there is some concern that root resection may alter the seal of the previously set orthograde material. the aim of this study was to evaluate the apical sealing ability of orthograde mineral trioxide aggregate (mta) and calcium enriched mixture (cem) plugs after resection of the roots.the fluid filtration method was carried out on a total of 51 roots in three experimental (n=15) and two control...

OBJECTIVES Recently, it was shown that NanoMTA improved the setting time and promoted a better hydration process which prevents washout and the dislodgment of this novel biomaterial in comparison with WTMA. This study analyzed the compressive strength of ProRoot WMTA (Dentsply), a NanoWMTA (Kamal Asgar Research Center), and Bioaggregate (Innovative Bioceramix) after its exposure to a range of e...

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...

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...
