Comparing Coronal Discoloration Between AH26 and ZOE Sealers. [PDF]

Iranian endodontic journal, 2011
Intrinsic tooth discolorations after endodontic treatment are principally attributed to the composition of necrotic pulp tissue, hemorrhage within the pulp cavity, endodontic medicaments and/or filling materials. Residual sealer left in pulp chamber after obturation can cause discoloration.

Evaluation of the apical microleakage of MTA Fillapex, AH26, and Endofill sealers [PDF]

Brazilian Dental Science, 2020
Objective: Proper apical seal plays an important role in the success of root canal treatment. The most common cause of failure of root canal therapy is known as the lack of adequate apical seal. The aim of this in vitro study was to compare the apical microleakage of MTA Fillapex, , and Endofill sealers using dye penetration method.

Electrochemical Evaluation on Apical Leakage of AH26 Sealer after Smear Layer Removal.

Iranian endodontic journal, 2008
Recently, attention has been drawn to the influence of smear layer removal on apical seal, and the relation of root canal filling material with canal wall surface in the presence and absence of the smear layer. The purpose of this study was to evaluate the influence of the smear layer removal on the apical sealing ability of AH26 sealer.Forty extracted

Antibacterial efficacy of AH Plus and AH26 sealers mixed with amoxicillin, triple antibiotic paste and nanosilver [PDF]

Journal of Dental Research, Dental Clinics, Dental Prospects, 2016
Background. Elimination of bacteria from the root canal system is one of the aims of endodontic treatment; hence the incorporation of antibiotics into sealers can increase their antimicrobial efficacy. The aim of the present study was to determine the in vitro antimicrobial effects of AH26 and AH Plus sealers mixed with amoxicillin, triple antibiotic ...

The Effect of Three Different Root Canal Irrigant Protocols for Removing Smear Layer on the Apical Microleakage of AH26 Sealer. [PDF]

Iranian endodontic journal, 2009
The purpose of this in vitro study was to assess the apical microleakage of AH26 sealer when three different root canal irrigant regimens were used.Eighty single-rooted human teeth were randomly divided into three experimental (n=20) and two control groups (n=10).

A comparative evaluation of apical microleakage of MTA fillapex and AH26 sealers in the presence of blood in the canal space of the teeth [PDF]

Caspian journal of dental research, 2014
Introduction: Apical seal in blood or dry root canal is a problem in endodontic treatment. Failure of apical seal causes inflammatory reaction and failure root canal treatment. Because of the sealer properties, root canal should be dry for obturation.

Epoxy resin-based sealers modified with clay nanoparticles: Evaluation of their physicochemical and mechanical properties. [PDF]

Eur J Oral Sci
Abstract Epoxy resin‐based sealers are commonly used in endodontic treatment due to their superior physicochemical properties. Therefore, it is important to utilize these materials by enhancing their properties. Nonetheless, several of their properties remain suboptimal, including the relatively prolonged setting time, the moderate yet clinically ...
