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: Sealing ability of a retrograde filling material is an important factor for a successful endodontic apicoectomy. The purpose of this in-vitro study was to compare the sealing ability of calcium enriched mixture (CEM) cement versus amalgam as root-end filling materials. Methods: A total of 36 canals of extracted maxillary central incisors were instrumented and obturated using later...

introduction: the aim of this in vitro study was to compare polymicrobial microleakage of calcium enriched mixture (cem) cement, mineral trioxide aggregate (mta), amalgam, and composite resin as intra-orifice sealing materials. materials and methods: seventy single-rooted mandibular premolars were instrumented and obturated by cold lateral compaction technique. the teeth were randomly divided i...

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 ...

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...

introduction: endodontic treatment in pulpless immature teeth is challenging due to the lack of an apical stop. insertion of an apical plug is an alternative to conventional long-term apexification with calcium hydroxide. the aim of this study was to compare the apical microleakage of mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) cement as apical plugs with three different...

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...

Iatrogenic perforation of the furcation area in multi-rooted molars during preparation of the access cavity can potentially lead to tooth extraction. The present case report describes the nonsurgical endodontic management of an extensive pulp chamber floor perforation in a first mandibular molar with calcium enriched mixture (CEM) cement. The perforation was chemically cleaned and then physical...
