Two mechanisms of oral malodor inhibition by zinc ions

Abstract: ObjectivesThe aim of this study was to reveal the mechanisms by which zinc ions inhibit oral malodor.Material and MethodsThe direct binding of zinc ions to gaseous hydrogen sulfide (H2S) was assessed in comparison with other metal ions. Nine metal chlorides and six metal acetates were examined. To understand the strength of H2S volatilization inhibition, the minimum concentration needed to inhibit H2S volatilization was determined using serial dilution methods. Subsequently, the inhibitory activities of zinc i… Show more

“…Previous reports showed that the inhibitory effect of Zn 2+ on halitosis involves two different mechanisms, direct binding with gaseous hydrogen sulfide and inhibitory growth of volatile sulfur compounds 20 . It has also been reported that Zn 2+ inhibits the growth of oral bacteria 19 .…”

“…In our study, IgY was able to significantly reduce VSCs by inhibiting the growth of bacteria. Zinc ions have two mechanisms of malodor inhibition by binding with H 2 S and antimicrobial activity [27]. According to the reports, F. nucleatum produces VSC, which is related with Cdl (Fn1220) and Lcd (Fn0625) [28].…”

“…Recently Suzuki et al [147] confirmed that zinc ions might be useful in inhibiting oral malodor caused by excess of gaseous hydrogen sulfide. Two mechanisms were responsible for the effect of these ions-direct binding of H 2 S by Zn 2+ and suppression of growth of oral bacteria.…”
