Anatomoclinical and bacteriological study on chronic marginal periodontal disease. Therapy with staphylococcic...

Histological, histochemical and electronmicroscopic investigations were carried out on gum biopsies taken from cases with chronic marginal periodontal disease before and after the treatment with staphylococcic vaccine, thus, morphopathologically proving the findings of Gafar et al. (1985) and of Georgescu et al. (1973; 1974; 1975; 1979; 1995). Before treatment, gum lesions were severe, consisting in an abundance of polymorphic inflammatory infiltrates in the chorion along with oedema and disorganised connective fibres, atrophies and ulceration of the mucosa, purulent deposits at the surface with bacteria and fungi. After the treatment with the staphylococcic vaccine, an epithelial regeneration was seen together with the absence of the chronic inflammation. The intensely fibroparius granulated tissue was also noted, in all cases observing abundant connective fibres, accounting for good results after treatment, notably the firmness of the tooth fitting.
