Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
45 words
An oral composition comprising an oral vehicle, a tartar and stain removing effective amount of a strontium EDTA complex substantially free of strontium ions from sources other than the strontium EDTA complex and an effective anti-caries amount of a water soluble inorganic ionic fluoride salt.
Claim 2
Dependent Claim
45 words
