Quick Reference

A theory, first described by M. Brännström in 1966, which suggested that dentine hypersensitivity is due to movement of fluid within the dentinal tubules in response to mechanical, osmotic, and evaporative stimuli. Cold stimuli cause an outward flow of fluid and hot stimuli cause an inward flow.
