Background: This study was conducted to evaluate the efficiency of Resilon in achieving an adequate apical seal, and to compare it with Gutta-percha. Materials and Methods: Sixty single rooted human teeth were selected and decoronated at the cement-enamel junction. The teeth were sectioned such that 14 mm of the root length remained. Working length was established, and cleaning and shaping were...

Aim: Most endodontic sealers show antimicrobial activity before setting, but most of them also lose this ability after setting. Addition of an antibiotic may affect the properties of sealers such as sealing ability, setting time, and so on. The aim of this study was to assess whether the addition of antibiotics (amoxicillin, doxycycline, and clindamycin) improves the sealing ability of AH 26 se...

The lateral sealing ability of a normal fault is a major factor in creating hydrocarbon traps. Therefore, a methodology for assessing the sealing ability of faults in the siliciclastic sequences of subsidence basins has been established; moreover, by using this methodology, the uncertainty inherent in hydrocarbon exploration can be decreased. Moreover, the petrophysical properties of fault roc...

Introduction: Mineral trioxide aggregate (MTA) as an alternative material to gutta-percha for obturation of root canal in special cases has several drawbacks. The purpose of this study was to compare the apical sealing ability of a new MTA-based sealer versus MTA. Materials and Methods: A total of 36 canals of extracted maxillary central incisors were instrumented and randomly divided into 3...

introduction : proper apical seal and obturation density are essential to long-term success of root canal therapy (rct). the apical seal and density of lateral compaction techniques using stainless-steel and nickel-titanium spreaders and vertical compaction with beefill device were compared in this in vitro study. materials and methods: a total of 66 extracted maxillary central incisors were in...

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...

INTRODUCTION The purpose of this in vitro study was to evaluate the effect of calcium hydroxide, double and triple antibiotic paste on the sealing ability of mineral trioxide aggregate (MTA) apical plugs. METHODS AND MATERIALS A total of 90 extracted teeth with single canals were prepared and randomly divided into four experimental groups (n=20). Intra-canal medicaments were applied for 3 wee...

introduction: the purpose of this in-vitro study was to investigate the influence of the remaining calcium hydroxide (ch) as an intracanal dressing on the apical sealing ability of three endodontic sealers. materials and methods: sixty-six single and straight canals of recently extracted human permanent maxillary central incisors were used. all canals were prepared and sixty of them were random...

introduction: mineral trioxide aggregate (mta) as an alternative material to gutta-percha for obturation of root canal in special cases has several drawbacks. the purpose of this study was to compare the apical sealing ability of a new mta-based sealer versus mta. materials and methods: a total of 36 canals of extracted maxillary central incisors were instrumented and randomly divided into 3 ex...
