OBJECTIVE This study was aimed to evaluate and to compare the push-out bond strength of different brands of mineral trioxide aggregate (MTA) with a calcium enriched mixture cement (CEM). MATERIALS AND METHODS Fifteen extracted, single-rooted human teeth were used. The middle-third of the roots were sliced perpendicular to the long axis into 1.00 ± 0.05 mm thick serial slices (15 root × 4 slic...
سابقه و هدف: پرفوراسیون از دلایل مهم شکست درمانهای اندودونتیک میباشد.در این میان پرفوراسیونهای فورکا پیش آگهی بدتری دارند. مواد مختلفی برای ترمیم غیر جراحی پرفوریشنهای فورکا پیشنهاد شده کهMTA یکی از آنها میباشد. با توجه به عوارض پرفوراسیون فورکا در مولرهای شیری و با توجه به این مسأله که تمامی مطالعات در زمینه مولرهای دائمی میباشند، انجام این مطالعه در دندانهای شیری ضروری به نظر میرسد. ب...
BACKGROUND Mineral trioxide aggregate, or MTA, is a new material developed for endodontics that appears to be a significant improvement over other materials for procedures in bone. It is the first restorative material that consistently allows for the overgrowth of cementum, and it may facilitate the regeneration of the periodontal ligament. CASE DESCRIPTION The authors present five cases in w...
INTRODUCTION The provision of an effective apical seal is an essential factor when choosing an appropriate material for success of root-end surgeries. Root-end resection, preparation and obturation should provide an adequate apical seal. The aim of this in vitro study was to investigate bacterial and dye microleakage of four different root-end filling materials and compare the efficacy of these...
Introduction. The aim of this study was to compare MTA with another base material, IRM, which is generally used on pulpal floor after root canal treatment, regarding their effect on the success of root canal treatment of primary teeth with furcation lesions. Materials and Methods. Fifty primary teeth with furcation lesions were divided into 2 groups. Following root canal treatment, the pulpal f...
This study evaluated the root-end sealing ability of mineral trioxide aggregate (MTA Angelus), reinforced zinc oxide-eugenol cement (Super EBA), resin-modified glass ionomer (Vitremer) and zinc-free amalgam (GS-80) (control). The root canals of eighty human lower molars were accessed, cleansed, shaped and obturated. Apexes were resected and cavities were prepared. Teeth were divided into 4 grou...
Introduction: This study compared the apical sealing ability of a bioceramic based root canal repair filling material (iRoot FS) with mineral trioxide aggregate (MTA). Methods and materials: Forty single-canal teeth were prepared and randomly divided into two experimental groups (n=18) and two control groups (n=2). Teeth in experimental groups were retrofilled with either MTA or iRoot FS. After...
The effect of different storage solutions on surface topography of mineral trioxide aggregate (MTA) and new experimental cement (NEC) as root-end fillings was investigated. Twenty-four single-rooted teeth were cleaned, shaped and obturated in a same manner. After root-end resection, 3-mm deep root-end cavities were ultrasonically prepared. Samples were randomly divided into four test groups (A1...
Background and Aim: Sealing the root canal system is of great importance in endodontic treatment especially in infected teeth. Several materials have been introduced for this purpose. The aim of the present study was to evaluate the sealing ability of MTA as an orthograde root filling material and compare it with laterally condensed gutta-percha with sealer.Materials and Methods: Thirty-six ext...
background and aims. various materials and methods have been introduced for obturating cleaned and shaped root canal systems. this in vitro study aimed to evaluate the sealing ability of single-cone obturation technique with mineral tri-oxide aggregate and calcium-enriched mixture based on bacterial leakage approach. materials and methods. sixty-four single-canal teeth were prepared and randoml...
