Claims Analysis
Total Claims: 31
Claim 1
Independent Claim
67 words
A process for inhibiting dental caries comprising contacting the surface of a tooth with an oral and dental hygiene preparation containing a C 2 -C 4 -alkoxylated trihydric to hexahydric C 3 -C 12 -aliphatic polyol wherein at least one hydroxyl moiety is esterified with phosphoric acid, or a physiologically compatible water soluble salt thereof in a non-toxic amount sufficient to inhibit dental caries in said tooth.
Claim 2
Dependent Claim
67 words
A process for inhibiting dental caries comprising contacting the surface of a tooth with an oral and dental hygiene preparation containing a C 2 -C 4 -alkoxylated trihydric to hexahydric C 3 -C 12 -aliphatic polyol wherein at least one hydroxyl moiety is esterified with phosphoric acid, or a physiologically compatible water soluble salt thereof in a non-toxic amount sufficient to inhibit dental caries in said tooth.
