Claim 1
Independent Claim
129 words
A METHOD OF KILLING ESCHERICHIA COLI STREPTOCOCCUS MUTANS STAPHYLOCOCCUS AUREUS OR CANDIDA ALBICANS PRESENT IN INFLAMED TISSUES OF THE MOUTH WHICH COMPRISES CONTACTING SAID BACTERIA OR FUNGUS WITH AN EFFECTIVE NON-TOXIC AMOUNT OF A FRESHLY PREPARED COMPOSITION CONSISTING OF AGED SOLUTION (A) WHICH COMPRISES THE REACTION PRODUCT OF 0.5 TO 8 ML OF A 1 TO 20 WEIGHT PERCENT AQUEOUS CHROMIC ACID SOLUTION AND 30 ML OF A 1 TO 20 WEIGHT PERCENT AQUEOUS HYDROGEN PEROXIDE SOLUTION SAID PRODUCT EXHIBITING A PH OF ABOUT 4 CONTAINS BOTH CR+3 AND CR+6 IONS AND HAS BEEN AGED AT LEAST 24 HOURS, AND SOLUTION (B) WHICH CONSISTS OF A 1 TO 20 WEIGHT PERCENT AQUEOUS HYDROGEN PEROXIDE SOLUTION IN THE PROPORTION OF BETWEEN 1:10 AND 10:1 OF SOLUTION (A) TO SOLUTION (B).
Claim 2
Independent Claim
129 words
A METHOD OF KILLING ESCHERICHIA COLI STREPTOCOCCUS MUTANS STAPHYLOCOCCUS AUREUS OR CANDIDA ALBICANS PRESENT IN INFLAMED TISSUES OF THE MOUTH WHICH COMPRISES CONTACTING SAID BACTERIA OR FUNGUS WITH AN EFFECTIVE NON-TOXIC AMOUNT OF A FRESHLY PREPARED COMPOSITION CONSISTING OF AGED SOLUTION (A) WHICH COMPRISES THE REACTION PRODUCT OF 0.5 TO 8 ML OF A 1 TO 20 WEIGHT PERCENT AQUEOUS CHROMIC ACID SOLUTION AND 30 ML OF A 1 TO 20 WEIGHT PERCENT AQUEOUS HYDROGEN PEROXIDE SOLUTION SAID PRODUCT EXHIBITING A PH OF ABOUT 4 CONTAINS BOTH CR+3 AND CR+6 IONS AND HAS BEEN AGED AT LEAST 24 HOURS, AND SOLUTION (B) WHICH CONSISTS OF A 1 TO 20 WEIGHT PERCENT AQUEOUS HYDROGEN PEROXIDE SOLUTION IN THE PROPORTION OF BETWEEN 1:10 AND 10:1 OF SOLUTION (A) TO SOLUTION (B).
Claim 3
Dependent Claim
22 words
The method of claim 1 wherein the proportions by volume of said aged solution (a) and said hydrogen peroxide (b) are 1:1.
Claim 4
Dependent Claim
46 words
The method of claim 1 wherein said composition consists of the reaction product of 1 to 2 cc of 8 percent chromic acid solution and 30 cc of 3 percent hydrogen-peroxide to form solution (A) and solution (B) is 30 cc of 3 percent hydrogen peroxide.
Claim 5
Independent Claim
121 words
The method of diminishing dental plaqUe which comprises applying to the mouth of the subject having dental plaque an effective non-toxic amount of a freshly prepared composition consisting of aged solution (A), which comprises the reaction product of 0.5 to 8 ml of a 1 to 20 weight percent aqueous chromic acid solution and 30 ml of a 1 to 20 weight percent aqueous hydrogen peroxide solution, said product exhibiting a pH of about 4, contains both Cr 3 and Cr 6 ions, and has been aged at least 24 hours; and solution (B) which consits of a 1 to 20 weight percent aqueous hydrogen peroxide solution; in the proportion of between 1:10 and 10:1 of solution (A) to solution (B).
Claim 6
Independent Claim
121 words
The method of diminishing dental plaqUe which comprises applying to the mouth of the subject having dental plaque an effective non-toxic amount of a freshly prepared composition consisting of aged solution (A), which comprises the reaction product of 0.5 to 8 ml of a 1 to 20 weight percent aqueous chromic acid solution and 30 ml of a 1 to 20 weight percent aqueous hydrogen peroxide solution, said product exhibiting a pH of about 4, contains both Cr 3 and Cr 6 ions, and has been aged at least 24 hours; and solution (B) which consits of a 1 to 20 weight percent aqueous hydrogen peroxide solution; in the proportion of between 1:10 and 10:1 of solution (A) to solution (B).
Claim 7
Dependent Claim
