Assesment of the compressive strength of the current restorative materials

Objective: The purpose of this study was to evaluate the compressive strength of the 6 different restorative materials which are frequently used today by using the universal compressive strength test. Materials and method: A total of 60 specimens were prepared as 10 samples in each group for compressive strength test. Group A: G-aenial Posterior Composite Group B: Equia Fil, Group C: Tetric Evo Ceram Bulk Fill, Group D: Glass Fill, Group E: FiltekTM Bulk Fill, Group F: SureFil SDR Bulk Fill. The compressive strength test was performed at a speed of 1.00 +/- 0.05 mm/min along the long axis of the specimens using a computerized universal test device (Autograph AG-IS; Shimadzu Co, Kyoto, Japan). One Way Anova and Tukey HSD test were used for the statistically analysis. Results: The analysis of the obtained data revealed that the highest compressive strength was found in Group F and the lowest compressive strength in Group C and D. The compressive strength of Group F was significantly higher than the other groups (p < 0.01). The compressive strength of Group E was significantly higher than all other groups except Group F (p < 0.01). Conclusions: The use of bulk fill composites in pediatric dentistry provides convenience by shortening the process steps. Thanks to their mechanical properties, they are used in treatment options instead of conventional composite restorations. (C) 2021 Japanese Society of Pediatric Dentistry. Published by Elsevier Ltd.
