Leakage of five root canal sealers

International Endodontic Journal, 1999
Aim The aim of this study was to examine the apical sealing ability of five root canal sealers using a fluid transport model.Methodology A comparison of root canal sealers AH26, AH Plus, Diaket, Apexit, and Ketac‐Endo were tested on 60 single‐rooted teeth.

pH Measurement of root canal sealers

Journal of Endodontics, 1998
The purpose of this study was to compare the surface pH level of three different type sealers after mixing at various time intervals in vitro. The cements were mixed according to the manufacturer's instructions. They were incubated to set in 100% humidity at 37 degrees C for 1 h, 24 h, 5 days, 8 days, 2 wk, 3 wk, 4 wk, 5 wk, and 7 wk. pH was calculated

MTA-Based Root Canal Sealers

Journal of Orofacial Research, 2013
Mineral trioxide aggregate (MTA) has been recommended for pulp capping, pulpotomy, apical barrier formation in teeth with open apexes, repair of root perforation and root canal obturation. Since, its introduction in 1993 by Torabinejad numerous studies have been published regarding various aspects of this material.

Glass Ionomer Root Canal Sealers

Journal of Veterinary Dentistry, 1993
Since their introduction, glassionomer cements have undergone changes in formulations and have been endorsed for a number of clinical applications. Consistent reporting of bio-compatibility, durable adhesion, and beneficial fluoride release have followed the evolving glass ionomer cement. This report recommends the use of glass ionomer cements as root

Interface of dentine to root canal sealers

Journal of Dentistry, 2014
Root canal sealers can interact physically or chemically with dentine. The aim of this study was to characterize the dentine-root canal sealer interface of experimental sealers based on Portland cement using an epoxy-based vehicle in comparison to an epoxy resin sealer, AH Plus.Root canals were biomechanically prepared and filled with any one of the ...

A new glass ionomer root canal sealer

Journal of Endodontics, 1991
Various physical characteristics of a new glass ionomer root canal sealer were tested. These included setting time, ease of delivery to the root canal, adaptability and adhesion to the dentinal wall of the root canal, and radiopacity. Scanning electron micrographs and electron microprobe analyses were made.

In vitro genotoxicity of root canal sealers

International Endodontic Journal, 2009
AbstractAim  To evaluate the effect of leakage on differences in genotoxicity of root canal sealers ex vivo according to their main components using two different cytogenetic assays.Methodology  Six materials of different composition (GuttaFlow, Epiphany, Diaket, IRM, SuperEBA and Hermetic) were tested on human peripheral blood lymphocytes using the ...

Isopropyl cyanoacrylate as a root canal sealer

Journal of Endodontics, 1984
Isopropyl cyanocacrylate was evaluated as a root canl sealer by comparing it with three commercial sealers. Six groups of 20 teeth were studied: a negative control group in which apical openings were plugged with wax; a positive control group in which canals were filled with gutta-percha without any sealer; and four experimental groups in which the ...

Physical Properties of 5 Root Canal Sealers

Journal of Endodontics, 2013
The aim of this study was to evaluate the pH change, viscosity and other physical properties of 2 novel root canal sealers (MTA Fillapex and Endosequence BC) in comparison with 2 epoxy resin-based sealers (AH Plus and ThermaSeal), a silicone-based sealer (GuttaFlow), and a zinc oxide-eugenol-based sealer (Pulp Canal Sealer).ISO 6876/2001 specifications

Cytotoxicity evaluation of six root canal sealers

Journal of Endodontics, 1995
Cell cultures of human gingival fibroblasts obtained from healthy patients were used to evaluate the toxicity of six different endodontic cements: AH-26, Pulp Canal Sealer, Rocanal-R2, Rocanal-R3, Bioseal, and Endomethasone. The toxicity was determined by measuring spectrophotometrically at 405 nm the colorimetric reaction of N-acetyl-beta ...
