Abstract

An apparatus (40) for assessing treatment effectiveness of tooth sensitivity with an oral care product comprising a tooth shaped member (50) comprises an outer layer (60) simulating an enamel, wherein the outer layer (60) at least partially covers an exterior surface of an inner layer (70) simulating a pulp, and a liquid sensor (80) contained either between the outer layer (60) and inner layer (70), or within the inner layer (70); and a plurality of holes (90), simulating open dentin tubules, configured through the outer layer (60) to the inner layer (70), and in fluid communication with the liquid sensor (80); wherein the liquid sensor (80) is configured to sense liquid passing through at least one of the plurality of holes (90) as simulating the treatment effectiveness of tooth sensitivity of the oral care product.
