Abstract
: Dates of analyzes of chemical and mineral composition of hard tooth tissues and parameters of bone metabolism were evaluated in 70 patients with chronic generalized parodontite and 25 patients without parodontite. It is shown, that nonstoichiometric calcium-deficient carbon bearing hydroxyapatite is the main mineral component of the investigated dental hard tissues. The broad spectrum of microelements could be isomorphically included in crystalline structure of apatite of hard tooth tissues was detected. We find out decreased mineralization in mantle dentin. We checked decreased bone mineral density and changes in biochemical markers of bone mineralization.
