introduction: this case report describes apexogenesis treatment of three molar teeth of an 8-year-old boy using three different pulpotomy agents. methods: pulpotomy was performed on decayed immature molar teeth with established irreversible pulpitis and the remaining pulp was capped with either zinc oxide eugenol, proroot mineral trioxide aggregate or calcium-enriched mixture (cem) cement. teet...

INTRODUCTION Propylene glycol (PG) improves the handling, physical, and chemical properties of mineral trioxide aggregate (MTA). This study aimed to evaluate the effect of PG on the sealing ability of MTA and calcium-enriched mixture (CEM) apical barriers. METHODS AND MATERIALS A total of 70 extracted human maxillary single-rooted teeth were prepared using ProTaper rotary system. The apical 3...

This case report presents the successful surgical treatment of a symptomatic open apex upper central incisor with a failed overfilled mineral trioxide aggregate (MTA) apical plug. Unintentional overextension of the MTA had occurred two years before the initial visit. An apical lesion adjacent to the excess MTA was radiographically detectable. Endodontic surgery was performed using calcium-enric...

introduction: flow rate (fr) and compressive strength (cs) are important properties of endodontic biomaterials that may be affected by various mixing methods. the aim of this experimental study was to evaluate the effect of different mixing methods on these properties of mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) cement. materials and methods: hand, amalgamator and ultr...

introduction: the aim of this randomized controlled trial was to compare the radiographic and clinical success rates of direct pulp capping (dpc) using proroot mineral trioxide aggregate (mta) or calcium enriched mixture (cem). methods and materials: a total of 42 symptom-free carious vital primary molars (21 pairs) were selected in this split mouth trial and randomly pulpotomized in two experi...

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...

OBJECTIVES The aim of this study was to evaluate the water absorption and the amount of hydroxyethyl metacrylate (HEMA) level released from various resin modified glass ionomer cements. METHODS Advance, Vitremer and Protec-Cem resin modified glass ionomer cements were used to evaluate the HEMA release. Ten specimens were fabricated from each cement in 10 x 1 mm height. Thirty specimens were i...

A large amount of blast furnace slag is generated in China. Most ground granulated blast furnace slag (GGBS) however ends up in low-grade applications. Blast furnace slag, ground to an appropriate fineness, can be used as a partial replacement of cementitious material in concrete. The potential for using GGBS in structural concrete, e.g. concrete beams and columns is investigated at Xi’an Jiaot...

Background The aim of this study was to evaluate the discoloration induced by CEM cement, Portland cement (PC) and MTA mixed with propylene glycol (MTA-PG) in comparison to White MTA. Material and Methods Ninety extracted premolar and canine teeth were resected 2 mm below the CEJ. The coronal part of crown was prepared with peeso reamer and Gates-Glidden drills, and the specimens were randoml...

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 cemen...
