Theories of dentin sensitivity
WebbHydrodynamic theory : According to Brännström s hydrodynamic theory,8when an appropriate stimulus is applied to the outer dentin surface, there is a displacement of the contents of the dentinal tubules, that gives rise to a mechanical stimulation of the pain at the pulpodentinal border. Webb1. Hydrodynamic theory by Brannstrom (J Endod 1986) - Rapid fluid movement in dentinal tubules following stimuli activates sensory nerves. 2. Conduction theory by Frank (Arch …
