Smoothielerin nano kompozit rezinlerin mikrosertlik ve renk değişimi üzerine etkisi

Amaç: Bu çalışmanın amacı, smoothielerin nano kompozit rezinlerin mikrosertlik ve renk değişimi üzerine etkisini araştırmaktır. Gereç ve Yöntem: İki farklı tipte nano kompozit rezin kullanılmıştır: nano hibrit(Charisma Topaz, Kulzer GmbH) ve supra- nanohibrit kompozit rezin(Estelite Asteria, Tokuyama Corp.) Toplam 120 adet disk şeklinde kompozit rezin örnek, teflon kalıplar (4x2 mm) kullanılarak hazırlanmıştır (N=60). Tüm örnekler, LED ışık cihazı kullanılarak polimerize edilmiş (1000 mW/cm2) ve bekletilme içeceklerine göre 4 alt gruba ayrılmıştır: pembe smoothie, avokadolu smoothie, portakal suyu ve distile su. İçeceklerde bekletilme öncesi ve sonrası, mikrosertlik değerleri (n=5), Vickers sertlik cihazıyla ve renk değerleri( n=10) ise spektrofotometre ile ölçülmüştür. Mikrosertlik ve renk değişim verileri, Kruskal Wallis, Dunn, iki yönlü varyans ve Bonferroni testleri kullanılarak değerlendirilmiştir (p

The effect of smoothies on the microhardness and color change of nano composite resin

Aim: The purpose of this study was to investigate the effect of smoothies on the microhardness and color of nano composite resins. Materials and Method: Two different nanocomposite resins were used: nanohybrid (Charisma Topaz, Kulzer GmbH) and supra-nanohybrid composite resin(Estelite Asteria, Tokuyama Corp.). Total 120 disc-shaped composite resin specimens were prepared using teflon molds (4x2 mm) (N=60). All specimens were polymerized with LED light curing unit(1000mW/cm2) and subdivided into 4 groups according to the immersion beverages: pink smoothie, avocado smoothie, orange juice and distilled water. Before and after immersion in beverages, Vickers hardness tester and spectrophotometer were used to measure the microhardness (n=5) and color (n=10) values. Microhardness and color change data were analyzed with Kruskal Wallis, Dunn, two-way variance and Bonferroni tests (p
