Dentin hypersensitivity (abbreviated to DH,〔 or DHS, and also termed sensitive dentin,〔(【引用サイトリンク】url=http://apps.who.int/classifications/icd10/browse/2010/en#/K03.8 )〕 dentin sensitivity,〔(【引用サイトリンク】url=http://www.nlm.nih.gov/cgi/mesh/2014/MB_cgi?mode=&term=Dentin+Sensitivity&field=entry )〕 cervical sensitivity,〔 and cervical hypersensitivity〔) is dental pain which is sharp in character and of short duration, arising from exposed dentin surfaces in response to stimuli, typically thermal, evaporative, tactile, osmotic, chemical or electrical; and which cannot be ascribed to any other dental disease.〔〔〔Canadian Advisory Board on Dentin Hypersensitivity (2003). Consensus-based recommendations for the diagnosis and management of dentin hypersensitivity. Journal of the Canadian Dental Association 69:221-226.〕〔 A degree of dentin sensitivity is normal, but pain is not usually experienced in everyday activities like drinking a cooled drink. Therefore, although the terms ''dentin sensitivity'' and ''sensitive dentin'' are used interchangeably to refer to dental hypersensitivity,〔 the latter term is the most accurate. ==Symptoms== The pain is sharp and sudden, in response to an external stimulus.〔 The most common trigger is cold,〔 with 75% of people with hypersensitivity reporting pain upon application of a cold stimulus.〔 Other types of stimuli may also trigger pain in dentin hypersensitivity, including: * Thermal – hot and cold drinks and foods,〔 cold air, coolant water jet from a dental instrument. * Electrical – electric pulp testers.〔 * Mechanical–tactile – dental probe during dental examination,〔 periodontal scaling and root planing,〔 toothbrushing.〔 * Osmotic – hypertonic solutions such as sugars.〔 * Evaporation – air blast from a dental instrument.〔 * Chemical – acids,〔 e.g. dietary, gastric, acid etch during dental treatments. The frequency and severity with which the pain occurs are variable.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「dentin hypersensitivity」の詳細全文を読む スポンサード リンク
