DENTAL TRIBUNE The World’s Dental Newspaper · US Edition Dental Tribune U.S. Edition | February 2013 NEWS Ad Taking inspiration from nature, scien- tists are reporting an advance toward pre- venting the tooth sensitivity that affects millions of people around the world. Their report on development of the substance, similar to the adhesive that mussels use to attach to rocks and other surfaces in water, appears in the American Chemical Society journal,ACSAppliedMaterials&Interfaces. Quan-Li Li, Chun Hung Chu and col- leagues explain that about three out of every four people have teeth that are sensitive to hot, cold, sweet or sour foods and drinks. It occurs when the hard outer enamel layer on teeth and the softer un- derlying dentin wear away, stimulating the nerves inside. Some sugar-free gums and special toothpastes can help reduce such tooth hypersensitivity. However, Li and Chu cite the need for substances that re- build both enamel and dentin at the same time. To meet that challenge, they turned to a sticky material similar to the adhesive that mussels use to adhere to surfaces. They reasoned that it could help keep min- erals in contact with dentin long enough for the rebuilding process to occur. They describe laboratory tests that in- volved bathing human teeth with worn- away enamel and dentin in liquid contain- ing the sticky material and minerals. Teeth bathed in the sticky material and minerals reformed dentin and enamel. However, teeth bathed just in minerals reformed only enamel. The gooey substance “may be a simple universal technique to induce enamel and dentin remineralization si- multaneously,” they concluded. The authors acknowledge funding from a National Natural Science Foundation of Gooey bath remineralizes teeth China Research Grants Council grant, the Outstanding Youth Fund, from the board of education of Anhui province and the Youth Foundation of the Anhui Provincial Natural Science Foundation.
