In vivo evaluation of the antibacterial efficacy of polyethyleneimine nanoparticle-modified glass ionomer cement versus conventional glass ionomer cement.
AIM Cemented crowns are susceptible to microleakage over time. Incorporation of quaternized polyethyleneimine (QPEI) nanoparticles into glass ionomer cement (GIC) may enhance its antibacterial properties, potentially increasing crown longevity. Insoluble QPEI nanoparticles exhibit strong antibacterial activity against...
