Correlation of Gustatory Tests

Abstract

Three kinds of gustatory tests (electrogustometry, filter paper disk method, drop technique) were performed in 80 patients.
1) The drop technique was most sensitive in detecting gustatory disorders.
2) When electrogustometry was performed along with the drop technique, the positive rate was not significantly different from the results obtained when the three tests were used, therefore, for clinical use, electrogustometry and the drop technique are advocated for early detection as well as long term follow up of gustatory disorders.
3) The threshold of electrogustometry correlated well with the average thresholds of the four basic tastes.
4) A positive correlation was found among the thresholds of the four basic tastes.
