Clinical performance of glass-ionomer cements
Glass-ionomer cements were developed by Wilson and McLean at the Laboratory of the Government Chemist in England in 1965. They were a logical addition to the family of water-based dental cements, comprising silicate cement, zinc phosphate cement and zinc polycarboxylate cement. Since their commercial introduction, they are now available in essentially two types. ‘Conventional’ glass-ionomers co...
متن کاملStudy of two MTA cements
INTRODUCTION To determine and compare the pH, conductivity and calcium release of an experimental Portland cement (PE) consisting of trioxid mineral aggregate and a comercially available modified Portland cement (C.P.M.) after 1, 2, 3, 4, 8, 10, 15 and 30 days. MATERIAL AND METHODS Cements were mixed following the manufacturer's instructions, with a powder: liquid ratio of 3:1. Each cement wa...

15 صفحه اولNovel cements: low energy, low carbon cements
Sustainability and the UK cement industry Traditional Portland cement-based concrete provides the foundation for the built environment. Buildings constructed appropriately and imaginatively from this material can and do exhibit an impressive array of properties [1] especially those that have been designed to optimise the thermal mass of concrete [2]. This type of concrete building is expected t...
متن کاملComparative study of digital radiopacity of dental cements
Introduction: Radiopacity is a necessary property for luting cements . The aim of this study was to investigate the radiopacity of some luting dental cements used in prosthetic dentistry. Methods: Five disclike samples of each material (6 x 1 mm) were prepared from panavia F2.0(Pa), Chioce2 (Ch.2), Glass ionomer GC (GI GC), zinc phosphate Hoffmann’s (ZP hof), zinc polycarboxylate Hoffm...
