A dental bite block device includes a front wall, a flat lateral sidewall, and a concave lateral sidewall that define a longitudinal channel that extends through the device. The lateral sidewalls are connected by a crossbar, and the channel can be filled with polyvinyl siloxane (PVS) dental impression putty. When the device is positioned in the patient's mouth, the flat lateral sidewall faces the right inner check of the patient, the patient's tongue rests against the concave lateral sidewall, and the patient's upper and lower teeth rest open on the front wall. Once the PVS putty sets, it forms a solid half cylinder-shaped member that includes impressions of a plurality of the patient's upper and lower teeth, which assist to maintain the device in place. The front wall and concave sidewall further include an opening that defines a clip for a saliva ejector.

The invention relates to the application of a composition containing recombinant amelogenin and propylene glycol alginate (PGA) on to cut dentin tubules followed by installation of a definitive restorative in a single visit.

To provide a dental glass ionomer cement composition which exhibits high mechanical properties. The dental glass ionomer cement composition of the present disclosure comprises

(a) non-crosslinked polyalkenoic acid,

(b) water,

(c) crosslinked polyalkenoic acid: 0.01 to 10 wt. %, and

(d) acid-reactive glass powder.

[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.

[Solving Means] For example, in a demonstration instrument, a plurality of samples is prepared, a single wide-ranging color applicable CR has been used to restore a cavity in artificial teeth each having a different shade, the cavity being formed at a predetermined position of the artificial teeth, and the plurality of samples is disposed side by side and fixed on a display surface of a display plate, thereby making it possible to compare/contrast conditions of restored portions of the samples to each other and the color tone applicability thereof to those of a teeth to be restored.

The invention relates to a multi-layer, preferably co-extruded, plastic film with improved modulus properties, which is suitable, in particular, for producing three-dimensionally shaped articles.

A method can include applying a clear or mostly clear dental coating on one or more teeth for preserving the structure and/or appearance of the one or more teeth. The method can include bleaching the one or more teeth before applying the clear or mostly clear dental coating.
