Abstract
Coatings for hard tissue and surfaces of the oral environment are provided that reduce adhesion of bacteria and proteinaceous substances to these surfaces. Methods of reducing adhesion of these materials to such surfaces, and polymers for incorporation into such coatings are also provided.
Claims13
A coating on hard tissue surfaces or surfaces of the oral environment, which coating comprises a polymer that is less than 0.1 percent soluble in water comprising repeating units
- A) 1-80% by weight of a polar or polarizable group
- B) 0-98% by weight of a modulating group
- C) 1-40% by weight of a hydrophobic fluorine-containing group, wherein said coating has a Wilhelmy Balance Test Advancing Contact Angle greater than 55.degree..
