Cleanser solution effects on denture base resins: Electronmicroscopic investigation

Scanning electron microscopic investigations were conducted to determine morphostructural alterations on denture base resin surfaces after immersions in commercially available oxygen liberating denture cleansers. The topography of properly processed denture resins did not show corrosive effects, whereas inconsistent surface characteristics of improperly processed wet-mix acrylates could suggest less resistance. In spite of thorough rinsing after immersion, deposits were noted on the resins of varying amount, size, and quality according to the cleanser used. A possible clinical relevance of such deposits is yet to be evaluated.
