introduction: the purpose of this study was to compare the push-out bond strength of white proroot mineral trioxide aggregate (mta), biodentine, calcium-enriched mixture (cem) cement and endosequence root repair material (errm) putty after exposure to blood. methods and materials: a total of 96 root dentin slices with a standardized thickness of 1.00±0.05 mm and standardized canal spaces were r...

introduction: mineral trioxide aggregate (mta) mixed with normal saline has short working time, delayed setting time, and poor consistency when used as an apical plug. a preliminary study suggested that substituting normal saline with ky jelly or 5% calcium chloride (cacl 2 ) as a vehicle expedites the setting time of mta. the present in vitro study compared the microleakage of proroot mta mixe...

introduction : recent investigations have attempted to improve regenerative endodontics with the help of stem cell therapy. in vitro studies have shown the ability of different agents to stimulate the differentiation of dental pulp stem cells (dpsc) into odontoblast-like cells. a combination of dexamethasone, β-glycerophosphate and vitamin d has been proven to induce a successful differentiatio...

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...
