introduction: adequate root canal seal following retreatment is essential for a successful outcome. resilon/epiphany (r/e) obturation system has been introduced as a substitute for conventional gutta-percha/sealer method. this in vitro study compared the amount of apical microleakage of r/e with gutta-percha/ah26 (gp/ah26) sealer as secondary root canal filling following retreatment in human te...

The aim of the present study was to evaluate the bond strength (BS) of root canal fillings to root dentin using the reciprocating file-matched single-cone or lateral compaction techniques with resin-based and calcium-silicate-based sealers. Maxillary canine roots were prepared and filled using one of the following approaches: Reciproc R40 file and R40 single cone, WaveOne Large file and Large s...

OBJECTIVE The aim of this in vitro study was to evaluate the bond strength of different root canal sealers to dentin. MATERIAL AND METHODS Forty extracted single-rooted human teeth were examined and the coronal and middle thirds of the canals were prepared with a 1.50 mm post drill (FibreKor Post System, Pentron). The teeth were allocated in two experimental groups, irrigated with 2.5% NaOCl+...

INTRODUCTION The importance of perfect apical seal in endodontics, more specifically in periradicular surgery, is the motivation/reason for development of root-end filling materials with favorable physical, chemical and biological characteristics. The aim of this in vitro study was to evaluate the marginal adaptation of root-end filling materials using scanning electron microscopy. MATERIALS ...

Abstract After a spiritual epiphany, the Sakha shaman Alexander Gabyshev became prominent in 2018–2020 by calling Vladimir Putin an authoritarian demon. Critiquing Russia's corrupt society through internet and protest march, rose to civic leadership with multiethnic sympathizers. This article explains why popular, how he threat authorities, especially influential Russian Orthodox elites. Alexan...

INTRODUCTION Vertical root fracture inevitably leads to tooth extraction. Thus, root filling with obturating materials and sealers that can reinforce the tooth would be an ideal way to reduce fracture in root treated teeth. This study aimed to assess the fracture resistance of roots following the application of different sealers including Epiphany, iRoot sealer and AH-plus. METHODS AND MATERI...

This essay investigates ecological epiphany in short stories by Zadie Smith and Joyce Carol Oates, moments which characters confront the link between their own consumption habits planetary damage. These build on a longer literary history of modern fiction, that foregrounds suddenness, physicality, mundane, but these also adapt to address prominent concerns about anthropogenic climate change twe...

to eliminate microorganisms that are responsible for pulpal and periapical infections and to prevent reinfection of the root canal system an effective chemomechanical preparation by irrigants with sustained antimicrobial activity is beneficial. hereby, we evaluated the residual antibacterial activity of mtad after canal obturation at different time intervals.a total of 120 human single-canalled...
