Dentin hypersensitivity (DH) is defined as short and sharp pain caused by external stimuli such as heat, vaporization, contact, osmotic pressure, and chemical stimulation in a normal tooth, rather than due to disease or tooth damage. Its solution is to block the flow of dentinal fluid by physically blocking the dentinal tubule. Of these treatments, fluoride and oxalate type for hypersensitivity can only have a temporary effect. Resins should be used with a suitable bonding system and they may cause hypersensitivity symptoms after treatment. Overcoming these limitations, there is a need for method that can effectively treat dental hypersensitivity lasting long without any side effects. For this reason, experiments with 200 plant extracts as candidates for dentin hypersensitivity, Buddleja officinalis was considered as a candidate for present study. The purpose of this study is to confirm whether the ethanol extract of Buddleja officinalis is effective to protect enamel and dentin by coating tooth surface and resistance to acid or alkali even after tooth coating.
