Abstract

Introduction: Dental caries is an infectious disease and various microorganisms have a pivotal role in its onset and development. Medications used to reduce microbes are usually accompanied with side effects. Therefore, it seems necessary to search for antimicrobial agents with less side effects. In this study, we aimed to evaluate the antimicrobial effects of aqueous and alcoholic extracts of saffron on oral pathogenic microbes. Materials &amp; Methods: In total, six 9-year-old male students were selected from a primary school. Samples of dental plaque, saliva, and depth of tooth decay were obtained from the participants to evaluate Streptococcus mutans, Lactobacillus, and Candida albicans and were sent to the laboratory afterwards. After assessing the samples via broth dilution method and incubation, six samples of Lactobacillus, eight samples of Candida albicans, and six samples of Streptococcus mutans were evaluated due to difficulty in turbidity detection. Afterwards, overnight cultures were prepared and evaluated for minimal bactericidal concentration (MBC) determination. In the next stage, penicillin and nystatin positive culture tests were used to compare the effects of microbes. In this study, one-way ANOVA was used to compare all the study groups, while pairwise comparison was performed using Tukey test. Results: Our findings were indicative of inhibitory effects of aqueous and alcoholic extracts of saffron on all three microbes. However, they were less effective compared to standard antibiotics (e.g., penicillin). A significant difference was observed between the effect of aqueous and alcoholic extracts of saffron and penicillin on the Streptococcus mutans (P<0.001). Similarly, a significant difference was found between the effects of saffron extracts and penicillin on the Lactobacillus (P<0.0001). Moreover, a significance difference was observed between extracts of saffron and nystatin on Candida albicans (P<0.001). According to the results, alcoholic extract of saffron was more successful in eliminating Candida albicans and Streptococcus Mutans, compared to aqueous extract of saffron (P<0.001). Conclusion: According to the results, while saffron had bacteriostatic effects on Streptococcus mutans and Lactobacillus, it had antifungal activities against Candida albicans. Therefore, saffron could be recommended as a mouthwash due to its herbal origin, cost-effectiveness, and fewer side effects.
