Root filling quality and bond strength of endodontic sealers to human and bovine dentin

RFO UPF; 28 (1), 2023
Objetivo: Este estudo teve como objetivo comparar a qualidade da obturação e a resistência de união de dois cimentos endodônticos, AH Plus e Bio-C Sealer, em dentes humanos e bovinos. Métodos: Os canais radiculares de 60 dentes unirradiculares [30 humanos (H) e 30 bovinos (B)] foram preparados e ob...

Effect of sonic and ultrasonic activation on physicochemical properties of root canal sealers

J. appl. oral sci; 27 (), 2019
Abstract Objective: To evaluate the effect of ultrasonic and sonic activation on physicochemical properties of AH Plus, MTA Fillapex, ADSeal, GuttaFlow Bioseal, and GuttaFlow 2 sealers. Methodology: Three experimental groups were formed: no activation (NA), ultrasonic activation (UA), and sonic activat...

Evaluation of the physicochemical properties of silicone- and epoxy resin-based root canal sealers

Abstract To assess the physicochemical properties of AH Plus, GuttaFlow 2, GuttaFlow BioSeal, and MM Seal, five samples of each root canal sealer were evaluated to determine their setting time (ST), dimensional change (DC), solubility (SL), flow (FL), and radiopacity (RD) according to American National S...

Effect of rewetting solutions on micropush-out dentin bond strength of new bioceramic endodontic material

Abstract To evaluate the influence of rewetting solutions on bond strength to root dentin of conventional gutta-percha (GP) or niobium phosphate glass-based gutta-percha (GNb) associated with a bioceramic sealer. The root canals of 80 human mandibular premolars were prepared using nickel-titanium instrum...

In vitro antibacterial activity of a silicone-based endodontic sealer and two conventional sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate whether the modification in the silver component is capable of providing GuttaFlow 2 with antibacterial activity against Enterococcus faecalis compared with epoxy resin-based (AH Plus) and zinc oxide and eugenol-based (Endofill) sealers. The antibacterial ac...

Volume of sealer in the apical region of teeth filled by different techniques: a micro-CT analysis

Braz. oral res. (Online); 30 (1), 2016
Abstract The volume of sealer in the apical 1 mm of teeth filled using different techniques was evaluated by micro-commuted tomography (micro-CT). Sixty-four maxillary central incisors were prepared using NiTi rotary instruments. Teeth were randomly distributed into four groups according to root canal se...

Filling of simulated lateral canals with gutta-percha or thermoplastic polymer by warm vertical compaction

Braz. oral res. (Online); 29 (1), 2015
The aim of this study was to evaluate the ability of gutta-percha and a thermoplastic synthetic polymer (Resilon) to fill simulated lateral canals, using warm vertical compaction. Forty-five single-rooted human teeth were prepared using the rotary crown-down technique. Artificial lateral canals were made...

Effect of endodontic sealer and resin luting strategies on pull-out bond strength of glass fiber posts to dentin

Acta odontol. latinoam; 23 (3), 2010
The aim of this study was to evaluate the influence of eugenolcontaining endodontic sealers and luting strategy on the pull-out bond strength of glass fiber posts to dentin. Sixty-four bovine incisors were randomly assigned into two groups of 32 specimens each for obturation procedure with gutta-percha o...

Descontaminaçäo química de cones de guta-percha por diferentes concentraçöes de NaOCl
Chemical decontamination of gutta-percha cones by different concentrations of NaOCl

Neste experimento foi testada a efetividade de 5 diferentes concentraçöes de hipoclorito de sódio (0,5 percent, 1 percent, 2,5 percent, 4 percent e 5,25 percent) na descontaminaçäo de cones de guta-percha artificialmente contaminados por diferentes tipos de microrganismos. Também foi determinado o ...

Evaluación comparativa de cuatro técnicas de obturación endodóntica
Comparative evaluation of four endodontic obturation techniques

Rev. Círc. Odontol. Ros; 65 (1), 1999
El propósito de la presente experiencia fue evaluar comparativamente la calidad de la obturación de cuatro técnicas de obturación endodóntica: técnica de condensación lateral, técnica híbrida de compactación termomecánica, sistema Thermafil y sistema Obtura II. Se utilizaron 40 caninos que fue...
