Theories of dentin sensitivity
Webb15 maj 2024 · The dentin is the part of the tooth structure directly underneath the enamel. Dentin hypersensitivity is also referred to as dentin sensitivity. This can cause significant deterioration of the ... Webb4 jan. 2016 · Hypersensitivity typically occurs in the cervical area where the dentin is exposed because the protective enamel/cement was not formed or is worn out or etched away (Figs. 4 and 5). The odontoblasts and/or pulp cells respond by forming intratubular deposits or eventually tertiary dentin is laid down.

WebbTheories. A variety of theories have been suggested to help explain the mechanism involved in the etiology of dentinal hypersensitivity.11 The transducer theory, the … Webb• Dentinal hypersensitivity is characterised by short sharp pain arising from exposed dentine in response to stimuli typically thermal, evaporative ,tactile, osmotic or chemical and which cannot be ascribed to any other form of defect or disease. (Holland Et al 1997) • In 2003,Canadian Advisory hypersensitivity recommend the use of
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. WebbSelf-reported dentin sensitivity is higher among individuals in their third and fourth decades of life ranging from 45 – 57.2%. [1, 2]Sensitivity is characterized by short, sharp pains …
WebbThe dentine innervation theory is based on the premise that dentine is innervated and that the stimulation of the nerve endings within dentinal tubules causes hypersensitivity. [43] …
