Objectives: The purpose of this research was to determine the effect of different surface treatments and aging on the bond strength of different temporary restorative materials with temporary cements. Methods: 252 temporary crown materials 2 mm thick with a 10 mm diameter were prepared. No surface treatment was administered to the control group. 4% hydrofluoric acid gel was administered to one of the other groups and sandblasted to the other. Two types of temporary cement were used. After a 5000-cycle thermal cycle was administered to half of the materials, cement bond strengths were measured. Results: It was found that the material used, the type of cement, the aging treatment, the material*aging treatment, and the material-cement interaction (p<0.001) were statistically very significant, the material*cement*aging treatment interaction (p<0.05) were significant, and the other interactions were insignificant (p>0.05). Conclusion: Within the limitations of this in vitro study, it was found that the tested cements and surface treatments could not be implemented for all materials tested. It was found that the cement bond strength increased significantly in the temporary crowns administered by sandblasting. In the case of long-term use of the temporary restoration tested by evaluating the simulation of the oral environment, the use of a sandblasting surface treatment may be appropriate. It may be said that polymethylmethacrylate temporary crowns obtained by the conventional method have better bonding with eugenol-containing cements.
