Abstract EN
The aim of this work was to characterize the initial wear kinetics of two different types of glass ionomer cement used in dentistry (the conventional glass ionomer cement and the resin-modified glass ionomer cement) under sliding friction after 28-day storing in distilled water or Ringer’s solution.
Sliding friction was applied through a pin-on-disk tribometer, in sphere-on-plane contact conditions, under 5 N normal load and 120 rotations per minute.
The test lasted 7500 cycles and replicas were performed at 2500, 5000 and 7500 cycles.
A profilometer was used to evaluate the wear volume.
Data were analysed using Student’s t-test at a significant level of 5%.
There is no statistical significant difference between the results obtained for a given material with the maturation media (P>0.05).
However, for a given maturation medium, there are significant statistical differences between the data obtained for the two materials at each measurement (P<0.0001).
The wear rates of both materials decrease continuously during the running-in period between 0 and 2500 cycles.
After 2500 cycles, the wear rate becomes constant and equal for both materials.
The resin matrix contained in the resin-modified glass ionomer cement weakens the tribological behaviour of this material.
