Comparative evaluation of wear resistance of cast gold with bulk-fill composites an in vitro study

Aim: The aim of this study was to compare the wear resistance of cast gold with condensable bulk fill and a fiber reinforced bulk-fill composite. Materials and Methods: The 5 mm × 4 mm stainless steel molds were prepared for wear resistance. Forty-five samples were divided into three groups (n = 15)...

Description
Summary:Aim: The aim of this study was to compare the wear resistance of cast gold with condensable bulk fill and a fiber reinforced bulk-fill composite. Materials and Methods: The 5 mm × 4 mm stainless steel molds were prepared for wear resistance. Forty-five samples were divided into three groups (n = 15). The samples were restored as follows: Group I: cast gold alloy (d. SIGN 98; Ivoclar Vivadent), Group II: fiber reinforced composite (Ever X Posterio; r GC Corp.), and Group III: condensable bulk-fill composite (Tetric N Ceram; Ivoclar Vivadent). A pin on disc wear tester was used to measure the wear resistance. Data were analyzed using one-way analysis of variance. Results: Higher statistically significant values were seen for the cast gold restorations than the other two bulk-fill composites. Conclusion: It is desirable for any restorative material to yield wear behavior. D. SIGN 98 (Type IV cast gold alloy) was the most wear resistant material tested, whereas Tetric N Ceram (condensable bulk-fill composite) was the least wear resistant.
