Effect of photopolymerized glaze application on bacterial adhesion on ocular acrylic resin surfaces submitted to accelerated aging

This study evaluated the influence of photopolymerized glaze application on the roughness of ARs and adhesion ofStaphylococcus aureus andStaphylococcus epidermidis on ocular AR surfaces submitted to accelerated aging. Two hundred and eighty ‐eight samples of white‐color (N1) and colorless ARs were distributed in 8 groups (n = 9), based on surface treatments (glaze or ARs submitted to only a final polishing), accelerated aging (before and after), and periods of microbial growth (24‐ and 48‐hours). The roughness average (Ra) and total height of roughness profile (Rt) values were greater for the groups with glaze and increased for all groups after aging. The microbial adhesion among the groups with and without glaze did not present a statistically significant difference. The aging statistically affected the adhesion ofStaph. aureus, which presented an increase after 24 hours of growth, but did not affectStaph. epidermidis on only N1 AR with glaze. These results demonstrate that the glaze did not contribute to adhesion ofStaph. aureus andStaph. epidermidis, which are responsible for most ocular prosthetic infections.This article is protected by copyright.
