Dependence of regional circulation in periodontal tissues on the condition of occlusive-articulatory disorders in patients with chronic generalized periodontitis

Abstract

Abstract Introduction. The scientific substantiation of the causal relationships of traumatic occlusive forces and periodontal diseases is a difficult task and this issue is still debatable. According to available data, occlusive loads in the area of compression of periodontal ligaments lead to changes in blood circulation in lymphatic and blood vessels, which increase the inflammatory process when the adaptive capacity of the periodontal is exceeded. It is necessary to obtain additional information to choose tactics for reducing premature contacts in chronic generalized periodontitis. The aim of the study was to study the state of regional blood circulation in periodontal diseases with the elimination of occlusive obstacles by selective grinding of teeth. Results and discussion. 25 patients with occlusal interference before and after grinding were examined. In the study group, a decrease in the rheographic index by 41% and an increase in the time of rapid and slow blood filling by 1.5 and 1.6 times, respectively, before occlusive grinding were found. After the elimination of premature supracontacts, hemodynamic parameters changed in the opposite direction, the rheographic index increased, and the α1 and α2 indicators decreased. Other hemodynamic criteria studied approached the values in the comparison group. Conclusion. The results of the study confirm the expediency of minimally invasive interventions to eliminate occlusive interference in order to improve hemodynamics in periodontal tissues.
