Indicators of the functional state of the autonomic nervous system in different age group patients with temporomandibular joint pain dysfunction syndrome

Abstract

Aim. To study the functional state of the autonomic nervous system and of the adaptative capabilities of the organism in patients of different age groups with temporomandibular joint pain dysfunction syndrome. Methods. The study included 234 patients with temporomandibular joint pain dysfunction syndrome (22 men and 212 women) aged 12 to 35 years, without anomalies of the dentition, who were divided into three age groups. Three control groups consisted of 30 healthy subjects (3 men and 27 women, 10 men in each age group) with intact dentition, and orthognathic bite. A clinical dental examination, and a multi-dimensional verbal-color pain test were conducted. In order to assess the functional status of the autonomic nervous system and the adaptive capacity of the organism used were the schemes of examination for detecting signs of autonomic disorders, a physicians questionnaire «Study Design for detecting signs of autonomic disorders», an autonomic test - «Questionnaire for detecting signs of autonomic changes for the patient» and a questionnaire, adapted for children and adolescents, cardiointervalography. Results. In all 234 patients with temporomandibular joint pain dysfunction syndrome revealed were the signs of autonomic dysfunction, possessing vagotonic features in 93.9% of the cases. An unbalanced condition of the autonomic nervous system in association with the temporomandibular joint pain dysfunction syndrome was registered significantly (p 0.05) more frequently in patients of the mature age group. According to cardiointervalography, in the patients revealed was a primarily vagotonic or hypersympaticotinic type of response, a significant predominance (p 0.05) of the functional stress adaptation mechanisms, mismatch of the processes that control heart rhythm until the breakdown of the adaptation mechanism. Conclusion. The revealed instability of the autonomic regulation and the features of autonomic responses in patients of different age groups with the temporomandibular joint pain dysfunction syndrome are necessary to consider when developing and selecting methods of pathogenetic therapy.
