Features of clinical course and treatment principles of endodontic-periodontal lesions

Aim. To study the characteristic differences in the clinical course of chronic generalized periodontitis in the presence of periapical infection focus and the principles of combined treatment of endodontium and periodontium.

Methods. A clinical and X-ray examination of 1525 patients of different age groups was performed. As a result, a clinical group of 68 patients with chronic generalized moderate and severe periodontitis was formed, who were divided into two groups depending on the presence or absence of periapical destruction. In group 1, 32 patients with the presence of chronic generalized periodontitis and signs of chronic apical periodontitis were united. Group 2 included 36 patients with chronic generalized periodontitis and no periapical infection and damage. The index estimation of the periodontal tissues state in the dynamics of combined endodontic and periodontal treatment was performed.

Results. The initial task of treating endodontic periodontal lesions, regardless of the localization of the primary lesion focus, is the elimination or reversal of chronic periapical inflammatory processes of the teeth. The proposed monitoring system in the course of treatment and dynamic follow-up for 18 months for patients suffering from endodontic periodontal lesions using clinical and radiological methods of examination involves: (1) interim epicrisis or conclusion about negative or positive compliance 1-2 months after the completion of endodontic treatment and hygiene procedures; (2) periodontal treatment (according to indications) with the assessment of clinical efficacy 6 and 12 months after the start of treatment; (3) epicrisis after 18 months.

Conclusion. The use of proposed concept of complex treatment of endodontic-periodontal lesions, monitoring system in the course of dental therapeutic and preventive measures and dynamic follow-up for 18 months allows achieving positive compliance in 85% of patients according to the clinical examination and in 80% of patients according to radiologic examination.
