Grant received to study ethnic differences in pain

Barbara Hastie, Ph.D., a research assistant professor of community dentistry and behavioral science, received a five-year, $805,194 National Institutes of Health grant to study ethnic differences and genetic factors in acute postoperative pain and analgesic response. In addition, Hastie is the recipient of the 2006 “Future Leaders in Pain…

Tiny cellular structure plays big role in mammalian gene regulation

GAINESVILLE, Fla. – University of Florida researchers have discovered a new ingredient in our cellular soup, tiny structures that may lay the groundwork for how new cells form and then function. The structures, dubbed GW bodies by the UF researchers who identified them in mammalian cells, are described in…

UF researchers test drug that could cut orthodontic treatment time in half

GAINESVILLE , Fla. — In the first study of its kind, UniversityofFlorida researchers are testing the power of a natural human hormone to biochemically move teeth faster and less painfully during orthodontic treatment. “Most of orthodontics has traditionally dealt with physics, the biomechanics of applying a force against a…

Practice-based dental research networks receive $75 million

Gainesville, Fla —The National Institutes of Health, National Institute of Dental and Craniofacial Research (NIH/NIDCR) made an April announcement that $75 million in federal funding will be used to establish three dental practice-based clinical research networks. These regional practice-based clinical research networks will investigate with scientific rigor the everyday…

Some rural residents with oral pain wait too long before seeking help

Joseph Riley, Ph.D., M.S. GAINESVILLE, Fla. – Rural residents are nearly twice as likely as their urban counterparts to postpone timely trips to the dentist, seeking help only after they develop a problem and oral pain is severe, University of Florida researchers report.

Live oral bacteria found in arterial plaque

GAINESVILLE, Fla. — Gum disease has been linked to hardening of the arteries for nearly a decade, and scientists have long fingered a gang of oral bacteria as the obvious suspects behind many cases of the vessel-clogging killer.  Now University of Florida researchers have cornered the bacterial ringleaders of gum…

UF researchers map bacterial proteins that cause tooth loss

GAINESVILLE, Fla. — The human mouth teems with millions of enamel-eroding, gum-inflaming microbes. One of these, Porphyromonas gingivalis, is a bacterial homesteader that stakes a claim deep within the spaces between teeth and gums. It’s also the leading cause of tooth loss — secreting proteins that destroy the soft…
