Functional features of tissue blood flow in the mucosa of the palatoalveolar complex

The prevention of periodontal diseases is one of the most important issues in modern dentistry due to their widespread prevalence and multifactorial nature. The transition to personalized medicine in the Russian Federation implies the development of individualized preventive measures based on the characteristics of each patient, particularly the individual constitutional features of the maxillofacial region. Aim. To study the functional state of the vascular system of the palato-alveolar complex mucosa in individuals with different configurations of the palatal vault using the method of high-frequency Doppler ultrasound (HFUS). Materil and methods. Using HFUS, the hemodynamics in the mucosa of the hard palate around teeth 1.7, 1.6, 1.5,1.4,1.3, 2.3, 2.4, 2.5, 2.6, 2.7 was assessed in 69 patients aged 21-25 years (first period of adulthood) with clinically healthy periodontium and without comorbidities. The subjects were divided into 3 groups according to their palatal vault type. A statistical analysis of the obtained data was carried out. Results. Qualitative analysis of Doppler ultrasound scans showed variability in the pattern of the color spectrum of integral blood flow in patients with different types of palatal vault. A high variability of the Vas (28.73% variability) and Qas (29.16% variability) indicators was revealed, which corresponds to the variability of the morphometric parameters of the hard palate. Conclusions. The data obtained demonstrate the high screening potential of the HFUS method for personalized diagnosis and prevention of dental diseases.
