The Tubular Penetration Depth and Adaption of Four Sealers: A Scanning Electron Microscopic Study

BioMed Research International, Volume 2017, Issue 1, 2017., 2017
Background. The tubular penetration and adaptation of the sealer are important factors for successful root canal filling. The aim of this study was to evaluate the tubular penetration depth of four different sealers in the coronal, middle, and apical third of root canals as well as the adaptation of these sealers to root canal walls.

An In Vitro Comparative Study of the Adaptation and Sealing Ability of Two Carrier‐Based Root Canal Obturators

The Scientific World Journal, Volume 2013, Issue 1, 2013., 2013
The study was done to assess the sealing ability and adaptation of RealSeal 1, and to compare it with Thermafil. 65 single‐rooted extracted teeth were selected and root canal treatment was performed. Root canals were obturated with RealSeal 1 or Thermafil. A double chamber bacterial leakage model using E.

Fracture Resistance of Root Canals Obturated with Gutta-Percha versus Resilon with Two Different Techniques. [PDF]

, 2013
Introduction: Dentin removal during root canal instrumentation creates a weaker root structure and increases its potential to fracture. The aim of this in vitro experimental study was to compare fracture resistance of teeth filled with gutta-percha, and ...

Comparison of the tissue biocompatibility of Resilon and gutta-percha cones

Scientific Research and Essays, 2012
The aim of this study was to evaluate the tissue biocompatibility of Resilon compared to gutta-percha cones. Three subcutaneous pockets were made in the back of 36 rats weighing between 200 to 250g. Subcutaneous pockets were left unfilled (control, 1 pocket) or filled with Resilon (1 pocket) or gutta-percha (1 pocket).

In Vitro Effects of External Pressure Changes on the Sealing Ability under Simulated Diving Conditions

International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
Aim. To measure and validate the permeability of pressure changes in correlation to different root filling techniques. Methods. Eighty extracted single‐rooted teeth were randomly assigned to one of eight groups of ten teeth. Following standardized instrumentation and irrigation, root canal fillings were performed using either cold lateral condensation,

Removal of Gutta‐Percha/Zinc‐Oxide‐Eugenol Sealer or Gutta‐Percha/Epoxy Resin Sealer from Severely Curved Canals: An In Vitro Study

International Journal of Dentistry, Volume 2011, Issue 1, 2011., 2011
The aim of this study was to compare the cleanliness of root canal walls after retreatment using two rotary retreatment files to hand instruments in severely curved canals obturated with gutta‐percha and two different sealers. Single rooted mandibular premolars (n = 90) with root curvatures were instrumented and obturated with gutta‐percha and an epoxy

Restoration of Endodontically Treated Teeth Review and Treatment Recommendations

International Journal of Dentistry, Volume 2009, Issue 1, 2009., 2009
Coronal restorations and posts can positively influence the long‐term prognosis of teeth following root canal therapy. Final sealing the canal by placing an appropriate post and core will minimize leakage of oral fluids and bacteria into the periradicular area and is recommended as soon as possible after completion of root canal filling.
