Abstract
Aim: This study measured the microhardness of a newly developed glass
carbomer dental filling material within the first 24 hours after setting and
compared it against that of two different glass ionomers, with and without
heating during setting, and a resin-modified glass ionomer.
Methodology: Six cavities were prepared on acrylic resin discs. PMMA
blocks were randomly divided into six groups of six cylinders and each
cavity 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™; and
Group 6, Equia™. Microhardness was measured by the Vickers hardness
scale using a microindentation hardness tester at 2, 4, 6, 12 and 24 hours
after initial setting of the materials.
Results: Fuji Triage™ with heat applied during setting (Group 1) proved
to be the hardest material, while Riva LC™ (Group 4) and GCP Glass Fill™
(Group 2) were the softest. Heating the Fuji Triage™ during the initial
setting period significantly increased its physical strength after 24 hours.
Conclusions: It was seen that microhardness of materials which used in
our study was effected both time and heat.
