Solubility, porosity and fluid uptake of calcium silicate-based cements
(Univ Sao Paulo Fac Odontologia Bauru, 2018-01-01)
Objective: To evaluate the absorption/fluid uptake, solubility and porosity of White mineral trioxide aggregate (MTA) Angelus, Biodentine (BIO), and zinc oxide-eugenol (ZOE). Material and Methods: Solubility was evaluated ...
Influences of the insertion method in glass ionomer cement porosity
(Wiley-Blackwell, 2012-05-01)
The aim of this study was to evaluate the presence of porosities inside the glass ionomer cement (GIC) after different techniques of material insertion. MATERIAL and METHOD: Specimens were prepared with high-viscosity GIC ...
Porosity measurement of solid pharmaceutical dosage forms by gamma-ray transmission
(Pergamon-Elsevier B.V. Ltd, 2010-12-01)
The aim of the present work is the determination of porosity in tablets by using the gamma-ray transmission technique Tablet dissolution depends on some inherent characteristics of the manufacturing process, such as ...
Three-dimensional porosity characterization in carbon/glass fiber epoxy hybrid composites
(2019-10-01)
The main objective of this study is to analyze the effect of the stacking sequence of glass/carbon-reinforced hybrid composites on the impregnation quality and on the formation of voids. This was achieved by creating a ...
Measurement of Interfacial Porosity at the Acrylic Resin/Denture Tooth Interface
(Wiley-Blackwell, 2010-01-01)
Purpose: Small pores of almost uniform shape and size are common in polymeric materials; however, significant porosity can weaken a denture base resin and promote staining, harboring of organisms such as Candida albicans, ...
