摘      要：Aim of the present in vitro study is to evaluate the radiopacity levels of composite resins with various shades and viscosity.10 mm×2 mm discs were prepared from 7 condensable and 4 flowable composites(n=10).An aluminum step wedge ranging from 2.0 to 10.0 mm in thickness was placed on the occlusal *** radiographs were taken using a dental X-ray device and radiographic densities of each step of the aluminum wedge and the samples were recorded to the *** readings were taken and means were ***-Way Anova and Tamhane post hoc tests were *** G-eanial Posterior has the highest radiopacity value followed by Filtek Z550,Aelite Flo has the lowest radiopacity *** composites show higher radiopacity and flowable composites with higher filler loadings have superior radiopacity levels to condensable *** and body shades of the composite brands have also statistically significant differences in radiopacity ***,radiopacity level of a composite resin material is not affected by the size of fillers;however,the composition,shape and loading of the fillers can specify the radiodensity.
