  • Publication number: 20230022721
    Abstract: Compositions and methods for inhibiting and interrupting biofilm formation, and for destabilizing established biofilms are provided, the novel compositions including polymeric resins and monomeric non-polymerizable and polymerizable resins. More particularly, the compositions and methods enable the protection and removal of biofilms from surfaces in the context of medical, consumer, domestic, food service, environmental and industrial applications, where the effects constitute beneficial and desirable biofilm attenuating activity.

  • Patent number: 10780026
    Abstract: A method of forming a dental composite includes photopolymerizing a dental composition. The dental composition includes a free-radically polymerizable (meth)acrylate resin, 75 percent by weight or greater of filler particles, and about 0.005 percent to about 5 percent by weight of at least one polymerizable stable radical. The photopolymerizing forms the dental composite such that the dental composite has a flexural modulus of about 9500 MPa or greater and the polymerizable stable radical reduces shrinkage stress of the dental composite caused by the photopolymerizing by 10% or greater. A method of forming a dental composite composition includes combining a free-radically polymerizable (meth)acrylate resin, 75 percent by weight or greater of filler particles, and about 0.005 percent to about 5 percent by weight of at least one polymerizable stable radical to form the dental composite composition.

  • Patent number: 9931280
    Abstract: A dental composite composition is disclosed that includes a polymerizable resin, filler particles, and at least one polymerizable stable radical. A variety of polymerizable stable radicals may be employed, including those that have a 2,2,6,6-tetramethylpiperidinyl-1-oxyl moiety. Compositions as described herein exhibit excellent mechanical strength, hardness, and flexural modulus, while also significantly decreasing shrinkage stress caused by polymerization.
