Inhibition halos were measured in mm. The DW negative control was excluded from the statistical analyses because it did not present antimicrobial efficacy against S. mutans. HET = hydroalcoholic extract of tocosh, CHx = chlorhexidine, and DW = distilled water. Shapiro–Wilk test. ANOVA test. ^a,b,dBonferroni post hoc test: post hoc test of the antibacterial effectiveness of HET against S. mutans was statistically significant in all groups (). ^cHowever, no differences were observed between HET 50% and chlorhexidine 0.12% ().
