| Popis: | Aim To evaluate the dye leakage of three flowables with a new‘’three dimensional’’ method.Methods Three groups of twelve premolars have received ClassV cavities of uniform standardized dimensions. The cavities wererestored with: Clearfil liner Bond 2 with adhesive SE Bond (groupI), Definite flow with Etch & Prime 3.0 (group II) and, the Tetricflow with Syntac Single Component (group III). The teeth wereimmersed in a contrast dye for 24 hours, rinsed and immersed inthe 5% nitric acid for 72 hours. The teeth were acid-softened andthe fillings were pulled out of their cavities. The inner surfaces ofextracted fillings were photographed in three different rotated positions(3 x 120 o). The photographs were transferred to a computerimage and the deepest point and the area of the leaked surfacewere determined.Results All restorative systems showed leakage at the adhesivelevel. The statistical analysis showed significant differences betweengroup I and group III in the number of leaked samples, inthe depth of leakage and in the leaked surface. Best results in allthree ways of leakage evaluation were obtained in group I (Clearfilliner Bond 2 with adhesive SE Bond).Conclusion In this study, flowable Clearfil liner Bond 2 with adhesiveSE Bond had leaked in all three ways of evaluation significantllyless than Tetric flow in combination with Syntac SingleComponent. |
