Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
81 words
A method for inhibiting dental plaque and promoting caries reduction in oral hygiene comprising dispersing an effective plaque inhibiting and caries-reducing amount of emulsan in water and contacting the aqueous dispersion of emulsan with dental surfaces susceptable to caries generally recognized to be caused by Streptococcus mutans as well as to growth of dental plaque through inhibition of attachment of S. mutans, as well as by desorbing S. mutans that have previously attached to dental surfaces in a mammalian oral cavity.
Claim 2
Independent Claim
81 words
A method for inhibiting dental plaque and promoting caries reduction in oral hygiene comprising dispersing an effective plaque inhibiting and caries-reducing amount of emulsan in water and contacting the aqueous dispersion of emulsan with dental surfaces susceptable to caries generally recognized to be caused by Streptococcus mutans as well as to growth of dental plaque through inhibition of attachment of S. mutans, as well as by desorbing S. mutans that have previously attached to dental surfaces in a mammalian oral cavity.
Claim 3
Dependent Claim
22 words
The method claimed in claim 1 wherein said emulsan is present in said aqueous dispersion in amount of about 0.05-10% by weight.
Claim 4
Dependent Claim
22 words
The method claimed in claim 2 wherein said emulsan is present in said aqueous dispersion in amount of about 0.1-3% by weight.
Claim 5
Dependent Claim
22 words
The method claimed in claim 3 wherein said emulsan is present in said aqueous dispersion in amount of about 0.25-1% by weight.
Claim 6
Dependent Claim
17 words
The method claimed in claim 1 wherein said aqueous dispersion is contacted with natural dental tooth surfaces.
Claim 7
Dependent Claim
11 words
The method claimed in claim 1 wherein said emulsan is apo-α-emulsan.
