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...

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...

INTRODUCTION The aim of this in vitro study was to evaluate the effect of calcium hydroxide (CH) on push-out bond strength of white mineral trioxide aggregate (WMTA) and calcium-enriched mixture (CEM) cement in simulated furcation perforations. METHODS AND MATERIALS Furcation perforations, measuring 1.3 mm in diameter and 2 mm in height, were created in 80 human mandibular first molars. The t...

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...

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...

Introduction the aim of the present study was to evaluate the influence of propylene glycol (PG) on the flowability, microhardness, pH and calcium ion release of calcium-enriched mixture (CEM). Methods and Materials CEM cement was mixed with different proportions of PG, as follows: group 1,100% CEM liquid (CL); group 2, 100% PG; group 3, 50% PG and group 4, 20% PG. For assessment of flowabili...

introduction:  this  in vitro  study compared the apical sealing ability of three common root end filling materials namely mineral trioxide aggregate (mta), intermediate restorative material (irm) and calcium-enriched mixture (cem) cement using a bacterial leakage model.  methods and materials: the study was conducted on 83 single-rooted human teeth. tooth crowns were cut and root canals were p...

INTRODUCTION Microleakage is of the causes of endodontic treatment failure. The aim of this in vitro study, was to compare the microleakage of mineral trioxide aggregate (MTA) and calcium-enriched mixture (CEM) cement apical plugs in three environments. METHODS AND MATERIALS A total of 130 human extracted single rooted teeth were collected. After decoronation, preparation of the root canal sp...
