Physical Properties of 5 Root Canal Sealers
Journal of Endodontics, 2013The 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

Evaluation of the radiopacity of different root canal sealers
Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2009 The aims of this study were to compare the radiopacity of 8 root canal sealers relative to gutta-percha and dentin in standard discs and to evaluate the effect of these sealers on the radiopacity of root canal fillings in simulated canals.Radiographs were taken of 1-mm-thick specimens of 8 root canal sealers (Diaket, Endion, MTA, Endofil, Roeko Seal ...

[In vitro evaluation of five root canal sealers].
Minerva stomatologica, 2003 An adequate film thickness is an important property of an endodontic sealer, when used in combination with gutta-percha, to eventually fill minimal voids between gutta-percha and the root canal walls, ensuring an hermetic three-dimensional root canal obturation. The goal of the present study was to evaluate the film thickness of the following five root

Radiopacity of root canal sealers
Oral Surgery, Oral Medicine, Oral Pathology, 1981A standardized and reproducible method of radiopacity measurements of dental materials is presented. The method entails densitometric comparison of standard-sized specimens with an aluminum step wedge under controlled conditions for exposure and film processing. Methodologic aspects have been evaluated and discussed.

Allergenic potential of root canal sealers
Dental Traumatology, 1985Abstract The sensitizing potential of 4 root canal sealers, Endo‐methasone, ProcoSol, AH26, and Kloroperka N‐Ø, was evaluated in a modified guinea pig maximization test. All 4 materials induced sensitivity. When single components of the sealers were used in subsequent skin challenges of the same animals, positive responses were elicited by eugenol and ...

Isopropyl cyanoacrylate as a root canal sealer
Journal of Endodontics, 1984Isopropyl 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 ...

pH Measurement of root canal sealers
Journal of Endodontics, 1998The 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

A Novel Polyurethane Expandable Root Canal Sealer
Journal of Endodontics, 2021Endodontic sealers play a vital role in the obturation of root canal space. The aim of this study was to evaluate the utility of a recently developed polyurethane expandable sealer (PES), along with its cytotoxicity and dimensional changes.L929 fibroblasts and an cell viability assay (MTS assay) were used to determine the cytotoxicity of dental sealers
