Background: Inadequate seal at the apex is substantial cause for surgical endodontic dissatisfaction. The retrograde filling material which used should prevent egress of potential contaminants into periradicular tissue.
 Objectives: To evaluate ability MTA Angelus, Zirconomer and Bioactive bone cement to root end as material; compare sealing these three different materials with apices rese...

his study evaluated the sealing ability of apical plugs fabricated with gray MTA Angelus sealer, CPM TM sealer and MBPc sealer. The root canals of 98 extracted single-rooted human teeth were instrumented with #5 to #1 Gates Glidden drills according to the crown-down technique until the #1 drill could pass through the apical foramen. The specimens were then prepared with K-files, starting with a...

INTRODUCTION This in vitro study compared the cytotoxic effects of three commercially available MTA formulations naming ProRoot MTA (PMTA), Angelus MTA (AMTA), and Root MTA (RMTA), with calcium-enriched mixture (CEM) cement and a new nanohybrid MTA (NMTA) on human dental pulp stem cells (DPSC). METHODS AND MATERIALS Four disc-shaped specimens of each material were prepared. After completion o...

The aim of this study was to evaluate the antimicrobial activity of a new root canal sealer containing calcium hydroxide (Acroseal) and the root canal sealer based on MTA (Endo CPM Sealer), in comparison with traditional sealers (Sealapex, Sealer 26 and Intrafill) and white MTA-Angelus, against five different microorganism strains. The materials and their components were evaluated after manipul...

OBJECTIVES Tricalcium silicate is the major constituent phase in mineral trioxide aggregate (MTA). It is thus postulated that pure tricalcium silicate can replace the Portland cement component of MTA. The aim of this study was to evaluate bond strength of methacrylate-based (MB) composites, silorane-based (SB) composites, and glass ionomer cement (GIC) to Biodentine® and mineral trioxide aggreg...

Introduction. In addition to good biological properties, biomaterials should also possess appropriate physical properties in order provide stability and longevity at the place of application. The aim this work was evaluate an experimental nanostructured material based on calcium aluminate (CAL) silicate (CS). Material method. research used synthesized by hydrothermal solgel method from individu...

BACKGROUND Mineral trioxide aggregate (MTA) is a biomaterial that has been investigated for endodontic applications. With the increased use of MTA in pulp capping, pulpotomy, perforation repair, apexification and obturation, the material that would be placed over MTA as a final restoration is an important matter. As composite resins are one of the most widely used final restorative materials, t...

Avaliou-se a influência da utilização agitação ultrassônica na resistência de união à dentina, por meio push-out, proporcionada pelos cimentos MTA-Angelus branco (MTA) e Biodentine (BD), empregados no selamento perfurações furca. Foram utilizados 48 primeiros ou segundos molares inferiores, com raízes não fusionadas, distantes cerca 2 mm entre si porção cervical das mesmas. Os dentes foram aces...
