Abstract: [Object] To provide, for a composite resin (CR) having a wide range of applicable colors (shades) (wide-ranging color applicable CR), such as a CR having light diffusion properties and a CR that produces color by means of a structural color, a technology with which an excellent effect, specifically, an increased breadth (number) of applicable shades in comparison to an existing CR other than a wide-ranging color applicable CR, can be achieved.

Abstract: A demonstration method can include demonstrating a feature of a dental composite resin, the feature being that the dental composite resin exhibits high color tone applicability to teeth of a wide range of shades. The demonstration of the feature can include: displaying a restoration process of obtaining a plurality of restoration samples by filling with the dental composite resin a cavity or a defect part of each artificial tooth of a plurality of artificial teeth and curing the dental composite resin; and displaying the plurality of restoration samples obtained by the restoration process.
