Clinical study of treatment effectiveness of microcracks of teeth by the method of deep enamel fluoridation

Abstract

Introduction. The significant prevalence of microcracks in the enamel of permanent teeth requires the administration of therapeutic and preventive measures to avoid further progression. The width of their opening determined experimentally by the authors involves obturation of defects with microcrystals formed while using the system for deep fluoridation of enamel. Objectives. The purpose of the study was to identify the effectiveness of the system for deep fluoridation of enamel in the treatment of enamel microcracks in young patients in the near and distant terms. Materials and methods. In this regard 96 people (average age 22.84±5.46 years) were divided into four groups according to the number of groups depending on the presence of symptoms of dentin hypersensitivity and features of professional hygiene before using the system for deep fluoridation of enamel Ftorcalcit-E. The effectiveness of the prescribed treatment was evaluated based on the dynamics of the electroexcitability of the dental pulp and the electrical conductivity of the enamel, as well as the prevalence and intensity of dentin hypersensitivity indices. Results. Significant differences were found out in all groups according to research criteria compared to the initial state (p<0.01). The best results were obtained after the end of the second course of treatment a year later when there was determined a significant increase in the electrical excitability of the dental pulp and a more significant decrease in the electrical conductivity of the enamel even in comparison with the corresponding indicators after the first course of treatment (p<0.01). Clinical symptoms of dentin hypersensitivity completely disappeared, on average, in 90% of patients. Conclusions. The conducted analysis has showed that the peculiarities of professional hygiene affect the quality of the prescribed treatment. It has been proven to be more effective in the near and distant periods of observation after the previous removal of the dental biofilm by the method of air-abrasive cleaning with AIR-FLOW device using a powder based on erythritol. The authors recommend Ftorcalcit-E as a remineralizing therapy for patients both with tooth enamel microcracks and clinical symptoms of dentin hypersensitivity for long-term use once a year.
