Abstract

Abstract: Purpose: We examined the clinical appearance (color, gloss, and surface roughness) of TiO2 coating on polymethyl methacrylate (PMMA) resin dentures. Methods: A spraying method, using air brushes, was used to generate thin uniform TiO2 coating. PMMA resin, primer-coated PMMA, and TiO2 -coated PMMA (with primer) specimens were compared. Results: The Commission Internationale de l'Eclairage (CIE) color system revealed color variations between the with/without coated samples. The TiO2 -coated PMMA specimen displayed high levels of glossiness, highlighting the efficient self-cleansing actions of the denture. The measured surface roughness decreased upon primer coating, and increased following TiO2 coating. Conclusions: The thin TiO2 coating afforded high levels of glossiness while maintaining the color of the denture base material.
