Aim:
To compare the antimicrobial efficacy of an herbal and 0.2% chlorhexidine gluconate mouthrinse against Streptococcus mutans, Staphylococcus aureus, and Enterococcus faecalis.
Materials And Methods:
The antimicrobial effectiveness (zone of inhibition) of a herbal mouthrinse and 0.2% chlorhexidine mouthrinse were determined by agar well-diffusion method.
Results:
At 50% concentration, the experimental mouthrinse inhibits the growth of Streptococcus mutans, Staphylococcus aureus, and Enterococcus faecalis.
Conclusion:
Against the three strains, chlorhexidine mouthrinse (0.2%) performs better in terms of antimicrobial effectiveness.
