A method to apply anodal electrotonus during the cavity preparation in labiocervical cavities was presented. The amount of the electrotonus through a separate different electrode was determined to the maximum allowable current which ranged between 0.1 and 1.5 mA. In 35 teeth from 22 patients, analgesia, starting from the introduction of anodal tonus to the end of the cavity preparation, was observed in 22 (63%) teeth.
