Abstract
Mouth-rinsing with oxydized water containing electrolytically generated chlorine has been shown to hinder dental plaque formation. However, mouth-rinsing has been associated with the problem of accelerating the deterioration of metallic restorations in the mouth. This study was undertaken to provide information necessary to evaluate the effects of rinsing by measuring the electrode potentials of metallic restorations in clinical situations.
The subjects consisted of 21 healthy volunteers between 23 and 40 years of age. Each subject was given 10ml of the oxydized water, asked to rinse vigorously for 10 seconds and repeat rinsing three times. Electrode potential measurements on all of the metallic restorations in the mouth were made before and immediately after each rinsing with a simple device equipped with a platinum microprobe.
In all cases mouth-rinsing with the oxydized water shifted the electrode potential of the metallic restorations in the mouth toward noble values, indicating oxidation. This finding suggested that, although the extent of the oxydation was unknown, proper utilization of oxydized water is of particular importance.
Further investigations are needed to fully develop and evaluate the potential of this mouth-rinsing.
