Abstract
The biological environment is crucial for the bioactivity of modern calcium-silicate cements. Most of the studies of the materials were performed under ideal conditions, which are difficult to achieve in clinical practice. The aim of this study was to evaluate the surface characteristics of MTA+ (PPH Cerkamed, Medical company, Polish) and Biodentine in PBS and blood environments with a non-contact 3D optical profilometer Materials and methods: Retrograde cavities were prepared on the root surfaces of freshly extracted teeth. The cavities were filled with MTA+ or Biodentine, and the samples were immersed in PBS or Blood and placed in an incubator for 28 days. The surface of each specimen was scanned using a 3D optical profilometer at three different time points (1, 3, and 28 days). Statistical calculations were carried out using IBM SPSS Statistics (v.25), and significance was fixed at p <0.05. Results: Both materials showed that blood contamination affects the roughness of their surface. Both materials placed in blood contaminated conditions show reduced and constant roughness during the reported time periods (p> 0.05). This study showed that the surface roughness of MTA+ and Biodentine was adversely affected by blood pollution.
