It is characterized by short, sharp afferent nerve ending in the dentin tubule, resulting in pain.10 pain arising from exposed dentin in response to stimuli, It is, therefore, understandable that the pain caused by this typically thermal, evaporative, tactile, osmotic or chemical, change is transient – once the stimulus is removed or and which cannot be ascribed to any other dental defect or dissipates, the pressure within the tubule returns to normal disease.1,2 The diagnosis of dentin hypersensitivity can be and the pain subsides. very challenging for the dental professional. The cause of the Sensitivity triggers and behavioral considerations pain can vary and the patient’s description of the discomfort may be insufficient to make a definitive diagnosis.
