Various desensitizing agents have been used in clinics to solve the problem of dentinal hypersensitivity (DH), but none of them has been shown to be consistently effective. We here introduce a new type of desensitizing agent, i.e. 4% magnesium sulphate with iontophoresis at 2mA for 3 min. These optimal conditions were determined by animal experiments, while only a minor effect on dentinal issues was observed within 4 weeks after the treatment. When this desensitizing agent was used to treat DH, the cure rate of 62.4% remained steady within the 25-week observation period, while some effect was achieved in all the subjects who participated in the study.
