The dentinary hipersensitivity is caracterizad by ana cute and short duration pain produced by the exposition of dentine to termal, evaporatorios, tactile, osmotic or chemical stimulants, that can not be atribuited to any pathology or dental detect. It is considerated to have a multifactorial etiology. The theory that best explains the aparition of dentinary sensibility is the hydrodinamic one proponed by Brannström. The etiological factors mostly related to dentinary hypersensitivity are: root planning treatment, adhesive restorations, dental erosion, abrasion, abfraction and whitening.
