[Serum's immunoglobulins in dental caries with or not dental alloy].

In 51 individuals with dental caries (mean age +/- SE, 30, 12 +/- 1, 43) were determined the serum's immunoglobulins IgA, IgG, IgM and the ration IgG/IgA. The levels of them were compared with the levels of immunoglobulins of 53 individuals (mean age +/- SE 36, 78 +/- 1, 86) with no significant difference (p greater than 0.1).
