QUESTION Which combination of eugenol-free cement and temporary indirect restorative material offers the best adhesion to IDS? OBJECTIVE This in vitro research aims to gain more knowledge about which cement in combination with indirect restorative material can best be used to manufacture and cement indirect partial facilities when it comes to bond strength (N). METHODS Standardized preparations have been made in 120 KaVo elements and an IDS (Immediate Dentine Sealing) layer has been applied. Afterwards, these samples are randomly divided into 6 (n = 20) groups. For the groups 1 to 3 indirect provisions are made from Protemp (Plus, 3M, Minneapolis, United States). Group 4 to 6 are provided with indirect provisions from Structur 2 (SC-QM, VOCO, Cuxhaven, Denmark). Provisions of group 1 and 6 are cemented with Provicol (QM, Voco, Indian Land, United States), group 2 and 5 with Durelon (3M, Minneapolis, United States) and group 4 and 5 with Temp-bond (Kerr, Orange, United States). The samples were tested consecutively in a tensile tester to measure the tensile force (N) needed to detach or break the indirect provisions from the elements. RESULTS The mean tensile force (N) per group was as follows: 15.5 N (group 1), 4.8 N (group 2), 3.3 N (group 3), 4.7 N (group 4), 3 N (group 5) and 15 N (group 6). The data analysis of the various main effects (cement and crown material) and the interaction effect showed a significant difference. The main effect of cement showed a significant difference (p = 0.00). In groups 1 and 6 the same cement was used and these gave a greater adhesion strength than the other groups. No significant differences were found for the other main effect and the interaction effect. Furthermore, none of the indirect provisions were broken during the measurement. Each of the provision came loose in its entirety. The cement was the weakest link for each sample. The IDS did not loosen from the element in any of the samples. CONCLUSION In this in vitro study and setting it can be concluded that Provicol offers significantly higher adhesive strength between indirect provision and the applied IDS layer in comparison with the other two used cement systems, independently from the provisional crown material that was used.
