Hypersensitive dentin is an important problem that should be controlled in the clinical fields of preventive dentistry, prosthodontics, and fillings, and especially in patient care in periodontal surgery cases. According to hydrodynamic theory of Brännström, several therapeutic methods have been applied, such as glassionomer cement filling, fluoride application, and protein coagulation. However, such treatments do not sufficiently relieve a patient's various discomforts derived from hypersensitivity of dentin.<BR>We carried out a clinical study on the effect of jelly containing zinc sulfate and aluminum chloride for these discomforts in comparison with that of a control jelly containing NaF.<BR>The reaction towards cold water was improved to 81.8 % for persons and 86.4% for individual teeth (P<0.05). The effects were also observed in the reactions towards cold air and scratching, without any side effects.
