Glass ionomer cement systems have become important dental restorative and luting materials for use in preschoolers, children and teenagers. These materials form chemical bonds to tooth structure, are biocompatible, release fluoride ions for uptake by enamel and dentin, and are able to take up fluoride ions from dentifrices, mouthwashes, and topically applied solutions. Unlike early glass ionome...

Glass ionomer (GI) sealants can be utilised when a resin-based sealant is indicated but cannot placed due to poor moisture control, resulting from either inadequate tooth eruption or patient co-operation. GI hydrophilic, making it more compatible with the oral environment. Another significant advantage of their action as fluoride reservoir, aiding in remineralisation enamel.

Introduction: The giomers are a family of dental materials that allow faster effect and better functional, esthetic mechanical properties. Objective: To analyze the restorative ability between giomer type II glass ionomer in class I cavities. Methodology: A mouth split design was carried out which 27 permanent molars ICDAS 4, 5 or 6 were filled with (14) (13), respectively, patients high medium...

Rational design of catalyst layers in a membrane electrode assembly (MEA) is crucial for achieving high-performance polymer electrolyte fuel cells. Establishing clear understanding the property (catalyst ink)–structure layer)–performance relationship lays foundation this rational design. In work, synergistic approach was taken to correlate ink formulation, microstructure layers, and resulting M...

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: In restorative dentistry, selecting the proper material is an important factor for clinical success. The objective of this study was clinical evaluation of survival time of three tooth color materials in primary anterior teeth. Methods: In this interventional clinical trial study, 94 deciduous anterior teeth (36 teeth in boys, 58 teeth in girls) belonging to 3-5 year old children ...

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...
