Impact of calcium aluminate cement with additives on dental pulp-derived cells

J. appl. oral sci; 28 (), 2020
Abstract Calcium aluminate cement (CAC) has been highlighted as a promising alternative for endodontic use aiming at periapical tissue repair. However, its effects on dental pulp cells have been poorly explored. Objective: This study assessed the impact of calcium chloride (CaCl2) and bismuth oxide (Bi2O...

Ytterbium oxide as radiopacifier of calcium silicate-based cements. physicochemical and biological properties

Braz. dent. j; 29 (5), 2018
Abstract This study evaluated physicochemical properties, cytotoxicity and bioactivity of MTA Angelus (MTA), calcium silicate-based cement (CSC) and CSC with 30% Ytterbium oxide (CSC/Yb2O3). Setting time was evaluated using Gilmore needles. Compressive strength was evaluated in a mechanical machine. Radi...

Evaluation of physicochemical properties of root-end filling materials using conventional and Micro-CT tests

J. appl. oral sci; 25 (4), 2017
Abstract Objective To evaluate solubility, dimensional stability, filling ability and volumetric change of root-end filling materials using conventional tests and new Micro-CT-based methods. Material and Methods Solubility (loss of mass) after 7 and 30 days, and dimensional stability (in mm) were eva...

Effect of addition of nano-hydroxyapatite on physico-chemical and antibiofilm properties of calcium silicate cements

J. appl. oral sci; 24 (3), 2016
ABSTRACT Objective Mineral Trioxide Aggregate (MTA) is a calcium silicate cement composed of Portland cement (PC) and bismuth oxide. Hydroxyapatite has been incorporated to enhance mechanical and biological properties of dental materials. This study evaluated physicochemical and mechanical properties a...

Push-out bond strength of MTA HP, a new high-plasticity calcium silicate-based cement

Braz. oral res. (Online); 30 (1), 2016
Abstract This study was designed to investigate the resistance to dislodgment provided by MTA HP, a new high-plasticity calcium silicate-based cement. Biodentine and White MTA Angelus were used as reference materials for comparison. Three discs 1 ± 0.1 mm thick were obtained from the middle third of the...

Dissolution of a mineral trioxide aggregate sealer in endodontic solvents compared to conventional sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study is to evaluate the solubility of a Mineral Trioxide Aggregate sealer (MTA-Fillapex) compared with five other sealers, calcium hydroxide (Sealapex), resin (Realseal), zinc oxide-eugenol (Tubli-Seal), and two epoxy resins (AH-26 and AH-Plus), in chloroform and eucalyptoil in ...

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...

Effect of root canal filling techniques on the bond strength of epoxy resin-based sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate the effects of different root canal filling techniques on the bond strength of epoxy resin-based sealers. Sixty single-rooted canines were prepared using ProTaper (F5) and divided into the following groups based on the root filling technique: Lateral Compact...
