سابقه و هدف: روش معمول استفاده از mta تامین رطوبت از طریق کن کاغذی مرطوب برای حداقل 4 ساعت می باشد. با توجه به اشاره بعضی مطالعات به کافی بودن رطوبت حاصل از بافت های پری اپیکال برای ست شدن mta، این مطالعه با هدف مقایسه درمان یک جلسه ای و دو جلسه ای اپکسیفیکاسیون با استفاده از پلاگ mta انجام گردید.مواد و روشها: در این مطالعه تجربی آزمایشگاهی، تعداد 70 دندان تک کاناله کشیده شده انسان مورد بررسی ق...
Carrier and syringe-type devices are currently used to deliver mineral trioxide aggregate as a root-end filling material. In certain surgical situations these devices may be too difficult to use because of the location of the surgical site and the small size of the root-end preparation. This paper describes a new technique to overcome these difficulties by the formation and delivery of mineral ...
INTRODUCTION Pulpotomy is a specific treatment used to save root pulp, in which only the inflamed coronal pulp is removed and capping materials are placed. Our study aims to study the effect of simvastatin (1) on the proliferation and differentiation of dental pulp stem cells (DPSCs) and (2) on DPSC-induced pulp regeneration after pulpotomy. METHODS DPSCs were treated with different concentra...
Amalgam, IRM, and a mineral trioxide aggregate were tested for repair of experimentally created root perforations. Fifty sound, extracted mandibular and maxillary molars were used in this study. A perforation was created on the mesial root surface at about a 45-degree angle to the long axis of each tooth. The tooth was then placed into a saline-soaked "Oasis" to simulate a clinical condition. A...
Introduction: The aim of this study was to evaluate the sealing ability of Bioactive glass (BG) and Bioactive glass-Hydroxyapatite (BG-HA) in comparison to Mineral Trioxide Aggregate (MTA). Methods: The sealing ability of Bioactive glass and Bioactive glass-hydroxyapatite mixed with glass ionomer cement and Mineral Trioxide Aggregate used as retrograde filling material was assessed by bacterial...
objectives: mineral trioxide aggregate (mta) is extensively used in endodontics. however, mta is difficult to handle because of its granular consistency, low mechanical properties and initial looseness. the objective of this study was to assess the compressive strength (cs), diametral tensile strength (dts), and ph of set mta using methyl cellulose as liquid. materials and methods: white proroo...
introduction: biocompatibility and antimicrobial activity of endodontic materials are of utmost importance. considering the extensive applications of mineral trioxide aggregate (mta) in dentistry and antimicrobial properties of silver nanoparticles, this study aimed to evaluate the subcutaneous inflammatory reaction of rat connective tissues to white mta with and without nanosilver (ns) particl...
زمینه و هدف: هدف از درمان ریشه، سیل کامل و سه بعدی سیستم کانال ریشه از دهانه تا تنگه اپیکال می باشد؛ از این رو پرفوراسیون های حین درمان ریشه، به دلایل پوسیدگی، درمان غلط یا تحلیل ها باید به وسیله مواد مناسب بسته و مهر و موم گردند. مطالعه حاضر با هدف مقایسه بافت شناختی اثر دو ماده از جنس mineral trioxide aggregate با نامهای root mta و pro root mta، جهت ترمیم پرفوراسیون های فورکا در دندانهای تکام...
The main aim of an ideal retrograde filling material is to seal the pathways of communication between surrounding tissues and the root canal system , hence mineral trioxide aggregate (MTA ) which is a biocompatible and a nontoxic material was developed for dentistry. This material allows normal healing response due to the formation of new cementum and bone. Calcium and phosphorus are the main i...
introduction: the aim of the present investigation was to compare the efficacy of mineral trioxide aggregate (mta) and 0.2% chlorhexidine (chx) mixture to pure mta, as a pulp capping material. methods and materials: the pulp of 24 lateral incisors and canines from four dogs were exposed and capped either with mta or mta+0.2% chx. after 2 months the animals were sacrificed and the teeth were pre...
