Change organic acid levels in the oral fluid in the bleaching

Abstract

Relevance. In the world of dental practice, in order to achieve the maximum aesthetic result when correcting the changed color of the teeth, preference is given to conservative methods of treatment, which include various types of bleaching. Due to the fact that professional teeth whitening has become widespread in the world dental practice, scientifically grounded conclusions about its effectiveness and safety, obtained in experimental models in vitro and in vivo, are of great importance. Goal. Study of the influence of photochemical and chemical types of bleaching on the acid composition of oral fluid. Materials and methods. 36 patients were examined, which were divided into two groups of 18 people each. All the examinees before the bleaching procedure had professional hygiene of the oral cavity, sanation of the oral cavity (temporary restoration). Each of the two groups underwent biochemical examination of the oral fluid before and immediately after bleaching. Results. A significant reduction in the level of acetic acid was observed in relation to the norm in all patients before tooth whitening. In the results obtained after teeth whitening, in patients of both groups the level of oral fluid acids decreased sharply in relation to the norm, and also in relation to the results obtained before clarification. Conclusions. Teeth whitening with the help of systems with chemical and photochemical activation leads to a significant decrease in the level of acids in the oral fluid.
