An example article may include a dental surface, a hydrophobic coating on the dental surface, and a restorative layer on the hydrophobic coating. An example technique may include applying, on a dental surface, a hydrophobic coating comprising an amphiphilic agent. The hydrophobic coating may provide a water contact angle of greater than or equal to about 50° on the dental surface. The example technique may include applying a restorative layer to the hydrophobic coating. An example kit may include a dental restorative composition and a hydrophobic coating composition. The hydrophobic coating composition may include an amphiphilic agent. The hydrophobic coating composition may be configured to provide a water contact angle of greater than or equal to about 50° on a dental surface.

This invention designs and builds multiple layers (two layers or more) of various dental devices, specifically denture base or denture, where printed multiple layered denture base with teeth cavities to receive artificial denture tooth materials to form final dental devices, such as partial and full dentures. It can also print denture teeth. This invention also designs and prints multiple layers (two layers or more) of denture base with artificial denture teeth to form final dental devices, such as partial and full dentures. A method for manufacturing a layered denture is provided. The invention provides a multiple layered denture base materials for printing a denture base. The invention also provides a multiple layered denture tooth materials for printing artificial denture teeth. Highly shape adjustable or shape memory polymer layer(s) may be used in these multiple layered denture base forms. Different layer of material has different mechanical and physical properties to meet different need, which provide added benefits to the patients, dental professional and dental laboratory.

There is provided an oral biofilm inhibitor having an exceptional inhibitory effect on oral biofilm formation. It is an oral biofilm inhibitor comprising a curable composition containing an antimicrobial agent, wherein a compressive strength of a cured product formed by curing the composition is 150 MPa or less, and a content of the antimicrobial agent is 0.001 to 3% by weight. An oral biofilm inhibitor thus obtained is used for inhibiting biofilm formation in an oral cavity by applying a curable composition containing an antimicrobial agent to a dental defect site for allowing the composition to cure at the dental defect site, and then disintegrating the cured composition.

The present invention provides a method that enables production of a surface-treated colored inorganic particle with which the desired color tone can be consistently reproduced as intended with no variation occurring in the color tone of the compositions produced with the particle, within each production and over multiple production runs. The invention relates to a method for producing a surface-treated colored inorganic particle, comprising spray drying a mixture of a dispersion [I] and a solution [II], wherein the dispersion [I] is a dispersion of inorganic particles having an average particle diameter of 0.005 to 5 μm dispersed in a solvent with a pigment, and the solution [II] is a solution of a surface treatment agent hydrolyzed in the presence of a hydrolysis aid.
