Hydrodynamic theory (dentistry) explained
Web7 nov. 2011 · The hypersensitivity of dentin is based on Brännström’s hydrodynamic theory that stimuli create a pressure change or disturbance within the fluid that fills the dentinal tubules. The movement of the fluid in the open tubules is then transmitted to the A-delta nerve fibres. Heat, cold, air, and pressure can cause this rapid movement of fluid ...
