INTRODUCTION Sealing ability of root-end filling materials is of great importance. It can be investigated by measuring microleakage. The purpose of this in vitro study was to evaluate microleakage of calcium enriched mixture (CEM) cement in two different media including phosphate buffer solution (PBS) and distilled water. MATERIALS AND METHODS Twenty single-rooted human teeth were selected. A...

background and aims. the aim of this study was to compare the biocompatibility of calcium-enriched mixture ce-ment (cem), composite resin and nano-particled mineral trioxide aggregate (np-mta) using human gingival fibroblasts. materials and methods. a comparative in vitro cell culture study was carried out using 60 single-rooted teeth which were assigned to the following four groups: 1) untreat...

in the present investigation, for the first time in iran, dewatered sludge waste from air heater washing wastewater treatment of a thermal power plant was subjected to investigation of the cement base stabilization and solidification experiments in order to reduce the mobility of heavy and other hazardous metals as well as increasing the compressive strength of the solidified product for possib...

introduction: this in vitro study compared the cytotoxic effects of three commercially available mta formulations naming proroot mta (pmta), angelus mta (amta), and root mta (rmta), with calcium-enriched mixture (cem) cement and a new nanohybrid mta (nmta) on human dental pulp stem cells (dpsc). methods and materials: four disc-shaped specimens of each material were prepared. after completion o...

INTRODUCTION Broken instruments in root canals complicate routine endodontic treatment. This study aimed to compare apical microleakage in root canals containing broken rotary instruments filled with mineral trioxide aggregate (MTA), calcium-enriched mixture (CEM) cement, laterally compacted gutta-percha and injected gutta-percha. METHODS AND MATERIALS In this in vitro, experimental study, 80...

INTRODUCTION The aim of the present study was to evaluate whether adding 2% chlorhexidine (CHX) and 2.6% sodium hypochlorite (NaOCl) to calcium-enriched mixture (CEM) cement would affect its setting time (ST), or not. METHODS AND MATERIALS In this study, the setting time of CEM cement was evaluated in three groups (n=9) as follows: group 1; CEM cement, group 2; CEM cement+2% CHX and group 3; ...

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...

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...

immediate restoration after vital pulp therapy is essential in order to create and maintain effective coronal seal.the aim of this study was to evaluate the shear bond strength of recently used pulp capping materials: white mineral trioxide aggregate (mta), and calcium enriched mixture cement (cem) to composite resin with the use of etch-and-rinse and self-etch adhesive systems and compare them...

introduction: the purpose of this study was to evaluate the effect of different solvents; carbonic acid (h 2 co 3 ), 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 ...
