Abstract

Purpose
The objective of this study was to investigate the impact of blood contamination on the compressive strength and surface morphology of both conventional and newly developed calcium silicate cements (CSCs).
Materials and Methods
Compressive strengths of Endocem MTA Premixed Regular (EMPR) and ProRoot MTA (PMTA) were assessed after immersion in fetal bovine serum (FBS), saline, and deionized water (DW). Surface morphology was examined using scanning electron microscopy (SEM).
Results
The compressive strength of EMPR samples immersed in FBS for both 1 and 7 days was significantly lower compared to those in saline and DW, with no significant differences between the saline and DW groups. The PMTA group exhibited the lowest compressive strength after 1 day in FBS, although it did not significantly differ from that of saline and DW groups. SEM images revealed significant differences in crystalline formation between FBS and the other experimental groups.
Conclusion
Minimizing blood contamination during vital pulp therapy (VPT) is crucial to ensure optimal CSC setting. PMTA may be preferred over EMPR for resisting high occlusal forces in the presence of blood contamination.
