Identification of culturable and non-culturable microorganisms, lipopolysaccharides and lipoteichoic acids from root canals of teeth with endodontic failure.

Journal of Endodontics, 2021
AIM To elucidate the presence of apical periodontitis in the root canal of teeth with secondary/persistent infection, including composition of microbiota, levels of endotoxins and lipoteichoic acid, and clinical implications of these findings.

Direct bilayered biomimetic composite restoration: The effect of a cusp-supporting short fiber-reinforced base design on the chewing fracture resistance and failure mode of molars with or without endodontic treatment.

Journal of The Mechanical Behavior of Biomedical Materials, 2020
The aim of this study was to assess the chewing fracture resistance of compromised molars restored with direct composite resin (CR) restorations, with and without a short-fiber reinforcing (short-FRC) base.

Torsional failure of endodontic files

Journal of Endodontics, 1976
The effects of some hitherto ignored clinical variables on the torsional properties of endodontic files were determined. Torsional tests and scanning electron microscope examination revealed that endodontic files twisted in a counterclockwise manner were extremely brittle in comparison to those twisted in a clockwise manner.

Nonsurgical retreatment of a postsurgical endodontic failure.

Journal of Endodontics, 1984
A 45-yr-old Caucasian woman was referred by her family dentist because of pain and periapical pathology associated with both her maxillary central incisors. The teeth had been endodontically treated and retrofill amalgams had been placed. Both teeth were diagnosed as postsurgical endodontic failures. The teeth were retreated nonsurgically.

Clinical and Radiographic Failure of Non-surgical Endodontic Treatment and Retreatment Using Single-cone Technique with Calcium Silicate-Based Sealers: A Systematic Review and Meta-Analysis.

Journal of Endodontics
INTRODUCTION This systematic review and meta-analysis aimed to evaluate the clinical and radiographic failure of non-surgical endodontic treatment and retreatment for mature permanent teeth with or without apical periodontitis using the single-cone (SC ...

Treatment outcome of surgical and non-surgical endodontic retreatment of teeth with apical periodontitis.

International Endodontic Journal, 2023
AIMS To evaluate and compare the treatment outcome of root-filled teeth with apical periodontitis treated either non-surgically or by endodontic microsurgery, and to assess the influence of an intra-radicular post, clinical and demographic factors ...

Extreme resistance of Enterococcus faecalis and its role in endodontic treatment failure

Progress in Medical Sciences, 2018
A successful root canal treatment aims at complete elimination of microorganisms from the root canal space, thus preventing chances of reinfection. In spite of the relatively high success rate of endodontic procedures, failures occur.
