Aim:
Optimization of conservative treatment schemes for generalized periodontitis (GP) against the background of somatic pathology, depending on the indicators of the Community Periodontal Index of Treatment Needs (CPITN).

Material and methods:
CPITN was performed in 134 patients with GP against the background of various somatic pathologies and divided into main and comparison subgroups. Treatment scheme No. 1 was developed, including means for local and supportive therapy, and was used in the main subgroup 1 (CPITN ≤ 2). Scheme No. 2, developed for the main subgroup 2 (CPITN > 2), included drugs of local and general action. Clinical dynamics were assessed by the values of PMA and OHI-S indices before GP treatment, and 3, 6, and 12 months after treatment.

Results:
After 12 months, «stabilization» of the pathological process in the periodontal tissues was observed, with CPITN index values ≤ 2, in 82.76% of the main subgroup patients, which was 2 times higher than the indicators of the comparison subgroup – 40.74%, p<0.01. With CPITN index values > 2, «stabilization» of the pathological process in the periodontal tissues was noted in 68.18% of patients of the main subgroup, which was 4.6 times higher than the indicators of the comparison subgroup – 14.71%, p<0.01.

Conclusions:
GP treatment with CPITN index values ≤ 2 and > 2 points against the background of somatic pathology using the developed schemes contributed to the elimination of inflammation and improvement of oral hygiene, which was confirmed by the positive dynamics of index scores in the immediate and long-term follow-up.
