Recently, electrolyzed water (strong acid electrolyzed water and strong alkaline electrolyzed water) has been used for cleaning of the denture.
In this study, the effect of electrolyzed water on the denture base resin, relining materials and dental engineering plastics was investigated.
Three commercially available conventional denture base resin, five denture relining materials and three dental engineering plastics were immersed in electrolyzed water and distilled water for two weeks. Knoop hardness, surface roughness, color and gloss were measured before immersion and 1 and 2 weeks after immersion.
The color changes due to immersion of the denture relining materials increased significantly in all solutions. The color change due to soaking dental engineering plastic in strong acid electrolyzed water was slightly more.
The surface roughness and gloss did not show a significant change in any solution. The Knoop hardness of the denture relining materials decreased after immersion in strong alkaline electrolyzed water.
These results suggested that there are few effects on the property of the denture base resin and that the electrolyzed water can be apply to the cleaning of the denture.
