The present invention provides a dentinal tubule occlusion material excellent in terms of initial degree of dentinal tubule occlusion, resistance of dentinal tubule occlusion to acids, handling properties, and storage stability. The present invention relates to an one-pack type dentinal tubule occlusion material comprising fluorapatite particles (A) having an average particle diameter of 0.6 to 10 μm, inorganic particles (B) having an average particle diameter of 0.6 to 10 μm and reactive with water to form apatite, and a non-aqueous dispersant (C).

A dental crown composed of fiber mesh sheets of fiberglass, aramid, carbon or quartz fibers embedded within dentally acceptable resin. The combination of both materials synergistically add unsurpassed strength and enhanced cosmetic value to the dental crown for a much lower price due to the cheaper costs of the material and manufacturing process.

Filmogenic compositions are described for topical anaesthetic bioadhesives (TABs) comprising a) a xanthan biopolymer matrix selected from Xanthomonas species and pathovars, including Xanthomonas campestris pathovars campestris and maninhotis, and Xanthomonas arboricola pathovar pruni, a producer of pruni xanthan, wherein the matrix is made of pure or combined xanthan varieties in any proportion, said matrix comprising between 1% and 95% by weight of the total weight of the composition, and additives or excipients; b) at least one anaesthetic, in a proportion of 0.1% to 50% by weight of the total weight of the composition. The topical anaesthetic bioadhesives (TABs) are also described, and they may be applied to the gingival mucosa and/or alveolar mucosa on the buccal (1) or lingual/buccal (2) surfaces with extensions and anatomical contours for crowns of the upper and lower dental arches.

Presented herein is an optical filter system for visible light, which has a first average transmittance T.sub.1 between a limit wavelength λ.sub.G and a wavelength of 700 nm and a second average transmittance T.sub.2 between a wavelength of 380 nm and the limit wavelength λ.sub.G. In this case: 410 nm<λ.sub.G<520 nm and 0.05

[00001]$<\frac{T_1}{T_2}<0.60.$

The present invention relates to methods and compositions for treating pulmonary infection. In particular, the present invention provides nanoemulsion compositions and methods of using the same to treat bacteria associated with biofilms (e.g., found in pulmonary infections). Compositions and methods of the present invention find use in, among other things, clinical (e.g. therapeutic and preventative medicine), industrial, and research applications.

The present invention relates to a hydrogel formulation in which the solid phase is composed of a continuous net work of siloxane bonds and one or more calcium phosphate phases doped with one or more metal dopants.

A composition for tissue degradation and removal and disinfection is provided for dental and medical applications. It can function as a single intra-canal irrigant that eradicates microorganisms as it facilitates the debridement of a root canal system. It contains one or more hydoxides, a thioglycolate compound, sodium hypochlorite, sodium chloride, sodium chlorate, oxygen, and water, such as lime water and purified water, The thioglycolate compound is capable of degrading a cell by disrupting disulfide bonds in its proteins. The sodium hypochlorite enhances its function. The composition may also incorporate mineral oil, urea, cetearyl alcohol, D&C yellow No. 8, chromium hydroxide, theobroma cocoa seed butter, iron oxides, fragrances, lanolin, and/or ceteareth-20. It is effective against Enterococcus faecalis.

The present invention relates in a first aspect to an adhesion material for use in an individual containing encapsulated phase-change material. In particular, the adhesion material is for cosmetical or medicinal use in the body of an individual. The adhesion material contains encapsulated phase-change material having preferably a phase transition temperature above 40° C., like above 55° C. The adhesion material is particularly useful for adhering elements, like dental restorations, e.g. crowns or bridge, or brackets on elements in the body of an individual, like teeth or implants. That is, the adhesion material is particularly useful for adhering material in dental applications. In another aspect, a method is provided allowing removing a bracket, a crown or bridge, from implants, abutments or teeth. Furthermore, dental implant restoration systems and kits for permanent fixation of implants allowing improved removal thereof are provided.

The invention consists of a rapidly crosslinkable, two-component silicone elastomer together with a specially designed tray that serves as a form for the silicone resin and forms an integral portion of a dental appliance.
