The paper presents a morphometric study of the ultrastructure of gum capillary endoteliocytes under the conditions of titan nickelide experimental implantation and phytomineral complex application. Positive changes of the ultrastructure of the cells under study are associated with the protective and stimulating effects of the given phytomineral complex. The study results allow substantiation of the use of correctors for the optimization of dental implantation results.

Laboratory investigations performed by the authors, demonstrate that dental bleaching using Opus Wheite laser system with 15 to 300 sec diode laser irradiation significantly influence micromechanical dental enamel characteristics, and leads to an increase in dental enamel microhardness, concerning both intact and pulpless teeth. The study shows that laser irradiation during 120 sec or more (up to 300 sec) results in a more stable increase in dental enamel microhardness. Fifteen to 60-sec irradiation led to an increase in dental enamel microhardness by 10.68 ± 1.04 % (P < 0.001) on the average, while 120 to 300 sec irradiation led to an increase in this parameter by 26.03 ± 1.36 %. Increase of dental enamel microhardness during diode laser bleaching suggests that irradiation results in the consolidation of the crystal matrix of the superficial dental enamel hydroxilapatite which increases dental acid- and caries-resistance.

Russian endodonto-endoosseous implants have advantage over similar foreign ones in their geometry, which provides better tooth fixation and allows more sparing osteotomy, and their cost.

The article covers the aspects of complex radodiagnostics of combined injuries of facial cranial bones and orbital structures. The effectiveness of various radiological diagnostic methods of the evaluation of maxillofacial structures is illustrated by sizeable clinical material. The authors demonstrate high information value of spiral computed tomography vs. other methods in revealing of bony lesions and foreign bodies, as well as diagnostics of pathology of orbital structures. The study established the diagnostic parameters of eye ultrasonography in patients with combined trauma of facial bones and orbital structures aimed at diagnostics of retinal detachment, hemophtalmus, and prevention of severe complications associated with these conditions.

The study established that the effectiveness of caries prevention significantly decreases in children on apparatus treatment due to the development of immunodeficiency. The patients, to whom caries preventive measures were applied, were divided into two groups: with and without immunocorection (1С). After 4 years of apparatus treatment, the intensity of caries in children without 1С increased 8.6 times, while in children who received 1С according to the offered regimen, this parameter increased 2.9 times. The study demonstrates that 1С in children with maxillodental anomalies and deformations, performed 5 and 15 months after bracket fixation, allows a 2-fold increase in caries prevention effectiveness.
