Methods and kits for removing calculus from a tooth, wherein the method can include applying a component A to the tooth, wherein component A comprises a hydrogen peroxide or a precursor thereto; applying a component B to the tooth, wherein component B comprises a non-enzymatic, hydrogen peroxide decomposition catalyst for generating oxygen gas; wherein components A and B are applied simultaneously or sequentially to the tooth, thereby generating oxygen gas to soften and/or loosen at least part of the calculus on the tooth; and removing at least a part of the calculus from the tooth.

Methods and kits for removing calculus using a non-enzymatic, hydrogen peroxide decomposition catalyst

An aqueous oral care solution, a kit that includes such solution, a method of making such solution, a method of using such solution (e.g., a method of providing fluoride to a patient's tooth surface), and a tooth surface having a coating derived from the aqueous oral care solution, wherein the oral care solution includes: silver cations; thiocyanatc anions provided by a thiocyanatc source comprising Ca(SCN)2; fluoride anions; and water; wherein the molar ratio of silver to thiocyanatc ions is up to 0.40:1, and water is up to 57 wt-%, based on the total weight of the solution.

Aqueous oral care solutions, methods, kits, and tooth surfaces having a coating derived from the oral care solution

Methods and kits for removing calculus from a tooth. The method includes applying a component A comprising hydrogen peroxide or a precursor thereto to the tooth; applying a component B comprising a catalase to the tooth, thereby generating oxygen; and removing at least a part of the calculus from the tooth; wherein the component A is applied before or after the component B is applied.

The invention relates to plastics which are self-disinfecting. The invention relates in particular to polyether or silicone based dental plastics and impression materials in which a biocidal material is incorporated. The dental impression material ace. to the invention comprises at least a polymerizable base paste BP and a non-aqueous catalyst paste CP, wherein the base paste BP comprises about 0.001 to about 10% by weight of a water-stable anti-microbial agent. Preferred anti-microbial agents are selected from the group consisting of Hexitidin, Cetypyridininumcloride (CPC), Chlorhexidine and its derivates (CHX) and Triclosan.

Anti-microbial dental impression material

The invention relates to a water-soluble composition comprising a water miscible liquid and water-soluble particles, the water-soluble composition being essentially free of water. The composition can be used e.g. as dental composition, cleaning agent, polishing agent, tongue surface cleaning agent or peeling agent.

A nozzle head () for a powder jet device (), for use in applying dental material, comprises a first fluid flow path () for delivering a powder/fluid mixture to a first discharge nozzle (A). A second fluid flow path () is provided for delivering a liquid to a second discharge nozzle (A) located adjacent the first discharge nozzle (A), so that the materials discharged by the first and second discharge nozzles combine at a desired location to form a dental composition. A nozzle-clearing member () is located inside the nozzle head and is movable to remove powder material from the first discharge nozzle when the flow of powder/fluid mixture to the nozzle ceases.

Powder jet device for applying dental material

The invention relates to a dental composition comprising a hardenable powder to be used in a process for retraction of dental tissue. The invention also relates to a kit of parts comprising the dental composition comprising a hardenable powder, a hardening agent, optionally a handpiece of a powder jet device, optionally a powder jet device, and optionally retraction caps. In a further aspect, the invention relates to a method for retracting dental tissue comprising the steps of applying a dental composition comprising a hardenable powder with a powder jet device into the sulcus between soft and hard dental tissue, applying a composition comprising a hardening agent either before or after the previous step, leaving the dental composition in the sulcus for a time sufficient to effect retraction of the soft dental tissue and removing the dental composition from the sulcus.
