“…Morphology of the PEO surfaces was studied by scanning electron microscopy (SEM) as described [4] using Hitachi S-3400N equipment (Tokyo, Japan) with an accelerating voltage of 15 kV. Detailed examination of the chosen samples was made using Phenom ProX microscope at an accelerating voltage of 15 kV.…”

“…The electrochemical parameters are chosen such that after the initial formation of a dielectric oxide layer, the applied voltage is high enough to break the dielectric barrier and to establish continuous generation of plasma sparks with consequent formation of relatively thick microporous oxide layers [3]. Modification of the PEO parameters such as voltage and current density, as well as quantitative and qualitative content of the bath electrolyte can lead to modifications in the morphology and elemental composition of the coating layers [4]. The PEO has already found many applications in technical and biomedical fields.…”

“…Components of the PEO bath electrolyte preferentially should form complexes in order to improve robustness of the PEO processing. We and others [16,4] showed that addition of ethylenediaminetetraacetic acid, a widely used chelating agent (ChA), can dramatically increase reproducibility of the PEO process. Nitrilotriacetic acid (NTA) is another widely used ChA.…”

Dental/osseous implants manufactured of titanium (Ti) have become a routine and affordable method in medical practice. To increase the overall safety and longtime stability of the implants further, the sophisticated approaches have been investigated in order to supply the implants with the bioactive surface layers. They have to serve two purposes: to increase the osseointegration capacity of the implants and to reduce the chances of bacterial growth and formation of bacterial biofilms leading to periimplantitis. Plasma electrolytic oxidation (PEO) is becoming a promising method to introduce functionalized surface layers on a metal substrate. Various PEO protocols have been suggested in order to achieve better biocompatibility of the dental implants and to increase their resistance to bacterial infections. It was also suggested that the PEO layers could increase resistance to corrosion on the surfaces of metallic implants. The dynamic processes running on the surface of Ti during the PEO processing still require efforts to fully understand the molecular mechanisms of the formation of hard and porous oxide surface layers. We and others have already shown that addition of a chelating agent to the bath electrolyte leads to better outcomes in the morphology and functional characteristics of the implants. Here we report in depth characterization of the PEO parameters and the produced PEO surface layers using the bath electrolyte containing another widely used chelating agent, nitrilotriacetic acid (NTA) along with potassium phosphate and calcium formate. The results will contribute to further understanding the mechanisms of the PEO process and to establishing routine protocols for commercial exploitation of the PEO method.

Cell aggregates that mimic in vivo cell–cell interactions are promising and powerful tools for tissue engineering. This study isolated a new, easily obtained, population of mesenchymal stem cells (MSCs) from rat hard palates named hard palatal‐derived mesenchymal stem cells (PMSCs). The PMSCs were positive for CD90, CD44, and CD29 and negative for CD34, CD45, and CD146. They exhibited clonogenicity, self‐renewal, migration, and multipotent differentiation capacities. Furthermore, this study fabricated scaffold‐free 3D aggregates using light‐controlled cell sheet technology and a serum‐free method. PMSC aggregates were successfully constructed with good viability. Transplantation of the PMSC aggregates and the PMSC aggregate‐implant complexes significantly enhanced bone formation and implant osseointegration in vivo, respectively. This new cell resource is easy to obtain and provides an alternative strategy for tissue engineering and regenerative medicine.
