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 ...

introduction: the aim of the present study was to evaluate the effect of different mixing techniques (conventional, amalgamator and ultrasonic mixing) on the physical properties the working time (wt), setting time (st), dimensional changes (dc) and film thickness (ft)] of calcium-enriched mixture (cem) cement and mineral trioxide aggregate (mta). methods and materials: the mentioned physical pr...

in modern endodontics, vital pulp therapy (vpt) has been considered an ultra-conservative treatment modality. based on the level of pulp preservation, vpt includes stepwise excavation, indirect pulp capping (idpc), direct pulp capping (dpc), miniature pulpotomy (mp), partial/cvek pulpotomy and coronal/complete pulpotomy (cp). the present article reviews the treatment outcomes of 94 permanent te...

the present report reviews the diagnostic and treatment challenges of a mandibular molar with previous root canal treatment and signs of a procedural mishap, i.e. furcal radiolucency and localized swelling of the gingival margin in which a sinus tract was present. by tracing the sinus tract, it became evident that the lesion originated from the furcation area, not the root apices. this case was...

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...

introduction: adequate seal of iatrogenically perforated area within the root canal system can improve the long term treatment prognosis. this in vitro study evaluated the sealing ability of mineral trioxide aggregate (mta), calcium-enriched mixture (cem) cement and biodentine in repair of furcation perforation in primary molars. methods and materials: a total of 61 freshly extracted primary ma...

maintaining deciduous teeth in function until their natural exfoliation is absolutely necessary. vital pulp therapy (vpt) is a way of saving deciduous teeth. the most important factors in success of vpt are the early diagnosis of pulp and periradicular status, preservation of the pulp vitality and proper vascularization of the pulp. development of new biomaterials with suitable biocompatibility...

introduction: this laboratory study was performed to evaluate the effect of different acidic ph values on the push-out bond strength of calcium-enriched mixture (cem) cement. methods and materials: forty-eight root dentin slices were obtained from freshly extracted single rooted human teeth and their lumen were instrumented to achieve a diameter of 1.3 mm. then, cem cement was mixed according t...

statement of problem: calcium hydroxide which is commonly used as an intracanal medicament, changes the ph of dentin and periradicular tissues to an alkaline ph. in some clinical situations, endodontic reparative cements like calcium enriched mixture cement are used after calcium hydroxide therapy. however, the alkaline ph may affect the physical properties of this cement. objectives: this stud...
