Objective. Evaluate the roughness and color stability of different types of resins used to
immerse denture bases in various denture cleansers overnight.
Metodology. A total of 150 resin samples were made, which were divided into 3 groups of
denture resin (conventional thermally activated, milled and 3D printed) (n= 50) and
subdivided into 5 denture cleaners (Distilled water, Corega Tabs, Efferdent, NaOCl 1.0%,
Listerine Cool Hint) (n= 10). The roughness properties (Ra) and chromatic difference (ΔE00)
were evaluated during 90 days and 180 days of overnight cleaning. Data were evaluated by
two-way ANOVA and Tukey's test for multiple comparisons (P<.05).
Results. Listerine had significantly higher Ra and ΔE values (P<.001) compared to other
solutions, being significant in conventional resin at 180 days (P<.001).
Conclusions. The use of Listerine as an overnight cleaner presents greater damage to the
optical and surface properties of denture base resins, mainly with conventional resin, with 1%
NaOCl being a valid option in relation to cost-benefit.
