Claims18
A method of treating a silver stain on a tooth comprising:
- applying a sodium hypochlorite solution to a treated area of the tooth comprising the silver stain, wherein the silver stain has a first area and a first shade;
- maintaining the sodium hypochlorite solution in contact with the treated area for a first time period to produce a treated tooth and a treated silver stain having a second area and a second shade;
- wherein one of the second area is less than the first area and the second shade is lighter than the first shade.
A kit for the treatment of a silver stained tooth comprising:
- a single-use container holding a volume of a sodium hypochlorite solution;
- and
- a single use applicator for the sodium hypochlorite solution.
A method for removing silver stain from a tooth comprising;
- applying a sodium hypochlorite solution to a stained area of a tooth treated with silver diamine fluoride;
- wherein the stained area comprises a visible silver oxide material on a surface of the tooth;
- wherein the applying the sodium hypochlorite solution is effective to produce radical oxygen and chlorine,
- wherein the radical oxygen is effective to hydrolyze proteins that are attached to the silver stain and the chlorine is effective to precipitate white silver chloride, and
- wherein the applying the sodium hypochlorite solution is effective to remove a substantial amount of the visible silver oxide material from the surface of the tooth.
