Leakage along apical root fillings with and without smear layer using two different leakage models: a two‐month longitudinal <i>ex vivo</i> study

Abstract

Under the conditions of this study, the glucose penetration model was more sensitive in detecting leakage along root fillings. Removing the smear layer before filling did not improve the sealing of the apical 4 mm of filling. Resilon allowed more glucose penetration but the same amount of fluid transport as the gutta-percha root fillings.
