Assessment of the pH value of the acid-base balance of the oral fluid in patients before the application of orthodontic devices, after three and six months of treatment with removable and non-removable equipment made of different materials

Hardware orthodontic treatment with intraoral devices made of various materials can contribute to the development of an imbalance of a number of chemical elements in the body, as well as their redistribution in the oral fluid. These changes affect the metabolic processes of both essential (vital) and toxic trace elements that can accumulate in the body, as well as affect the hydrogen pH of the oral fluid. Research objective. To investigate the hydrogen index of acid-base balance of oral fluid in patients before and during orthodontic treatment with various equipment in dynamics.
