The effects of toothpaste on taste were studied electrophysiologically wite the 4 basic gustatory stimuli (0.1M NaCl. 1.0M sucrose, 0.05M tataric acid and 0.005M quinine-HCl) in rats. Electrophysiological records of the 4 basic taste responses were obtained from the chorda tympani nerve, before and after treatment of the tongue with toothpaste.
The summated chorda tympani nerve responses to NaCl, tartaric acid and quinine-HCl were inhibited by toothpaste applied to the tongue surface.
Through the inhibitory effects of toothpaste on quinine-HCl were especially strong and lasting, these effects were reversible. There were no significant effects on responses to sucrose.
