Penetration of bioceramic and epoxy-resin endodontic cements into lateral canals

Abstract: The aim of the present study was to assess the penetration capacity of two endodontic cements, Endosequence BC Sealer and AH Plus, in artificial lateral canals. Twenty-six two-rooted, maxillary first premolars were instrumented to size 40.06 using K3 files. In each root, six lateral canals of t...

J. appl. oral sci; 26 (), 2018
Abstract Objective This study aimed to analyze the following physicochemical properties: radiopacity, final setting time, calcium release, pH change, solubility, water sorption, porosity, surface morphology, and apatite-forming ability of two calcium silicate-based materials. Material and methods We te...

Evaluation of the sealing ability of different root canal sealers: a combined SEM and micro-CT study

J. appl. oral sci; 26 (), 2018
Abstract Objective: The purpose of this study was to analyze the ability of multiple compounds to seal the dental tubules using scanning electron microscopy (SEM) and micro-computed tomogra-phy (micro-CT). Material and Methods: Twenty-four single-root human mandibular premolars were selected and instru...

Influence of β-tricalcium phosphate of different geometric shape on the morphology of regeneration of experimental defect of compact bone tissue

Actual. osteol; 13 (1), 2017
Purpose: to compare the healing process of a defect of compact bone tissue after the implantation of osteoplastic materials based on β-tricalcium phosphate (“ChronOS™” and “Calc-i-oss®”), which differ by manufacturer, geometrical shape and microscopic structure. Methods: the experiment was pe...

Effect of two desensitizing agents on dentin permeability in vitro

J. appl. oral sci; 25 (1), 2017
Abstract Objective The aim of this in vitro study was to investigate the effect of two desensitizing agents and water on hydraulic conductance in human dentin. Material and Methods GLUMA Desensitizer PowerGel (GLU) contains glutaraldehyde (GA) and 2-hydroxyethyl methacrylate (HEMA), and Teethmate Des...

In vivo performance of different scaffolds for dental pulp stem cells induced for odontogenic differentiation

Braz. oral res. (Online); 30 (1), 2016
Abstract This study was designed to determine the in vivo performance of three different materials as scaffolds for dental pulp stem cells (DPSC) undergoing induced odontogenic differentiation. An odontogenic medium modified by the addition of recombinant human bone morphogenetic protein 2 was used in th...
