The Effect of Some Traditional Beverages on the Colour Stability of the Resin Nanoceramic Material

Aim: The aim of this study was to analyse the colouring effect of traditional Turkish beverages, which are frequently consumed in our society, on CAD/CAM resin nano ceramic block Material. Methods: A total of 20 samples were used resin nanoceramic CAD/CAM blocks (Cerasmart.GC Corporation, Tokyo, Japan) with dimensions of 12x10x2 mm3 . The surfaces of all samples were polished with 800, 1000 and 1200 grit silicon carbide abrasives (3M, St. Paul, USA) and rinsed. The specimens were randomly divided into 4 groups (n=5). The initial color values and time dependent color changes of the samples on 1st, 3rd and 7th days were recorded using a dental spectrophotometer (VITA Easyshade Advance 4.0, Vita Zahnfabrik, Germany). Statistical data were analysed using with the R WRS2 package (Wilcox & Schönbrodt, 2015). Significance level was taken as p
