Herbal Composite Preparation and Investigating its Efficiency to Inhibit Biofilm Formation and Virulence Factors of and - Formulation of Mouthwash Using a Herbal Composite and Evaluating its Anti-microbial Activity.

Herbal composite preparation was studied with the aim of inhibiting the virulence factors of two dental pathogens: and . A novel herbal composite was developed using the herbal extracts of and . During the study, the following observations were noted. The minimal inhibitory concentration of and composites (WBc) was obtained for the test concentration of 20 μg/ml (16 ± 0.57 mm and 15 ± 0.75 mm of inhibitory zones against and , respectively). Biofilm inhibition assay results revealed about 0.51 ± 1.25 mg/ml and 0.53 ± 0.57 mg/ml of minimal biofilm eradication concentration (MBEC) against and , respectively. The effect of WBc on lactic acid production showed that 200 μg/ml and 400 μg/ml concentrates reduced up to 80% and 70% in and , respectively. Formulated herbal mouthwash showed good stability under all three different test conditions (5°C, 25°C, and 40°C) as the color, odor, phase separation, and homogeneity were not changed for the period of 3 months. The anti-bacterial activity of formulated mouthwash (30 μg/ml) exhibited maximum inhibitory zones of about 18 ± 0.75 mm and 19 ± 1.05 mm against the respective test bacteria - and . Amplification of and genes showed 246 bp and 294 bp fragments of and 238 bp and 280 bp fragments of during agarose electrophoretic analysis. The docking report revealed -5.84 Kcal/Mol binding energy and found three hydrogen bonding between the quercetin and target protein, of . The target protein, of , and quercetin had -6.72 Kcal/Mol binding energy and found four hydrogen bonds between them. The developed composite could be optimized in future to develop a novel and biocompatible herbal mouthwash for the prevention of different dental caries and gingival inflammation associated with dental biofilm formation.
