Monofluorophosphate Blocks Internal Polysaccharide Synthesis in Streptococcus mutans.

Streptococcus mutans is the leading cause of dental caries worldwide by accumulating a glycogen-like internal polysaccharide (IPS) that contributes to cariogenicity when sugars are in excess. Sodium monofluorophosphate (MFP) is an active anticariogenic compound in toothpastes. Herein, we show that MFP inhibits (with an I0.

Remineralization potential of an anticaries/antigingivitis mouthrinse.

Purpose: To assess the ability of a new formulation (Listerine with 0.022% NaF) to remineralize initially decalcified bovine enamel compared to a positive control, clinically established 0.022% NaF rinse.

Ab initio study of AmCl(+): f-f spectroscopy and chemical binding.

A valence full configuration interaction study with a polarized double-zeta quality basis set has been carried out for the lowest 49 electronic states of AmCl(+). The calculations use a pseudopotential treatment for the core electrons and incorporate a one-electron spin-orbit interaction operator. Electrons in the valence s, p, d, and f subshells were included in the active space.

Effect of fluoride/essential oils-containing mouthrinse on the microhardness of demineralized bovine enamel.

Purpose: To assess the ability of a fluoride mouthrinse containing a fixed combination of essential oils (thymol, menthol, eucalyptol, and methyl salicylate) to inhibit demineralization as compared with that of a clinically established NaF rinse.

Methods: Inhibition in sound bovine enamel to demineralization was assessed utilizing a cyclic T/R/D (treatment/remineralization/demineralization) in vitro model where Knoop microhardness was monitored over 6, 12, and 18 T/R/D cycles.

Results: Both fluoride-containing mouthrinses resulted in statistically significant increase in microhardness when compared to the non-fluoride control mouthrinse, possibly demonstrating and validating the in vitro model's ability to parallel the clinically established benefit of a 0.

The inhibition of mercury absorption by dietary ethanol in humans: cross-sectional and case-control studies.

Background: Since the inhibition of mercury absorption by ethanol was serendipitously discovered in 1965,(1) a limited number of small number studies with both animal and human subjects have reported results consistent with this finding.

Aims: To investigate this phenomenon in a large scale human study with low level Hg exposed dentists.

Methods: Data were collected for a sample of 1171 dentists, and both cross sectional and case-control methods were utilised to examine the data.
