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 : to evaluate the clinical and radiographic outcomes of pulpotomy treatment with mineral trioxide aggregate (mta) in symptomatic mature permanent teeth with carious exposure. materials and methods: ten patients aged 27-54 years presented with 11 symptomatic permanent teeth ( n =11). each offending carious tooth was clinically and radiographically determined. we removed caries as co...

introduction: the aim of this randomized clinical trial was to compare the histologic pulp tissue response to one-step direct pulp capping (dpc) and miniature pulpotomy (mp) with mineral trioxide aggregate (mta) after application of dexamethasone in healthy human premolars. methods and materials: forty intact premolars from 10 orthodontic patients, were randomly chosen for dpc ( n =20) or mp ( ...

i ntroduction: the aim of this study was to evaluate the clinical and histological status of the pulp in sound human premolars after direct pulp capping (dpc) with four different dpc methods/materials. methods and materials: this study was conducted on eight volunteers who had to extract four first premolars due to orthodontic treatment. subsequent to tooth isolation, standardized class i occlu...

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...

Previous studies have demonstrated the efficacy of mineral trioxide aggregate (MTA) in repair of furcal perforation. In this article, the use of MTA in treating 2 cases of furcal perforation (accidental and caries-related) and subsequent long-term follow-up are described.

conclusions there was no significant statistical difference between mta and cem cement in sealing ability (p > 0.05). results the mean apical penetration of dye in the mta group was 0.94 mm while in the cem cement group this was 1.17 mm. eighty percent of the mta group and 75% of the cem cement group didn’t have any dye leakage. the p level was greater than 0.05 (0.592). materials and methods e...

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 ...
