Study of hard tissues of the tooth crown using scanning electron microscopy and elemental analysis

The introduction of new methodological approaches actualizes research that makes it possible to establish relationships between the elemental composition of hard dental tissues and microscopic analysis data. Using scanning electron microscopy, the nature of the location and size of enamel prisms was revealed, and a description of the structure of the initial and final enamel was given. The zone of the dentino-enamel junction, the location of the dentinal tubules and the composition of the dentin matrix were studied. It has been proven that the content of water, organic matter, sodium and potassium is higher in dentin, and the concentration of magnesium, phosphorus and calcium is higher in enamel.
