A novel resin-based bulk-fill restorative material (ST; Stela SDI, Bayswater, Victoria, Australia) has been recently introduced as a self-curing alternative to traditional light-cured composites. Promoted for its unlimited depth of cure, enhanced aesthetics, and unique primer composition, it aims address challenges associated with amalgam light-curing Thus, the aim this in vitro study was investigate performance new polymer-based material, ST, compared two conventional composites direct restoration. The evaluated compressive strength without aging, antibacterial activity, mineral deposition contact Phosphate-Buffered Saline (PBS) artificial saliva, porosity, wettability ST (Tetric EvoCeram (TE; Ivoclar Vivadent, Schaan, Liechtenstein) Clearfil Majesty ES-2 (CM; Kuraray Noritake Dental, Tokyo, Japan)). data statistically analyzed (α = 0.05) through one-way two-way analysis variance (ANOVA). demonstrated significantly higher than TE CM at baseline after aging (p < 0.001), while reduced across all materials 0.001).
