In-vitro study on the effect of cinnamaldehyde, eugenol and polydatin on the growth of Streptococcus mutans and the formation of dental plaque biofilms.

Laboratory testing found that a combination of cinnamaldehyde, eugenol and polydatin together worked synergistically to inhibit *Streptococcus mutans* growth and biofilm formation while reducing toxicity to human gingival cells, suggesting potential for developing natural anticaries treatments.
