background: the ability of mineral trioxide aggregate (mta) to strengthen the tooth structure has been studied with contradictory results, and there is a lack of data in the case of calciumenriched mixture (cem) cement as a novel endodontic biomaterial. the aim of the present study was to evaluate the reinforcing effect of mta and cem cement on simulated immature teeth. materials and methods: t...

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 ...

There is an increasingly rich literature about Bayesian nonparametric models for clustering functional observations. Most recent proposals rely on infinite-dimensional characterizations that might lead to overly complex cluster solutions. In addition, while prior knowledge the shapes typically available, its practical exploitation be a difficult modeling task. Motivated by application in e-comm...

INTRODUCTION The aim of this in vitro study was to evaluate the effect of 2% chlorhexidine (CHX) on the push-out bond strength (BS) of calcium-enriched mixture (CEM) cement. METHODS AND MATERIALS Root-dentin slices from 60 single-rooted human teeth with the lumen diameter of 1.3 mm were used. The samples were randomly divided into 4 groups (n=15), and their lumens were filled with CEM cement ...

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...

INTRODUCTION The purpose of this in vitro study was to compare the antibacterial activity of Calcium Enriched Mixture (CEM) with ProRoot Mineral Trioxide Aggregate (MTA) against Enterococcus faecalis (E. faecalis) in the presence/absence of dentin powder. MATERIALS AND METHODS Two series of freshly mixed (10, 50, and 100 mg), set crushed powder (10, 50, and 100 mg), and pieces of uncrushed se...
