The load and size of the indentation may affect the hardness value. This study investigated the effect of the indentation size on the microhardness of one resin-based composite (RBC). Metal molds 4 mm deep and 12 mm in diameter were filled with Tetric EvoCeram Bulk Fill (Ivoclar) and light-cured for 10 s using a broad-spectrum LED curing light. The Vickers microhardness and the degree of conversion (DC) at the top and bottom surfaces were measured 24 h later before and after polishing the RBC. The microhardness measurements were made using 50, 100, 300 and 1000-gf loads with the same 8 s dwell time. The DC was measured in the same region using mid FT-IR spectroscopy. Repeated measures analysis of variance tests were used to determine if the surface (top vs. bottom) or the indenter loads had a significant effect on the VH, or if polishing affected the VH and the DC (alpha = 0.05). It was found that the indenter load did not affect the Vickers hardness of the unpolished top surface (p = 0.759), the polished top surface (p = 0.374), or the polished bottom surface (p = 0.083) of the Tetric EvoCeram Bulk Fill. Increasing the indenter load did increase the VH of the unpolished surface at the bottom (p < 0.0001). Polishing increased the DC by 13.5% at the top and by 46.7% at the bottom surface.

Aims: The focus of this review is to assess the mechanical characteristics of using nanoparticles (NPs) in dental composites (DCs) to enhance strength and toughness. Materials and Methods: The review protocol was registered on PROSPERO with registration ID: CRD42024573647. A systematic search for relevant articles published between 2018 and July 2024 was conducted across electronic databases including Scopus, PubMed, WoS, and EBSCOhost. Studies meeting pre-defined eligibility criteria were included and assessed for methodological quality. Data on the mechanical properties of NPs on DCs were extracted from included studies. Meta-analysis was performed to assess the mechanical flexure strength associated with NPs in DCs. Results: A range of NPs including silicon dioxide, zirconium dioxide, titanium dioxide, graphene oxide, core–shell chlorhexidine/amorphous calcium phosphate, zinc-doped mesoporous silica NPs, silver NPs, farnesol-loaded halloysite nanotube, calcium hydrogen phosphate dihydrate, niobium pentoxide, and chitosan were examined for incorporation into DCs. The use of organic and inorganic NPs has shown a significant boost in the mechanical characteristics of DCs. The forest plot demonstrated a significant increase in mechanical characteristics in DCs infused with NPs. Conclusion: It can be concluded that incorporating NPs in restorative dentistry holds promise for enhancing their mechanical properties and increasing strength and toughness.
