The aim of this study was to evaluate the effectiveness of the proposed differential drug correction in generalized periodontitis of the II and III severity degrees depending on the initial state of the body's response in the short term.
 Material and methods. We examined 216 people aged 45 to 55 years with a diagnosis of generalized periodontitis. Depending on the state of the body's reactivity, patients were divided into three groups with normal, hyperand hyporeactivity. All patients received comprehensive conventional treatment. After surgery, the proposed differential drug correction was additionally performed. The effectiveness of the treatment was monitored by cytological and clinical examination on days 2, 4 and 6.
 Research results and their discussion. The results of the evaluation of the effectiveness of the complex treatment of generalized periodontitis of II and III severity in the short term showed that the proposed differential drug correction in the postoperative period optimizes the wound healing process by bringing the phases of the cellular reaction periods closer to those of normal body reactivity in terms of duration and intensity. Namely: the period of initial degenerative changes (1st day), the period of intense inflammation with active granulocyte and macrophage reactions (4th day) and the period of increasing reparative processes (6th day). The results of the cytological study are complemented and confirmed by the corresponding dynamics of clinical parameters, characterized by their normalization during differential drug correction.
 Conclusion. In patients with generalized periodontitis with hyperand hyporeactivity of the body, the proposed differential drug correction leads to normalization of the periods of cellular reaction during postoperative wound healing and clinical parameters in the short term.
