Comparative Evaluation of the Antimicrobial Efficacy of Elettaria cardamomum (0.5%) Mouthwash, Camellia sinensis (0.5%) Mouthwash, and 0.12% Chlorhexidine Gluconate Mouthwash against Streptococcus mutans: An In Vitro Study.

Aim: The in vitro study aimed to evaluate and compare the antimicrobial efficacy of Elettaria cardamomum (0.5%) mouthwash, Camellia sinensis (0.5%) mouthwash, and 0.12% chlorhexidine gluconate mouthwash against Streptococcus mutans.
Materials and Methods: A total of 60 samples of the five mouthwash preparations were prepared to check for their antimicrobial efficacy. The zone of inhibition (ZOI) against S. mutans was measured as a diameter in mm, and the minimum inhibitory concentration (MIC) of mouthwash preparations was measured as μg/mL. All the groups were compared statistically using the Mann-Whitney U test and the Kruskal-Wallis test.
Results: The highest ZOI was observed in group V chlorhexidine gluconate [mean: 20.8, standard deviation (SD): 0.58], followed by group III C. sinensis (alcohol-free) (mean: 15.5, SD: 0.67), group IV C. sinensis (alcohol-based) (mean: 14.08, SD: 0.66), and group II E. cardamomum (alcohol-based) (mean: 13.2, SD: 0.45). The least ZOI was observed in group I E. cardamomum (alcohol-free) (mean: 10.7, SD: 0.45). This difference was statistically significant ( p < 0.01). The MIC was similar in all the groups ( p = 0.13).
Conclusion: Chlorhexidine gluconate 0.12% mouthwash showed the best antimicrobial action; however, C. sinensis mouthwash showed potential against S. mutans. E. cardamomum mouthwash exhibited limited antimicrobial activity.
