This work was designed to study the influence of NO synthase donors and blockers on the morphological structure of the dental pulp and periodontal tissues in laboratory animals under stressful conditions. It was shown that L-arginine, a donor of NO synthase molecules, can slow down the development of stress-induced reactions and reduce the severity of morphofunctional changes in the dental pulp and periodontal tissues.

The authors present an experimentally-deduced rationale for the application of cell technologies to dental implantation. Autologous mesenchymal stem cells isolated from adipose tissue and differentiated towards osteogenesis are used to coat the implants. Their influence on the process of osteointegration is evaluated.

Clinical and cost-effectiveness analysis of different therapeutic modalities applied to treat 110 patients presenting with moderately severe chronic generalized periodontitis and concomitant type 2 diabetes mellitus. The data on the relationship between the treatment expenditures and clinical efficacy were used to substantiate the most cost-effective strategies for the management of periodontitis including removal of the pulp in the teeth with estimated grade 2 mobility.

Stomatological biofilms Diplen K and Diplen G were used to treat patients presenting with chronic generalized periodontitis. The most characteristic general and local features of this pathological condition associated with type 1 periodontopathogenic bacteria were identified. It was shown that Diplen biofilms applied in combination with antibiotics clindamycin and immunomodulator galavit substantially suppress inflammatory reactions; moreover, they appear to reduce alteration of periodontal tissues. At the same time, clindamycin slows down the development and invasion of microorganisms which leads to a significant decrease in the number of the most aggressive anaerobic bacteria or their complete elimination; also, it strengthens the positive effect of the combined treatment. The patients reported the improvement of the overall health and needed no additional therapy.

This article highlights the problem of optimization of the prevention and treatment of traumatic sinusitis in patients suffering zygomaxillary fractures. A method has been developed to manage this pathology with the use of a fixing instillator. The application of this device is shown to allow fixation of bone fragments to be performed simultaneously with fractional dialysis of the maxillary sinus using antiseptic preparations. The proposed method prevents the development of traumatic sinusitis. Its clinical efficiency was evaluated using multispiral computed tomography, microbiological and immunological tests.

The present article is devoted to the experience with the use of the CAD/CAM system in clinical practice. The topical problems of its application are discussed. A case of aesthetic teeth reconstruction with the help of the CAD/CAM system is described.

The methods for direct and indirect tooth restoration have recently found the increasingly extensive application in the general structure of stomatological care provided to the population. Meantime, the majority of the responders interviewed in the course of the present study turned out to be poorly aware of the modern techniques for direct and indirect aesthetic restoration of hard tooth tissues. This finding implies the necessity of enhanced attention to the problem in question at all levels of pre- and post-diploma education of doctor-stomatologists trained in this important (especially in the current context) field.

The authors present data concerning the prevalence and structure of dentofacial abnormalities in 200 children of indigenous peoples residing at the territory of Khabarovsk krai (territory). The study is based on the results of examination carried out in three groups of children: living in the city of Khabarovsk, different locations of the region, and Orphan Home No 1. Patients from the Orphan Home showed the highest prevalence of dentofacial abnormalities associated with frequent tooth extraction.

The authors studied the parameters of quality and effectiveness of the dentists on thrapeutical reception depending on a degree of loading of the dentists and introduction of algorithms of medical work. Two groups of the dentists were estimated depending on realization of dispensary measures. The items of information on the certain lacks of the work of the dentists are received depending on loading on reception.
