Abstract

The results of the research of the 3.8 impacted teeth’s enamel’s mineral component and its organic matrix with the help of electron and atomic force microscopy are studied. It has been stated that 15-20-year-olds have insufficient maturity of the tooth enamel, expressed in a less dense packing of the mineral component, a large proportion of the organic matrix, significant sizes of the prismatic shell, roughness and projections on the surface of enamel prisms. After 20 years, the amount of organic matrix decreases and the mineral prisms harden and increase in size. The presented facts indicate the critical role of the interconnection between the mineral component and the organic matrix in the tooth enamel’s firmness, the importance of which increases after the tooth eruption.

Key words:

mineral component, organic matrix, maturation, atomic force microscopy
