In the structure of this pathology, a special place is occupied by odontogenic inflammatory diseases and their complications against the background of reduced immunity due to recurrent respiratory infections in children (Zuev V. P. 1994; Kazimirsky V. A. ssoavt, 1996, Henderson, 1995; Henderson, Wilson, 1995, 1996, etc.). The course of odontogenic infection in children has a number of features due to the relative immaturity of the child's organs and tissues, imperfection of immunity, abundance of lymphatic tissue, the presence of anatomical and physiological features of the structure of teeth and jaws, ease of damage and increased permeability to microbes of natural protective barriers, etc. The results of numerous epidemiological studies indicate that, on average, every child suffers from 3 to 5 episodes of acute respiratory viral infectious diseases (ARVI) per year. The greatest incidence of acute respiratory infections is observed in young children, preschoolers and primary school children. Children of the first 3 years of life get SARS within a year 2-2. 5 times more often than children aged 10 years and older. Recurrent respiratory infections lead to violations of the functional state of the body, can cause a breakdown of adaptation and cause the development of chronic pathology [Klyuchnikov S. O. with savt., 2017].
