This was passed to the bottom of thepockets between the teeth and 3 to 5 ma. current passed forhalf a minute to two minutes. The gingival trough wasionized by slowly moving the electrode out of the deeperpockets around the necks of the teeth, every part of thetissues comprising the trough was treated. Treatment wascarried out every second day, most attention being given topockets which were deepest, and from which pus could beexpressed. Four crowns and a faulty filling shown in Fig. 152. and 153 were removed, these being the chief cause of sepsisin the molar region. In every instance after the removal ofthe irritant cause and ionization, pus ceased and conditionimproved. Treatment was kept up until the gingival troughwas perfectly healthy; and bleeding, which at first was exces-sive, completely ceased even when instruments were forciblypassed under the contracted gingival border.
