Comparative evaluation of the efficacy of 2% sodium fluoride with and without iontophoresis in the treatment of hypersensitivity

The enigmatic problem of dentin hypersensitivity has long bewildered the dental profession. Dentin sensitivity is one of the most common, painful, ubiquitous, and least satisfactorily treated menaces confronted in routine by the dentist. Over the years, a wide variety of materials and methods have been tried for the treatment of this malady with varying results. Iontophoresis is one such procedure whereby the desensitizing agents are penetrated deep into the open dentinal tubules with the help of electric current. The present study was carried out to evaluate and compare the effect of 2% sodium fluoride with and without iontophoretic application.
