mta (mineral trioxide aggregate) علی رغم خصوصیات کاربردی عالی , به علت زمان ستینگ طولانی و استحکام فشاری و خمشی نسبتاً پایین در کوتاه مدت , استفاده از آن مستلزم صرف وقت کلینیکی زیاد و محدود به نواحی کم تنش می باشد. سیمان پرتلند که با mta شباهت ساختاری دارد با افزودن ذرات نانو سیلیکا تغییرات فیزیکی و مکانیکی مناسبی پیدا کرده است. لذا هدف از این مطالعه بررسی نقش نانو ذرات سیلیکا بر برخی خواص مکانی...
Aim: The aim of this study was to compare the effect of an acidic and alkaline environment on the compressive strength of Grey Pro Root Mineral Trioxide Aggregate and Biodentine. Methodology: A total of eightyhuman, mandibular molars were used. Perforations were made in the furcation of each molar and enlarged to #3 Pesso drills. The repair was performed, according to the materials used. Sample...
This case report describes the treatment of two immature maxillary central incisors in a 7-year-old female patient. She suffered complicated crown fracture because of trauma, and the root formation was incomplete. White mineral trioxide aggregate (MTA) was selected as the pulp-capping material after cervical pulpotomy to preserve the pulp tissue vitality and achieve maturogenesis. Follow-up eva...
OBJECTIVE The aim of this study was to present a review of the reported literature on: (i) the physical and chemical properties; and (ii) clinical applications of mineral trioxide aggregate (MTA) in the practice of paediatric dentistry. METHOD Electronic literature search of scientific papers from January 1993 to June 2008 was carried out on the MEDLINE, Embase, Entrez Pubmed, and Scopus data...
The purpose of this in vitro study was to compare the apical sealing ability of mineral trioxide aggregate and glass ionomer cement by a dye penetration test. It was carried out at Queen Marry and Westfield College, University of London during 2010-2011 session. Time duration was 6 months. A total of 16 samples of elephant tusk dentine (ivory) were prepared and finished for dye penetration test...
Objective: The Purpose of this investigation was to assess the effectiveness of Mineral Trioxide Aggregate in providing an apical seal in comparison with High Copper Silver Amalgam, Conventional Glass Ionomer Cement Type 2, and Glass Cermet cement by using a dye penetration method. Methods: The root canals of seventy extracted teeth were instrumented and obturated with gutta-percha. Each tooth ...
INTRODUCTION Coronal leakage seems to play an important role in the failure of endodontic treatment. A double seal over root canal filling has been suggested as a means of improving the coronal seal. Several restorative materials have been used in an attempt to produce a coronal barrier. The purpose of this study was to assess gray-coloured mineral trioxide aggregate (GMTA), white-coloured mine...

The purpose of this investigation was to study, in vitro, the antifungal effect of mineral trioxide aggregate (MTA) using a tube-dilution test. MTA was tested freshly mixed and after 24 h set on Candida albicans. The tested MTA was incubated with C. albicans for 1 h, 24 h, and 3 days. Results showed that the freshly mixed MTA was effective in killing the tested fungi after 1 day of contact, whe...
The Dirac reduction technique used previously to obtain solutions of the classical dynamical Yang-Baxter equation on the dual of a Lie algebra is extended to the PoissonLie case and is shown to yield naturally certain dynamical r-matrices on the duals of Poisson-Lie groups found by Etingof, Enriquez and Marshall in math.QA/0403283.
