

Using hand-held dental x-ray devices: ensuring safety for patients and operators.

Background: Since the introduction of hand-held x-ray units in dentistry, a few inexpensive devices have emerged that lack the necessary safety measures and failed to meet U.S. Food and Drug Administration (FDA) standards.

Estrogen induces lung metastasis through a host compartment-specific response.

Direct proliferative effects of estrogen (E(2)) on estrogen receptor-positive tumors are well documented; however, the potential for E(2) to mediate effects selective for the host (i.e., angiogenesis, vascular permeability, or stromal effects), which influence tumor growth and/or metastasis, has received less attention.

Reduced glioma infiltration in Src-deficient mice.

Malignant brain tumors, such as glioblastoma, are characterized by extensive angiogenesis and permeability of the blood-brain barrier (BBB). The infiltration of glioma cells away from the primary tumor mass is a pathological characteristic of glial tumors. The infiltrating tumor cells represent a significant factor in tumor recurrence following surgical debulking, radiation, and chemotherapy treatments.
