introduction: ca(oh) 2 -containing/forming materials are conventionally used for indirect pulp-capping and are theoretically able to release ca 2+ and oh - ions for hydrolytic dissociation. however, no evidence exists for ion diffusion through the remaining coronal dentin. the aim of this study was to design an innovative experimental set-up to test the ability of ca(oh) 2 -containing and ca(oh...

To compare the physicochemical composition of 4 MTAs commercially available in Latin America. ProRoot MTA (Dentsply, USA), Angelus (Angelus, Brazil), Flow (Ultradent, and Viarden (Viarden, Mexico) were physically chemically compared. Scanning electron microscopy (SEM) images obtained from powder prepared presentations. Energy Dispersive X-Ray Spectroscopy (EDS) analyses performed by triplicate,...

BioAggregate is a new product that was formulated for root-end filling, perforation repair, and pulp capping. This study examined the chemical differences between white mineral trioxide aggregate (MTA) and BioAggregate in both powder and set forms using X-ray diffraction. The results showed that white MTA and BioAggregate have a similar chemical composition with some differences: BioAggregate c...

this study compared the marginal adaptation of mineral trioxide aggregate (mta) and mta-like materials as root-end fillings after incubation in phosphate buffer saline (pbs), a synthetic tissue fluid, for either 1 week or 2 months.in this experimental study, seventy-two extracted human single-rooted teeth were prepared and obturated with gutta-percha and ah26 sealer. the apical 3 mm of the root...

The ability of two mineral trioxide aggregate (MTA) compounds and Intermediate Restorative Material (IRM) to seal large furcation perforations were evaluated using a dye-extraction leakage method. The furcation perforations were repaired with and without the use of internal matrix before placement of repair material. Eighty extracted human mandibular first molars were divided into positive (n =...

introduction: mineral trioxide aggregate is being widely used for root end filling, pulp capping, perforation repair, and other endodontic procedures. recently, a material similar to proroot mineral trioxide aggregate (pmta) was developed in iran named root mineral trioxide aggregate (rmta) with the claim of having the exact result of original mta. the purpose of this study was to compare the a...

INTRODUCTION Stem cell technology has been a great hope for the regeneration of cells of pulp-dentin complex and dental structures together with surrounding bone and periodontium. The main challenge in the regeneration process is a successful combination of stem cells and efficient inductors such as inductive biomaterials. In this regard, today, manufacturers propose novel tooth filling materia...
