Abstract
Aim: This study measured the microhardness of a newly developed glasscarbomer dental filling material within the first 24 hours after setting andcompared it against that of two different glass ionomers, with and withoutheating during setting, and a resin-modified glass ionomer.Methodology: Six cavities were prepared on acrylic resin discs. PMMAblocks were randomly divided into six groups of six cylinders and eachcavity was filled with one of the tested materials according to their group.The groups were: Group1, Fuji Triage™ with heat; Group 2, GCP Glass Fill™;Group 3, Equia™ with heat; Group 4, Riva LC™; Group 5, Fuji Triage™; andGroup 6, Equia™. Microhardness was measured by the Vickers hardnessscale using a microindentation hardness tester at 2, 4, 6, 12 and 24 hoursafter initial setting of the materials.Results: Fuji Triage™ with heat applied during setting (Group 1) provedto be the hardest material, while Riva LC™ (Group 4) and GCP Glass Fill™(Group 2) were the softest. Heating the Fuji Triage™ during the initialsetting period significantly increased its physical strength after 24 hours.Conclusions: It was seen that microhardness of materials which used inour study was effected both time and heat.
