Scientists in Canada and China are reporting development of a new dental filling material that substitutes natural ingredients from the human body for controversial ingredients in existing `composite,` or plastic, fillings. The new material appears stronger and longer lasting, as well, with the potential for reducing painful filling cracks and emergency visits to the dentist, the scientists say. Their study appears in the current edition of ACS Applied Materials & Interfaces. http://www.physorg.com/news162060563.html Chemistry Wed, 20 May 2009 17:49:57 EST news162060563 (PhysOrg.com) -- Treatment of chronic wounds is a continuing clinical problem and socio-economic burden with diabetic foot ulcers alone costing the NHS £300 million a year.
