Clinical experience confirms the influence of sexual steroids on the period
ont under several clinical conditions. The mechanisms of the noticed effect
s are not all completely understood. In this paper, phagocytes from gingiva
l crevice fluid of 39 patients with different forms of periodontitis and 18
healthy persons without periodontal disease were examined. Phagocytic acti
vity was assessed in vitro. Simultaneously to phagocytic examination, 17 be
ta-estradiol or dienogest were added to the samples in different concentrat
ions, in order to see whether a difference existed between phagocytosis in
the presence or absence of sexual steroids. Phagocytosis was significantly
reduced in patients with periodontitis. It was found that phagocytosis was
raised significantly by 13% in the group with periodontal disease under the
influence of 17 beta-estradiol. The administration of dienogest did not ch
ange the phagocytosis capacity significantly, In the healthy group, neither
addition of 17 beta-estradiol nor addition of dienogest caused any differe
nce.
