The Taste Strips are a validated examination procedure to investigate the taste ability. When testing the whole-mouth taste ability, the Taste Strips are applied by putting them on the tongue and closing the mouth. If there is interest in the gustatory sensitivity of certain tongue areas, the mouth stays open and the strip will only be in contact with this area until the patient can give an answer. The 20’s Set consists of 4 containers in highest concentrations of sweet, sour, salty and bitter. Every container has 25 Taste Strips, i.e. 100 Taste Strips in total. An instruction for use and evaluation material is not included. This item is drop shipped for best use and longevity. May take 3 weeks for delivery.
