Clinical management of dentin hypersensitivity using cathode and anode iontophoresis.

A clinical study was undertaken to study the desensitising effect of Anode and Cathode iontophoresis using solutions and gels. A total number of sixty patients were selected, divided into four groups and subjected to the following methods of treatment. a) Anode Iontophoresis using strontium Chloride Solution (9%) b) Anode Iontophoresis using Strontium Chloride gel (9%) c) Cathode Iontophoresis using Sodium Fluoride solution (2%) d) Cathode Iontophoresis using Sodium Fluoride gel (2%) Distilled water was used as the control Sensitivity was evaluated objectively with the help of specially designed apparatus which delivered measurable electrical stimuli. The results showed a statistically significant difference in the reduction of tooth sensitivity using Strontium Chloride (9%) both as a gel and solution as compared to Sodium Fluoride (2%) gel and solution.
