background: one ideal property of a root-end fi lling material is its apical sealing ability. the aim of this in vitro study was to assess bacterial and dye microleakage of white and gray mineral trioxide aggregate (wmta and gmta), portland cement and calcium-enriched mixture (cem) cement used as root-end fi lling material, and to assess the agreement between these two test methods. materials a...

The purpose of a root-end filling is to establish a seal between the root canal space and the periradicular tissues. As root-end filling materials come into contact with periradicular tissues, knowledge of the tissue response is crucial. Almost every available dental restorative material has been suggested as the root-end material of choice at a certain point in the past. This literature review...

AIM The aim of this study was to evaluate the minimum bactericidal concentrations (MBC) of root-end filling materials ProRoot MTA, MTA Angelus and IRM. MATERIALS AND METHODS Macrodilution broth method was used. Microorganisms used were: Staphylococcus aureus (ATCC 29213), Enterococcus faecalis (ATCC 29212) and Streptococcus mutans. Serial two-fold dilutions of root-end filling samples were pr...

Nowadays, in endodontic field mineral trioxide aggregate (MTA; Dentsply, Tulsa Dental, Tulsa, OK, USA) has been introduced and widely used in many indications such as root-end filling, perforation repair, apexification, and pulp capping. Traditionally, various materials, such as amalgam, zinc oxide eugenol (ZOE), Intermediate Restorative Material (IRM; Dentsply Caulk, Milford, DE, USA), and sup...
