Sažetak


Uvod/Cilj. Radiokontrastnost jednog endodontskog materijala može znatno varirati u zavisnosti od toga da li je određivano na filmu ili digitalnim senzorom. Digitalna radiografija pruža mnogobrojne prednosti u odnosu na konvencionalnu radiografiju u svakodnevnoj stomatološkoj kliničkoj praksi, kako u pogledu dijagnostičkih mogućnosti, tako i u praćenju rezultata lečenja. Cilj ove studije bio je da se ispitaju mogućnost i konvencionalne i charge-conpled device (CCD) digitalne radiografije za vizualizaciju materijala na radiogramu u zavisnosti od kontrastnog sredstva prisutnog u materijalu. Metode. Eksperimentalni cementi su pripremljeni dodavanjem sledećih kontrastnih sredstava u Portland cement: cink-oksid (ZnO), cirkonijum-oksid (ZrO2), titanijum-dioksid (TiO2), barijum-sulfat (BaSO4), jodoform (CHI3), bizmut-oksid (Bi2O3) i iterbijum-trifluorid (YbF3). Takođe, ispitivano je pet kontrolnih endodontskih cementa: Endomethasone®, Diaket®, N2®, Roth 801® i Acroseal®. Po tri uzorka svakog materijala su radiografisana pored aluminijumskog stepeničastog etalona na filmu (Eastman Kodak Company, Rochester, NY) i CCD digitalnom senzoru (Trophy Radiologie, Cedex, France). Vrednosti rendgenkontrastnosti izračunavane su konverzijom radiografskih gustina uzoraka izraženih optičkim gustinama ili stepenom tona sivo-bele skale u odgovarajuću debljinu aluminijuma. Rezultati. Dvostrukom analizom varijanse nije ustanovljena statistički značajna razlika između primenjenih metoda radiografisanja (p > 0.05), ali su vrsta kontrastnog sredstva (p < 0.001) i interakcija ova dva faktora (p < 0.05) bili značajno različiti. Upareni t-test pokazao je statistički značajnu razliku između korišćenih metoda za čisti Portland cement, sve koncentracije BaSO4 i CHI3, 10% i 20% dodatka ZrO2 i Bi2O3 i 10% i 30% dodatka YbF3 (p < 0.05). Zaključak. Očekuje se da materijali koji sadrže CHI3 ili BaSO4 kao kontrastna sredstva budu lakše uočljivi na digitalnom senzoru nego na konvencionalnom dentalnom filmu. U kliničkom radu mora se imati u vidu kvalitet procene kontrasta koju pokazuje digitalna slika u odnosu na sliku dobijenu konvencionalnom radiografijom.
