Water dynamics in glass ionomer cements

Compressive Strength of New Glass Ionomer Cement Technology based Restorative Materials after Thermocycling and Cyclic Loading

“…The clinically important mechanical property of compressive strength after thermocycling and cyclic loading was not found to be significantly improved by coating glass ionomer based restorative materials with nano-filled resinous coats, although a trend toward increase was recorded in the coated samples. noj vodi, no nije se očekivalo da će to utjecati na upijanje vode nepremazanih uzoraka jer se pokazalo da je gubitak slabo vezane vode u ovoj fazi kritičan, kako je već spomenuto (27).…”

“…The observed increase of CS in the coated samples, although not statistically significant, could be explained by the reduction of undesirable early water exchange (25). The application of a coating on the newly placed GIC was, therefore, recommended to prevent the water escape before it became strongly bound by hydration of the cations released from the glass or siloxane groups on the surface of glass particles (26,27). In the present study the specimens were stored in distilled water before the compressive strength measure-zultat ne može se smatrati proturječnim rezultatima u ovom istraživanju jer je u ovom istraživanju upotrijebljen nanopunjeni svjetlosno-polimerizirajući premaz (coat), a ne jednostavni premaz (varnish).…”

“…Uočeno povećanje CS-a u premazanim uzorcima, premda nije bilo statistički značajno, može se objasniti smanjenjem nepoželjne rane izmjene vode (25). Primjena coata na novopostavljeni GIC stoga se preporučuje kako bi se spriječila dehidracija prije čvrstog vezanja vode hidracijom kationa otpuštenih iz stakla ili siloksanskih skupina na površini staklenih čestica (26,27). U ovom su istraživanju uzorci prije mjerenja kompresijske čvrstoće bili pohranjeni u destilira- ments were taken, but it was not expected that the storage in water would influence the water sorption in the uncoated groups since the escape of loosely bound water was shown to be critical at this stage, as mentioned earlier (27).…”

After the acid-base reaction, clinically described as the initial setting, the maturation process takes place within the material until complete setting occurs (28).…”

Antimicrobial Efficacy of Cinnamon Bark Oil on Lactobacillus acidophilus and its Effect on Compressive Strength of Glass Ionomer Cement

“…For children, these materials have offered an alternative that has insidiously become a "standard of care" in a variety of clinical indications for children. 16 Glass ionomer cement has gained wide acceptance and popularity, mainly due to its ease of handling characteristics, chemical bonding to tooth structure, and fluoride release. 17 However, according to Mazzaoui et al, 18 the amount of fluoride released from GIC is not sufficient to show an antibacterial effect against caries-causing pathogens which can give rise to secondary caries.…”
