Conventional dental cements lack certain properties such as the facilitation of optimal re-mineral-ization. The novel bioactive glass-ionomer dental and bone cement formulations disclosed herein induces mineralization at the in vivo interface and exhibits superior handling properties (shorter setting time) and mechanical properties (improved bond strength to dentin and flexural strength). The present invention presents the first bioactive glass-ionomer dental cement with mineralization power, exhibiting improved bond strength to tooth structure, sharp setting time and superior me-chanical strength.

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.

Fibers, for example fiberglass fibers, are added to dental stone powders to provide for reinforced dental stones. Dental stones are made by combining dry components, including binder and fiber glass, adding water to the resulting mixture and setting the mixture in a dental mold. The dental stones are reinforced by the fibers, and allow for reduced breaking or chipping during handling.

A hardenable (e.g. dental) compositions is described comprising an encapsulated material. The encapsulated material comprises a basic core material and an inorganic shell material having certain viscosity criteria. Also described are dispensing devices and kits are described comprising a hardenable (e.g. dental) composition comprising a liquid material and an encapsulated material wherein the encapsulated material comprises a basic core material and an inorganic shell material comprising a metal oxide surrounding the core. The dispensing devices and kits can facilitate the methods of applying the hardenable composition. The hardenable or hardened (e.g. cured) composition can provide various technical effects such as a delayed release of a basic core material, a delayed increase in basicity, promoting remineralization of a tooth or bone structure, and increasing the average alkaline phosphatase (ALP) activity of pulp cells. In some embodiments, the composition is a dental (e.g. sealant) composition for application to a tooth structure.

The present invention provides a dental curable composition suitable as a flowable composite resin. The dental curable composition, when in the form of a cured product, has excellent mechanical strength, polishability, and gloss retention, and, when in the form of a paste, has consistency appropriate for discharge through a needle attached to the tip of a syringe and exhibits good formability and handling properties after discharge through the needle. The present invention is a dental curable composition including: a polymerizable monomer (A); irregularly-shaped inorganic particles (B) having an average particle diameter of 0.1 to 0.3 m and surface-treated with a silane coupling agent having a particular structure; and inorganic ultrafine particles (C) having an average particle diameter of 5 to 50 nm and surface-treated with a silane coupling agent having a particular structure, the dental curable composition containing 92.5 to 98 weight % of the irregularly-shaped inorganic particles (B) and 2 to 7.5 weight % of the inorganic ultrafine particles (C) relative to the amount of total inorganic particles and having a consistency of 25 to 55.
