FEATURES OF DENTINE CHEMICAL COMPOSITION OF INTACT TEETH AND TEETH WITH WEDGE-SHAPED DEFECTS.

Objective: The aim: Is to define dentine chemical composition of intact teeth and those with wedge-shaped defects followed by the analysis of revealed differences.

Patients And Methods: Materials and methods: Longitudinal sections of 22 clinically removed teeth (12 - clinically intact ones, 10 - with wedge-shaped defects) from both jaws were studied in patients aged between 25-54 years. JSM-6490 LV focused beam electron microscope (scanning) with system of energy-dispersive X-ray microanalysis INCA Penta FETх3 was used.

THE CORRELATION OF THE CHEMICAL COMPOSITION OF ENAMEL AND ORAL FLUID IN PATIENTS WITH A WEDGE-SHAPED DEFECT AND INTACT TEETH.

Aim - to determine oral fluid chemical composition and mineralization level in patients with a wedge-shaped defect and intact hard tissues, conduct correlation between the indicators of cervical enamel and oral fluid. We determined Сa2+, РО43-, SO42 using spectrophotometric method, Na+, К+, Al3+ by atomic emission spectrometry, Mg2+, Zn2+ by atomic absorption spectrometry, Cl- using chloride-selective electrode of pH-meter in oral fluid of 22 patients divided into two groups: case - with wedge-shaped defects (2.81+/- 0.
