The correlation between organoleptic mouth-odor ratings and levels of volatile sulfur compounds.
An organoleptic rating (OR) technique and gas-liquid chromatography were employed to study the relationship between oral-malodor ratings and the corresponding concentrations of oral volatile sulfur compounds (VSC) in a total of 102 subjects in two separate studies. Both studies demonstrated a statistically significant positive correlation between the intensity of perceived oral malodor and the concentration of VSC (H2S + CH3SH) emitted by individual subjects.
