INTRODUCTION The aim of the present study was to evaluate the effect of different mixing techniques (conventional, amalgamator and ultrasonic mixing) on the physical properties the working time (WT), setting time (ST), dimensional changes (DC) and film thickness (FT)] of calcium-enriched mixture (CEM) cement and mineral trioxide aggregate (MTA). METHODS AND MATERIALS The mentioned physical pr...

introduction: in cases of limited access to the surgical site, an alternative approach is to obturate the canal prior to surgery. endodontic surgery is subsequently performed by root-end resection without retro-cavity preparation. this in vitro study was designed to compare the sealing ability of resected roots filled with either mineral trioxide aggregate (mta) or calcium enriched mixture (cem...

introduction: there are numerous factors that can lead to tooth discoloration after endodontic treatment, such as penetration of endodontic materials into the dentinal tubules during root canal treatment. the aim of this in vitro study was to compare discoloration induced by tooth colored mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) cement in extracted human teeth. method...

INTRODUCTION The aim of this in vitro study was to evaluate the tooth discoloration induced by calcium-enriched mixture (CEM) cement and mineral trioxide aggregate (MTA). METHODS AND MATERIALS Forty five endodontically treated human maxillary central incisors were selected and divided into three groups (n=15) after removing the coronal 3 mm of the obturating materials. In the MTA group, white...

i ntroduction: many of highly-alkaline dental materials have some adverse effects on physical properties of dentin. as basic substances, mineral trioxide aggregate (mta), calcium hydroxide (ch) and the new endodontic material, calcium-enriched mixture (cem) cement, may adversely affect dentin. the purpose of this in vitro study was to evaluate the effect of long-term application of cem cement, ...

INTRODUCTION Sealing ability is an important factor for a root-end filling material in endodontic surgeries. This in vitro study aimed to compare the sealing ability of mineral trioxide aggregate (MTA) and a new endodontic cement named calcium enriched mixture (CEM) cement as root-end filling materials. MATERIALS AND METHODS The experiments were carried out in dry, saliva or blood contaminate...

AIM The aim of this study was to compare the bacterial leakage of mineral trioxide aggregate (MTA), calciem enriched cement (CEM), and bone cement (BC) as repair materials in furcal perforations. METHODS The pulp chambers of 57 human mandibular molar teeth were accessed and the root canal orifices were located. The roots were horizontally sectioned in the middle third. Composite resin was use...

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: the aim of this trial was to compare clinical and radiographic success rates of direct pulp capping (dpc) using a novel biomaterial called calcium enriched mixture (cem) cement versus mineral trioxide aggregate (mta) in primary molar teeth. materials and methods: in this randomized clinical trial 42 deciduous molars in 21 patients who had at least two teeth requiring dpc, were tre...

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...
