Journal Title: International Journal of Health Sciences and Research - Year 2017, Vol 7, Issue 4
Abstract
Dental caries is a major public health problem. Streptococcus mutans and Lactobacillus acidophilus are the main organisms responsible for the initiation and progression of caries. Various antimicrobials have been used against these caries causing organisms but they have many side effects. Hence there is a need for an alternative which is effective as well as economical. Ocimum sanctum L. has been used in traditional medicine since ancient times for its diverse healing properties. However there is a paucity of literature regarding its antimicrobial activity against oral microorganisms. Objective: To determine the antimicrobial effect of Ocimum sanctum L. against caries causing microorganisms Streptococcus mutans and Lactobacillus acidophilus. Material and Methods: Ethanolic Ocimum sanctum L. extract was prepared and Minimum Inhibitory Concentration (MIC) of the extract was determined against Streptococcus mutans and Lactobacillus acidophilus by serial broth dilution method. Results:The MIC of ethanolic extract of Ocimum sanctum L. against Streptococcus mutans and Lactobacillus acidophilus was 2.5% (25mg/ml) and 10% (100 mg/ml) respectively. Conclusion: The ethanolic extract of Ocimum sanctum L. showed antimicrobial activity against Streptococcus mutans and Lactobacillus acidophilus.
