Adresa za dopisivanje Nada Galić Sveučilište u Zagrebu Stomatološki fakultet Zavod za endodonciju i restorativnu stomatologiju Gundulićeva 5, 10 000 Zagreb [email protected] Sažetak Svrha rada bila je ispitati genotoksično djelovanje pet dentinskih adheziva: Adper Single Bonda, Adper Single Bonda 2, Prompt L-popa, Excitea i OptiBonda Solo Plus. Ispitivanje genotoksičnosti provedeno je na humanim limfocitima periferne krvi u uvjetima in vitro, ispitane koncentracije adheziva bile su 0,2, 0,5 i 5 μg/ml, a testirana vremena eluacije 1 sat, 24 sata i 5 dana. Genotoksičnost adheziva ispitivala se citogenetičkom metodom analizom strukturnih aberacija kromosoma, dakle, određivanjem ukupnog broja kromosomskih lomova, kromatidnih lomova i acentričnih fragmenata. Rezultati pokazuju genotoksičnost OptiBonda Solo Plus već u koncentraciji 0,2 μg/ml i to nakon 24-satne eluacije, zatim OptiBonda Solo Plus u koncentraciji 0,5 μg/ml nakon jednosatne eluacije, OptiBonda Solo Plus, Adper Single Bonda 2 i Excitea u koncentraciji 0,5 μg/ml nakon jednodnevne eluacije. U koncentraciji 5 μg/ml nakon jednosatne eluacije genotoksičnost su pokazali OptiBond Solo Plus, Excite, Adper Single Bond 2 i Adper Single Bond, a nakon jednodnevne eluacije svi su ispitivani adhezivi pokazali genotoksičnost. Iz rezultata je jasno da genotoksičnost raste s porastom koncentracije adheziva, a smanjuje se s vremenom. Najveća genotoksičnost zabilježena je nakon 24-satne eluacije.
