Residual Endodontic Filling Material after Post Space Preparation: A Confocal Microscopic Study
This laboratory study assessed removability of endodontic alkaline cements and resin sealers using coronal cross-sectional slices of roots with single canals. Materials were labelled with 0.1% (w/w) sodium fluorescein prior to mixing so that confocal microscopy could be used to quantify material remaining on the walls of post spaces, to assess cleanliness. Roots of extracted teeth were prepared...
متن کاملComparison between Fiberglass Post Retention and Strength in Immediate and Delayed Preparation of Post-space after Endodontic Treatment
Abstract Objective: Endodontically treated teeth with inadequate crown structure need a radicular post to help restore the tooth to proper function. Therefore, finding an efficient and timely method for preparing the post space in a way that causes less change in the amount of apical flood of the canal, has been the subject of various discussions and researches for many years. In this study, ...
متن کاملEvaluation of sealing ability of three materials used as barriers over the remaining filling material after post space preparation.
The filling material remaining after post space preparation may not be enough to prevent the contamination of periapical tissues when the root canal is exposed to saliva. Thus, the purpose of this study was to evaluate leakage through three different materials used as barriers over the remaining filling. Thirty-two human premolars were selected for this study. Following the endodontic treatment...
متن کاملHealing process of dog teeth after post space preparation and exposition of the filling material to the oral environment.
The purpose of this study was to observe the influence of coronal leakage on the behavior of periapical tissues after root canal filling and post space preparation. Forty root canals of dogs' teeth were instrumented and filled by the lateral condensation technique with gutta percha points and the cements Sealer 26 and Roth. After post space preparation, the remaining filling material was either...
متن کاملFilling Effectiveness and Dentinal Penetration of Endodontic Sealers: A Stereo and Confocal Laser Scanning Microscopy Study.
The aim of this study was to evaluate the filling effectiveness and dentinal penetration of the sealers AH Plus, Pulp Canal Sealer EWT, Sealapex and MTA Fillapex applied according to the vertical condensation technique using thermoplastic gutta-percha. Forty single-rooted teeth were selected. After chemical-mechanical preparation and root-canal filling, sections of the root (2, 4 and 6 mm from ...
