Compositions having anti-dental caries function

Abstract

The present invention relates to dietary compositions and oral compositions having an anti-dental caries function. The present invention provides dietary compositions and oral compositions having an anti-dental caries functions which contain a buffering agent having a pH buffering action in the oral cavity.

       17 . An oral composition having an anti-dental caries function, wherein the composition comprises a buffering agent having a pH buffering action in the oral cavity, wherein the buffering agent is selected from the group consisting of: 
 phosphorylated oligosaccharides or sugar alcohol thereof, wherein the phosphorylated oligosaccharides are glucan consisting of 3 to 5 glucoses with α-1,4 linkages, one phosphate group being linked to the glucan, or glucan consisting of 2 to 8 glucoses with α-1,4 linkages, two phosphate groups being linked to the glucan;    chondroitin sulfate; and    chondroitin sulfate oligosaccharides.    
   
   
       18 .- 23 . (canceled)  
   
   
       24 . An oral composition having an anti-dental caries function, wherein the composition comprises a buffering agent having a pH buffering action in the oral cavity, a phosphorus-calcium compensating agent, a phosphorus preparation, and/or a calcium preparation, wherein the buffering agent is selected from the group consisting of: 
 phosphorylated oligosaccharides or sugar alcohol thereof, wherein the phosphorylated oligosaccharides are glucan consisting of 3 to 5 glucoses with α-1,4 linkages, one phosphate group being linked to the glucan, or glucan consisting of 2 to 8 glucoses with α-1,4 linkages, two phosphate groups being linked to the glucan;    chondroitin sulfate; and    chondroitin sulfate oligosaccharides.

       31 . A dietary composition according to  claim 3 , wherein the buffering agent is in the form of an alkaline metal salt, an alkaline earth metal salt, or an iron salt.  
   
   
       32 . A dietary composition according to  claim 31 , wherein the buffering agent is in the form of a sodium salt or a calcium salt.  
   
   
       33 . A dietary composition according to  claim 3 , further comprising an effective amount of fluorine or a fluorine containing substance for anti-dental caries.  
   
   
       34 . A dietary composition according to  claim 10 , wherein the buffering agent is in the form of an alkaline metal salt, an alkaline earth metal salt, or an iron salt.  
   
   
       35 . A dietary composition according to  claim 34 , wherein the buffering agent is in the form of a sodium salt or a calcium salt.
