Opis

Dentin hypersensitivity (DH) is a common dental condition characterized by sharp, transient pain arising from exposed dentin in response to thermal, tactile, osmotic, or chemical stimuli. It occurs when the protective enamel or cementum is lost, exposing dentinal tubules. According to the hydrodynamic theory, movement of fluid within these open tubules stimulates nerve endings in the pulp, causing pain. DH is most often seen in cervical areas due to gingival recession, abrasion, erosion, or periodontal treatment. Management includes desensitizing agents (e.g., potassium nitrate, strontium, fluoride varnishes), tubule-occluding materials (resins, bioactive glass), and laser therapy, aiming to block nerve response or seal tubules.
