Microhardness and Wear Resistance of Glass Ionomer Cements Modified by Chitosan and Nano-Hydroxyapatite
Despite the merits of glass ionomer cements (GICs), they suffer from weak mechanical properties such as low wear resistance. In this study, the mechanical properties of GICs after incorporating chitosan and nano-hydroxyapatite was investigated. The samples were prepared in four groups, including non-modified GIGs (NMGIC, n = 5), chitosan incorporated GICs (CHGIC, n = 5), nano-hydroxyapatite inc...
متن کاملEffect of Light Curing Unit on Resin-modified Glass-ionomer Cements: a Microhardness Assessment
OBJECTIVE To evaluate the microhardness of resin-modified glass-ionomer cements (RMGICs) photoactivated with a blue light-emitting diode (LED) curing light. MATERIAL AND METHODS Thirty specimens were distributed in 3 groups: Fuji II LC Improved/GC (RM1), Vitremer/3M ESPE (RM2) and Filtek Z250/3M ESPE (RM3). Two commercial light-curing units were used to polymerize the materials: LED/Ultrablue...
متن کاملThe Effect of Nano-filled Resin Coating on Fluoride Release in a New Conventional Glass Ionomer Cement
The objective of this study was to evaluate fluoride release amounts and patterns from high strength tooth filling material (EQUIATM) which is a conventional Glass Ionomer Cement, and investigate whether the application of nano-filled resin-based coating with different thicknesses has any effect on fluoride release from this new material. A total of 120 disc shaped specimens (10 x 2 mm) of EQUI...
متن کاملGlass ionomer cements.
Glass ionomer cements have been used in pediatric restorative dentistry for 20 years. Their usefulness in pediatric restorative dentistry is preferential relative to other materials because of their fluoride release, chemical adhesion to tooth structure, and availability to use in a variety of clinical scenarios. This paper reviews the use of glass ionomer materials in pediatric restorative den...
