Abstract:

The aim of this study was to evaluate the push-out bond strength and surface microstructure of tricalcium silicate materials when set in the presence of fetal bovine serum: Biodentine®, Theracal® and mineral trioxide aggregate by manufacturer�??s instruction. The specimens were randomly divided into 2 groups (n=20) for each material and then incubated for 4 days at 37°C; control group were then measured by a universal testing machine and the surface morphology of each experimental group was analyzed by scanning electron microscope. Biodentine® and Theracal® showed higher push-out bond strength compared with mineral trioxide aggregate after exposure to fetal bovine serum. In conclusion, the push-out bond strengths of Biodentine® and Theracal® were higher than mineral trioxide aggregate when exposed to blood contamination. Therefore, it is supposed that the use of Biodentine® and Theracal® is appropriate in the presence of blood.
