Hexane, ethyl acetate, and methanol extracts of of Persea Americana leave were tested against the dental caries causing bacteria Streptococcus mutans from caries infected patients. Bioactivity of the concentrations of 0%, 5%, 10%, 15%, and 20% of all the extracts showed an increasing (P ?0.05) activity. The concentrations of 20% in all solvents’ plant extracts showed the highest bioactivity. The bioactivity strength against Streptococcus mutans of the three solvents’ plant extracts showed no significant differences (P ? 0.05) among each other and had a comparable antibacterial activity to that of chlorhexidine.
Key words; Persea Americana, Antimicrobial activity, Streptococcus mutans, chlorhexidine
