Experimental study of changes in the chemical composition of tooth enamel when using hydrogen peroxide as the main chemical component in professional bleaching

Abstract

Objective: The aim: To study changes in the chemical composition of the tooth enamel surface when using hydrogen peroxide as a chemical component of the whitening system in combination with professional oral hygiene. Patients and methods: Materials and methods: To achieve this goal, during the study, we studied the enamel of the teeth of the frontal area, which was removed for orthodontic and orthopedic indications. The age of the patients whose teeth were examined ranged from 18 to 44 years. In the experiment, we studied the chemical structure of enamel by a method thatcovered the selection of the study area, with the designation of areas for microanalysis, and subsequent elemental analysis in selected areas of the enamel. Results: Results and conclusions: Analyzing the results of this study, we can make assumptions about the impact of professional dental hygiene on the procedure of photo-whitening teeth based on 35% hydrogen peroxide gel and its subsequent impact on theother clinical indicators, which will depend on the characteristics of functional and structural resistance of the enamel.
