BACKGROUND During orthodontic treatment, the various elements that constitute the fixed appliance undergo different processes. As a result of a change of the surface, elution/coverage of metals on the surface can be observed in the process of corrosion/passivation. MATERIAL AND METHODS Scanning electron microscopy with an energy-dispersive X-ray analytical system (SEM-EDX) was used to analyze...
Dentin-like tissue formation and biomineralization by multicellular human pulp cell spheres in vitro
INTRODUCTION Maintaining or regenerating a vital pulp is a preferable goal in current endodontic research. In this study, human dental pulp cell aggregates (spheres) were applied onto bovine and human root canal models to evaluate their potential use as pre-differentiated tissue units for dental pulp tissue regeneration. METHODS Human dental pulp cells (DPC) were derived from wisdom teeth, cu...
MADAM, Amalgam tattoo is the most common exogenous pigmentation of the oral mucosa; surprisingly, there are no reports of similar lesions on the skin. It is caused by traumatic implantation of amalgam fragments into the oral mucosa following dental treatment, particularly when amalgam fillings are removed with high-speed instruments. Amalgam tattoo occurs mostly in the gingiva and alveolar muco...
zno nanorods and nanoparticles have been easily prepared via the decomposition of two simple schiff base zinc (ii) complexes, namely (n,n'–disalicylalethylenediamine)zince(ii) and (n,n'–disalicylalphenylenediamine)zince(ii) under microwave irradiation. the decomposition products of the complexes were characterized by ft-ir, xrd, sem, edx and uv-visible spectroscopy. ft-ir, xrd and edx results ...
The hierarchical architecture of protective biological materials such as mineralized fish scales, gastropod shells, ram's horn, antlers, and turtle shells provides unique design principles with potentials for guiding the design of protective materials and systems in the future. Understanding the structure-property relationships for these material systems at the microscale and nanoscale where fa...
In this study, we demonstrate a one-pot mechanochemical synthesis of the nanocomposite composed of stannite Cu2FeSnS4 and rhodostannite Cu2FeSn3S8 nanocrystals using a planetary ball mill and elemental precursors (Cu, Fe, Sn, S). By this approach, unique nanostructures with interesting properties can be obtained. Methods of XRD, Raman spectroscopy, UV-Vis, nitrogen adsorption, SEM, EDX, HRTEM, ...
