E.E. Newby, A. Butler, R. Labella. Summary: The correlation between organoleptic malodor and measured VSCs was not statistically significant but this may be improved by using a logarithmic transformation to normalize the distribution since the data set is positively skewed and by the inclusion of a population with higher baseline VSC levels or by taking logs of the VSC concentrations to allow for the positive skew in the data set. The GC has greater range than the malodor scale for high levels of VSCs but it is less able to discriminate between differences in low to moderate malodor .

A.J. Flanagan, R. McNab, E.E. Newby and J.R. Pratten.

Summary: CoQ0 is a potential new active for the control of oral malodor through multiple modes of action:

  • Protease inhibition reduces the substrates available for generation of VSC.
  • Antimicrobial activity eliminates bacteria that generate VSC (however, poor activity was observed against bacterial biofilms).
  • Reacts with VSC to neutralise odour.

G.C. Martin, E.E. Newby Summary: VSC production was altered dramatiaclly by changing cysteine levels and sparging gas from anaerobic to sterile lab air, probably through effects on VSC precursor levels and/or the microcosm species composition. Toward an anti-malodor screening tool.

G.R. Burnett, O. Elrashidy, R. Ignar, S.M. Wetterer. Summary: A liquid denture cleanser formulation reduced K. pneumoniae, V. atypica, A. viscosus, and S. sanguinis by >99.99% and F. nucleatum by 99.99% at 90 seconds. An effective alternative to effervescent tablets for the control of common oral bacteria.
