“…The concentration (0.15–0.5 wt.%) did not alter the viscosity and did not negatively affect the degree of conversion. This is in agreement with a previous study [ 63 ]. It is important to consider the concentration of the fillers in dental adhesives.…”

This study aimed to evaluate the incorporation of zirconia/silver phosphate nanoparticles to develop experimental dental adhesives and to measure their physical and mechanical properties. The nanoparticles were synthesized by the sonication method, and the phase purity, morphological pattern, and antibacterial properties with Staphylococcus aureus and Pseudomonas aeruginosa were assessed. The silanized nanoparticles were incorporated (0, 0.15, 0.25, and 0.5 wt.%) into the photoactivated dimethacrylate resins. The degree of conversion (DC) was assessed, followed by the micro-hardness and flexural strength/modulus test. Long-term color stability was investigated. The bond strength with the dentin surface was conducted on days 1 and 30. The transmission electron microscopy and X-ray diffractogram confirmed the nano-structure and phase purity of the particles. The nanoparticles showed antibacterial activities against both strains and inhibited biofilm formation. The DC range of the experimental groups was 55–66%. The micro-hardness and flexural strength increased with the concentration of nanoparticles in the resin. The 0.5 wt.% group showed significantly high micro-hardness values, whereas a non-significant difference was observed between the experimental groups for flexural strength. The bond strength was higher on day 1 than on day 30, and a significant difference was observed between the two periods. At day 30, the 0.5 wt.% showed significantly higher values compared to other groups. Long-term color stability was observed for all the samples. The experimental adhesives showed promising results and potential to be used for clinical applications. However, further investigations such as antibacterial, penetration depth, and cytocompatibility are required.

“…Thus, the incorporation of POSS particles improves the hydrophilic stability of adhesives, leading to a higher aging resistance [ 4 ]. Furthermore, MA-POSS-8 is supposed to prevent bond strength degradation over time due to its mineralizing capacity [ 6 , 22 ]. Nonetheless, there are only a few studies that investigated the influence of aging on POSS particles [ 4 , 23 ].…”

This study analyzed the dentin shear bond strength (SBS) of an etch-and-rinse (ER) or a self-etch (SE) adhesive incorporated with multifunctional polyhedral oligomeric silsesquioxanes (MA-POSS-8). An ER adhesive (Solobond Plus, VOCO GmbH, Cuxhaven, Germany) and a universal adhesive applied in SE mode (Scotchbond Universal, 3M, St. Paul, MN, USA) were infiltrated with MA-POSS-8 (Hybrid Plastics Inc., Hattiesburg, MS, USA) at 5 wt.% or 10 wt.%. Pure adhesives served as controls. Bovine dentin specimens were conditioned with one of the adhesives prior to the application of a nano-hybrid composite (Venus Diamond A3, Kulzer, Hanau, Germany). SBS and failure modes were determined after water storage for 24 h, 6 months, 12 months, or 24 months (each subgroup n = 20). Statistical analysis was performed using ANOVAs, Weibull statistics, and χ2 tests (p < 0.05). SBSs for the control groups after 24 h were 17.4 ± 4.9 MPa for the ER adhesive and 19.1 ± 5.2 MPa for the universal adhesive. After 24 months, the SBS of the ER adhesive was significantly higher for 5 wt.% MA-POSS-8 (17.9 ± 5.1 MPa) than for the control group (14.6 ± 3.6 MPa) and 10 wt.% MA-POSS-8 (12.8 ± 4.1 MPa), and more cohesive failures were observed. The SBS of the universal adhesive increased during aging, irrespective of the MA-POSS-8 concentration. 5 wt.% MA-POSS-8 improves the SBS of the ER adhesive and does not impair the SBS of the SE adhesive.

“…Es importante señalar que la acción antibacteriana de las NPs Ag es altamente dependiente del tamaño de la partícula. Estas nanopartículas deben de ser lo suficientemente pequeñas para penetrar la membrana celular y con ello afectar la homeostasis intracelular, y también podrían penetrar al interior de la bacteria (10).…”

Los sistemas adhesivos se utilizan en la práctica clínica diaria; sin embargo, su principal desventaja es la contracción por polimerización que podría ocasionar la aparición de microfiltraciones, acumulo de placa, caries secundaria e hipersensibilidad. Por este motivo, se han venido incorporando agentes antimicrobianos, como el metacrilato de amonio cuaternario fotopolimerizable, los rellenos de vidrio que liberan iones de flúor, el pirogalol y las nanopartículas de plata, calcio y grafeno fluorado. En los últimos años, algunos de estos han demostrado tener una buena efectividad antimicrobiana, que, a su vez, no interfieren con la adhesión en las restauraciones. De tal manera, estos sistemas adhesivos antimicrobianos podrían favorecer a obtener mejores resultados a largo plazo. Las nanopartículas que presentaron mejores resultados fueron el fosfato de calcio amorfo y las compuestas de plata.
