title: Color and gloss evaluation of titanium dioxide coating for acrylic resin denture base.
abstract: OBJECTIVE
  We examined the clinical appearance (color, gloss, and surface roughness) of TiO(2) coating on polymethyl methacrylate (PMMA) resin dentures.
  
  
  METHODS
  A spraying method, using air brushes, was used to generate thin uniform TiO(2) coating. PMMA resin, primer-coated PMMA, and TiO(2)-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 TiO(2)-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 TiO(2) coating.
  
  
  CONCLUSIONS
  The thin TiO(2) coating afforded high levels of glossiness while maintaining the color of the denture base material.
