Ključne reči: meki akrilati; potencijalno toksične supstance; HPLC
Sažetak
Uvod: Meki akrilati pripadaju grupi hladno polimerizovanih materijala koji se aplikuju na bazalnu površinu zubne proteze kako bi se eliminisale mehaničke iritacije, omogućilo ozdravljenje oštećene ili inflamirane sluzokože ili se oralno tkivo pripremilo (kondicioniralo) za prihvatanje nove nadoknade. Cilj istraživanja bio je ispitivanje ritma oslobađanja komponenti mekih akrilata u tri različita modela veštačke pljuvačke, u toku tridesetodnevnog opservacionog perioda. Materijal i metode: U ispitivanju su korišćena dva meka akrilata:poli (etil metakrilat)/ n-butil metakrilat i poli (etil metakrilat) / metil metakrilat, koji su odlagani u tri različita modela veštačke pljuvačke, u okviru tri opservaciona perioda: jedan, sedam i trideset dana. Ispitivanje je obuhvatilo detekciju metil metakrilata, etil metakrilata, butil metakrilata, di butil ftalata i benzoil peroksida tečnom hromatografijom pod visokim pritiskom. Rezultati: Količina oslobođenih komponenti srazmerno se povećava sa porastom trajanja opservacionog perioda, bez obzira na model veštačke pljuvačke.Najviše vrednosti svih ispitivanih parametara uočene su nakon tridesetodnevnog opservacionog perioda. Model veštačke pljuvačke nije uticao na ritam oslobađanja komponenti, što znači da se one nesmetano oslobađaju u usnu duplju bez obzira na sastav pljuvačke pacijenta. Zaključak: Sa porastom dužine opservacionog perioda došlo je i do očvršavanja materijala, čime se završava njihova upotrebna vrednost.
