Automated electrogustometry: a new paradigm for the estimation of taste detection thresholds.

Electrogustometery, first introduced in the 1950s for the clinical assessment of taste function, has returned to favour in recent years. This is due, in part, to the credence given to the procedure by an increased understanding of the mechanisms of taste transduction. The reliability and validity of electrogustometric assessments of taste function should increase with the use of automated testing. An automated computer-controlled testing paradigm was used to obtain threshold estimates simultaneously from the left and right sides of the tongue in 97 volunteers aged between 17 and 63 years. A small but statistically significant advantage was found for thresholds from the right side of the tongue (P<0.01). The range of thresholds, and of interside differences obtained with this procedure, are reported, and practical issues related to testing are discussed.
