M-BessudnovaN. O-VenigS. B-AtkinV. S-150220131718921072020Copyright © 2013, Eco-Vector2013Chemical element compositions of crystal-like formations observed on the etched dentine surface have been researched based on the EDX analysis. It has been shown that the basic elements formed the crystal formations are calcium, phosphorus and oxygen, which has made it possible to identify the crystals as calcium-phosphate combinations.dentinecalcium-phosphate crystalsenergy dispersive x-ray analysisscanning electron microscopyдентинкристаллы фосфата кальциярентгеноспектральный анализсканирующая электронная микроскопия[Elliot J.C.
