Toothbrush

Abstract

Tooth decay is prevented by suppressing activity of intraoral fungi by providing on a toothbrush a product obtained by pulverizing shells having crystalline structural body of calcite type structure of calcium carbonate. A handle ( 2 ) or bristles ( 3 ) of the toothbrush ( 1 ) are formed of synthetic resin mixed with the product obtained by pulverizing shells having crystalline structural body of calcite type structure of calcium carbonate.

1 . A toothbrush comprising at least one of bristles of a synthetic resin with which a product obtained by pulverizing shells having crystalline structural body of calcite type structure of calcium carbonate is mixed, or a handle of a synthetic resin with which a product obtained by pulverizing shells having crystalline structural body of calcite type structure of calcium carbonate is mixed.  
   
   
       2 . A toothbrush comprising at least one of bristles coated with a coating material containing a product obtained by pulverizing shells having crystalline structural body of calcite type structure of calcium carbonate, or a handle coated with a coating material containing a product obtained by pulverizing shells having crystalline structural body of calcite type structure of calcium carbonate.  
   
   
       3 . The toothbrush according to  claim 1  or  2 , wherein the product is a mixture of a calcium carbonate powder comprising porous granules which is a shell powder having crystalline structural body of calcite type structure of calcium carbonate and a calcium oxide powder prepared by calcining the calcium carbonate powder, or an aqueous solution of the mixture.  
   
   
       1 . A toothbrush comprising at least one of bristles of a synthetic resin with which a product obtained by pulverizing shells having crystalline structural body of calcite type structure of calcium carbonate is mixed, or a handle of a synthetic resin with which a product obtained by pulverizing shells having crystalline structural body of calcite type structure of calcium carbonate is mixed.  
   
   
       2 . A toothbrush comprising at least one of bristles coated with a coating material containing a product obtained by pulverizing shells having crystalline structural body of calcite type structure of calcium carbonate, or a handle coated with a coating material containing a product obtained by pulverizing shells having crystalline structural body of calcite type structure of calcium carbonate.  
   
   
       3 . The toothbrush according to  claim 1 , wherein the product is a mixture of a calcium carbonate powder comprising porous granules which is a shell powder having crystalline structural body of calcite type structure of calcium carbonate and a calcium oxide powder prepared by calcining the calcium carbonate powder, or an aqueous solution of the mixture.  
   
   
       4 . The toothbrush according to  claim 2 , wherein the product is a mixture of a calcium carbonate powder comprising porous granules which is a shell powder having crystalline structural body of calcite type structure of calcium carbonate and a calcium oxide powder prepared by calcining the calcium carbonate powder, or an aqueous solution of the mixture.
