The amorphous, or at least partially crystalline, glass-based joining material is suitable for high-temperature applications, particularly in fuel cells and/or sensors. In addition to SiO.sub.2 and B.sub.2O.sub.3 as glass formers, the joining material similarly contains BaO and CaO, whereby the amount of Al.sub.2O.sub.3 is limited. The joining material has a coefficient of linear thermal expansion of at least 7.0.Math.10.sup.6 K.sup.1 in a range of 20 C. to 300 C. The joining material can be used for joining ferritic high-grade steels and/or chromium-containing alloys and/or ceramics, such as stabilized zirconium oxide and/or aluminium oxide.

Metal-containing methacrylates incorporated into polymeric materials with antimicrobial capacity for biomedical applications, and more particularly for dental purposes, are provided. The incorporation of metal-containing methacrylates such as calcium methacrylate, tin methacrylate, copper methacrylate, silver methacrylate, in combination or alone, for potentializing antimicrobial effect of cements, in particular, to biomaterial compositions including metal containing methacrylates, such as calcium, tin, copper, silver, nickel, titanium and iron methacrylates, in the formulation of biomaterials for applications in human health provides advantages, particularly in dentistry, and allows for expressive antimicrobial activity to dental compositions, so as to be useful in dental prosthesis, operative dentistry, orthodontics, pediatric dentistry, implantodontics, and endodontics.

A method of attaching a dental article to the surface of a tooth includes providing the dental article and applying a coating including upconversion phosphors to a surface of the dental article. The method also includes applying a dental cement composition to the surface of the tooth and placing the dental article on the surface of the tooth such that the coating is adjacent the dental cement composition. The dental cement composition includes a polymerizable resin and a photoinitiator and is substantially free of upconversion phosphors. The method further includes irradiating the coating with a radiation source that emits radiation at a pre-determined fixed wavelength that causes the upconversion phosphors to emit radiation at an activation wavelength of the dental cement composition photoinitiator such that the dental cement composition cures in a region adjacent the coating and removing remaining uncured dental cement composition outside the dental article from the tooth.

The present invention relates to a kit and a probe for detecting porous dental hydroxyapatite that includes a protein capable of binding porous dental hydroxyapatite or a detector thereof. The invention also relates to a method for detecting a condition involving porous dental hydroxyapatite that includes detecting in or on a tooth or a sample of the tooth of a subject a protein bound to porous dental hydroxyapatite. The invention also relates to methods for detecting a hypomineralisation developmental dental defect or detecting intact and/or broken MIH enamel, and to a kit and method for removing a protein bound to porous dental hydroxyapatite.

A luminescent coating is disclosed that is used to dimensionally control the curing of a photocurable agent placed in close contact with the coating. The coating is applied at the interface of structures, such as brackets and prosthetics, or may be applied directly on a curable material for use in 3D printing, at the location where bonding material is needed to be cured. The luminescent coating irradiates from its structure the curing radiations necessary to photopolymerize the resin in response to a first radiation irradiated on its structure of a different wavelength.

Disclosed are methods for detecting demineralization of a surface of a tooth, comprising a) contacting the tooth of a subject with an orally acceptable, binding composition comprising a binding agent that binds to a demineralized surface of the tooth; b) removing unbound binding compound; c) contacting the tooth with an orally acceptable, detector composition comprising a probe compound that reacts with the binding agent to form a visually detectable reaction product; and d) detecting formation of the reaction product as an indication of the presence or extent of surface demineralization of the tooth. Systems, kits, and compositions for practicing the methods are also provided.

The present invention relates to oral care and dental implants. In particular, the present invention is a dental implant with a removable protective film that is used to prevent implant loss and remove unwanted residual cement.

The present invention relates to a kit of parts for detection and removal of carious dentin tissue comprising: (i) one or more compounds being a hydrazine derivative, and (ii) means for chemical treatment of carious dentin tissue. Further, the invention concerns a preparation containing an active, caries-dissolving two-component liquid in the form of a first active, caries-dissolving component and a second component which reduces the aggressiveness of the active component to mucous membranes, a viscosity increasing substance and one or more compounds being a hydrazine derivative. The hydrazine derivative labels carious dentin tissue selectively and substantially irreversibly in the presence of healthy dentin tissue, which is useful in the context of caries removal.

Provided herein are compositions for applying a reference marker pattern or grid to the surface of an object to be imaged three-dimensionally. These compositions can be quick drying for ease of use. Methods of use of the compositions are also provided as well as devices and kits for the application of the compositions.
