Methods of forming antimicrobial resin compositions comprising silver nanoparticles are disclosed. Such methods generally comprise: combining a silver-containing material with a resin in situ in the presence of a silver-binding compound; and curing the resin. Antimicrobial polymeric resin compositions formed by said methods have a lighter color than control compositions and also display a slower release of silver ions over time.

To provide a dental composition wherein the acid buffering capacity can be attained and the acid resistance of the tooth substance can be improved while maintaining very high foul breath inhibition capacity. A dental composition including: ion sustained-release glass; and a carrier for supporting the ion sustained-release glass, wherein the ion sustained-release glass is fluoroaluminoborosilicate glass having a composition range of: 15% to 35% by mass SiO.sub.2; 15% to 30% by mass Al.sub.2O.sub.3; 5% to 20% by mass B.sub.2O.sub.3; 20% to 45% by mass SrO; 5% to 15% by mass F; and 0% to 10% by mass Na.sub.2O.

Base material arrangements having at least two layers can accommodate the addition of antifungal material (nanofiller), such as in denture base resin without significantly compromising the mechanical properties and/or translucency of the base material arrangements. Antifungal agents such as nanosilver and nanozirconia can be used to modify a surface layer of the material arrangements, such as the denture base, to overcome certain known shortcomings of the modified materials, e.g., typical acrylic resins containing nanosilver and nanozirconia.

A denture containing a henna powder or a henna extract, each of which comes from pulverized henna leaves and may include any of lawsone, tannic acid, and 2-methoxy-1,4-napthoquinone and a denture fabrication material. A denture containing at least one first antimicrobial ingredient selected from the group consisting of henna powder or a henna extract, lawsone, tannic acid, and 2-methoxy-1,4-napthoquinone, and a second antimicrobial ingredient, and optionally, a biocompatible gel and an odor neutralizer.

Aqueous solution of a transition and main group metal salt for use as conditioning agent in dental restoration therapy.

The invention relates to a kit of parts comprising a Base Paste (B) and a Catalyst Paste (C), Base Paste (B) comprising a cationically hardenable component, Catalyst Paste (C) comprising a starter component suitable to contribute to the hardening of the cationically hardenable compound, the composition obtained when combining the compositions of Base Paste (B) and Catalyst Paste (C) comprising in addition a porous water-adsorbing component and water, the porous water-adsorbing component being selected from molecular sieves, zeolites, silica gel and mixtures thereof, wherein either the porous water-adsorbing component is present in Base Paste (B) and the water is present in Catalyst Paste (C), or the water-adsorbing component is present in Catalyst Paste (C) and the water is present in Base Paste (B). The invention also relates to a dental retraction composition obtainable by mixing Base Paste (B) and Catalyst Paste (C) and to a process of taking a dental impression and/or conducting a dental retraction using the kit of parts.

A gutta-percha composition for filling a tooth root canal includes a temperature indicating component, such that the user has a visual indication that the material is ready for placement in the prepared canal. The material may include a thermochromatic dye, bismuth oxide or the like, in an otherwise conventional obturation material.

A dentition strengthening delivery system having separate phosphate and calcium salts derived from separate source in a semisolid comestible matrix. The ratio of phosphate to calcium is at least 1:1, and the phosphate concentration is between about 10 ppm to about 10,000 ppm.
