Sažetak
Uvod Kvalitet veze kompozita za tvrda zubna tkiva se najčešće procenjuje jačinom vezivanja ili izostankom marginalne pukotine po obodu restauracija. Marginalni indeks (MI) je važan pokazatelj efikasnosti pripoja materijala za zubna tkiva jer istovremeno pokazuje vrednosti i širine i dužine marginalne pukotine. Cilj rada Cilj rada je bio da se kvantitativno i kvalitativno proceni veza kompozitnih materijala za gleđ i utvrde vrednosti MI u gleđi nakon primene dve tehnike svetlosne polimerizacije i dva kompozitna sistema. Metode rada Na ekstrahovanim zubima je restaurisano 40 kaviteta pete klase za analizu pripoja kompozita za gleđ skening- elektronskom mikroskopijom (SEM). Adhezija za gleđ je obezbeđivana primenom Adper Single Bond 2 - ASB (3M ESPE), odnosno primenom Adper Easy One - AEO (3M ESPE). Svetlosna polimerizacija kompozitnog materijala (Filtek Ultimate - FU; 3M ESPE) vršena je standardnim halogenim svetlom (HIP) ili tzv. soft start programom (SOF). Rezultati Kvantitativna i kvalitativna analiza je pokazala bolje mikromorfološko vezivanje kompozita za gleđ kod SOF osvetljavanja i ASB/FU kompozitnog sistema. Na osnovu dvosmernog ANOVA testa, razlike u vrednosti MI između različitih svetlosnopolimerizujućih tehnika (HIP: 0,6707 i SOF: 0,2395) bile su statistički značajne (p<0,001), kao i razlike između kompozitnih sistema (ASB/FU: 0,0470 i AEO/FU: 0,8651; p<0,001). Zaključak Bolji marginalni pripoj kompozita za gleđ obezbeđen je primenom SOF osvetljavanja kod oba kompozitna sistema.
