INTRODUCTION The aim of this in vitro study was to evaluate the bond strength of Photo-Activated Disinfection (PAD) system to dentin with different root canal sealers by using a push-out test design. MATERIALS AND METHODS A total of 30 extracted mandibular premolar teeth with single and straight roots were used. The crowns were removed and the root canals were prepared by using ProTaper rotar...
Materials and Methods: A total of 36 canals of extracted maxillary central incisors were instrumented and randomly divided into 3 experimental groups (n=10) and two negative and positive control groups (n=3). Lateral compaction technique was performed using AH26 sealer (group 1 or control), and MTA Fillapex (group 2). The canals in group 3 were filled using vertical compaction of MTA alone. Sea...
introduction: the aim of this study was to evaluate the retreatability of root canals obturated with gutta-percha (gp) and three different endodontic sealers [iroot sp (bioceramic sealer), mta fillapex (mta-based sealer) and ah-26 (epoxy resin-based sealer)] using the protaper universal retreatment (ptr) system. methods and materials: forty extracted single-rooted human teeth were prepared with...
Background. Further studies on the adhesion properties of MTA-based materials seem necessary due to their growing use in endodontic treatment. This research aimed to assess the effect of retreatment on the bond strength of MTA-based (MTA Fillapex) and epoxy resin-based (AH Plus) sealers. Methods. ProTaper rotary files were applied to prepare the root canals of 80 human mandibular premolars. The...
UNLABELLED Mineral Trioxide Aggregate (MTA) is a calcium silicate-based material. New sealers have been developed based on calcium silicate as MTA Fillapex and MTA Plus. OBJECTIVE The aim of this study was to evaluate biocompatibility and bioactivity of these two calcium silicate-based sealers in culture of human dental pulp cells (hDPCs). MATERIAL AND METHODS The cells were isolated from t...
Introduction: Optimal radiopacity is one of the properties required for a root canal sealer that helps the distinction between the sealer and surrounding anatomic structures and evaluation of the quality of root filling. So, the purpose of this study was to evaluate the radiopacity of six root canal sealers at different focal distances. Materials and Methods: In this in vitro study, six endodo...
BACKGROUND The aim of the present study was to compare in vitro the antimicrobial activity of different root canal sealers against Enterococcus faecalis, prior and subsequent to setting. MATERIAL AND METHODS Agar diffusion test (ADT) was used for evaluating the antibacterial activity of non-set sealer while the direct contact test (DCT) was used for after setting. RESULTS ADT: Except for To...
The aim of this study was to establish the degree of tooth crown staining by commonly used endodontic sealers. Crown discolorations by tooth canal sealers [AH Plus (Dentsply DeTrey Gmbh, Konstanz, Germany); Endofill (Produits Dentaires SA, Vevey, Switzerland); Apexit (Dentsply DeTrey Gmbh, Konstanz, Germany); and MTA Fillapex (Angelus, Londrina, Brazil)] were tested on extracted human premolars...
Background Recently a new generation of endodontic sealers has been developed based on calcium silicate as MTA Fillapex, Endoseal MTA, Total Fill BC Sealer, EndoSequence BC Sealer, iRoot SP, Endo CPM sealer, MTA-Angelus and ProRoot Endo Sealer. A review of literature was conducted to discuss the composition, physicochemical properties, and clinical perspectives of calcium silicate based sealers...
مقدمه: از مهم ترین ویژگی سیلرهای درمان ریشه، خاصیت زیست سازگاری آن ها می باشد. هدف از انجام این مطالعه، بررسی میزان سمیت سلولی سیلرهای adseal ، tgsealer ، ah 26 و mta fillapex به صورت آزمایشگاهی بر روی سلول های فیبروبلاست لثه ای انسانی بود. مواد و روش ها: در این مطالعه ی تجربی آزمایشگاهی سیلرها در دو حالت تازه تهیه شده و سفت شده مورد بررسی قرار گرفتند. جهت بررسی سمیت سلولی، هر کدام از نمونه ها ...
