Physicochemical Properties, Sealing Ability, Bond Strength and Cytotoxicity of a New Dimethacrylate-based Root Canal Sealer

Journal of the Formosan Medical Association, 2010
Resin-based root canal sealer can bond to dentin and establish a hermetic seal. The aim of this study was to evaluate the physicochemical properties, sealing ability, cytotoxicity and bond strength of a new resin-based root canal sealer (NRCS).

Intraoperative Use of CBCT for Identification and Localization of Calcified Canals: A Clinical Technique

Case Reports in Dentistry, Volume 2017, Issue 1, 2017., 2017
Localization of calcified canals has always been a challenge in the field of endodontics. The following report of three cases describes a technique for the identification and negotiation of obliterated canals by use of cone beam computed tomography (CBCT) intraoperatively. Canal orifices could not be found clinically in all three cases.

Evaluation of the Sealing Ability of Three Obturation Techniques Using a Glucose Leakage Test

BioMed Research International, Volume 2017, Issue 1, 2017., 2017
The aim of this study was to evaluate the sealing ability of three different canal filling techniques. Sixty‐four roots of extracted human maxillary anterior teeth were prepared using ProTaper® rotary instruments. The specimens were then randomly divided into 3 experimental groups (n = 16) and 2 control groups (n = 8). The root canals were filled using

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.

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.

Coronal and apical leakage analysis of two different root canal obturation systems

Brazilian Oral Research, 2008
This study compared the coronal and apical leakage of AH Plus with gutta-percha to that of Epiphany with Resilon. Twenty-four single rooted teeth were instrumented and divided into 2 groups according to the solutions for smear layer removal and the ...
