Abstract

Abstract Numerous chemical stimuli have been used to click pain from exposed dentin. Most of the effective chemicals share a common denominator; they arc all very hypertonic. Dentin surfaces covered with a smear layer are much less responsive to hypertonic solutions than dentin devoid of a smear layer. These observations support the hydrodynamic theory of dentin sensitivity. The most important variables influencing the efficacy of chemical stimuli include: ionic composition, presence or absence of calcium, sodium or potassium, pH and osmolality (tonicity). Although hypertonic solutions of sucrose or CaCl2 can be useful qualitative stimuli, the theoretical objections to using them for quantitative evaluation of dentinal sensitivity seem to far out‐weight their advantages.
