(9of11)United States Patent Application20070202342Kind CodeA1Whiteford; Jeffery A. ; et al.August 30, 2007Methods and systems for coating an oral surfaceAbstractAn antimicrobial coating system and method are described. In some embodiments, a system may include a composition. The composition may include one or more bridged polycyclic compounds. At least one of the bridged polycyclic compounds may include at least two cyclic groups, and at least two of the cyclic groups may include quaternary ammonium moieties. In some embodiments, a method may include applying an antimicrobial coating to an oral surface, a surface of a construction substrate, a surface of a marine substrate, a surface of a medical device, or a surface of a personal care device. The protective coating may be antimicrobial. A protective coating may include antimicrobial bridged polycyclic compounds. Bridged polycyclic compounds may include quaternary ammonium compounds. Bridged polycyclic compounds based coating systems may impart self-cleaning properties to a surface (e.g., a tooth surface).Inventors:Whiteford; Jeffery A.;(Belmont, CA); Freeman; William P.;(San Mateo, CA)Correspondence Address: MEYERTONS, HOOD, KIVLIN, KOWERT & GOETZEL, P.C.

(canceled)225. A method of coating an oral surface, comprising: applying a composition to at least a portion of an oral surface, the composition comprising one or more bridged polycyclic compounds, at least one of the bridged polycyclic compounds comprising at least two cyclic groups, wherein at least two cyclic groups are defined in part by quaternary ammonium moieties; and forming an antimicrobial coating over at least a portion of the surface.226. The method of claim 225, wherein at least one of the bridged polycyclic compounds comprises at least four quaternary ammonium moieties which define at least two of the cyclic groups forming the bridged polycyclic compounds.227. The method of claim 225, wherein at least one of the quaternary ammonium moieties defining at least one of the cyclic groups further comprises an alkyl group, a substituted alkyl group, an aryl group, a heterocycle group, a substituted heterocycle group, or a substituted aryl group.228. The method of claim 225, wherein at least one of the quaternary ammonium moieties defining at least one of the cyclic groups further comprises an alkyl group, a substituted alkyl group, an aryl group, or a substituted aryl group and an alkyl group, a substituted alkyl group, an aryl group, or a substitute
