Abstract

The effects of Porphyromonas gingivalis culture supernatant from strain W50, its avirulent variant (W50/BE1) and sterile BM culture medium on the morphological changes in polymorphonuclear leucocytes (PMN) from 10 patients with periodontitis (3 juvenile periodontitis, 7 rapidly progressive peri-. odontitis) were compared with those from 10 healthycontrols. Large non-polar cells (>160 mu m(2)) were increased in patients to 182.8% (p =0.0076) and 245.5% (p =0.0002) of control values with W50 and W50/BE1 supernatant respectively. In contrast, numbers of small non-polar cells (<80 mu m(2)) and polarised cells were decreased in the patient group. Patient/control ratios for small non-polar cellswere 30.3% (p =0.0007) and 33.6% (p =0.0005) with W50 and W50/BE1, respectively, and 38.2% (p =0.0147) for polarised cells exposed to W50 supernatant. The data indicate that PMN from patients with periodontitis differ significantly from those of healthy controls in the shape changes which occur after exposure to P. gingivalis culture supernatant.
