PURPOSE To determine the optimal cutoff level of fluorine-18-labeled fluorodeoxyglucose (FDG) uptake in the differentiation of low-grade from high-grade cerebral tumors at position emission tomography (PET). MATERIALS AND METHODS The authors retrospectively reviewed images from PET, magnetic resonance imaging, and computed tomography performed in 58(More)
The present study was undertaken to evaluate the effect of a twice-daily topical application of a 0.05% NaF mouthrinse on de- and remineralization in the oral cavities of subjects suffering from radiation-induced hyposalivation. Six subjects each wore a bonded intra-oral appliance containing a sound and a demineralized human enamel slab for four weeks.(More)
There is a controversy regarding whether dental treatment before chemotherapy protocols, including hematopoietic stem cell transplantation (HSCT), is helpful to prevent infections during the consequent immunosuppression. The aim of this study was to develop a decision analysis framework that would test the effect of dental treatment prior to chemotherapy on(More)
A patent foramen ovale (PFO) is an embryological remnant found in 27% of adults. It is a potential right-to-left intracardiac shunt. Shunting may be the result of reversal in the interatrial pressure gradient or abnormal streaming of blood in the right atrium. The pathologic consequences of right-to-left shunting include hypoxemia and paradoxical embolism.(More)
INTRODUCTION The purpose of this article is to compare published evidence supporting procedures to prevent dental caries and periodontal disease, in low-risk patients, with the actual preventive recommendations of practicing dentists. METHODS Methods included (1) a survey questionnaire of general dentists practicing in western New York State concerning(More)
Dental caries is one of the most significant health problems facing older adults.

PURPOSE Based on in vivo evidence of radioprotection of the salivary glands using WR-2721, a pilot study was undertaken to determine the feasibility, toxicity, and salivary function of patients receiving WR-2721, while undergoing radiation therapy to the head and neck. METHODS AND MATERIALS Patients undergoing radiation therapy for cancer of the head and(More)
This study was designed to evaluate a system to quantitate vascularity and tumor blood flow with amplitude (power) color Doppler sonography. The vascularity of nine transplanted murine tumors was determined with quantitated amplitude color Doppler sonography and compared to tumor vascularity estimated by histologic examination. The system used seemed to(More)
Academic dentists and members of the practice community have been hearing, for more than a decade, that our educational system is in trouble and that the profession has lost its vision and may be wavering in the achievement of its goals. A core of consistently recommended reforms has framed the discussion of future directions for dental education, but as(More)
