   Abstract:	Owing to the ample dental market supply, more than a thousand different systems and alloys for prosthetic use are presently available. The aim of the study was to identify the basic components of the existent prosthetic constructions in patients requiring additional prosthetic therapy. Anodic sampling of eight prosthetic restorations of unknown composition was performed using a minielectrode with a graphite handpiece, aqueous NaCl solution as electrolyte, and a 4.5 V battery as a source of electric current. The samples were analyzed by quantitative thin-layer chromatography (QTLC). Sample chromatograms were developed by use of the acetone and 2 M HCl solvent system. Cobalt was visualized using aqueous solution of sodium-diethyldithiocarbonate, and chromium by ethanol solution of dimethylglyoxime. The percentage proportion of the elements identified was determined on an image analyzer, previously gauged according to the known standards.
