RESUMEN

Introduction: Over the past century, several antibiotics have been discovered and used to treat various microbial diseases. However, over the past few decades, with the emergence of anti-microbial resistant strains of microbiomes, it has become increasingly necessary to discover and develop alternative anti-microbial agents. Herbal formulations have shown promising results in the past decade. However, many herbal formulations remain unexplored. The present study aims to explore the anti-microbial properties of a newly prepared Vanilla planifolia extract. Methodology: Vanilla planifolia leaves were collected, shade-dried, and then powdered. The powdered leaves of Vanilla planifolia (100 gm) were extracted by the cold percolation method with 300 ml ethanol at room temperature for 72 hours. The extracts were then tested for its constituent anti-microbial activity by the agar well method and disk diffusion method against different commonly found oral micro-biomes. The zones of inhibition were noted and measured, and the results were derived. Statistical analysis was performed using the Student t-test (P <_ 0.001). Based on the statistical analysis, conclusions were drawn. Results: The ethanolic extracts of Vanilla planifolia on the agar plates showed considerable anti-microbial activity in both the test methods against Staphylococcus aureus, Streptococcus mutans, and Enterococcus. However, no effect was found against Candida albicans. There was no significant difference in the results obtained by the two test methods (P >_ 0.001). Conclusions: This experimental study presents a medicinal plant, an orchid Vanilla planifolia, which demonstrates the presence of essential anti-microbial agents in it, making it a potent, potential dental biomaterial with a positive and benefitting effect on the oral micro-environment.
