Effectiveness of sodium fluoride on tooth hypersensitivity with and without iontophoresis.

Effectiveness of iontophoresis with and without electric current and sodium fluoride on tooth hypersensitivity was evaluated. In eleven volunteers, teeth received a 2% neutral sodium fluoride solution applied using an electrode phoresor. Test teeth received the solution with current and control teeth received the solution without current.
