Sažetak
Uvod Cementi na bazi kalcijum-silikata danas su najčešće korišćeni materijali u brojnim endodontskim indikacijama zahvaljujući, pre svega, njihovim izuzetnim biološkim i odgovarajućim fizičkim svojstvima. Cilj ovog radaje bio da se proveri rastvorljivost i poroznost eksperimentalnog nanostrukturnog kalcijumsilikatnog cementa. Materijal i metode rada Kao materijal u istraživanju korišćeni su novosintetisani nanostrukturni kalcijumsilikatni (CS) cement, komercijalni kalcijumsilikatni cement (Biodentin), konvencionalni glasjonomer-cement (GJC) Micron Superior i glasjonomer-cement ojačan smolom Fuji VIII. Svi materijali su nakon pripreme postavljeni u metalne prstenove promera 16x2 mm i čuvani u inkubatoru na 37°C tokom 24 sata, a zatim izmereni. Materijali su potom stavljeni u plastične kontejnere sa 25 ml vode i posle 24 časa posušeni, ponovo izmereni, a potom su utvrđivane apsorpcija i rastvorljivost. Rezultati Dobijeni rezultati su ukazali na najveću rastvorljivost kod novosintetisanog CS cementa (12,45), potom kod konvencionalnog GJC Micron Superior (11,5), nešto manju kod Biodentina (6,1) a najmanju kod GJC ojačanog smolom Fuji VIII (3,8). Ove razlike su bile statistički značajne (p<0,005). Najveća apsorpcija je takođe uočena kod CS cementa (24,15), zatim kod Biodentina (18,5) i GJC Micron Superior (17,95), a najmanja kod GJC Fuji VIII (7,75). I ove razlike su bile statistički značajne, osim između GJC Micron Superior i Biodentina. Zaključak Rastvorljivost i poroznost novosintetisanog nanostrukturnog kalcijumsilikatnog cementa je bila značajno veca u poređenju s komercijalnim cementom na bazi kalcijum-silikata, konvencionalnim GJC i GJC ojačanim smolom.
