8263681 Dental compositions with natural tooth fluorescence September 11, 2012
The invention features a dental composition containing a polycyclic aromatic compound, such as 2-ethyl 9,10-dimethoxy anthracene (EDMOA), in an amount that provides the composition with fluorescence mimicking that of natural teeth.
8076389 Adhesive composition for hard tissue December 13, 2011
An adhesive composition including an etchant for a hard tissue surface, at least one multifunctional crosslinkable (meth)acrylate monomer with a functionality greater than 4, and water. The adhesive composition is a water-in-oil emulsion.
8071662 Dental compositions with surface-treated filler for shelf stability December 6, 2011
The invention features dental compositions containing a basic filler that has been surface-treated with a strong acid to increase the shelf life of the composition.
8029286 Self-etching dental compositions and methods October 4, 2011
The present invention is directed to dental compositions that can be used as adhesives for bonding a dental material to a dental structure surface and/or as a dental restorative material. The dental composition is preferably applied to a dental structure surface under conditions effe
7632098 Self-adhesive dental compositions and methods December 15, 2009

7393882 Dental pastes, dental articles, and methods July 1, 2008
The present invention provides a dental paste, a dental article, methods of making and using the dental paste, and compositions prepared therefrom. In one embodiment, the dental paste includes (a) a filler including porous, non-pyrogenic silica having a silane treated surface and bei
7134875 Processes for forming dental materials and device November 14, 2006
Processes for forming dental materials that include applying a first hardenable dental composition (e.g., a dental adhesive) to a surface followed by applying a second hardenable dental composition (e.g., a dental composite) to the first hardenable dental composition on the surface.
7090721 Use of nanoparticles to adjust refractive index of dental compositions August 15, 2006
The present invention features ionomer compositions containing nanofillers that provide the composition with desirable aesthetic properties (e.g., optical translucency). The compositions can be used in a variety of dental and orthodontic applications, for example, as adhesives, cements,
6773261 Processes for forming dental materials August 10, 2004
Processes for forming dental materials that include applying a hardenable dental adhesive to a surface and a second hardenable dental composite to the dental adhesive. The hardenable dental composite includes at least two adjacent regions with different concentrations of a photoinitiator
