Abstract

The present study was done to evaluate the in vivo cariostatic efficacy of aqueous and ethanolic extracts of liquorice to ascertain whether it could be developed into a caries-preventive regimen basically targeted for use in the pediatric population. Thirty schoolchildren of 6-12-year-old were selected for the study. Powder of Glycyrrhiza glabra is used to prepare the gel with various concentration of aqueous and ethanolic liquorice gel. The preweighed dose was delivered through the vials. The drug concentrations were based on their respective minimum bactericidal concentration (MBC) values against Streptococcus mutans, which were calculated earlier. And it is divided into three groups, i.e., group I: aqueous liquorice extract 1.75 g/10 mL saline, group II: ethanolic liquorice extract 350 mg/10 mL, and group III: hexidine (0.2% chlorhexidine, CHX). For statistical analysis, Tukey's post hoc with one-way analysis of variance (ANOVA) and t test were applied. It was found that hexigel has a potential antibacterial activity against S. mutans, with minimum inhibitory concentration (MIC) of 3.14 ± 2.02. Ethanolic liquorice shows MIC of 2.15 ± 0.91 and aqueous liquorice shows MIC of 1.30 ± 1.08. Tukey's post hoc test showed statistica...Continue Reading
