Amaç: Bu çalışmanın amacı; ofis ve ev tipi ağartma materyallerinin, klinikte sıklıkla kullanılan yedi farklı restoratif materyalin yüzey pürüzlülüğü ve yüzey sertliği üzerine etkilerini in vitro olarak incelemektir. Gereç ve Yöntemler: Ofis tipi (Opalescence Boost PF %40) ve Ev tipi (Opalescence PF % 16) ağartma materyalleri; disk şeklinde (2x10 mm) hazırlanmış, A2 renginde mikrohibrit (Gradia Direct Anterior), nanohibrit (Clearfil Majesty Esthetic), mikrofil (Renamel) ve nanoseramik içeren (Ceram-X-One Universal) kompozit rezin, kompomer (Dyract XP), rezin modifiye cam iyonomer siman (Fuji II LC) ve geleneksel cam iyonomer siman (Fuji IX) yüzeyine üretici firma talimatları doğrultusunda uygulanmıştır. Ağartma uygulanmayan kontrol grubu dahil 3 uygulama grubu ve 7 restoratif materyal grubu ile toplam 21 adet grup (n=10) oluşturulmuştur. Kontrol grubu yapay tükürük içerisinde bekletilmiştir. Örneklerin yüzey pürüzlülüğü Profilometre cihazı (Perthometer M2, Mahr, Almanya) ve yüzey sertliği de Knoop mikrosertlik cihazı ile ölçülmüştür. Yüzey özellikleri SEM analizi ile kalitatif olarak incelenmiştir. Verilerin istatistiksel analizi iki yönlü ANOVA ve Tukey çoklu karşılaştırma testi ile yapılmıştır. Bulgular: Ev tipi ağartma, yüzey pürüzlülüğünü Fuji II LC grubunda anlamlı derecede artırırken, Fuji IX grubunda anlamlı derecede azaltmıştır (p0,05). Test grupları arasında yüzey sertliği bakımından anlamlı derecede fark bulunmuştur (p0,05). Sonuç: Yüzey pürüzlülüğünde sonuçlar restoratif materyalin yapısına, ağartma materyaline, uygulama süresine bağlı olarak değişmektedir. Yüzey sertliği ise ağartma materyallerinden etkilenmemiştir.

Objective: The aim of this in vitro study was to evaluate the effects of office and home bleaching materials on the surface roughness and surface hardness of seven different restorative materials which are commonly used in the dental clinics. Material and Methods: Office type (Opalescence Boost PF 40%) and Home type (Opalescence PF 16%) bleaching materials applied on disc (2×10 mm) in A2 color microhybrid (Gradia Direct Anterior), nanohybrid (Clearfil Majesty Estetic), microfil (Renamel) and nanoceramic based (Ceram-X-One Universal) composite resin, compomer (Dyract XP), resin modified glass ionomer cement (Fuji II LC) and conventional glass ionomer cement (Fuji IX). A total of 21 groups (n=10) were formed with 3 treatment groups including non-bleaching control groups and 7 restorative material groups. The surface roughness were calculated by aprofilometer and surface hardness calculated by a Knoop microhardness device and analyzed by. SEM. Statistical analysis was performed by two-way ANOVA and Tukey multiple comparison test. Results: Home bleaching caused a significant increase in surface roughness in the Fuji II LC group and a significant decrease in the Fuji IX group (p0.05). A significant difference in surface hardness was found between the test groups (p0.05). Conclusion: Surface rougheness is depending on the restorative and bleaching material. Hardness is not affected by bleaching materials.
