Bond Strength Evaluations of a New Universal Adhesive

Objectives: The advantages of universal adhesives are the application-multi-modality and adhesion to different substrates.
To compare the “universal” character of a new Universal Bonding (IBUN, Heraeus Kulzer) to two other universal adhesives using shear (SBS) and microtensile (µTBS) bond strength on different substrates and in different application-modes.
Methods: Tested adhesives were iBUN, Scotchbond Universal Adhesive (SUA, 3M ESPE) and All-Bond Universal (ABU, Bisco). Adhesives were applied according IFU in a self-etch or etch&rinse mode on human dentine and enamel (n=8/group). Adhesives were used in self-etch mode on precious metal (Bio Maingold SG), non-precious metal (Heraenium CE) and zirconia (HeraCeram Zirconia, all Heraeus Kulzer). Specimens (n=5/group) were alumina-sandblasted (1.5 bar) prior adhesive application. Venus Diamond (A2, Heraeus Kulzer) was filled in plastic molds and cured for 20s. Adhesive and composite were cured separately. SBS was determined after 24h water storage at 37°C. Non-tooth-specimens were additionally thermo-cycled (5000 cycles, 5-55°C).
µTBS: Occlusal dentine of human molars was exposed and polished. Adhesives were applied according IFU. Composite was applied and teeth were stored in water for 24h. Specimens were sectioned to obtain sticks for µTBS.
ANOVA and LSD post-hoc tests for the comparison of the adhesives were done. Independent t-Test was used between application-modes of each adhesive. (p<0.05).
Results: See results in tables.
Conclusions: iBUN can be used successfully in self-etch and etch&rinse-mode on all tested surfaces (tooth, metal, zirconia).
