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.

1 . A method for promoting the remineralization of teeth in early dental caries comprising the administration of a dietary composition, said composition comprising a buffering agent having a pH buffering action in the oral cavity, wherein the buffering agent is a phosphorylated oligosaccharide or sugar alcohol thereof.  
   
   
       2 . A method according to  claim 1 , wherein the buffering agent is in the form of an alkaline metal salt, an alkaline earth metal salt, or an iron salt.  
   
   
       3 . A method according to  claim 2 , wherein the buffering agent is in the form of a sodium salt or a calcium salt.  
   
   
       4 . A method according to  claim 1 , wherein the composition further comprises an effective amount of fluorine or a fluorine containing substance for anti-dental caries.  
   
   
       5 . A method for promoting the remineralization of teeth in early dental caries comprising the administration of a dietary composition, said composition comprising 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 a phosphorylated oligosaccharide or sugar alcohol thereof.  
   
   
       6 . A method according to  claim 5 , wherein the buffering agent is a phosphorylated oligosaccharide 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.  
   
   
       7 . A method according to  claim 5 , wherein the buffering agent is in the form of an alkaline metal salt, an alkaline earth metal salt, or an iron salt.  
   
   
       8 . A method according to  claim 7 , wherein the buffering agent is in the form of a sodium salt or a calcium salt.  
   
   
       9 . A method according to  claim 5 , wherein the composition further comprises an effective amount of fluorine or a fluorine containing substance for anti-dental caries.  
   
   
       10 . A method for promoting the remineralization of teeth in early dental caries comprising the administration of an oral composition, said composition comprising a buffering agent having a pH buffering action in the oral cavity, wherein the buffering agent is a phosphorylated oligosaccharide or sugar alcohol thereof.  
   
   
       11 . A method according to  claim 10 , wherein the buffering agent is a phosphorylated oligosaccharide 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.  
   
   
       12 . A method according to  claim 10 , wherein the buffering agent is in the form of an alkaline metal salt, an alkaline earth metal salt, a zinc salt or an iron salt.  
   
   
       13 . A method according to  claim 12 , wherein the buffering agent is in the form of a sodium salt, a calcium salt, or a zinc salt.  
   
   
       14 . A method according to  claim 10 , wherein the composition further comprises an effective amount of fluorine or a fluorine containing substance for anti-dental caries.  
   
   
       15 . A method for promoting the remineralization of teeth in early dental caries comprising the administration of an oral composition, said composition comprising 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 a phosphorylated oligosaccharide or sugar alcohol thereof.  
   
   
       16 . A method according to  claim 15 , wherein the buffering agent is a phosphorylated oligosaccharide 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.  
   
   
       17 . A method according to  claim 15 , wherein the buffering agent is in the form of an alkaline metal salt, an alkaline earth metal salt, a zinc salt, or an iron salt.  
   
   
       18 . A method according to  claim 17 , wherein the buffering agent is in the form of a sodium salt, a calcium salt, or a zinc salt.  
   
   
       19 . A method according to  claim 15 , wherein the composition further comprises an effective amount of fluorine or a fluorine containing substance for anti-dental caries.
