Knowledge of the composition of an incorporated alloy is a precondition for avoiding polymetallism in subsequent prosthetic treatment, or detection of the cause of an allergic reaction attributed to a metallic component of the prosthesis restoration. The method proposed in this paper can be a very useful means of determining the presence of Ni–Cr or Co–Cr dental alloys, and, especially, beryllium in Ni–Cr alloys which, despite its toxicity, gives the alloy desirable properties. Nickel is also a well-known allergen. This paper reports an analytical procedure for detection and identification of cobalt-and nickel-based dental alloy components. The method involves anodic sampling, and separation and identification of the components by thin-layer chromatography on precoated microcrystalline cellulose layers. Computer-assisted optimization was used to choose the mobile-phase composition. Excellent detection and identification of nickel, chromium, cobalt, molybdenum, and beryllium, on the basis of different RF values and spot colors, was achieved after anodic sampling in-situ.

Microanodic dissolution of dental alloys enables intra-oral, in-situ, and almost non-destructive sampling of a permanent prosthesis restoration.
