Features of basic indicators of oral fluid in children after hematopoietic cell transplantation (pilot study)
Abstract
Relevance. Treatment of patients with refractory forms of acute lymphoblastic leukemia causes a number of complications from the organs and tissues of the oral cavity. It can be both early complications – cytotoxic reactions with the development of oral mucositis, and late, leading to a violation of the mineralization of hard tooth tissues, and to underdevelopment of the teeth. Oral fluid plays an important role in maintaining oral homeostasis. One of the most important functions that it performs is maintaining the physiological balance of the processes of re- and demineralization of tooth enamel. Since demineralization processes begin in childhood at higher pH values than in adults, when the hydrogen index decreases below 6.4, demineralization processes begin to prevail over remineralization, and the solubility of hydroxylapatite crystals which enamel consists of increases.The objective was to assess the basic indicators of oral fluid and oral hygiene indices in this group of patients.Methods and materials. During the examination of the oral cavity, the intensity of caries and hygiene indices were determined. For the study, oral fluid was collected, followed by determination of its viscosity and hydrogen index.Results. These patients showed a lower level of oral fluid hydrogen index and a lower level of oral hygiene compared to healthy children. In addition, during the study, it was found that there is a direct relationship between the pH of the oral fluid and the time elapsed since the hematopoietic cell transplantation.Conclusion. The detected changes are factors that predispose to an increase in the intensity of caries, and require early preventive measures.Authors declare no conflict of interest.The authors confirm that they respect the rights of the people participated in the study, including obtaining informed consent when it is necessary, and the rules of treatment of animals when they are used in the study.
