The dental specimens collected in the daily clinical working were analysed and inspected by the analytical electron microscope (ASID-S, KEVEX 5500). The materials were the metal bonding porcelain, amalgam filling teeth, carious teeth, dental calculi, salivary calculi and alveolar bone. The paper is aimed to show the principle of the present technique and its results of the elemental analysis. The reslults were summerized as follows. 1. The spot analysis of the dental calculi indicated the peak of the zinc which could suggest the foreign body. 2. The enamel substance filling the amalgam metal revealed the peak of the copper. These dental materials during the physical analysis warn of the causal genesis of the contamination of the daily dental work. 3. The hemispherical particles were found on the outer surface of the lamellate salivary calculi, whose spot analysis displayed similarities to the sruface analysis of the inner part of the salivary calculi.
