ABSTRACT
Avoiding biofilm formation on dentures is associated with maintaining the
surface properties of acrylic-based dentures. The aim of the study is to investigate
the effects of two different cleaning agents (Corega and Klorhex 0.2% chlorhexidine
gluconate) on surface roughness of the denture regarding efficacy of curing procedures.
A total of sixty disc-shaped specimens were prepared with two different methods
as long and short curing processes. The specimens were divided into subgroups
according to the immersion solutions (distilled water, Corega tablet group and Klorhex
0.2% chlorhexidine gluconate group) (n=10). The samples were kept in a solution for 8
hours per day during a month. The average Ra (before exposure to the cleanser agent)
and Ra (after exposure to the cleanser agent) of each sample was measured. A twoway ANOVA and post hoc Tukey test was used for statistical analysis. The solutions
significantly increased the Ra values in both acrylic groups (p‹0.001). While the effect
of the distilled water group was significantly lower than Corega and Klorhex in the
long-term curing group (p‹0.05), no significant difference was found in the short-term
curing group (p.05). The long-term curing time is highly effective in decreasing the
surface roughness of the acrylic base material.
