Provided are methods and compositions relating to a dental composition more specifically to prepare the damaged dentin of the tooth for animals and pets such as canine, feline and members of the taxonomic family Equidae prior to repair. The dental compositions include a bioactive glass and a non-aqueous solvent comprising an alcohol, anti-inflammatory and anti-pain reliever.

An antibacterial fiber that exhibits predetermined antibacterial properties even when washed repeatedly for 50 or more times, and a method for producing an antibacterial fiber are provided.

Disclosed are an antibacterial fiber containing a thermoplastic resin and antibacterial glass particles, and a method for producing the antibacterial fiber, the antibacterial fiber having cracks extending along the length direction of the antibacterial fiber on the surface of the antibacterial fiber, each of the cracks being in a state of having at least one of the antibacterial glass particles sandwiched therein.

A sediment mixture configured to be used as an abrasive agent is disclosed herein. The sediment mixture includes a plurality of component particles comprising particle shapes selected from the group consisting of: (i) an approximately spherical shape, (ii) an approximately tear-drop shape, (iii) an approximately cylindrical shape, (iv) a truncated ellipsoidal shape, (v) a dog-bone or hour-glass shape, and (vi) combinations thereof.

The present invention provides a material composition and a process of producing translucent ZrO.sub.2—SiO.sub.2 nanocrystalline glass ceramic (NCGC) with ultra-high flexural strength. The method comprises the following step: (1) prepare homogenous ZrO2-SiO2 nano-sized powder with high purity via a sol-gel method; (2) pressure assisted sintering of ZrO2-SiO2 nano-sized sol-gel powder to obtain translucent ZrO2-SiO2 NCGC. The invention also includes materials manufactured using the method.

The invention relates to a radiopaque glass having a refractive index n.sub.d of 1.480 to 1.561, this glass, apart from impurities at most, being free from SrO and PbO. The glass is based on the SiO.sub.2, Al.sub.2O.sub.3 and B.sub.2O.sub.3 system. The radiopacity can be adjusted using Cs.sub.2O in particular in combination with BaO and/or SnO.sub.2 optionally in conjunction with fluorine. The glass may be used in particular as dental glass or as optical glass.
