OBJECTIVES The purpose of the study was to evaluate human dental pulp response to pulpotomy with calcium hydroxide (CH), mineral trioxide aggregate (MTA), and calcium enriched mixture (CEM) cement. MATERIALS AND METHODS A total of nine erupted third molars were randomly assigned to each pulpotomy group. The same clinician performed full pulpotomies and coronal restorations. The patients were ...

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...

INTRODUCTION The antibacterial effects of calcium hydroxide (CH), mineral trioxide aggregate (MTA), and calcium enriched mixture (CEM) cement against various spp. of microorganisms were assessed in-vitro using agar diffusion test. MATERIALS AND METHODS A base layer of Petri plates was made using Muller-Hinton agar. Four cavities were made in agar and filled with freshly mixed materials after ...

introduction: the aim of this study was to compare the marginal adaptation of mineral trioxide aggregate (mta) and calcium-enriched mixture(cem) cement apical plugs in open apex teeth in dry, blood- and saliva-contaminated canals. methods and materials: a total of 120 human extracted single-rooted teeth were used. the teeth were decoronated and canals were cleaned and shaped up to #80 k-files. ...

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...

The dephosphorization slag has a great potential as the secondary resources of manganese and phosphorus, while quite a large amount of slag is landfilled and simply reused such as cement. The objective of this study is to investigate the recovery of manganese and phosphorus by wet magnetic separation technique. The hot metal pretreatment slag (dephosphorization slag) generally contains a Ca3P2O...

INTRODUCTION The purpose of this study was to compare the push-out bond strength of white ProRoot Mineral Trioxide Aggregate (MTA), Biodentine, calcium-enriched mixture (CEM) cement and Endosequence Root Repair Material (ERRM) putty after exposure to blood. METHODS AND MATERIALS A total of 96 root dentin slices with a standardized thickness of 1.00±0.05 mm and standardized canal spaces were r...

Commonly used implants for therapeutic approaches of non-systemically impaired bone do not sufficiently support the healing process of osteoporotic bone. Since strontium (II) has been proven as an effective anti-osteoporotic drug new types of strontium enriched calcium phosphate bone cements were developed. As osteoporosis is characterized by an imbalance of osteoblast and osteoclast activity t...

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...

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...
