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.

Influence of Different Restorative Techniques on the Strength of Endodontically Treated Weakened Roots

International Journal of Dentistry, Volume 2012, Issue 1, 2012., 2012
Objective. Comparing effect of different restoration techniques on fracture resistance of compromised roots. Methods. Crowns of 100 single‐rooted teeth were sectioned and 10 roots were kept as negative control group (Group 1). Remaining roots were instrumented and divided into one and positive control group of 10 samples (Group 2) and 4 experimental ...

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,
