Mouth Funk?

Overview

Objectives/Goals My problem was which mouth wash will kill streptococcus salivarious. My hypothesis was that scope mouthwash would kill the most streptococcus salivarious. Scope has an active ingredient called cetylpyridinium chloride anti-plaque agent with bactericidal activity. This is why I think scope will kill the most streptococcus salivarious. Methods/Materials I inoculated streptococcus salivarious on to sterile petri dish with nutrient agar. Dipped sterile blank disk into one of the six mouthwashes I am testing. Put blank sterile disk containing mouthwash on petri dish (two sterile disks per dish). Then I incubated dishes for 24 hours at 34 degrees celsius. Results The best working mouthwash was mountain breeze reducing a total average of .25 centimeters of streptococcus salivarious. Then came scope reducing .24 centimeters, rite aid reducing .15 centimeters, equate reducing .09 centimeters, and last cogate phosflur and listerine reducing .05 centimeters average. Conclusions/Discussion Out of the six mouthwashes that were tested the largest zone of inhibition was mountain breeze, second was scope, third was rite aid, fourth was equate, listerine and colgate phosflur were tied for fifth. My hypothesis was wrong, mountain breeze has a larger zone of inhibition because of more effective ingerdients. Mountain breeze has two active ingredients one is peroxide and the other is cetylpyridinium chloride which are both antiplaque agents with bacteriacidal. This is why mountain breeze was the most effevtive mouthwash by killin streptococcus salvarious.
