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,

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.

A Comparative study to quantify the area of obturating material, sealer and voids in root canals obturated with Resilon/Epiphany and gutta-percha with different sealers

Nepal Journal of Medical Sciences, 2014
Background: Complete obturation of the root canal with an inert filling material and creation of a fluid-tight seal are among the major goals of successful endodontic treatment. Methods: Extracted mandibular premolar teeth were decoronated, prepared in a crown-down fashion and irrigated with 2.5% sodium hypochlorite and 17% EDTA.
