...Pinar Altinci; Roda Seseogullari-Dirihan; Gulsen Can; David Pashley; Arzu Tezvergil-Mutluay The enzymatic degradation of dentin organic matrix occurs via both the action of matrix metalloproteinases (MMPs) and cysteine cathepsins (CCs). Zinc can prevent collagen hydrolysis by MMPs. However, its...

...Nasrine R. Mohammed; Richard J.M. Lynch; Paul Anderson Metal ions including zinc have the ability to influence enamel demineralisation. However, there is a paucity of data regarding reductions in demineralisation effected by zinc ions (Zn 2+ ) in the literature. Therefore the aim was to measure...

...R. Osorio; E. Osorio; I. Cabello; M. Toledano The aim of this study was to ascertain whether zinc may improve the repair ability of demineralized dentin. Dentin disks were demineralized by phosphoric acid during 15 s and immersed in artificial saliva, remineralizing solution, a zinc chloride...

...M.N. Hegde; N.D. Hegde; A. Ashok; S. Shetty This study evaluated the superoxide dismutase (SOD) activity, copper and zinc levels in saliva of caries-active and caries-free individuals. Eighty healthy adults were divided according to WHO criteria: caries-free (DMFT = 0) and caries-active (DMFT...

...M. Toledano; M. Yamauti; E. Osorio; R. Osorio Background: Dentine matrix metalloproteinases (MMPs) play an important role in the dentine caries process. Aims: To determine if MMP-mediated collagen degradation of acid-demineralized dentine may be inhibited by zinc or zinc chelators. Methods: Human...

...F. Lippert The present mechanistic in vitro study aimed to investigate dose-response effects of zinc and fluoride on caries lesion remineralization and subsequent protection from demineralization. Artificial caries lesions were created using a methylcellulose acid gel system. Lesions were...

...R.J.M. Lynch; D. Churchley; A. Butler; S. Kearns; G.V. Thomas; T.C. Badrock; L. Cooper; S.M. Higham The aim was to study the effects of zinc (Zn) and fluoride (F) on remineralisation at plaque fluid concentrations. Artificial carious lesions were created in 2 acid-gel demineralising systems...

...A.A. Scheie; E.I.F. Pearce Mouthrinses containing zinc ions inhibit plaque acidogenicity, but the effect is transient. Zinc-containing apatite or zinc phosphate precipitated within dental plaque might serve as a reservoir for zinc ions, thus providing prolonged inhibition of acid formation. Zinc...

...H.P. Davey; G. Embery; D. Cummins As zinc has been included in several oral health products as an anticalculus and antiplaque agent, the interaction of zinc with a synthetic phosphate was investigated. The synthetic calcium phosphate used in this study was β-tricalcium phosphate, or whitlockite...

...R.K. Rose; R.P Shellis; A.R. Lee The cation-bridged fluoride binding model proposed previously was tested by measuring fluoride binding to Streptococcus mutans R9 in the presence and absence of calcium, magnesium or zinc ions. The dissociation constant for fluoride binding to washed cells was 8.4...

...R.K. Rose Calcium bound by oral bacteria may have important effects on plaque cohesion and mineral dynamics. Equilibrium dialysis was used here to study the effect of magnesium and zinc competition on calcium-binding by Streptococcus sanguis 7863. Experiments were carried out using 45 Ca in 0.1–5.0...

...G.S. Ingram; C.P. Horay; W.J. Stead As some currently available toothpastes contain zinc compounds, the reaction of zinc with dental mineral and its effect on crystal growth rates were studied using three synthetic calcium-deficient hydroxyapatites (HAP) as being representative of dental mineral...

... and etiologically important plaque bacteria. Because the efficacy of sanguinarine is believed to be enhanced by zinc, isobolograms were assessed to determine their mode(s) of interaction. Hydrogen ion concentration influenced the inhibitory activity of both sanguinarine and zinc. For sanguinarine, at the optimum pH...

After 48 h, the concentration of solubilized zinc from aqueous solutions of 5.0 m M zinc citrate was 12.0 m M versus 14.4 mMin the presence of 34.7 m M SLS. The plaque-inhibiting properties of aqueous solutions of 12.0 m M Zn 2+ from zinc citrate...

A single rinse with 0.05% (w/v) sanguinarine chloride without Zn did not affect the in vivo acidogenicity of established plaque beyond...

...E.J. Izaguirre-Fernández; A.D. Eisenberg; M.E.J. Curzon Effects of zinc and/or fluoride on growth, glycolysis and survival of Streptococcus mutans GS-5 were examined in vitro. Zinc inhibited growth and glycolysis, and enhanced the antimetabolic activity of fluoride. Zinc alone had little effect...
