Abstract: The present disclosure provides a composite material. The composite material includes 20 to 40 weight percent (wt. %) of a polymerizable component; 6 to 40 wt. % of ceramic fibers; and 30 to 70 wt. % of nanoclusters. Each of the ceramic fibers has a diameter and a length, the ceramic fibers having an arithmetic mean diameter of 0.3 micrometers to 5 micrometers, and the length of fifty percent of the ceramic fibers (based on a total number of the ceramic fibers) is at least 10 micrometers and the length of ninety percent of the ceramic fibers is no greater than 500 micrometers. The present disclosure also provides a method of making the composite material. The method includes obtaining components and admixing the components to form a composite material. Further, the present disclosure provides a method of using a composite material including placing a composite material near or on a tooth surface, changing the shape of the composite material near or on a tooth surface, and hardening the composite material. In addition, the present disclosure provides dental products and kits. Hardened composite materials can exhibit high strength.

Abstract: Disclosed herein are curable glass ionomer compositions that include a first paste and a second paste, and methods for using the disclosed compositions. The first paste includes water, a polyacid, and a non acid-reactive filler. The second paste includes water and an acid-reactive filler. At least one of the first paste and the second paste further includes substantially crystalline inorganic fibers. In some embodiments, the water content of the first paste and the second paste of the paste/paste GI composition disclosed herein is less than 20% by weight, based on the total weight of the composition.

Abstract: A nonwoven article includes a plurality of electrospun polycrystalline, aluminosilicate ceramic filaments that form a cohesive nonwoven mat. Each of the aluminosilicate ceramic filaments in the mat have an average diameter of about 200 nm to about 1000 nm as determined with electron microscopy, and the aluminosilicate ceramic filaments have an average crystalline mullite content of about 15 wt % to about 80 wt %.
