文摘

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.
