Advanced Gum Disease May Raise Cancer Risk
from WebMD
Taking care of your teeth and gums may not only save your smile, it could save your life. A new study suggests a common form of gum disease may significantly raise the risk of head and neck cancer. Researchers found that people diagnosed with head and neck cancers were much more likely to have chronic periodontitis than people without cancer. Periodontitis is advanced gum disease that leads to progressive loss of bone and soft tissue that surround the teeth. More

Oral Biofilms: The "Balancing Act"
from Inside Dental Assisting
It has been said that the mouth is a petri dish. There is a coating of bacteria, viruses, and fungi covering all of the soft and hard tissues in the mouth. This coating may be thick, as can be seen with dental plaque, or invisible, such as in the normal oral mucosa. Rather than acting like bacteria or other organisms which are planktonic, or free-floating and non-adherent, these organisms clump together to form a very sticky biofilm. More

Risk from Mercury in 'Silver' Fillings Still Prompts Dental Debate
from The Plain Dealer
In 2005 alone, dentists in the United States plugged 52 million holes in our teeth with a material commonly known as "silver"-- a material that, despite the name, is mostly mercury. There is no question that mercury, a heavy metal, is toxic in large doses. It can cause memory impairment; itching; burning; pain; tissue swelling; loss of hair, teeth and nails; kidney dysfunction; and psychiatric problems. More

Oral Bacteremia as a Cause of Prosthesis Failure in Patients with Joint Replacements
from the Journal of Oral and Maxillofacial Surgery
Loss of a total joint replacement is a serious, potentially devastating outcome and its prevention needs to be paramount. One of the principle means of preventing failure of total joint arthroplasty is to prevent bacterial infection of the prosthesis. Despite their rarity, these oral-sourced infections have produced an outsized interest among orthopedists and dentists. More

How to Manage Dental Costs, With or Without Insurance
from The New York Times
Much has been said and written about the tens of millions of Americans without health insurance. But often overlooked in these discussions is another vital medical statistic: more than 100 million Americans go without dental coverage. More

Possible Biomarkers for Root Resorption in People with Braces
from U.S. National Institute of Dental and Craniofacial Research
Braces come in all makes and models - stainless steel, nickel titanium, ceramic, clear plastic. You name it. And yet, the underlying biology of tooth realignment remains essentially the same. Braces are attached directly to the crowns of the teeth, resulting in stresses along the tooth roots and within the rope-like periodontal ligaments that tether teeth to bone. That’s where the biology kicks in. The periodontal ligament, strained to accommodate the stress, alters its normal blood flow, allowing specialized cells to dissolve bone in the tooth socket and gradually move the tooth away from the pressure.
