The study was done to assess the sealing ability and adaptation of RealSeal 1, and to compare it with Thermafil. 65 single-rooted extracted teeth were selected and root canal treatment was performed. Root canals were obturated with RealSeal 1 or Thermafil. A double chamber bacterial leakage model using E. faecalis was developed to assess the sealing ability. Samples were monitored daily for 60 ...

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...

PURPOSE This study was conducted to evaluate micro-leakage through different furcation repair dental materials which are used to repair iatrogenic perforations in teeth. Six commercially available dental materials high copper amalgam, glass ionomer cements (GIC) Fuji II and Fuji IX, intermediate restorative material (IRM), mineral trioxide aggregate (MTA) and fully injectable calcium phosphate ...

This paper describes the influences of the threshold voltage VT on the leakage behavior of the dice after a fabrication process. By measuring the current consumption (leakage) on a CMOS cryptographic device like smartcard security controller and using the DPA analysis it is possible to make the key visible which is used during a cryptographic operation. Therefore, in this paper not only the sec...

Observations have been made in 17 normotensive subjects selected from the wards of the Third (New York University) Medical Division of Bellevue Hospital. Included in this report are observations made on 4 additional subjects reported in a previous communication (2). The total group comprises 19 female and 2 male subjects between the ages of 20 and 68 years. All subjects were maintained on the r...

IDDQ test is a valuable test method for semiconductor manufacturers. However, its effectiveness is reduced for deep sub-micron technology chips due to rising background leakage. Current two test methods that promise to extend the life of IDDQ test are Current Ratio and Delta-IDDQ. Although several studies have been reported on these methods, their effectiveness in detecting defects has not been...
