Abstract
Aim: To evaluate the microshear bond strength of MDP-containing versus MDP-free bonding systems. Materials and Methods: 48 dentin rods were obtained from extracted teeth. Which were divided into two equal groups according to the type of bonding system (G): MDP free bonding system (G1), MDP containing bonding system (G2) (n=24). Each group was further subdivided into three subgroups according to storage time (T): immediate (T1), 3 months (T2), and 6 months (T3). The micro-bonding strength is tested by a universal testing machine. The results were statistically evaluated using the Shapiro-Wilk test, Levene’s test, and post-hoc tests. Results: For specimens tested (T1), (G1) showed a non-significant lower mean shear bond strength value (12.18 ± 4.42) than (G2) (13.80 ± 4.61). (p-value=0.49). (T2), (G1) showed a non-significant higher mean shear bond strength value (10.79 ± 2.98) than (G2) (10.74 ± 4.59). (p-value=0.98). (T3), (G1) showed significantly higher mean shear bond strength values (8.61 ± 3.16) than (G2) (2.46 ± 0.95). (p-value =0.001). Conclusions: The adhesive procedure has a more effective impact on the final bond strength performance of restorations than the incorporation of MDP molecules.
