[Methodological critical studies of taste using chemical stimuli].

Two methods of the chemical examination of taste were compared in view of its practicability. The "Three-Choice-Technique" is most profitable for the clinical use. It is carried out easily and quickly, and the results permit a sufficient and exact estimation of the taste sensitivity. The "Assorting-Technique" seems to be less useful. It provides lower thresholds, but the expense is higher. The Three-Choice-Technique, the special concentration sequences and the ascertained normal threshold for the four basic taste qualities enable a better registration of taste disturbances, at which side differences are of no consequence.
