Physicochemical and mechanical properties of zirconium oxide and niobium oxide modified Portland cement-based experimental endodontic sealers
(2013-09-02)
Aim: To evaluate the physicochemical and mechanical properties of Portland cement-based experimental sealers (ES) with different radiopacifying agents (zirconium oxide and niobium oxide micro- and nanoparticles) in comparison ...
Setting Time Affects In Vitro Biological Properties of Root Canal Sealers
(2013-09-30)
Introduction: Biocompatibility of root canal sealers is important because of the long-term contact of their eluates and/or degradation products with periapical tissues. The literature still lacks studies about the genotoxic ...
Bacterial leakage in root canals filled with conventional and MTA-based sealers
(Wiley-Blackwell, 2011-04-01)
P>AimTo evaluate bacterial leakage after filling root canals with several endodontic sealers, including MTA-based materials.MethodologyOne hundred and thirty single-rooted extracted human teeth were randomly divided into ...
Evaluation of apical sealing of three endodontic sealers
(2000-01-01)
Aim: The apical sealing ability of three different endodontic sealers was evaluated in extracted teeth using dye penetration. Methodology: The root canals of 99 extracted human maxillary central incisors were prepared ...
Evaluation of the biocompatibility of root canal sealers using subcutaneous implants
(2007-05-01)
The purpose of this study was to evaluate in vivo the biocompatibility of Endométhasone, Pulp Canal Sealer EWT and AHPlus root canal sealers after implantation in rat connective tissue. Twenty-four Wistar-Furth rats were ...
Antibiofilm activity, pH and solubility of endodontic sealers
(2013-08-01)
Aim: To evaluate antibiofilm activity against Enterococcus faecalis, pH and solubility of AH Plus, Sealer 26, Epiphany SE, Sealapex, Activ GP, MTA Fillapex (MTA-F) and an experimental MTA-based Sealer (MTA-S). Methodology: ...
Quantification of fibrosis and mast cells in the tissue response of endodontic sealer irradiated by low-level laser therapy
(Springer London Ltd, 2011-11-01)
Low-level laser therapy (LLLT) accelerates tissue repair. Mast cells induce the proliferation of fibroblasts and the development of local fibrosis. The objective of this study was to quantify fibrosis rate and mast cells ...
pH, Calcium Ion Release, and Setting Time of an Experimental Mineral Trioxide Aggregate-based Root Canal Sealer
(Elsevier B.V., 2011-06-01)
Introduction: An experimental mineral trioxide aggregate sealer (MTAS) has been developed for use as a root canal sealer. The aim of this study was to evaluate the setting time, pH, and calcium ion release of MTAS compared ...
Clinical microscopic analysis of protaper retreatment system efficacy considering root canal thirds using three endodontic sealers
(Wiley-Blackwell, 2012-09-01)
To evaluate the efficacy of ProTaper Universal rotary retreatment system and the influence of sealer type on the presence of filling debris in the reinstrumented canals viewed in an operative clinical microscope. Forty-five ...
Tissue response to an epoxy resin-based root canal sealer
(Munksgaard Int Publ Ltd, 1999-02-01)
The objective of the present study was to evaluate two different types of root canal sealers: AH Plus (an epoxy resin-based sealer) and Fill Canal (a zinc oxide-eugenol based sealer). A total of 34 root canals with vital ...
