Ethylenediaminetetraacetic acid (EDTA)-treated dentin matrix (TDM) is an enriched source of bioactive molecules. Therefore, it was hypothesized that fabrication of autogenous TDM on root dentinal walls of necrotic immature permanent teeth may allow more predictable outcome of revascularization treatments. Two young patients with permanent nonvital immature teeth were chosen for revascularizatio...

This article describes successful use of calcium-enriched mixture (CEM) cement and Biodentine in apexogenesis treatment in two 8-year-old patients, one with immature permanent molar diagnosed primarily with irreversible pulpitis and the other with partially vital maxillary central incisor. After access cavity preparation, partial pulpotomy in molar and full pulpotomy in central was performed, a...

INTRODUCTION Flow rate (FR) and compressive strength (CS) are important properties of endodontic biomaterials that may be affected by various mixing methods. The aim of this experimental study was to evaluate the effect of different mixing methods on these properties of mineral trioxide aggregate (MTA) and calcium-enriched mixture (CEM) cement. MATERIALS AND METHODS Hand, amalgamator and ultr...

OBJECTIVES This study was performed to evaluate the cytotoxicity of four calcium silicate-based endodontic cements at different storage times after mixing. MATERIALS AND METHODS Capillary tubes were filled with Biodentine (Septodont), Calcium Enriched Mixture (CEM cement, BioniqueDent), Tech Biosealer Endo (Tech Biosealer) and ProRoot MTA (Dentsply Tulsa Dental). Empty tubes and tubes contain...

The MKK3-p38 MAPK pathway has been reported to mediate larval settlement in Amphibalanus (=Balanus) amphitrite. To clarify the underlying molecular mechanism, we applied label-free proteomics to analyze changes in the proteome of cyprids treated with a p38 MAPK inhibitor. The results showed that the expression levels of 80 proteins were significantly modified (p < 0.05). These differentially ex...

INTRODUCTION This study aimed at evaluating the sealing properties of calcium-enriched mixture (CEM) compared to mineral trioxide aggregate (MTA) as a cervical barriers in intra-coronal bleaching. METHODS AND MATERIALS In this in vitro study, endodontic treatment was performed on 60 extracted human incisors and canines without canal calcification, caries, restorations, resorption or cracks. T...

The cement industry is an important industrial entity responsible for implementing carbon emission reduction targets. Considering the trading and green certificate mechanisms, this paper presents a multi-stage planning approach constructed Cement-Industrial Integrated Energy System (Cement-IIES). Carbon technologies represented by low-temperature waste heat recovery, as well phased changes in e...

INTRODUCTION The purpose of this study was to evaluate the effect of different solvents; carbonic acid (H2CO3), hydrochloric acid (HCl), chlorhexidine (CHX) and sodium hypochlorite (NaOCl) on the surface hardness of mineral trioxide aggregate (MTA) and calcium-enriched mixture (CEM) cement. METHODS AND MATERIALS Plexiglass molds were prepared and filled with Angelus MTA or CEM cement and then...
