EXAMINATION INDICES OF THE STATE OF THE VEGETATIVE NERVOUS SYSTEM IN CASE OF PERIODONTAL DISEASES IN THE PATIENTS WITH AFFECTED CERVICAL INTERVERTEBRAL DISCS

Abstract

Rationale of the topic. There is a certain stable dependence between the state of periodontal tissues and general somatic diseases. In modern concepts of pathogenesis of the inflammatory and inflammatory-dystrophic periodontal diseases much attention is paid to the vegetative-vascular disorders. It is known that affection of cervical intervertebral discs is accompanied by affection of the vegetative nervous system. At present the evaluation of vegetative dysfunction manifestations according to A. Vein and determination of its regulatory mechanisms according to Kerdo and Hildebrant has become widespread. However, the use of these simple, safe and informative methods in the patients with periodontal diseases is not sufficiently covered in the special literature. Objective of this research: to study the state of the vegetative nervous system in case of periodontal diseases in the patients with affected cervical intervertebral discs. Materials and methods. To achieve the stated objective the dental examination of 74 patients with periodontal diseases and affected cervical intervertebral discs (ACID) and 40 apparently healthy persons of the control group aged from 36 up to 72 years was performed. 48 patients of the main group and 26 persons of the control group made up a group of the 2nd period of the maturity age, 26 patients and 14 persons, respectively, of the elderly age. Disorders of the vegetative nervous system were determined using the Vein Questionnaire for detection of vegetative changes. To evaluate the outcoming vegetative tone the Kerdo vegetation index (VI) was calculated. To analyze the intersystem cardiorespiratory correlation the Hildebrant ratio (correlation between the heart rate and the respiratory rate, per 1 minute) was calculated. Results of the study. In the patients with affected periodontal tissues and CID the significant increase of vegetative manifestations and high frequency of vegetative dysfunctions could be observed with the confidence level of 99-99,9%, as compared to apparently healthy people. That gave evidence of the vegetative regulation disorder of homeostasis and homeokinesis of the examined patients. In the vegetative innervation of the cardiovascular system of the persons of the 2nd period of the mature and elderly age the sympathetic tone prevailed over the parasympathetic one (in the patients' groups – 4,2 and 4,3 times as much, in the control groups – 1,6 and 1,5 times as much) that proved the diffuse and generalized effect of the influence and stressed the role of the so-called premorbid background (pathology of the cervical intervertebral discs) in the development of periodontal diseases. The revealed significant deviations in the intersystem correlations according to the Hildebrant ratio in case of periodontal diseases in the patients with ACID proved a high level of inconsistency in the activity of the visceral systems: the heart and respiratory ones. The revealed sympathicotonia in the groups of patients (in 60,4 and 65,4% of observations, respectively) proved prevailing of the sympathetic influences on the heart over such influences on the respiratory tract.
