Abstract
Objectives: This study aimed to compare the translucency characteristics of different shades of 5 composites. Methods: Seven resin discs were prepared from each composite (Grandio, Gradia Direct, Clearfil Majesty Esthetic, Ceram-X Mono, Filtek Z250) and shade (A1, A2, A3). Baseline CIE L*a*b* color coordinates of specimens were measured in a viewing booth with D65 illumination by spectrophotometer (Easyshade Compact, Vita). The translucency parameter was calculated for each specimen. Results were analyzed statistically. Results: Grandio and Gradia were significantly more translucent than Clearfil Majesty Esthetic, Ceram-X Mono and Filtek Z250 for A1 shade. For A2 shade, TP values of Grandio, Gradia and Clearfil Majesty Esthetic were statistically higher than Filtek Z250 and Ceram-X Mono. For A3 shade, Grandio was statistically the most translucent resin among all composites. There was no statistical difference between TP values of Clearfil Majesty Esthetic, Gradia and they were significantly more translucent than Filtek Z250 and Ceram-X Mono for A3 shade (p<0.05). TP values of A3 shade of Grandio were higher than A1 shade. Conclusion: Translucency characteristics of composites may be influenced by the brand in each shade. Information on the relative translucencies of different composites can be useful in selecting the correct composite for the achievement of optimal esthetic results.
