<br/><br/> The aim of the present study was to compare the apical sealing with two procedures fluid filtration and silver dye-penetration methods,48 samples were filled with Activ GP. The fluid filtration and the dye- penetration techniques showed that Active GP displayed apical leakage with different variation at the three periods
