A comparison evaluation of sealers adhesion to a dentin surfaces of root canals after temporary application of calcium hydroxide

Abstract

In this article results of research on adhesion of two types of root sealer to a surface of root channels after their temporary sealing by preparations of hydroxide of calcium are presented. In research sealers on the basis of epokside pitch and zinc oxide eugenol used. Also calcium hydroxide applications on a water-soluble and oil base used. For the first time the method by determination of adhesive durability is used. Found that the highest values of shear adhesion strength to samples, sealed by eugenol zink oxide paste, suggesting a stronger connection with the surface of the dentine.
