電解水の義歯洗浄効果 細菌学的検討

Abstract

The purpose of this study was to investigate efficacies of acidic and neutral electrolyzed water as denture cleansers from the bacteriological aspect.Twenty-five upper full dentures of patients of an elderly care center were used in this study. Nine dentures were immersed in acidic electrolyzed water, eight in neutral electrolyzed water and eight in denture cleanser (Pika®). Plaque samples were collected from fitting surface of the dentures by scrubbing before and after immersion, and the changes in the number of bacteria were observed.The results were as follows:1. Acidic and neutral electrolyzed water were effective as denture cleansers, and the rates of removal [log10 (bacteria number after immersion)/logic, (before immersion)] tended to be constant.2. MRSA decreased by immersion in acidic electrolyzed water and in denture cleanser (MRSA was isolated from four dentures. Two were immersed in acidic electrolyzed water and two in denture cleanser).
