Objectives Resin-based materials are applied in every branch of dentistry. Due to their tendency to release substances in the oral environment, doubts have been raised about their actual safety. This review aims to provide a comprehensive analysis of the last decade literature regarding the concentrations of elutable substances released from dental resin-based materials in different type of solvents. Materials and methods All the literature published on dental journals between January 2010 and April 2022 was searched using international databases (PubMed, Scopus, Web of Science). Due to strict inclusion criteria, only 23 papers out of 877 were considered eligible. The concentration of eluted substances related to surface and volume of the sample was analyzed, considering data at 24 h as a reference. The total cumulative release was examined as well. Results The most eluted substances were HEMA, TEGDMA, and BPA, while the less eluted were Bis-GMA and UDMA. Organic solvents caused significantly higher release of substances than water-based ones. A statistically significant inverse correlation between the release of molecules and their molecular mass was observed. A statistically significant positive correlation between the amount of released molecule and the specimen surface area was detected, as well as a weak positive correlation between the release and the specimen volume. Conclusions Type of solvent, molecular mass of eluates, and specimen surface and volume affect substances release from materials. Clinical relevance It could be advisable to rely on materials based on monomers with a reduced elution tendency for clinical procedures.

“…Indeed, the higher quantity of fillers decreases the ratio of resin and the quantity of resin in contact with saliva, reducing of the biodegradation rate, the leaching of unreacted monomers and degradation products (Bandarra et al, 2020;Cândea Ciurea et al, 2019;Finer and Santerre, 2007). It was indeed shown that commercial PICN tends to release no or very few monomers (Barutcigil et al, 2020;Putzeys et al, 2020). Moreover, PICN with their double-network microstructure resulting in a honeycomb polymer-based structure microstructure allows enhanced bonding properties compared to composite blocks with dispersed fillers microstructure (Eldafrawy et al, 2019;M Eldafrawy et al, 2018).…”

“…Previous studies reported that PICN present better mechanical properties such as fracture toughness and flexural strength than conventional composites (M. Eldafrawy et al, 2018;Nguyen et al, 2014) and good biocompatibility (Barutcigil et al, 2020;Grenade et al, 2017;Tassin et al, 2016) because of the higher filler volume fraction (V f ) and their interpenetrating network technology (Coldea et al, 2013;He et al, 2011;Mainjot et al, 2016;Swain et al, 2016).…”

“…Indeed, conventional photopolymerization results in low DC (55-69%) (Al-Ahdal et al, 2015;Ferracane, 2011;Germscheid et al, 2018;Par et al, 2020). As DC is related to mechanical properties and monomer release, low DC results in poor mechanical properties (Ferracane, 2013), and biological risks because of the release of monomers in oral environment (Barutcigil et al, 2020;Bouillaguet, 2004). Polymerization under high temperature high pressure was shown to solve this issue by significantly increasing crosslinking, DC (up to 96% with an optimum at 200 MPa) (Phan et al, 2015), mechanical properties of Using a too high pressure of polymerization would hence have no benefit due to higher costs, stress and damage on autoclave.…”

This study aimed at determining an optimum polymerization pressure for Polymer Infiltrated Ceramic Network (PICN) blocks by characterizing the conversion degree (DC) and the viscoelastic properties of experimental PICN blocks polymerized at 90 • C under various high pressures followed or not by post-cure treatment (PC). Near infrared analysis and dynamic mechanical analysis were used to characterize DC and viscoelastic properties of sixteen PICN: one control (thermo-cured) and fifteen experimental groups (one thermo-cured followed by PC and fourteen high pressure polymerized PICN, in the range of 50-350 MPa without and with PC). Conversion degree of high pressure polymerized PICN blocks without post curing displays an optimum between 100 and 150 MPa resulting in an improved E ′ and T g . Post curing induces a higher DC with a controversial effect on thermomechanical properties. The results suggested that 100-150 MPa without PC is an optimum polymerization parameter, resulting in PICN blocks with significantly better DC, T g , E'.
