Publication Metadata only Evaluation of various denture cleansers on color stability and surface topography of polyetherketoneketone, polyamide, and polymethylmethacrylate(2020-08-01T00:00:00Z) ÖZYILMAZ, ÖZGÜN YUSUF; AKIN, CEYDA; KARA, ÖZLEM; ÖZYILMAZ, ÖZGÜN YUSUF; KARA, ÖZLEMThe aim of this study was to evaluate the effect of sodium perborate effervescent tablets and citric acid solution on the color stability and surface topography of a new generation of high-performance polymer polyetherketoneketone (PEKK), thermoinjection-molded polyamide, and polymethylmethacrylate (PMMA). Fifty disc-shaped specimens were fabricated (10 mm x 2 mm) from PEKK (P group), polyamide (D group), and PMMA (M group). These groups were divided into five subgroups (n= 10) according to the storage media. The test groups were immersed in the following solutions: distilled water (Control), Corega, Protefix, Perlodent, and Curaprox. The color stability values (Delta E) were measured using a spectrophotometer before and after immersion in distilled water and four different denture cleansers for 8 hr/day for 140 days. Topography alterations after treatments were assessed with scanning electron microscopy (SEM). Data were analyzed by one-way analysis of variance (ANOVA) followed by Tukey-s Honest Significant Difference test. Thep < .05 was considered significant. All denture cleansers increased the Delta Evalues relative to the baseline values in the M, D, and P groups (p < .05). The Perlodent denture cleanser demonstrated the highest Delta Evalue in all groups, which was unacceptable. Curaprox denture cleanser showed the lowest Delta Evalue in the M and D groups (p < .05). Curaprox in all groups showed a increment Evalue less than 3.7. For patients who have PEKK- and polyamide-based prosthesis, the use of citric acid-based cleansers may be more recommended than sodium perborate-containing cleansers because of its clinically acceptable color changes on polymers in terms of color stability.Publication Metadata only Rehabilitation of partial and total edentulism with Toronto Bridge Prostheses; 3 case reports.(2021-11-06T00:00:00Z) Sıncı, Aslı; Kara, Özlem; Dolanmaz, Doğan; Özyılmaz, Özgün Yusuf; SINCI, ASLI; KARA, ÖZLEM; DOLANMAZ, DOĞAN; ÖZYILMAZ, ÖZGÜN YUSUF
