Surface pre-reacted glass reinforced dental composite: Performance assessment of physicochemical, static mechanical, dynamic mechanical and wear properties

The purpose of the present study was to introduce S-PRG fillers and vary in the range of (0–15 wt. %) in the dental composites with partial replacement of organic matrix (BISGMA/TEGDMA/CG/EDMAB in 54 wt. %, 45 wt. %, 0.2 wt. % and 0.8 wt. %). The performance of S-PRG fillers was evaluated by testing the S-PRG reinforced dental composite in terms of chemical properties (polymerization shrinkage, degree of conversion), optical (translucency) and mechanical properties (micro-hardness, compression strength, diametral tensile strength and wear properties). It was revealed that the addition of 5 wt. % of S-PRG ceramic fillers increased depth of cure, degree of conversion, polymerization shrinkage and water sorption by 5.12%, 5.6%, 6.5% and 2.96%, respectively. Whereas, on adding 5 wt. % of S-PRG ceramic fillers, Vickers hardness, compressive strength, flexural strength, diametral tensile strength and wear resistance were increased by 25.8%, 11.6%, 15.8%, 25% and 9.6%, respectively. Data were analyzed statistically with one-way ANOVA and post hoc Tukey's HSD test (α < 0.05). This study demonstrates that the biologically beneficial S-PRG ceramic fillers have exhibited excellent performa
