Syzygium aromaticum essential oil prevents halitosis caused by oral bacteria Streptococcus sanguinis

Abstract

Halitosis is caused by oral bacteria including Streptococcus sanguinis in mouth producing volatile sulphur compounds (VSCs), such as hydrogen sulfide, ethyl mercaptan, and methyl mercaptan which have pungent odor. Bacteria producing sulphur compounds produce oral biofilms as the accumulation of caries promotion. Caries is caused by the acid produced by oral bacteria that lead to tooth demineralization in low pH condition. Clove bud (Syzygium aromaticum), known as endogenous spice in Indonesia, has been traditionally used for centuries for treatment of periondal diseases. In this study, we extracted essential oil from Syzygium aromaticum (SAEO), identifed for its major essential oils by pyrolysis gas chromatograpy mass spectrometry (py-GC/MS), determined its antihalitosis efficacy on preventing and eradicating S. sanguinis oral biofilms, inhibiting VSCs and acid production in vitro. Chromatogram profile showed that SAEO contained major eugenol (22.10%) and aceteugenol (13.31%). For antibiofilm effect toward oral bacteria S. sanguinis, SAEO at 40 and 60 μg/mL effectively prevented biofilm formation up to 60% and removed the existed biofilms up to 50%. SAEO at 60 μg/mL also demonstrated a significant inhibition on VSCs production (up to 58%) and acid produced by S. sanguinis by increasing the terminal pH from 5.66 to 6.30. These data suggest that SAEO could be applied for a promising candidate for developing oral care functional products for management of halitosis.

“…Streptococcus sanguinis (S. sanguinis) and Streptococcus mitis (S. mitis) bacteria can be one of the causes of this emerging issue. They produce volatile sulphur compounds (VSCs) such as hydrogen sulfide, ethyl mercaptan, and methyl mercaptan, which have a pungent odour (Yanti, Juniardi, and Lay 2019). The action of these bacteria can be suppressed with carnosic acid.…”
