Pathophysiological aspects of dental hyperesthesia and ways to eliminate it in elderly patients after a new coronavirus infection COVID-19

Currently, there is no scientifically substantiated information on the occurrence of dental hyperesthesia and its causes in patients who have undergone a new coronavirus infection COVID-19. Objective: to study the occurrence of dental hyperesthesia, to analyze the causes and to find ways to eliminate it in elderly patients after a new coronavirus infection COVID-19. Material and methods. The incidence of dental hyperesthesia was studied in 175 elderly people (from 61 to 75 years old) who had a new coronavirus infection COVID-19 2-4 months ago. As a control group, 125 elderly people were examined, who had not suffered from a new COVID-19 coronavirus infection before their examination. Functional resistance of hard tissues of teeth was assessed using the index of enamel resistance test (TER-test) according to V.R. Okushko and oral hygiene using the simplified index of oral hygiene of Green-Vermillion OHI-S. Results. It has been established that in the postcovid period, dental hyperesthesia is more common in elderly patients, the cause of which is the demineralization of tooth enamel due to the deterioration of individual oral hygiene. Generally accepted oral hygiene in elderly people suffering from dental hyperesthesia contributes to the normalization of the TER-test indicators with a period of 3 to 6 months of regular dental and oral care. The additional use of remineralizing ASEPTА gel for teeth by patients during dental care made it possible to achieve high structural and functional resistance of tooth enamel during the quarter. Conclusion. In people who have undergone a new coronavirus infection COVID-19, due to the deterioration of the hygienic condition of the oral cavity, there is a decrease in the mineralization of hard tooth tissues, which is a factor in the occurrence of dental hyperesthesia and confirms the crystal chemical theory of this pathology. The additional use of remineralizing ASEPTА dental gel for individual dental and oral care makes it possible to achieve high caries resistance of tooth enamel in a shorter time.
