RESUMO
The task to develop a mechanism for predicting the hemodynamic parameters values based on non-invasive hydrocuff technology of a pulse wave signal fixation is described in this study. The advantages and disadvantages of existing methods of recording the ripple curve are noted in the published materials. This study proposes a new hydrocuff method for hemodynamic parameters and blood pressure values measuring. A block diagram of the device being developed is presented. Algorithms for processing the pulse wave contour are presented. A neural network applying necessity for the multiparametric feature space formation is substantiated. The pulse wave contours obtained using hydrocuff technology of oscillation formation for various age groups are presented. According to preliminary estimates, by the moment of the dicrotic surge formation, it is possible to judge the ratio of the heart and blood vessels work, which makes it possible to form an expanded feature space of significant parameters based on neural network classifiers. This study presents the characteristics accounted for creating a database for training a neural network.

One of the reasons for early tooth loss in the population is dental caries and periodontal diseases. Programs for the prevention of these diseases and delivery of dental care are planned on the basis of a study of dental disease incidence in various groups of the population, including the disadvantaged groups. Russian medical care system is in dire need of socially-oriented assistance to various groups of the country's population. Patients with hearing impairments constitute one of the aforementioned groups. Creating a program for the prevention of dental diseases for people with hearing disabilities is one of the important tasks of dental care. Currently, there are several directions of dental disease prevention: use of fluoride-enriched toothpaste, fluoridation of drinking water, correction of daily rations using foods rich in natural fluorine or artificially enriched with fluorine, and the use of fluoride-containing food additives.
