this study aimed to compare the efficacy of mta and cem cement in class ii furcation defects in human mandibular molars.forty furcation defects were treated in 16 patients with chronic periodontitis. the clinical parameters of probing depth (pd), vertical and horizontal clinical attachment levels (vcal and hcal), open vertical and horizontal furcation depths (ovfd and ohfd), and gingival margin...

introduction: the provision of an effective apical seal is an essential factor when choosing an appropriate material for success of root-end surgeries. root-end resection, preparation and obturation should provide an adequate apical seal. the aim of this in vitro study was to investigate bacterial and dye microleakage of four different root-end filling materials and compare the efficacy of thes...

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...

The aim of this study was to evaluate the cytotoxicity of three types of calcium silicate-based endodontic cement after different incubation periods with human periodontal ligament fibroblasts. Human periodontal ligament fibroblasts were cultured from extracted third molars and seeded in 96-well plates. MTA, calcium enriched mixture (CEM) cement, and Biodentine were prepared and added to cultur...

introduction: the aim of this in vitro study was to determine the sealing ability of orthograde proroot mineral trioxide aggregate (mta) and calcium enriched mixture (cem) cement as root-end filling materials. materials and methods: fifty four extracted single-rooted human teeth were used. the samples were randomly divided into 3 experimental groups. in group a and b, 4 mm of wmta and cem cemen...

INTRODUCTION Particle size and distribution can influence the properties of materials. This study analyzed and compared the particle size of Root MTA, calcium hydroxide (CH), and a new endodontic cement called calcium enriched material (CEM). MATERIALS AND METHODS The particle size of each material was analyzed three times using 0.05 mg of test material with a particle size analyzer. The part...

OBJECTIVES This study aimed to compare the efficacy of MTA and CEM cement in Class II furcation defects in human mandibular molars. MATERIALS AND METHODS Forty furcation defects were treated in 16 patients with chronic periodontitis. The clinical parameters of probing depth (PD), vertical and horizontal clinical attachment levels (VCAL and HCAL), open vertical and horizontal furcation depths ...

Background and aims. Bonding of composite resin filling materials to pulp protecting agents produces an adhesive joint which is important for the quality of filling as well as success of restoration. We aimed to assess the bond strength of composite resin to three pulp capping biomaterials: Pro Root mineral trioxide aggregate (PMTA), Root MTA (RMTA) and calcium enriched mixture (CEM) cement, us...

Background and Aim: The use of ceramics has a long history. A new category of these materials was used in medicine in 1960 introduced as bioceramics. Biocompatibility, osteoinductivity and sealing ability are among the most favorable characteristics of endodontic bioceramics. Introduction of mineral trioxide aggregate (MTA) revolutionized endodontics and this new era is progressively growing. ...

introduction: this in vitro study measured and compared ph and phosphate and calcium ions release of a new endodontic material (cem cement), mineral trioxide aggregate (mta), and portland cement (pc) using uv-visible technique, atomic absorption spectrophotometry methods, and ph meter, respectively. materials and methods: each material was placed in a plastic tube (n=10) and immersed in a glass...
