Abstract: Objective: The objective of this study was intended for evaluation the effect of different surface treatments on microtensile bond strength of two different luting resin cements to two CAD/CAM resin ceramic materials with dentin. Materials and Methods: A total number of 112 samples were used for microtensile bond strength test (µ-TBS). Samples were divided into two equal main groups according to type of resin ceramic used (Vita Enamic [ENA] and Lava Ultimate [LVU]). Then each main group was subdivided according to the surface treatment performed into four equal subgroups; Gr 1 (sandblasting (SB) with Al2O3 50µm), Gr 2(sandblasting (SB) with Al2O3 110µm), Gr 3 (plasma etching), and Gr 4 (Hydrofluoric acid (HF) plus Silane), then two types of resin cements (Rely X Ultimate, Panavia f 2.0) were applied to the treated ceramics in each group. µ-TBS test was performed and the data statistically analyzed. Results: The results of this study revealed that; LVU recorded statistically significant higher µ-TBS than ENA. Rely X Ultimate recorded statistically significant higher µ-TBS than Panavia F 2.0. Conclusion: LVU has higher µ-TBS than ENA with all surface treatments except with HF plus Silane ENA has higher µ-TBS than LVU. Key Words: Resin ceramic, Resin cement, sandblasting, Plasma, Hydrofluoric acid.
