“…In the current study, cola did not create as much discoloration as coffee in any of the materials, although it has a lower pH 2.5, which is potentially more deleterious than coffee (pH 5.4). The reason could be the yellow colorants in coffee that are absorbed in the body of the materials and penetrate into the organic phase of the materials . In agreement with the results of our study, coffee has been reported as the most severe staining drink in other studies .…”

“…For instance, the highest Ra value for Rok was shown in coffee, while for Filtek Z250, it was observed in cola. Because roughness is a surface property, it is affected by water sorption, which is a complex phenomenon and is dependent on the matrix resin, filler, and interfacial bonding between particles and matrix . Decreased filler loading has been shown to result in greater water absorption .…”

“…Because roughness is a surface property, it is affected by water sorption, which is a complex phenomenon and is dependent on the matrix resin, filler, and interfacial bonding between particles and matrix . Decreased filler loading has been shown to result in greater water absorption . Other parameters, such as differences in shape, hardness, distribution, and amount of particles, could contribute to the Ra of materials.…”

“…Bu etki ise kahve içerisindeki daha az polar özellikte olan renklendiricilerin kompozit içerisine derin bir şekilde penetre olmasıyla açıklanmıştır (25). Kahve içerisindeki bu sarı renklendiriciler rezin kütlesi tarafından absorbe edilip organik matriks içerisine penetre olarak renklenmeye sebep olmaktadırlar (26). Bu çalışmada da beyazlatma sonrası bu pigmentler oksidasyona uğradıkları için renk değişiminin kahvede bekletilen örneklerde bu kadar fazla olduğu kanaatindeyiz.…”

ÖZAmaç: Çalışmada ofis tipi beyazlatmanın renklendirilmiş nano-hibrit ve dişeti rengindeki kompozit örneklerinin renk değişimi üzerine etkileri incelenmiştir. Gereç ve Yöntemler: Bu çalışmada bir adet nanohibrit kompozit rezin (Filtek Z550, 3M ESPE) ve bir adet dişeti rengi kompozit (Amaris Gingiva, Voco) kullanıldı. Her bir rezin materyal için 20 adet 5 mm çapında 2 mm kalınlığında disk şeklinde numune hazırlanıp, rastgele seçim yapılarak iki grup oluşturuldu (n= 10). Numuneler distile su ve kahve solüsyonları içeren kaplarda 30 gün boyunca bekletildi. Bu sürenin sonunda numuneler bekleme kaplarından çıkarılarak distile su ile yıkandıktan sonra Hidrojen Peroksit içeren ofis tipi beyazlatma ajanı (Opalescence Boost %40 PF, Ultradent Products.) ile beyazlatma işlemine maruz bırakıldı. Birinci renk ölçümü renklendirme işleminden sonra, ikincisi ise beyazlatma işlemi sonrası bir spektrofotometre cihazı kullanılarak yapıldı. Elde edilen renk ölçümleri için CIE L*a*b* sistemi kullanıldı ve tüm disklerdeki renk değişimleri (ΔE*) hesaplandı. Renk ölçümü her numune için 5'er kez tekrarlandı ve ortalaması alındı. Elde edilen verilerin istatistiksel analizi için bağımsız t-testi kullanıldı (p<0,001). Bulgular: Su veya kahve ile renklendirilen kompozit örneklerinde beyazlatma işleminden sonra meydana gelen renk değişikliği istatistiksel olarak anlamlı bulunmuştur (p<0,001). Fakat sadece Z550 kompozitin suda bekletilen örneklerin beyazlatmadan sonraki renk değişimi klinik olarak tespit edilebilen eşik değerin (ΔE > 3,3) altında bulunmuştur. Sonuç: Ofis tip beyazlatma ajanı, bu çalışmada test edilen Filtek Z550 ve Amaris Gingiva kompozit rezinden renklenmeleri etkili bir şekilde kaldırabilir. ABSTRACTObjective: To evaluate the effects of in-office bleaching on the color changes of colored nano-hybrid and gingiva-shade composite samples Material and Methods: In this study, one nano-hybrid composite resin (Filtek Z550, 3M ESPE) and one gingiva-shade composite resin (Amaris Gingiva, Voco) were used. Twenty-eight disk-shaped specimens were fabricated for each resin material and randomly divided into two groups (n = 20). The specimens were immersed in coffee or deionized water, respectively, for 30 days. Each group was then equally divided into two sub-groups (n = 10), which were subjected to in-office hydrogen peroxide bleaching agent Opalescence Boost PF 40%, Ultradent Products). The color of the specimens was measured by a spectrophotometer after staining and after bleaching. The CIE L*a*b* system was used for color measurement and the color variations (ΔE*) on all discs were calculated. Color measurements were repeated 5 times and the color differences were calculated. The independent t-test was used for statistical analysis of the data (p<0.001). Results: The color changes in the composite samples which were colored with water or coffee were found to be statistically significant after the bleaching process (p<0.001). However, only the color change of Z550 composite immersed in water was found to be below the clinically detect...

Impact of bleaching agents on water sorption and solubility of resin luting cements

Abstract: Sorption and solubility behavior of the studied cements were highly correlated and significantly affected by applying either office or home bleaching agents; seT showed the highest sorption and solubility, whereas Rely X Unicem revealed the lowest.
