Abstract

Introduction: Dental caries is largely caused by microflora. Medicinal plants have gained increased attention due to the negative consequences of pharmaceutical medications and their effect on oral cavity like stain of teeth, dryness of mouth etc., the current study evaluates the impact of Karpuravalli aqueous extract on the growth of Streptococcus mutans, Staphylococcus aureus, and Candida albicans.

Materials and methods: In this in-vitro experimental study, suspensions of standard strains of S. mutans and S. aureus were inoculated on using Müller-Hinton agar using a sterile swab and Candida albicans were inoculated on slant of potato dextrose agar. A disc containing the control groups, including 0.2% chlorhexidine and DMSO, was also placed on the plates. The plates were placed in a jar for 24 hours at 37°C and then the inhibition zone diameter around each disc was measured.

Results:The aqueous extract of Karpuravalli is able to inhibit the growth of Staphylococcus aureus, Streptococcus mutans and Candida albicans. The plant extract has the equal potential to inhibit the candidal growth to chlorhexidine. Likewise, it had nearby inhibitory effect for S. mutans and S. aureus to chlorhexidine.

Conclusion: Plectranthus amboinicus extract has antimicrobial properties against Staphylococcus aureus, Streptococcus mutans and Candida albicans. Thus, it implies that a component of the plant extract has anti-cariogenic and anti-plaque properties.
