Authors overview the etiology and pathomechanism of the root hypersensitivity. The most commonly used therapeutical aids and devices are discussed. They discuss the theory of action of the drugs used for controlling root hypersensitivity. In details the dental literature of devices used on the individual bases--included different fluoride compounds, stronciumchloride, and potassium nitrate--are reviewed.
