Antibacterial effect of Stryphnodendron adstringens (Mart) Coville (Fabaceae) extract on dental caries

Abstract

It is common knowledge the current trend of developing and testing products accrued from natural plants. On that premise, Stryphnodendron adstringens (Mart) Coville is highlighted and was the aim for evaluating its antibacterial effect on dental caries. A crude dried methanolic extract was prepared and applied from 50 to 500 mg/mL to determine the Minimum Inhibitory Concentration (MIC) on seven distinguished bacterial cultures. Results revealed by 0.01% resazurin demonstrated Stryphnodendron adstringens (Mart) Coville extract exerted antibacterial effect on all tested bacterial strains, with MIC > 250 mg/mL for Lactobacillus casei, Streptococcus mitis and Streptococcus salivarius and MIC > 400 mg/mL for Enterococcus faecalis, Streptococcus mutans, Streptococcus sanguinis and Streptococcus sobrinus. In view of outcomes, the tested crude vegetal extract presents antibacterial potential for application in dental caries.
