Synthesis and characterization of a novel N-vinylcaprolactam-containing acrylic acid terpolymer for applications in glass-ionomer dental cements

Physicomechanical properties of a zinc-reinforced glass ionomer restorative material

“…The relative high fracture toughness of CFR could be due to formation of zinc-polycarboxylate complexes during the setting reaction (6). Additionally, the incorporation of itaconic acid as a comonomer in CFR might increase the flexural and tensile strength of GIC (28). Another explanation for the relative high fracture toughness of CFR is its small mean particle size as compared with other conventional GICs (11).…”

Effects of incorporation of nano-fluorapatite particles on microhardness, fluoride releasing properties, and biocompatibility of a conventional glass ionomer cement (GIC)

“…However, GICs suffer from low mechanical properties, brittleness, unfavorable appearance, and moisture sensitivity in the early stages of the placement. These disadvantages prevent broader clinical applications of GICs, as they are not as durable as resin composites in everyday dentistry [2][3][4][5][6][7][8] . Although stronger GICs with tooth-like appearance and improved handling characteristics are now available, lack of strength and toughness are still major problems [4][5][6][7][8] .…”

“…Glass ionomer cement (GIC) was invented in early 1970's 1) , a water-based cement known as polyalkenoate cement, possessing unique properties such as fluoride release (anti-cariogenic action), adhesion to tooth structure and base metals, and desirable coefficient of thermal expansion, and biocompatibility [2][3][4] . However, GICs suffer from low mechanical properties, brittleness, unfavorable appearance, and moisture sensitivity in the early stages of the placement.…”

Characterization of the calcium-fluoroaluminosilicate glass prepared by a non-hydrolytic sol-gel route for future dental application as glass ionomer cement

“…The glass ionomer consists in an aluminum and silicon matrix comprising an amorphous structure 2 , which renders glass ionomer cements their special mechanical strength properties (compressive, diametral tensile, and biaxial flexural strength) 4 . Nowadays, cement formulations allow for their application as base or dentine substitute under a composite resin, luting cement in crown and bridgework, lining cement under a metal restoration, long-term sealant over an active carious lesion, and restoration material in its own right 5,6 . The commercial glass powder is prepared by melting SiO 2 , Al 2 O 3 , AlF 3 , CaF 2 , NaF, and AlPO 4 at temperatures ranging from 1,200 to 1,550 °C.…”

“…Figure 8 presents the excitation spectrum of the Eu 3+ ion in the sample treated at 1,000 °C. The line observed in this spectrum can be assigned to the transition between the 7 F 0 and the 5 Figure 9 depicts the emission spectra of the Eu 3+ ion recorded in the 550-720 nm range for the sample treated at 1,000 °C and excited at 394 and 462 nm.…”
