Effects of N-Vinylcaprolactam Containing Polyacids and Zirconia on Mechanical Properties of Commercial Glass Ionomer Cements
This study aimed to investigate the impact of N-vinylcaprolactam (NVC) and Nano-sized yttria-stabilized zirconia (YSZ), separately and simultaneously, on the mechanical properties of the commercial glass ionomer cements (GICs). Methods: The NVC is able to ameliorate the mechanical and surface properties of glass ionomers; however, its effect hasn’t been investigated in conjunc...
متن کاملImproving mechanical properties of glass ionomer cements with fluorhydroxyapatite nanoparticles
Glass ionomer cements show great potential as low cost, minimally invasive dental restorative materials. However, their use is limited by relatively poor mechanical properties, especially fracture toughness. One possibility for improving their fracture toughness is through the addition of fluorhydroxyapatite nanoparticles, which resemble the crystals found in tooth enamel. Hydroxyapatite and fl...
متن کاملThe effect of heat on the mechanical properties of glass ionomer cements.
AIM The objective of this study was to assess the effect of heat application on the mechanical properties of glass ionomer cements. MATERIALS AND METHODS STUDY DESIGN experimental design. The effect of heat on glass ionomer cements during their setting was evaluated by measuring compressive strength, flexural strength and microhardness. Moroever, temperature changes from one surface of the...
متن کاملEffect of green propolis addition to physical-mechanical properties of glass ionomer cements
OBJECTIVE This study investigated the mechanical properties of glass ionomer cements (GICs) combined with propolis as a natural antimicrobial substance. MATERIAL AND METHODS Typified green propolis, as an ethanolic extract (EEP) or in the lyophilized form (powder), was incorporated to specimens of Ketac Fil Plus, ChemFlex and Ketac Molar Easymix GICs. For each test, 8 specimens of each materi...
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...
