Abstract Introduction: Thickness of a coronal seal barrier is an important factor for preventing microleakage. The aim of this in vitro study was to compare the sealing ability of two different thicknesses of calcium Enriched Mixture (CEM) cement as a coronal seal barrier.   Methods: A total of 40 canals of extracted maxillary central incisors were instrumented and obturated using lateral compa...

introduction: one of the hypotheses regarding the calcification induction by mineral trioxide aggregate (mta) is the involvement of transforming growth factor-beta (tgf- β ) super family. calcium-enriched mixture (cem) cement is one of the endodontic biomaterials with clinical applications similar to mta. the aim of the present in vitro study was to compare the induction of bone morphogenic pro...

background and aim: present study was designed to compare the bonding strength of resin-modified glass ionomer (rmgi) and composite resin to mineral trioxide aggregate (mta), mta mixed with na2hpo4 (namta), and calcium-enriched mixture (cem). materials and methods: thirty specimens of each cem, namta, and mta were prepared. composite and rmgi restorations were then placed on the samples (15 sam...

immediate restoration after vital pulp therapy is essential in order to create and maintain effective coronal seal.the aim of this study was to evaluate the shear bond strength of recently used pulp capping materials: white mineral trioxide aggregate (mta), and calcium enriched mixture cement (cem) to composite resin with the use of etch-and-rinse and self-etch adhesive systems and compare them...

introduction:  this  in vitro  study compared the apical sealing ability of three common root end filling materials namely mineral trioxide aggregate (mta), intermediate restorative material (irm) and calcium-enriched mixture (cem) cement using a bacterial leakage model.  methods and materials: the study was conducted on 83 single-rooted human teeth. tooth crowns were cut and root canals were p...

introduction: the aim of this study was to evaluate the effect of different mixing techniques on the ph and solubility of mineral trioxide aggregate (mta) and calcium-enriched mixture (cem). methods and materials: five samples were prepared from each biomaterial with different mixing techniques including hand-, amalgamator- or ultrasonic-mixing and were then placed in pre-weighted plastic tubes...

i ntroduction: nano-hydroxyapatite (nha) has been used for regeneration of osseous defects. calcium-enriched mixture (cem) cement is also used for various dental treatments. this trial compared the efficacy of nha and cem cement for direct pulp capping (dpc) of sound primary teeth. methods and materials: in this randomized clinical trial with split-mouth design, after attaining informed consent...

background and aim(s): this in vitro study compared the effects of mineral trioxide aggregate (mta), calcium enriched mixture (cem) cement, biodentine (bd) and octacalcium phosphate (ocp) on the viability of human gingival fibroblasts (hgfs). material and methods: after completion of the setting time of understudy materials, fibroblasts were placed in 24-well insert plates and 1mg of the unders...
