Wear resistance of dual-cured resin luting agents.
OBJECTIVE
To evaluate the three-body wear resistance of five commercially available dual-cured resin-based composite luting agents compared both in a dry state and after water storage.


METHODS
Six specimens of each material were prepared and tested for three-body wear resistance in the ACTA wear machine for 250,000 cycles and the loss of material was measured with a profilometer. Material wear was measured under three conditions: dry storage, 6-month water storage, and 12-month water storage.


RESULTS
One-way and two-way ANOVA and Tukey's HSD test of multiple comparisons revealed significant differences in wear resistance. Water storage did not significantly affect the wear resistance of four of the five materials. The order of wear resistance was: Cosmedent Insure > Vivadent Dual-Cement > Kerr Porcelite Dual Cure > Jeneric/Pentron Optec Luting Cement > Chameleon Mirage FLC (P < or = 0.0001). The rank order of wear resistance could not be readily predicted when based solely on the manufacturers' reported physical specification data.
