Abstract
Konvencionalni SIC su dvokomponentni materijali koji se sastoje od kalcijfluoro-alumosilikatnog staklenog praška i vodene otopine poliakrilne kiseline. Stvrdnjavaju se kemijski, acido – baznom reakcijom. Kod smolom modificiranih SIC u vodenu otopinu poliakrilne kiseline dodan je hidrofilni monomer (HEMA) što im omogućava početno stvrdnjavanje pomoću vidljivog svjetla i štiti matriks cementa od rane apsorpcije vode. Daljnja maturacija odvija se acido – baznom reakcijom. Modificirani SIC pokazuju bolje fizičko – mehaničke osobine u odnosu na konvencionalne cemente, a ujedno je zadržana sposobnost kemijskog svezivanja za mineralizirana zubna tkiva kao i sposobnost otpuštanja fluorida zaslužna za prevenciju sekundarnog karijesa. Biokompatibilnost modificiranog cementa je nešto umanjena zbog prisustva nepolimeriziranog monomera.
Abstract (english)
Conventional GIC are two-component materials, composed of calcium-fluoroaluminosilicate glass powder and an aqueous polyacrilic acid. They are chemically cured through an acid – base reaction. In resin – modified GIC a hydrophilic monomer (HEMA) has been added to the aqueous polyacrlic acid solution. It provides an initial light – curing and therefore protects the cement matrix from an early water – sorption. The curing proceedes by means of an acid – base reaction. Resin – modified GIC have better mechanical features than the traditional ones. They have kept the ability for chemical bonding to mineralised tooth tissues, as well as the ability to release fluoride. Biocompatibility of resin – modified cements has been somewhat reduced due to the presence of an unpolymerised monomer.
