Abstract: A system for providing an oral care agent includes a first layer containing the oral care agent and a second layer. The first layer can be applied directly to teeth. The second layer can subsequently be applied onto the first layer to inhibit leakage of the oral care agent outwards into the mouth.

Abstract: The present invention relates to patient interfaces optically indicating a user that a member of the patient interface needs to be replaced due to wear. In particular, the present invention relates to a member for patient interface which includes at least one functional material having a predefined functionality and at least one indicator wherein the concentration of the at least one indicator in the member correlates with the predefined functionality of the at least one functional material.

Abstract: Disclosed are oral healthcare methods for the delivery of amorphous calcium phosphate (ACP) to an oral cavity. Further disclosed is a composition comprising amorphous calcium phosphate for use in the occlusion of dental tubules and/or the deposition of remineralising agents on dental enamel.

Abstract: Disclosed is a hydrophilic silicone composition comprising an oral care substance. The composition is based on polysiloxanes having a high water-uptake capability. An aqueous solution or dispersion of the oral care substance can be soaked into the polysiloxane, whereby the resulting composition shows favorable release characteristics. The use of hydrophilically modified polysiloxanes, possibly in conjunction with unmodified hydrophobic polysiloxanes, allows for the convenient production of desired shapes, advantageously based on a dental imprint. The hydrophilic modification of the polysiloxane is particularly by including a hydrophilic vinyl monomer, particularly an alpha-olefinic soap, into the composition prior to curing.

Abstract: Disclosed is a system for providing an oral care active formulation that delivers amorphous calcium phosphate (ACP) to the teeth of a subject. The system comprises a component that provides calcium ions and a component that provides phosphate ions. The invention allows to obtain increased ACP concentrations as a result of the inclusion, in either or both of the components, of one or more basic amino acids. The invention also allows providing ACP via the administration of a two-component solvent-based varnish.

Abstract: Patient interface (50) optically indicating a user that a member (22) of the patient interface (50) needs to be replaced due to wear. In particular, it relates to a member (22) for patient interface (50) which comprises at least one functional material (32, 34) having a predefined functionality and at least one indicator (28, 30) wherein the concentration of said at least one indicator (28, 30) in said member (22) correlates with the predefined functionality of said at least one functional material (32, 34).

The second layer can subsequently be applied onto the first layer to inhibit leakage of the oral care agent outwards into the mouth.

Abstract: A delivery device (12) includes a source (16) of pressurized fluid, a nozzle (24, 16) which defines an outlet (22), a pathway (20) which fluidly connects the source of pressurized fluid with the nozzle outlet (22) for delivery of a spray of fluid from the nozzle outlet, and a receptacle (32), which receives a dose of particles (28). The receptacle is positioned in the pathway such that the dose of the particles is carried by the pressurized fluid and through the nozzle outlet, the particles including a tooth whitening agent.
