Abstract
A dental bleach system and method whereby fumed silica is used as a base for forming a paste with a solution of hydrogen peroxide, the paste acting as a nonreactive carrier to control the delivery of the hydrogen peroxide solution to the dental surface. The fumed silica is provided as a predetermined quantity in a mixing chamber while the hydrogen peroxide solution is provided as a premeasured volume in an ampule. Both items are made available to the dental care professional in a single patient use kit.
Claims12
A dental bleach system for use by a dental professional to bleach teeth comprising:
- a kit comprising a tray having at least a first compartment and a second compartment, said first compartment containing a sealed container of hydrogen peroxide solution having a concentration of hydrogen peroxide substantially within the range of 30% to 35% by volume, said second compartment comprising a mixing chamber and containing a body of fumed silica, said hydrogen peroxide solution and said body of fumed silica comprising a single patient application;
- mixing means for mixing said hydrogen peroxide solution with said fumed silica in said mixing chamber to produce a paste of said hydrogen peroxide solution and said fumed silica;
- application means for applying said paste to the teeth for a predetermined period of time for bleaching the teeth;
- and
- a cover releasably sealed to said tray, said cover being removable to expose said first compartment before said second compartment to allow the dental professional to retrieve said sealed container of hydrogen peroxide solution prior to exposing said body of fumed silica.
A dental bleach system for use by a dental professional for bleaching teeth comprising:
- a tray, said tray comprising a first compartment, a second compartment, and a cover removably mounted to said tray to enclose said first compartment and said second compartment, removal of said cover exposing said first compartment before said second compartment;
- an ampule containing a quantity of hydrogen peroxide in said first compartment, said quantity of hydrogen peroxide having a concentration of hydrogen peroxide substantially within the range of 30% to 35% by volume;
- a body of fumed silica in said second compartment;
- mixing means for mixing said hydrogen peroxide into said fumed silica in said second compartment to form a paste comprising said fumed silica and said quantity of hydrogen peroxide, said paste being prepared immediately prior to being applied to the teeth and
- application means for applying said paste to the teeth.
A method for bleaching teeth by a dental professional comprising:
- obtaining a body of fumed silica;
- preparing a solution of hydrogen peroxide, said hydrogen peroxide being present in said solution at a concentration substantially within the range of 30% to 35% by volume;
- sealingly enclosing said solution of hydrogen peroxide in a single patient use ampule;
- selecting a tray with a mixing chamber and packaging said ampule in said tray adjacent said mixing chamber;
- releasably sealing said tray with a cover, said cover being selectively removable to expose said hydrogen peroxide prior to exposing said fumed silica;
- forming a bleaching paste by mixing said solution of hydrogen peroxide with said fumed silica in said mixing chamber;
- and
- applying said bleaching paste to the teeth.
