The objective of this study was to measure and compare in vitro wear resistance of nine cements against human enamel cusps in glycerol media using UAB second generation wear machine (hit and slide). Six cements were dual cured polymer-based cements; total-etch: Variolink II (Ivoclar Vivadent), self-etch: Multilink Automix (Ivoclar Vivadent) and self-adhesives: Maxcem Elite (Kerr), RelyX Unicem 2 (3m ESPE), PANAVIA SA (Kuraray) and G-CEM LinkAce (GC America). Three cements were water-based chemical cured cements; Zinc-phosphate: Harvard Cement (Harvard) and resin modified glass ionomers cements: RelyX Luting Plus (3M ESPE) and GC FujiCEM 2 (GC America). Samples were scanned after wear testing using a non-contact 3D profilometer (PROSCAN2000) to determine wear volume and depth. 2-way ANOVA, separate 1-way ANOVA and Tukey/Kramer post-hoc tests (p¡Ãœ0.05) for the statistical significance. The only dual cured cement in this investigation that showed a statistical difference in the wear as function of the curing modes was Maxcem Elite. Resin cements showed higher wear resistance in this study than glass ionomer cements which showed higher wear resistance than zinc phosphate. There was a significant difference in two groups of the dual cured cements of this study (G-CEM LinkAce, PANAVIA SA and RelyX Unicem 2) showed higher wear resistance than (Maxcem Elite, Multilink Automix and Variolink II).
