The usage of the principle of optimal management, namely such effects on complicated forms, when the course of the disease is close to that of uncomplicated course of the disease is very promising in drug therapy of patients with generalized periodontitis.

The aim is to study the intensity and duration of the phases of wound healing of the mucosa after spontaneous periodontitis surgery accompanied by normo-, hyper- and hyporeactivity of the body by cytological examination of smear-imprints of wound exudate.

Materials and methods: The experiments were performed on 24 adult mongrel dogs divided into three equal groups. In the first group, drugs that disrupt the reactivity of the organism were not used (normoreactivity of the organism). In the second group, the animals were simulated a сondition of hyperreactivity, in the third group – the hyporeactivity of the organism. All the animals with spontaneous periodontitis underwent a patchwork surgery. In the period after surgery, cytological examination was performed on the 1st, 4th, 6th and 9th day of the experiment.

Results: It has been revealed that in cases of the normal reactivity of the organism the following periods of cellular reactions during the healing of the gums mucous membrane can be differentiated within the appropriate terms: the period of degenerative-inflammatory changes (1st day), active granulocyte-macrophage reaction (4th day), reparations (6th day) and the period of increase of reparative processes with a decrease in the overall cellular response (9th day).

Examination of smear-imprints after surgical treatment in animals with spontaneous periodontitis with hyper- and hyporeactivity of the body allowed to identify the same periods of cellular reactions during the healing of the gingival mucosa, as in cases of normoreaction with hyperreation.Tthe intensity and duration of the wound healing phases differed from those which are typical for normoreactivity of the body: granulocyte-macrophage reaction was more pronounced and lasted longer until the 6th day, so later only on the 9th day there were cellular signs of regeneration.

With hyporeaction, the intensity and duration of the wound healing phases differed from those which are typical for normoreactivity of the body: granulocyte reaction occurred later (only on the 6th day) and lasted longer, signs of active regeneration appeared later on the 9th day. Therefore, postoperative wound healing in animals with impaired body reactivity was delayed for 3-4 days.

Conclusions: Thus, direct medical correction with transforming intensity and duration of the phases of the wound process which are characteristic for impaired reactivity of the body into the phases which are typical for normoreaction is essential. It provides synchronization of necrotic and reparative processes and creates conditions for normal uncomplicated healing of periodontal soft tissues
