ABSTRACT
Herbal composite preparation was studied with the aim of inhibiting the virulence factors of two dental pathogens Prevotella intermedia and Porphyromonas gingivalis. A novel herbal composite was developed using the herbal extracts of Wrightia tinctoria and Bauhinia variegata. During the study, the following observations were noted. The minimal inhibitory concentration of Wrightia tinctoria and Bauhinia variegata 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 Prevotella intermedia and Porphyromonas gingivalis, 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 Prevotella intermedia and Porphyromonas gingivalis, 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 Prevotella intermedia and Porphyromonas gingivalis, 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 - Prevotella intermedia and Porphyromonas gingivalis. Amplification of mfa1 and clpB genes showed 246 bp and 294 bp fragments of P. gingivalis and 238 bp and 280 bp fragments of P. intermedia 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, mfa1 of Porphyromonas gingivalis. The target protein, clpB of Prevotella intermedia, 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.
