The Effects of a Denture Cleanser on the Surface Roughness of Heat-Cured and Cold-Cured Acrylic Resins

Abstract

Objective: To evaluate the effects of one denture cleanser on the surface roughness of heat-cured and cold-cured acrylic resin materials. Materials and Methods: Two acrylic resin materials (one heat cured and one cold cured) were used in this study. Twenty diskshaped specimens (10 mm in diameter and 2 mm thick) were prepared from each resin, polished, and stored in water at 378C for 48 hours. Disinfection methods included immersion in an alkaline peroxide effervescent denture cleanser for 5 minutes and then immersion in water at 378C. The disinfection procedures were repeated 60 times in 6 days before submitting the specimens to surface roughness measurements. Control specimens (not disinfected) were kept in distilled water at 378C for 6 days before undergoing surface roughness tests. Statistical analyses of data were conducted with an ANOVA and a Tukey post hoc test (a=0.05). Results: Cold-cured acrylic resin test specimens showed significantly (p,0.001) higher surface roughness values than the heatcured resin specimens, regardless of immersion procedure. No significant change in surface roughness was observed in the heat-cured resin specimens after immersion in the denture cleanser (from 0.061 6 0.013 to 0.063 6 0.08 lm). A small, but significant (p,0.01), decrease in surface roughness value (from 0.120 6 0.015 to 0.094 6 0.012 lm) was observed in the coldcured acrylic resin specimens. Conclusion: Within the limitations of this in vitro study, cold-cured acrylic resin specimens exhibited significantly lower surface roughness values after immersion in the denture cleanser used. Heat-cured acrylic specimens were not affected by the immersion. (Turkish J Orthod 2013;26:92-97)
