Popis:	Svrha rada: Ovo istraživanje in vitro uspoređuje otpuštanje fluora iz mikrolaminiranog staklenog ionomera temeljenog na stakleno-hibridnoj tehnologiji premazanog dvama različitim premazima. Materijali i postupci: Ukupno 18 uzoraka podijeljeno je u skupine po šest uzoraka: (1) stakleni ionomer Equia Forte Fil premazan Equia Forte Coatom (Equia + EC), (2) stakleni ionomer Equia Forte Fil premazan GC Fuji Varnishem (Equia + VC) i (3) nepremazani stakleni ionomer Equia Forte (EQUIA kont). Otpuštanje fluora mjereno je fluor-selektivnom elektrodom (ORION EA 940) nakon 24 sata, 4 dana, 30 dana i 64 dana. ANOVA, Tukeyjev test multiplih usporedbi i paired t-test korišteni su u testiranju razlika među skupinama. Rezultati: Statistički značajne bile su razlike među skupinama i četirima točkama u vremenu (ANOVA, p < 0,0001). Kumulativno otpuštanje iona fluora nakon 64 dana bilo je redom 66,01 mg/l, 123,54 mg/l i 203,22 mg/l za EQUIA + EC, EQUIA + VC i EQUIA kont. Sve su razlike bile statistički značajno različite, osim one između EQUIA + VC i EQUIA kont. nakon 24 sata. Zaključci: Količina otpuštenog fluora bila je značajno manja u uzorcima premazanima nanopunjenim premazom u usporedbi s onima premazanima varnishem i bez premaza. Objective: This in vitro study compares the fluoride release from microlaminated glass ionomer based on glass hybrid technology coated with two different surface coating agents. Materials and Methods: A total of 18 samples were divided into three groups of six samples each: (1) glass ionomer Equia Forte Fil coated with Equia Forte Coat (Equia+EC), (2) glass ionomer Equia Forte Fil coated with GC Fuji Varnish (Equia+VC) and (3) uncoated glass ionomer Equia Forte (EQUIA cont). Fluoride release was measured using an ion-selective electrode (ORION EA 940) after 24 hours, 4 days, 30 days and 64 days. Repeated measures ANOVA, multiple comparisons, Tukey’s test and paired t-test were used to test the differences between the groups. Results: The differences between the groups and four time points were statistically significant (ANOVA, p
