Abstract
Creep behavior of restorative materials is an important mechanical property. Indentation creep of 6 different composites was evaluated at ageing times of 15 min and 1 week using a Dynamic Ultra-Microhardness Tester. The influence of water on indentation creep was slso assessed. The results were as follows:
-
1.
All the composites showed creep and the amount of creep was different among the composites at 15min. and 1 week.
-
2.
Water absorption increased creep.
-
3.
All the materials showed a decrease in creep with time when stored in air.
-
4.
Under scanning probe microscopy, the ridges of the diamond triangular pyramid indenter were sharp and the three sides of indentation were bow-shaped toward the center of indentation.
