Effect of Immediate and Delayed Post Preparation on Apical Microleakage by Using Methacrylate-based EndoREZ Sealer with or without Accelerator

The effect of ferrule on the fracture mode of endodontically treated canines restored with fibre posts and metal-ceramic or all-ceramic crowns

“…The teeth were stored in an incubator (at 37 8C, 100% relative humidity). 35,36 After obturation, each specimen was mounted using autopolymerizing acrylic resin (Triplex; Ivoclar Vivadent, Schaan, Liechtenstein) in a trapezoidal mould perpendicular to the long access of the root with the use of a surveyor (Serveyor Parallometer System, Despley Ceramco, York, USA), to ensure that the path of the embedded canines was perpendicular to the CEJ. To simulate the periodontal ligament, the root surface of each tooth was coated with a layer of polyvinilsiloxane impression material (Virtual; Ivoclar Vivadent, Schaan, Liechtenstein) prior to embedding.…”

The Effect of Time of Post Space Preparation on the Seal and Adaptation of Resilon-Epiphany Se & Gutta-percha-Ah Plus Sealer- An –Sem Study

“…Endodontic treatment is a common step in prosthetic rehabilitation [3] and endodontically treated teeth with insufficient tooth structure generally require radicular posts to assist in restoring the tooth to function [4]. Any failure caused by apical leakage will result into a re-infected tooth making the entire procedure come to a zilch.…”

Effect of Immediate and Delayed Postpreparation on the Integrity of the Apical Seal: An in vitro Study

“…2 During the postspace preparation, encroachment on the apical third of root canal filling may disrupt its integrity of apical seal. [2][3][4] Disruption of seal is the basic problem to be concerned very seriously. Its well documented that according to the hollow tube theory, fluid in the apical part of the canal leads to degradation of this fluid and formation of toxins and induces and maintains periapical inflammation.…”
