PG  - 273-83
AB  - Scanning electron microscope (SEM) connected with X-ray microanalysis (EDX) was 
      used to study surface alterations of gold-coated brass dental pins (Dentatus), 
      taken out after some years from restored teeth due to necessity for repeating a 
      restorative therapy. The study method led to establish that: --the gold coating 
      of the base material, constituted of copper alloy, absolutely insufficient to 
      prevent corrosion attack; --the observed morphological alterations are the 
      consequence of a localized corrosion attack, produced by anaerobic bacteria, 
      which origin is confirmed by the presence of S on the most attacked points; 
      --finally the corrosive phenomenon does not cause a periapical pathology, but the 
      process is contrary, or rather, it is the pathology that leads to the favourable 
      conditions to create corrosion.
