Antibacterial Effectiveness of Chitosan Solution on Streptococcus Mutans

Dental caries is a localized destruction on teeth by organic acid produced carbohydrate fermentation of cariogenic bacteria. Streptococcus mutans Gram-positive bacterium, facultative anaerobe species often found in human oral cavity and significant contributor to dental caries. Chitosan the collective name group partially or fully deacetylated chitin. Because its unique biological properties, including biodegradability nontoxicity, lot applications have been for chitosan, own combined with other polymers. has wide spectrum activity high killing rate against Gram positive Gram-negative bacteria, while having low toxicity mammal cell. In this research Kirby-Bauer test done using 1%, 1.5%, 2% chitosan solution as treatment aquades control group. Average each calculated significancy determined statistical calculation. The resulting data analyzed Kruskal-Wallis Post-hoc Tukey HSD shown there be difference between groups. biggest zone inhibition seen higher antibacterial effectiveness than 1% 1.5% solution.
