Claims31
An aesthetic dental sealant comprising a hardenable resin, a hardener, and a photobleachable dye, wherein the hardener comprises a sensitizing compound different from the photobleachable dye, and wherein the dental sealant has an initial color prior to exposure to actinic radiation and a final color that is different from the initial color subsequent to the dental sealant being exposed to actinic radiation.
A method of using an aesthetic dental sealant comprising:
- providing a color-changing, dental sealant having an initial color, wherein the dental sealant comprises a hardenable resin, a hardener and a photobleachable dye, with the hardener comprising a sensitizing compound different from the photobleachable dye;
- applying the dental sealant onto a tooth surface;
- hardening the dental sealant;
- and
- exposing the dental sealant to actinic radiation to change the color of the dental sealant from the initial color to a final color.
A kit comprising:
- an aesthetic dental sealant comprising a hardenable resin, a hardener, and a photobleachable dye, wherein the hardener comprises a sensitizing compound different from the photobleachable dye, and wherein the dental sealant has an initial color prior to exposure to actinic radiation and a final color that is different from the initial color subsequent to the dental sealant being exposed to actinic radiation;
- and
- instructions for using the dental sealant.
