Kovalenko V. Substantiation of the choice of filling material depending on the morphological features of the hard tissues of the teeth and the composition of the oral fluid

The dissertation is devoted to the clinical and laboratory substantiation of the differentiated approach to the choice of filling material, depending on structural features and macro, microelement composition of hard tissues of the teeth and oral fluid composition. Chipped teeth with the subsequent determination of the number of enamel prisms, dentin tubules, their diameter, and the thickness of the gaps between them are investigated. The chemical composition of the enamel and dentin of the teeth with carious process against the background of physiological and increased erosion was studied with the help of the conducted chemical research aimed at revealing the content of macro and microelements on the boundary of the enamel-filling material, dentin-filling material. As a filling material for the comparison groups, hybrid glass-ionomer cement of double-type hardening cement VITREMER (3M ESPE) and composite rheno-contrast material of CHARISMA (Heraeus Kulzer), which was used with adhesive systems of 5 and 7 generations, was used. Clinical evaluation of the condition of applied filling materials using adhesive systems of 5 and 7 generations in patients in experimental groups for 3, 6, and 12 months was performed according to USPHS (United States Public Health Service) (G. Ryge, 1980, 1981) and correlations were found. The indicators with indexes of hygiene, the state of oral liquid, types of microcrystallization. The correlation between viscosity of saliva, features of the condition of solid tissues in the study groups and the DMF index was proved. Clinically established the effectiveness of the use of photopolymer materials in combination with adhesive systems of 5 and 7 generations for the treatment of patients with chronic middle caries on the background of physiological dental rubbing.
