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 Termal ve mekanik yükleme siklusunun self–etch rezin yapıştırma simanının dentine bağlanma dayanımı üzerine etkisi(2017-07-01) KARA, ÖZLEM; SARI, TUĞRUL; ÖZYILMAZ, ÖZGÜN YUSUF; İNAN KURUGÖL, PELİN; KARA, HALUK BARIŞ; KARA, ÖZLEM; ÖZYILMAZ, ÖZGÜN YUSUFPublication 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 YUSUFPublication Metadata only Edentulous Full Arch Fixed Implant Rehabilitation using Hybrid Prostheses: Case Report(2017-05-04T00:00:00Z) Kara, Özlem; Özyılmaz, Özgün Yusuf; Kara, Barış; Delilbaşı, Barış Çağrı; KARA, ÖZLEM; ÖZYILMAZ, ÖZGÜN YUSUFPublication Metadata only Full Arch Rehabilitation of Edentulous Patient with Subperiostal Implant-Supported Overdenture Prosthesis: A Case Report.(2018-05-12) ÖZYILMAZ, ÖZGÜN YUSUF; KARA, ÖZLEM; ERDEM, KÜBRA; ÖZYILMAZ, ÖZGÜN YUSUF; ERDEM, KÜBRA; KARA, ÖZLEMPublication Metadata only Have an effect different bleaching procedures on esthetic ceramic surface’s roughness(2018-10-01) KARA, ÖZLEM; ÖZYILMAZ, ÖZGÜN YUSUF; KARA, ÖZLEM; ÖZYILMAZ, ÖZGÜN YUSUFPublication Metadata only Effect of Thermal and Mechanical Cycling on Dentin Bond Strength(2015-09-03T00:00:00Z) İnan İnegöl, Pelin; Kara, Barış; Sarı, Tuğrul; Özyılmaz, Özgün Yusuf; Kara, Özlem; Üşümez, Aslıhan; ÖZYILMAZ, ÖZGÜN YUSUF; KARA, ÖZLEM
