RESUMO

Biopsies were taken from a child with Down's syndrome and her sibling under experimental gingivitis conditions and analyzed with monoclonal antibodies. At first, plaque caused a shift from a predominance of T cells to a predominance of B cells. Later, a gradual increase of T cells and a looser arrangement of B cells were observed.
