Dental Fillings That Kill Bacteria and Re-Mineralize the Tooth

From the 26 April Science Daily article

ScienceDaily (May 1, 2012) — Scientists using nanotechology at the University of Maryland School of Dentistry have created the first cavity-filling composite that kills harmful bacteria and regenerates tooth structure lost to bacterial decay.

Rather than just limiting decay with conventional fillings, the new composite is a revolutionary dental weapon to control harmful bacteria, which co-exist in the natural colony of microorganisms in the mouth, says professor Huakun (Hockin) Xu, PhD, MS.

“Tooth decay means that the mineral content in the tooth has been dissolved by the organic acids secreted by bacteria residing in biofilms or plaques on the tooth surface. These organisms convert carbohydrates to acids that decrease the minerals in the tooth structure,” says Xu, director of the Division of Biomaterials and Tissue Engineering in the School’s Department of Endodontics, Prosthodontics and Operative Dentistry…..

Where do our wasted health dollars go to?

From the 29 April 2012 article at Kevin

The biggest problem with health care delivery in the US is cost, which seems to have taken a back seat to other issues meant to be addressed by health care reform. We spend about $2.5 trillion dollarsa year on health care—that’s over eight thousand dollars a year for every man, woman, and child. What’s that getting you?

According to the government, about 30% goes to hospitals; 20% goes to doctors and other clinicians, 10% goes for prescriptions, and the other 40% or so goes for “other spending,” mostly administrative costs and haircuts for insurance executives. But it’s probably even worse than that: according to arecent JAMA study, about 20% of total healthcare expenditures are wasted dollars.

20% of 2.5 trillion dollars, by the way, is 500 billion dollars. Each year. The JAMA article breaks down the waste into several categories:..

A group of nine medical specialty societies recently announced the “Choose Wisely” campaign, targeting 45 commonly performed medical procedures and tests that offer little or no value in improving health. These interventions waste precious health care resources, lead to erroneous conclusions and/or false security, spur unwarranted additional interventions, and cause patient harm. Among the appropriately indicted procedures was cardiac stress testing of asymptomatic, low-risk patients. There is an old adage among savvy clinicians: “It is difficult to make an asymptomatic person feel better.” Attempting to do so can cause more harm than good.
