Evaluation of gingival microcirculation in localized periodontitis of traumatic etiology

Abstract

Relevance. The indispensable study of blood microcirculation of periodontal tissues in patients with localized periodontitis of traumatic etiology (LPTE) alongside with the assessment of the somatic status lets determine the degree of adaptive capacity of the organism. Laser Doppler flowmetry (LDF) allows noninvasively identify preclinical changes in the periodontal blood microcirculation and observe periodontal status at any treatment phase aiming at the confirmation of effectiveness of undertaken measures.Purpose. The objective of this work is to evaluate periodontal blood microcirculation in LPTE for existing latent vascular flow changes and adaptation features.Materials and methods. LDF measurements of periodontal blood microcirculation in 169 patients with mild and medium LPTE, conducted relaxed and with the use of functional cold test, were done.Results. A decrease in the number of functioning capillaries in periodontal tissues (expressed in a decrease of the integral index of microcirculation), a decrease in blood flow variability (σ-standard deviation) and the stress of the functioning of the regulatory blood microcirculation (Cv) were found. Due to outcomes, it was registered that in mild and medium severity LPTE, normal reaction of adaptation detected at 69.6% and 43.4% cases, respectively, in the remaining cases reaction of intense adaptation and unsatisfactory response adaptation (only if the moderate degree of LPTE) were fixed.Conclusion. Latent periodontal vascular flow changes and also adaptation characteristics are closely related with the somatic state of the body, in particular with the presence of cardiovascular disease in a group of patients.
