INTRODUCTION Propylene glycol (PG) improves the handling, physical, and chemical properties of mineral trioxide aggregate (MTA). This study aimed to evaluate the effect of PG on the sealing ability of MTA and calcium-enriched mixture (CEM) apical barriers. METHODS AND MATERIALS A total of 70 extracted human maxillary single-rooted teeth were prepared using ProTaper rotary system. The apical 3...

Integrating tools implemented as plug-ins is a complex and time-consuming activity that requires good programming skills and a deep understanding of the underlying plug-in architecture for successful completion. Even when tools are implemented as plug-ins for a same integrated development environment (IDE), users frequently prefer to manually perform the same inefficient operations every time t...

Effects of some important parameters like impactor effects, plug geometry and initiation points on bonding aluminum tubes to aluminum plugs were studied. The impact velocity and dynamic angle between tube and plug should be precisely managed to achieve an optimum bonding condition. A new explosive bonding technique with the use of two material impactors was proposed. Results are especially suit...

introduction : the aim of this study was to examine and compare the apical sealing ability of ah26, ah plus and ah plus jet using a fluid filtration model. materials and methods : 70 single-rooted teeth were dissected from the cement-enamel junction. canals were prepared with protaper rotary system and manual k files and irrigated with 5.25% naocl and 17% edta. ten teeth were assigned as contro...

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...

Background: Management of the necrotic immature permanent incisor has long been a difficult clinical problem. The Frank technique of multiple applications of calcium hydroxide, although often successful, required multiple appointments and could take years to complete. More recently, the single-appointment mineral trioxide aggregate (MTA) apical plug technique reduced the multiple appointments t...

instrument breakage during treatment can lead to serious complications and carries the risk of treatment failure. when a file breaks in the canal, bypassing or removal can be difficult and the long-term prognosis of the tooth may be compromised. sometimes surgery may be indicated for removal of the broken segment. often some part of the root cannot be cleaned because of blockage by the broken f...

More and more security vulnerabilities were found in network softwares nowadays, making network security assessment one of the most important tasks for IT administrators. Vulnerability scanner is the key application for fulfilling such tasks. However, large numbers of vulnerabilities result in even larger number of vulnerability plug-ins including common plug-ins and specific plug-ins, which ma...

A numerical framework for modelling platelet plug dynamics is presented in this work. It consists of an extension of a biochemical and plug growth model with a solid mechanics model for the plug coupled with a fluid-structure interaction model for the blood flow-plug system. The platelet plug is treated as a neo-Hookean elastic solid, of which the implementation is based on an updated Lagrangia...
