Physicochemical properties of calcium silicate-based formulations MTA Repair HP and MTA Vitalcem

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...

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...

Solubility, porosity and fluid uptake of calcium silicate-based cements

J. appl. oral sci; 26 (), 2018
Abstract Objective: To evaluate the absorption/fluid uptake, solubility and porosity of White mineral trioxide aggregate (MTA) Angelus, Biodentine (BIO), and zinc oxide-eugenol (ZOE). Material and Methods: Solubility was evaluated after immersion in distilled water for 7 and 30 days. Porosity was evalu...

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...

Crystal Modification on Lithium Disilicate Glass Ceramics Sintered Using Microwaves

ABSTRACT: Microwaves are an interesting alternative to process dental ceramics. It is well documented that Microwave Hybrid Sintering (MHS) allows important savings in time and energy consumption. However, little is known about its effect on lithium disilicate glass ceramics, a popular material in dentis...

Physical properties and biological effects of mineral trioxide aggregate mixed with methylcellulose and calcium chloride

J. appl. oral sci; 25 (6), 2017
Abstract Objectives: Methylcellulose (MC) is a chemical compound derived from cellulose. MTA mixed with MC reduces setting time and increases plasticity. This study assessed the influence of MC as an anti-washout ingredient and CaCl2 as a setting time accelerator on the physical and biological propertie...

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 photodynamic therapy and non-thermal plasma on root canal filling: analysis of adhesion and sealer penetration

J. appl. oral sci; 25 (4), 2017
Abstract Objective The aim of this study was to evaluate the effect of photodynamic therapy (PDT) and non-thermal plasma (NTP) on adhesion and sealer penetration in root canals. Material and Methods Sixty single-rooted premolars were used. The teeth were prepared using a crown-down technique. NaOCl a...

Crown discoloration promoted by materials used in regenerative endodontic procedures and effect of dental bleaching: spectrophotometric analysis

J. appl. oral sci; 25 (2), 2017
Abstract Regenerative endodontic procedure (REP) has been proposed as a new approach to treat immature permanent teeth. However, materials used in REP for root canal disinfection or cervical sealing may induce tooth discoloration. Objectives To assess tooth crown’s color after intracanal treatmen...

Enhanced bioactive properties of BiodentineTM modified with bioactive glass nanoparticles

J. appl. oral sci; 25 (2), 2017
Abstract Objective To prepare nanocomposite cements based on the incorporation of bioactive glass nanoparticles (nBGs) into BiodentineTM (BD, Septodent, Saint-Maur-des-Fosses Cedex, France) and to assess their bioactive properties. Material and Methods nBGs were synthesised by the sol-gel method. BD ...
