Comparative Resistance of AH26 and a New Sealer Prototype to a Bacterial Challenge

International Journal of Dentistry, 2012
Objective. This study compared the leakage resistance of a New Sealer Prototype (NSP) with a traditional sealer (AH 26) in Resilon-filled roots subjected to a bacterial challenge. Study Design. 41 roots were instrumented to ISO size 50 apically. Group 1 (

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

International Journal of Dentistry, 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).

Apical sealing ability of resilon/epiphany system

Dental Research Journal, 2014
Background: Endodontic leakage research focus mainly on the quality of the apical seal of the root canal system and the newly introduced resilon/epiphany system claim to be superior to Gutta-percha in respect to obturation procedure.

Studying the Effect of Four Postspace Preparation Techniques on the Apical Seal Integrity of the Root Canals Obturated With the Resilon/RealSeal System and the Lateral Condensation Technique. [PDF]

Int J Dent
Objectives: The objective of this study was to investigate the effect of different postspace preparation techniques on the apical seal of Resilon/RealSeal obturation system in root canals filled with the lateral condensation technique. Methods: A total of 92 maxillary central incisors were selected for this study, and their crowns were cut.

Bacterial Leakage Testing in Dentistry: A Comprehensive Review on Methods, Models, and Clinical Relevance. [PDF]

Scientifica (Cairo)
Background The marginal gap increases the rate of bacterial leakage and treatment failure; the measurement of the marginal gap is questionable. The literature revealed that when bacteria get trapped within the smear layer, they can multiply and re‐contaminate the root canal system, leading to treatment failure.

Comparative evaluation of fracture resistance of teeth obturated using three different systems – AH plus/Gutta-percha, Resilon/Realseal self-etch, and Endofill/Gutta-percha: An in vitro study

Journal of Oral Research and Review, 2016
Introduction: Endodontically treated teeth are more prone to fracture under masticatory forces. Resin-based dental materials have been proposed as a means to reinforce an endodontically treated tooth through the use of adhesive sealers in the root canal ...

Factors that affect the outcomes of root canal treatment and retreatment—A reframing of the principles

International Endodontic Journal, Volume 56, Issue S2, Page 82-115, March 2023., 2023
Abstract This paper undertakes a broad and comprehensive synthesis of relevant clinical, biological, biomechanical, technical and healthcare services data to understand the factors affecting outcomes of periapical healing after root canal (re)treatment. The medical and dental evidence‐based era (1980–present) is contextualized with the earlier evidence

The dentine‐sealer interface: Modulation of antimicrobial effects by irrigation

International Endodontic Journal, Volume 55, Issue 5, Page 544-560, May 2022., 2022
Abstract Aim Assess whether sodium hypochlorite (NaOCl) or chlorhexidine (CHX) and two irrigation protocols may alter the antibacterial properties of dentine and three endodontic sealers using a novel ex vivo tooth model. Methodology Prior to antibacterial testing, the tooth model was validated by means of scanning electron microscopy (SEM) to evaluate

Effect of an Intraorifice Barrier on Endodontically Treated Teeth: A Systematic Review and Meta‐Analysis of In Vitro Studies

BioMed Research International, Volume 2022, Issue 1, 2022., 2022
The main cause of unsuccess in endodontically treated teeth (ETT) is due to bacterial recontamination. The placement of an intraorifice barrier (IOB) has been proposed for preventing this event in cases that the restoration is in an inadequate condition, enhancing the possibilities for predictable long‐term success in endodontic therapy. Objectives. To

Root canal filling using Resilon: a review [PDF]

British Dental Journal, 2011
Root canal treatment is achieved by chemo-mechanical debridement of the root canal system followed by filling. The filling material 'entombs' residual bacteria and acts as a barrier which prevents the entrance of oral microorganisms and reinfection of the root canal system through microleakage.
