Application of Platinum and Titanium Materials as an Electrode for Hygiene Purpose

Abstract

The aim of this study was to investigate the application of electrochemical technology in relation to the electrolysis of water in specific fields, including mouthrinses for the control of periodontal disease and the cleaning of contact lenses. A platinum (Pt) coated titanium (Ti) electrode cell (Pt/Ti cell, Dolki Korea Ltd.) was used for electrochemical experiments. Using the disinfection or oxidation potential of the Pt/Ti cell, sterilized water was prepared for clinical testing. An experimental group used mouthrinses with the sterilized water, where as the control group did not. In the experimental group, the gingival and plaque indices, the probing pocket depth and clinical attachment level all showed statistically significant decreases, but in the control group showed significant increases (P<0.05). The electrochemical sterilization of water using the Pt/Ti cell was also applied for the cleaning of contaminated contact lenses. SEM (Scanning Electron Microscope) data demonstrated that a foreign body adhered to the contract lens could be removed during the electrolysis of water containing the contaminated contact lens.
