Electrozone consists of a fluid which is nothing but sea or salt water subjected to an electrolytic current. It is a clear liquid, neutral in reaction, with the odor of free chlorine, and a disagreeable, salty taste. It was discovered by A. E. Woolf, who has succeeded in sterilizing polluted water with it on a large scale.
Dr. C. F. W. Bodecker recommends electrozone as an efficient antiseptic, and claims that it has given him uniformly satisfactory results in the treatment of purulent pulpitis. His method is to open the pulp-chamber freely, and then syringe with tepid water. The electrozone is then introduced into the pulp-chamber on a small piece of cotton saturated with it, followed by one or two smaller pledgets moistened with the electrozone. The patient is then directed to renew only the last piece of cotton, from three to five times daily, or at least after every meal, using the precaution to rinse the mouth with a weak solution of electrozone (about a teaspoon-ful in a tumbler of water) previous to the removal of the cotton.
Every pledget of cotton, previous to its introduction, should be moistened with pure electrozone, and packed as tight in the cavity of the tooth as possible. When the tooth has been treated in this manner for two or three days, the pulp-canal may be cleaned out and filled at once, without any fear of future pericementitis, provided that an infection of pericementitis has not already occurred.
