Gutta-percha (G) and sealer do not resist coronal leakage. In this study, the effect of orifice plugs using dentin-bonding/composite resin(C) or IRM on coronal leakage was evaluated in vivo. Sixty-one premolar roots in three beagle dogs were instrumented and filled with G and AH 26(S), or G alone. The coronal 2 mm was replaced with C or IRM, or left untreated. The access cavities were kept open...
A regularity model-based multiobjective estimation of distribution algorithm (RM-MEDA) has been proposed for solving continuous multiobjective optimization problems with variable linkages. RM-MEDA is a kind of estimation of distribution algorithms and, therefore, modeling plays a critical role. In RM-MEDA, the population is split into several clusters to build the model. Moreover, the fixed num...
introduction: this in vitro study compared the apical sealing ability of three common root end filling materials namely mineral trioxide aggregate (mta), intermediate restorative material (irm) and calcium-enriched mixture (cem) cement using a bacterial leakage model. methods and materials: the study was conducted on 83 single-rooted human teeth. tooth crowns were cut and root canals were p...
This paper demonstrates a methodology to help practitioners maximise the utility of complex multidisciplinary engineering models implemented as spreadsheets, an area presenting unique challenges. As motivation we investigate the expanding use of Integrated Resource Management (IRM) models which assess the sustainability of urban masterplan designs. IRM models reflect the inherent complexity of ...
This article introduces a novel family of decentralised caching policies, applicable to wireless networks with finite storage at the edge-nodes (stations). These policies, that are based on the Least-Recently-Used replacement principle, are here referred to as spatial multi-LRU. They update cache inventories in a way that provides content diversity to users who are covered by, and thus have acc...
AIM The aim of this study was to evaluate the minimum bactericidal concentrations (MBC) of root-end filling materials ProRoot MTA, MTA Angelus and IRM. MATERIALS AND METHODS Macrodilution broth method was used. Microorganisms used were: Staphylococcus aureus (ATCC 29213), Enterococcus faecalis (ATCC 29212) and Streptococcus mutans. Serial two-fold dilutions of root-end filling samples were pr...
The increasing dependence of South Asian countries on international remittances (IRM) and tourism development (ITR) in the presence political uncertainties has attracted scholars' attention. Although largest receiver IRM, Asia fails to channel these funds industry, which continues operate below its potential. This study estimates impact stability (PS), their interaction with foreign direct inve...
La Bili-IRM est une méthode diagnostique d’introduction relativement récente dans l’arsenal d’exploration de la pathologie bilio-pancréatique. Il s’agit d’une technique fiable reproductible et non invasive, permettant la visualisation directe des voies biliaires et pancréatiques. Le but de ce travail était d’étudier les aspects morphologiques des principales anomalies et d’évaluer la place de l...
