A novel nanocomposite based on mycosynthesized bimetallic zinc-copperoxide nanoparticles, nanocellulose and chitosan: Characterization, antimicrobial and photocatalytic activities

BACKGROUND Recently, nanomaterials have received much attention due to their important role in solving medical and environmental problems. In the present study, a novel nanocomposite based on mycosyn thesized bimetallic zinc-copper oxides nanoparticles, nanocellulose, and chitosan was ready through an ec...

Degradation of Caffeine by Heterogeneous Photocatalysis Using ZnO with Fe and Ag

Abstract The organic compound caffeine when detected in environmental matrices such as surface waters and groundwater is considered as an emerging contaminant, in which its effects are still unknown. Therefore, in the present research, zinc oxide-based catalysts impregnated with iron and silver were prep...

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...

Influence of chlorhexidine and zinc oxide in calcium hydroxide pastes on pH changes in external root surface

Abstract The objective of this study was to assess the influence of chlorhexidine (liquid and gel) and zinc oxide in calcium hydroxide (CH) pastes on root pH in simulated external resorption. One hundred human anterior teeth with a single root canal were selected. After decoronation and root canal instru...

Model resin composites incorporating ZnO-NP: activity against S. mutans and physicochemical properties characterization

J. appl. oral sci; 26 (), 2018
Abstract Although resin composites are widely used in the clinical practice, the development of recurrent caries at composite-tooth interface still remains as one of the principal shortcomings to be overcome in this field. Objectives To evaluate the activity against S. mutans biofilm of model resin comp...

Molecular and morphological surface analysis: effect of filling pastes and cleaning agents on root dentin

J. appl. oral sci; 25 (1), 2017
Abstract The quality of the dentin root is the most important factor for restoration resin sealing and drives the outcome of endodontic treatment. Objective This study evaluated the effect of different filling pastes and cleaning agents on the root dentin of primary teeth using Fourier-transformed Rama...
