In vitro study evaluates wear, hardness, and strength of flowable composites, highlighting material selection for durability.
Key Points
This study aims to evaluate the wear resistance, microhardness, and compressive strength of high-filled flowable composite resins compared to a conventional resin.
Tested seven composite resins including six high-filled flowable and one conventional.
Prepared 140 specimens for various tests based on resin type.
Measured wear resistance using a tribometer with an Al₂O₃ antagonist under defined conditions.
Assessed compressive strength with a universal testing machine and measured microhardness with a Vickers hardness tester.
Utilized one-way ANOVA and Tukey HSD for statistical analysis.
EUFH, VUF, and OCF exhibited higher wear volumes than FZ250.
FZ250 showed greater microhardness than all high-filled flowable composites.
Compressive strength of high-filled flowable composites was comparable to that of the conventional resin, with variations among the flowables.
