Clinical-radiological study on the role of biostimulating materials in iatrogenic furcation lesions.
UNLABELLED Root perforation is an unwanted incident which may occur at any stage of endodontic treatment and can adversely affect tooth prognosis. AIM To compare the recovery rate after treatment of root perforations in the interradicular area of the molars, using two different materials: MTA and ceramic nanoparticles mineral cement DiaRoot BioAggregate, by a clinical-radiological and statist...
INTRODUCTION In apical surgery, after apicoectomy and retro-preparation of canal, a retrofil material is applied to seal the apical region of the root canal. Mineral trioxide aggregate (MTA) is the gold standard material for this purpose. Changing water/powder ratios of MTA affects its properties. The purpose of this in vitro study was to determine the effect of liquid/powder ratio of retrofil ...
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...
مقدمه ماده ایده آل پرکننده انتهای ریشه علاوه بر خواص فیزیکی مناسب باید دارای خواص آنتی باکتریال مناسب برعلیه میکروارگانیسم های موجود در سیستم کانال ریشه و خارج از کانال ریشه باشد. هدف از این مطالعه، مقایسه خاصیت ضد میکروبی ترکیب سوسپانسیون نانوسیلوربا دو سمان mta وnec می باشد. مواد و روش ها سمان های مورد استفاده در این مطالعه شامل proroot mta وnec و میکروارگانیسم های به کار رفته در این مطال...
OBJECTIVE Our goal of the study was to evaluate the antibacterial properties of endodontic sealers against the E. faecalis. MATERIALS AND METHODS Six millimeters wells were made for each material in all the preinoculated petri plates. Then, the petri plates were incubated for 24 h. The zones of inhibition appeared were measured, and the measurements were put to statistical analysis. RESULTS...
Purpose: This study sought to compare the elemental constitution, morphological characteristics, particle size distribution, biocompatibility, and mineralization potential of Ortho MTA (OMTA) and ProRoot MTA (PMTA). Materials and Methods: OMTA and PMTA were compared using energy-dispersive spectrometry, particle size analysis, and scanning electron microscopy. The biocompatibility and mineraliz...
OBJECTIVE The aim of the present study was to determine the release of arsenic from 2 gray Portland cements, a white Portland cement, and 2 MTAs (ProRoot and MTA-Angelus). STUDY DESIGN The materials were manipulated and placed in plastic tubes, and the tubes were immersed in glass flasks containing water with grade reagent, pH 5.0. After 3 and 168 h, the water in which the material had been i...
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 =...
The application of mineral trioxide aggregates (MTA) cement during the root canal obturation is gaining concern due to its bioactive characteristic to form an apatite in dentinal tubules. In this regard, this study was to assess the biomineralization of dentinal tubules following root canal obturation by using pozzolan-based (Pz-) MTA sealer cement (EndoSeal MTA, Maruchi). Sixty curved roots (m...
مقدمه و هدف: هدف از این مطالعه بررسی واکنش بافت پالپ دندانهای بالغ دائمی ملتهب گربه اعم از شدت التهاب پالپ، شدت واکنش های بافتی و تشکیل پل عاجی نسبت به mta و بیودنتین بعد از پالپوتومی سرویکال می باشد. مواد وروش ها: مطالعه ما روی 30 دندان نیش ماگزیلا و مندیبل بالغ از 10 گربه با میانگین وزنی 1.5 کیلو گرم و میانگین سنی 2 سال فاقد هرگونه بیماری سیستمیک انجام گرفت. پس از ایزولاسیون، وتهیه حفره دس...
