Sažetak
Aim To evaluate the dye leakage of three flowables with a new "three dimensional" method. Methods Three groups of twelve premolars have received Class V cavities of uniform standardized dimensions. The cavities were restored with: Clearfil liner Bond 2 with adhesive SE Bond (group I), Definite flow with Etch & Prime 3.0 (group II) and, the Tetric flow with Syntac Single Component (group III). The teeth were immersed in a contrast dye for 24 hours, rinsed and immersed in the 5% nitric acid for 72 hours. The teeth were acid-softened and the fillings were pulled out of their cavities. The inner surfaces of extracted fillings were photographed in three different rotated positions (3 x 120 o). The photographs were transferred to a computer image and the deepest point and the area of the leaked surface were determined. Results All restorative systems showed leakage at the adhesive level. The statistical analysis showed significant differences between group I and group III in the number of leaked samples, in the depth of leakage and in the leaked surface. Best results in all three ways of leakage evaluation were obtained in group I (Clearfil liner Bond 2 with adhesive SE Bond).
