ABSTRACT

OBJECTIVE: The aim of the study is comparative analysis of the condition of oral organs and tissues in people with metabolic syndrome (MS) of varying severity before orthopedic dental rehabilitation based on dental implants. MATERIAL AND METHODS: 255 patients (151 women and 104 men) aged from 35 to 65 years were examined. 3 groups were formed 2 study groups and a comparison group. Groups 1 and 2 included individuals with excess body weight and MS. The control group consisted of 88 people without MS. An index assessment of the condition of the periodontium and tissue structures of the alveolar bone (according to cone-beam computed tomography), microcirculation in the gingival mucosa was carried out using laser Doppler flowmetry. RESULTS: The analysis of the periodontal condition indicators showed that in all groups of patients with MS, periodontal pathology occurred, the value of which was significantly higher than in patients of the control group (p <0.05). The analysis of bone tissue according to CBCT data showed that the most favorable conditions (type 1 and type 2 of bone according to Misch) for dental implantation are found in people without MS, respectively 3.5% and 35.1% of cases. The intensity of blood flow (σ) was 21.2% lower in group 1 and 48% in group 2, compared with the control group. Vasomotor activity (Kv) was 13.2% lower in the first group and 35% lower in the second group. A decrease in amplitudes in the area of all rhythms in the LDF gram was found low-frequency - by 15.6%, high-frequency - by 16.9%, pulse - by 3.6%. CONCLUSION: Changes occurring in the organs and tissues of the mouth against the background of MS of varying severity lead to a decrease in tissue perfusion with blood and blood flow activity, a local decrease in bone density, and as a result, pathological changes in periodontal tissues. Before performing dental rehabilitation, it is necessary to take into account all the risks of possible complications caused by the general condition of organs and systems of people with MS.
