Corrosion of a dental acrylic resin by alkaline peroxide used for cleaning

: Some clinical observations have brought the authors to suspect a corrosion of acrylic resins by an alcaline peroxide (Steradent) proposed as a denture cleanser. By way of a laboratory simulation they have shown that standardized samples of Lucitone 199 are corroded by the main active agents issuing from Steradent: oxygen and a high level of alcalinity. A daily use of Steradent can thus badly affect the physical properties of denture acrylic bases.
