RESUMO
Extracted teeth were studied in patients with hypothyroidism, by applying electron and atomic force microscopy. This method allows one to have extended morphometric characteristics. The patients with hypothyroidism were found to have superficial and internal changes in the enamel, dentin, and cement of intact and carious teeth. The macro- and microelement composition of teeth were investigated. In hypothyroidism, the resistance of dental tissue depends on the homogeneous structure of enamel and dentin.

The objective drawbacks of most common methods of patient examination and treatment planning that determine certain percentage of unavoidable complications are outlined. In order to increase treatment efficacy with dental implants, updated examination methods and algorithm of their application were developed providing clear indications to bone-plastic operations and dental implantation, low number of complications and improved treatment results.

Hydroxyapol was used for intercanal-interosseous and intraosseous implantation. Operations were carried out in 62 patients with good results, this permitting the authors to recommend Hydroxyapol for practical implantations.

Hydroxyapol, a Russian biocomposite material, was used to repair defects of the jaw bones after resection of dental apices, cystectomy, and cystotomy in 102 patients. A more rapid formation of bone tissue and better stability of teeth were observed, in comparison with the patients treated traditionally, in whom the formation of a blood clot was the basis of osteointegration. Hydroxyapol is an effective means of osteogenesis, characterized by an anti-inflammatory effect.
