The objective of this study was to compare the sealing ability of ActiV GP/glass ionomer (GI) sealer (Brasseler USA, Savannah, GA), Resilon/Epiphany (Pentron Clinical Technologies, Wallingford, CT), and gutta-percha (GP)/AH Plus (Dentsply Maillefer, Tulsa, OK). Seventy-three human single-rooted teeth were randomly divided into three test groups (20 canals each) and two control groups (5 positiv...

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...

This thesis extends DRM schemes which address the problem of unauthorized proprietary content sharing in home networks to address the problem of unauthorized confidential content sharing in organizations. In particular it focuses on how to achieve secure content sharing between employees in a group while limiting content leakage to unauthorized individuals outside the group. The thesis discusse...

We consider a transmit precoder design for the K-user multiple-input single-output (MISO) interference channel in which each transmitter is equipped with multiple transmit antennas and each receiver employs a single receive antenna. First, we derive a closed-form expression for a minimum mean-square error (MMSE) precoder and an alternative expression for a signal-to-leakage plus noise ratio (SL...

A low power content addressable memory is designed by the pre-comparison scheme, power gating and dual-VED techniques. With the pre-comparison scheme, it will reduce the discharging time and power consumption when the match line is mismatch. Furthermore, the techniques of power gating and dual VDD are applied to the pre-comparison CAM to reduce the leakage power. The size of the CAM array is ab...

Coronal restorations and posts can positively influence the long-term prognosis of teeth following root canal therapy. Final sealing the canal by placing an appropriate post and core will minimize leakage of oral fluids and bacteria into the periradicular area and is recommended as soon as possible after completion of root canal filling. Glass ionomer or MTA placed over the residual root canal ...

conclusions the bacterial isolates exhibited strong biofilm formation potential, while the extracts of acacia arabica significantly inhibited biofilm formation among the isolates and, therefore, could be executed in the development of cost-effective biofilm inhibitor medicines. results pseudomonas aeruginosa (kc417303-05), staphylococcus hemolyticus (kc417306), and staphylococcus hominis (kc417...
