Purpose: The aim of this study is to evaluate as a vitro the impact of CAD/CAM resin nano ceramics (Lava Ultimate; 3M ESPE) and nano hybrid composite resin (Grandio/VOCO) materials that are exposed to long-term coloring drinks and then the application of a 24-hour and 72-hour whitening mouth gargarage on color stability. Tool and Method: This study used 20 samples of RNC (Lava Ultimate; 3M ESPE) and 20 samples of nano-hybrid composite resin (Grandio/VOCO) produced by CAD/CAM method. All samples (n=40) were first kept in 12 days of energy drinks and then again in 12 days of tea in two different coloring drinks. After the coloring process, all of the samples were kept in the Listerine Advanced White (Johnson & Johnson, UK) whitening mouth care gargarage waiting for the whitening process.The beginning, after the coloring process and 24 and 72 hours after the whitening process, the colour measurements of the samples were made using the Vita Easyshade V spectrum (Vita Easyshade V, Vita Zahnfabrik, Bad Sackingen, Germany).®®RNC (Lava Ultimate; 3M ESPE) and nano-hybrid composite resin (Grandio/VOCO) samples have been calculated by using the CIELAB ΔE formula for the pre- and after-colored process (ΔE) and the pre- and after-colored process for 24 to 72 hours.The statistical analysis was performed with one-way variance analysis (ANOVA). (p=0,05) Results: after coloring; the average ΔE value of the RNC (Lava Ultimate; 3M ESPE) samples is calculated within clinically acceptable limits, while the average ΔE value of the nano-hybrid composite (Grandio/VOCO) samples is above clinically acceptable limits. When compared the average ΔE values of both groups, statistically significant differences were found (p≤0,05). A statistically significant decline in the average ΔE values of both groups was also observed after waiting for 24 and 72 hours in the whitening oral gargar (p≤0,05). The result: Nano-hybrid composite resin (Grandio/VOCO), according to RNC (Lava Ultimate; 3M ESPE), is colored at a clinically unacceptable level. As a result of 24 and 72 hours of waiting in the mouth gargarage, both materials had a significant decline in statistically (ΔE) values. This result shows that the whitening mouth gargarage provides effective whitening in the materials of the nano-hybrid composite resin (Grandio/VOCO) and RNC (Lava Ultimate; 3M ESPE). The effect of whitening mouth rinse on the color stability of resin nano ceramic and nano hybrid composite stained with colored beverages Abstract Aim: The aim of this study was to determine the effect of application of whitening mouth rinse for 24 h and 72 h on the color stability of CAD/CAM resin nano ceramic (Lava Ultimate; 3M ESPE) and nano hybrid composite resin (Grandio/VOCO) that stained with colored beverages in vitro. Material and Methods: RNC (Lava Ultimate; 3M ESPE) (n=20) and nano hybrid composite (Grandio/VOCO) (n=20) were prepared. All specimens were immersed in energy drink for 12 days and tea for 12 days again. After staining procedure the stained specimens were immersed in Listerine Advanced White (Johnson & Johnson, UK) whitening mouth rinse.Initially, after staining procedure and two times after bleaching procedure first 24 hours later than 72 hours later, the color was measured with Vita Easyshade V spectrophotometer.®The color difference before and after staining and after 24 hours and 72 hours bleaching was evaluated by CIELAB ΔE formula.The data were analyzed with one-way ANOVA (p=0,05).Results: After staining; the calculated avarage ΔE value of RNC (Lava Ultimate; 3M ESPE) samples' was clinically acceptable but the calculated avarage ΔE value of the nano hybrid composite (Grandio/VOCO) samples' was above the acceptable level. When the avarage ΔE values of the groups were compared the difference was statistically significant (p≤0,05). When the avarage ΔE values of the groups were compared after bleaching with the mouth rinse for 24 and 72 hours, decrease in ΔE values was statistically significant (p≤0,05). Conclusion: Nano hybrid composite resins (Grandio/VOCO) were stained above the clinical acceptance level. After bleaching with the mouth rinse for 24 and 72 hours, ΔE values were statistically significantly decreased that means that whitening mouth rinse effectively bleached both RNC (Lava Ultimate; 3M ESPE) and nano hybrid composite (Grandio/VOCO).

Özet:

Amaç: Bu çalışmanın amacı CAD/CAM rezin nano seramik (Lava Ultimate; 3M ESPE) ve nano hibrit kompozit rezin (Grandio/VOCO) materyallerin uzun süre renklendirici içeceklere maruz kalmalarının ve sonrasında 24 ve 72 saatlik beyazlatıcı ağız gargarası uygulanmasının renk stabilitesi üzerine etkisininin vitro olarak değerlendirilmesidir. Gereç ve Yöntem: Bu çalışmada CAD/CAM yöntemi ile üretilen 20 adet RNC (Lava Ultimate; 3M ESPE) ve 20 adet nano hibrit kompozit rezin (Grandio/VOCO) numune kullanıldı. Tüm numuneler (n=40) önce 12 gün enerji içeceğinde, sonrasında da yine 12 gün çayda olmak üzere iki farklı renklendirici içecekte bekletildi. Renklendirme işlemi sonrasında numunelerin tümü Listerine Advanced White (Johnson&Johnson,  İngiltere) beyazlatıcı ağız bakım gargarasında bekletilerek beyazlatma işlemine tabii tutuldu. Başlangıç, renklendirme işlemi sonrasında ve beyazlatma işlemi sonrasında 24 ve 72 saat sonra  numunelerin renk ölçümleri Vita Easyshade® V spektrofotometre (Vita Easyshade® V, Vita Zahnfabrik, Bad Sackingen, Almanya) kullanılarak yapıldı. RNC (Lava Ultimate; 3M ESPE) ve nano hibrit kompozit rezin (Grandio/VOCO) numunelerin renklendirme işlemi öncesi ve sonrası arasındaki renk farklılıkları (ΔE) ile beyazlatma işlemi öncesi ve 24 ile 72 saat sonrası arasındaki renk farklılıkları CIELAB ΔE formülü kullanılarak hesaplandı. İstatistiksel analizler tek yönlü varyans analizi (one-way ANOVA) ile yapıldı. (p=0,05) Bulgular: Renklendirme sonrası; RNC (Lava Ultimate; 3M ESPE) numunelerin ortalama ΔE değeri klinik olarak kabul edilebilir sınırlar içerisinde hesaplanırken nano hibrit kompozit (Grandio/VOCO) numunelerin ortalama ΔE değeri klinik olarak kabul edilebilir sınırların üzerinde yer almaktadır. Her iki grubun ortalama ΔE değerleri karşılaştırıldığında ise istatistiksel olarak anlamlı farklılık bulunmuştur (p≤0,05). Her iki grubun ortalama ΔE değerlerinde 24 ve 72 saat beyazlatıcı ağız gargarasında bekleme sonrasında da istatistiksel olarak anlamlı bir düşüş görülmüştür (p≤0,05). Sonuç: Nano-hibrit kompozit rezin (Grandio/VOCO), RNC (Lava Ultimate; 3M ESPE) ‘e göre klinik olarak kabul edilemez düzeyde renklenmektedir. 24 ve 72 saatlik beyazlatıcı ağız gargarası içerisinde bekletilmesi sonucunda her iki malzemede de istatistiksel olarak (ΔE) değerlerinde anlamlı düşüş bulunmuştur. Bu sonuç beyazlatıcı ağız gargarasının nano hibrit kompozit rezin (Grandio/VOCO) ve RNC (Lava Ultimate; 3M ESPE) malzemelerinde etkin bir beyazlatma sağladığını göstermektedir.
