Abstract: Dental caries is an infectious disease wherein tooth enamel is progressively dissolved by acid producing bacteria in the mouth. Preventative strategies, most notably in the form of fluoride products, are the most common means of treating caries, however, fluoride-free products are also available. Often alternative treatments are plant-based and less strictly regulated than their more conventional counterparts. Determining whether two such alternative ingredients truly exhibit antibacterial action against oral bacteria was the objective of this research. Polyphenolic compounds from two plant sources, green tea and perilla seed oil, were tested to determine antibacterial properties against Streptococcus salivarius and Lactobacillus acidophilus. Although both showed strong antibacterial activity against S. salivarius, inhibitive effects against L. acidophilus were more ambiguous. Green tea showed stronger activity than perilla seed oil, possibly due to a lower concentration of polyphenols in the latter. Determination of specific polyphenolic constituents in these commercial sources is suggested before true inhibitive concentration can be determined. Influence on other oral bacteria as well as bioavailability of these products should also be researched before the beneficial nature of their affects can be fully claimed.
