Zimmer Dental has released the Puros Cortico-Cancellous particulate allograft, an anatomic-based mixture of cortical and cancellous bone designed to simplify the grafting process. Composed of 70% cortical and 30% cancellous bone, Puros Cortico-Cancellous does not require on-site mixing, and retains its osteoconductive properties due to the preservation of the natural bone matrix collagen and mineral composition, trabecular pattern, and original porosity, the company said in a press release.

A group of Chinese and Australian scientists has developed a handheld, 12 volt-battery-powered, plasma-producing device that can instantly kill harmful bacteria in the oral cavity and other tissue. In an experiment, the flashlight inactivated a thick biofilm of one of the most antibiotic- and heat-resistant bacteria, Enterococcus faecalis — a bacterium that often infects the root canals during endodontic treatments (Journal of Physics D: Applied Physics, April 5, 2012). The
Researchers from the University of Sheffield and Rice University are developing a new “lab on a chip” technique they say can diagnose oral cancer more quickly and effectively. The device, which is undergoing a clinical trial led by Martin Thornhill, BDS, PhD, professor of oral medicine at the University of Sheffield, could be used by a dentist to determine whether a patient has oral cancer or other abnormalities in fewer
As part of Oral Cancer Awareness month, the California Dental Hygienists’ Association (CDHA) is working to educate patients and practitioners about the link between acid reflux and the potential for esophageal cancer.

Global Grins, a California nonprofit that delivers toothbrushes to impoverished and disadvantaged people worldwide, has donated 100,000 toothbrushes to a U.S. Navy mission. The USNS Mercy departs San Diego in April on the Pacific Partnership humanitarian mission to Vietnam, Cambodia, the Philippines, and Indonesia.

The Academy of General Dentistry (AGD) has joined the ADA and the American Academy of Pediatric Dentistry in voicing concerns over the latest report from the W.K. Kellogg Foundation supporting dental therapists. In a statement issued April 10, the AGD contended that the Kellogg report “is presented in the context of a political movement,” not in the context of what is in the best interest of the American people and
A Texas dentist who specializes in oncology has seen his practice grow quickly as cancer patients struggle with the side effects of chemotherapy and radiation treatment. Some 1.6 million new cases of cancer are diagnosed annually, and approximately 12 million people are living with cancer, according to the National Cancer Institute (NCI). While more cancer patients are surviving due to advanced chemotherapy and radiation treatments, the therapy often causes oral

Plasma-rich growth factor (PRGF) can aid in the surgical management of cancer patients on bisphosphonate therapy who require a tooth extraction, according to a new study in Oral Oncology. For cancer patients who undergo intravenous (IV) bisphosphonate therapy, dental extraction is the main cause of bisphosphonate-related osteonecrosis of the jaw (BRONJ), the researchers noted (Oral Onc, April 5, 2012). A team of Italian researchers conducted a case-control study on 176
