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. WebbHuman dentine is sensitive to mechanical and thermal stimuli and to any procedure which tends to remove water from its surface and its sensitivity to mechanical stimuli appears to be due to displacement of tubule contents rather than to distortion of the dentine matrix. 54 PDF View 1 excerpt, cites background
