Mussel-like adhesive may help hypersensitivity


New research into  preventing tooth hypersensitivity has looked at the development of the substance, similar to the adhesive that mussels use to attach to rocks and other surfaces in water. A report appears in the journal ACS Applied Materials & Interfaces. They report that bathing human teeth with worn-away enamel and dentine in liquid containing the sticky material and minerals.The researchers, Quan-Li Li and Chun Hung Chu cite the need for substances that rebuild 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 minerals in contact with dentin long enough for the rebuilding process to occur.

They describe laboratory tests that involved bathing human teeth with worn-away enamel and dentin in liquid containing 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 simultaneously," they concluded.
