It was concluded that considering the color stability and surface roughness, many cleaning procedures can be used safely for PEEK polymers. Also, no significant difference was observed for R a0, R a1, and ΔE 00 values between the test groups ( P > .05). ![]() For both R a and ΔE 00 values, the effect of the cleaning method was not statistically significant ( P > 0.05). For all test groups, R a0 and R a1 values were lower than the plaque accumulation threshold level (PATL) of 0.200 μm. Color differences were calculated, and data were statistically analyzed with one-way ANOVA and the Tukey HSD test ( α = .05). CIELab color parameters of each specimen were measured with a spectrophotometer before and after 7 days of storage in a coffee solution. The surface roughness values ( R a) were measured with a profilometer before ( R a0) and after cleaning procedures for 270 days ( R a1). Other three groups were subjected to daily cleansing with denture cleaners (5% sodium hypochlorite, alkaline peroxide, chlorhexidine gluconate solution) and the other three groups were subjected to mechanical cleaning with a toothbrush with three different dentifrices (toothpaste, soap, and denture cleansing gel). One of these groups subjected to distilled water was the control group. ![]() Seventy disk-shaped (10 × 3 mm) specimens were fabricated and divided into seven groups ( n = 10) according to the cleaning procedure. In this study, the effect of different denture cleaning methods on the surface roughness and color stability of polyether ether ketone (PEEK) dental materials was studied. Dental prostheses are cleaned during their service life, and surface roughness is an important criterion for these polymeric materials. Polymeric materials are inevitably used in dental applications.
