This publication presents the results of laboratory studies of the effects of temporary filling material based on hydroxyapatite and tricalcium phosphate on the adhesion in the root canal pins and pinlay core, fixed on the composite glass ionomer cements. It was revealed that a temporary application of paste in the channel does not affect the quality of the attachment strength of prosthetic used in post endodontic restoration of the tooth.

At the present stage of development of the basic tool for cutting of necrotic tissues and forming, a cavity in the treatment of dental caries remains a rotary tool. Since the main dental restoration technique is adhesive technology, the quality of the enamel and dentin adhesive surfaces plays a decisive role in the future as a treatment. In vitro, using scanning electron microscopy was studied impact complex of hard teeth tissues preparation components (type cutting tool drive, feed rate, etc.) on the microstructure of adhesive enamel and dentin surfaces. Modeled and rendered the most frequently committed errors by doctors at preparing dental hard tissues. Diamond tool in combination with the turbine drive has the most adverse effect on the microstructure of dentin. Inadequate selection of tungsten carbide tools leads to significant destruction of enamel prisms, which in turn is responsible for violations of the adhesion of filling materials and recurrent caries. Just complete an adequate combination of the above components of hard teeth tissues preparation provides the necessary condition of the adhesive surfaces and high-grade quality of the composite adhesion.

The article presents information about some pathological changes in periodontal tissues during experimental osteoporosis. The experiments were conducted on 8 three-year sheep, which have at different times after ovariectomy removed dentoalveolar segments in the region of incisors of the lower jaw. Pathological changes in periodontal animals in experimental osteoporosis were local manifestations of the general condition of the body that are typical of acute hypoxia mixed character. It was found that experimental osteoporosis in periodontal develop processes accompanied by acute circulatory disorders, which worsen the conditions of metabolism, which ultimately leads to destructive changes of argyrophilic and collagen fibrils, as well as individual nerve fibers. Studies have shown that these effects are reversible, and after 120 days to the fore the phenomenon of compensation in periodontal starting to recover basic histological structure. Prolonged hypoxia, as the main link in the pathogenesis of degenerative and inflammatory of forms of periodontal disease may be modified by the proven of efficiency pharmacological means. The detected changes at the osteoporosis models can be the basis for further study of the role of autologous mesenchymal stem cells and materials-matrices of various origins in optimizing the osseointegration process.

During long-term orthodontic treatment there are various complications associated with a reduction in the level of hygiene. The article is devoted to the study of the hygienic condition of the oral cavity and the level of dental education in dynamics in patients undergoing orthodontic treatment. The examination and questioning of 40 patients aged from 18 to 35 years with fixed orthodontic appliances. In patients after 12 months of use braces deteriorating hygienic condition of the oral cavity. Care should be taken to inform patients about the care products and hygiene items, and their rational use, depending on the timing of orthodontic treatment and dental status.

The present article is devoted to the study of clinical effectiveness of remineralizating agents on the basis of hydroxyapatite created by the departments of Pharmacy and Dentistry of ESBEI HE “Kuban State Medical University, Ministry of Health Care of Russia”. The new remedy remineralizating effect was evaluated in treating patients with enamel caries (stage of white spot) and compared with the drug “ Ftor Varnish” (produced by “Omega Dent”). Clinical efficacy was studied by TER-method, the vital staining of the teeth and a laser fluorescence of hard dental tissues with the “DiagnoDent” device. The results obtained have proved the remineralizing effect after gel-based hydroxyapatite application, which allows to recommend the proposed gel for remineralization of hard dental tissues for caries prevention and treatment in the stage of white spot. Therapeutic and prophylactic remedy was made in the form of white translucent gel, which eliminates the undesirable staining of the hard tissues, is easy to apply in a thin layer on the surface and fills microdefects

The study of dental indicators of quality of life and the psychoemotional status of patients with type 2 diabetes with the orthopedic treatment of partial removable acrylic prostheses was carried out. In the period from 2014 to 2016 it was, carried out examination and treatment of 68 patients with partial adentia 1 and 2 classes at Kennedy in age from 51 to 68 years. The main group (n = 32) consisted of patients with diabetes type 2 diabetes with a disease duration of 6,8±1,7 years and an average blood sugar level of 8,2 and 1,2 mmol/L. Control group (n=36) consisted of patients without somatic pathology, balanced by gender and age with at group of observation. All patients in the period of orthotic treatment were defined with situational and personal anxiety according to the test Charles D. Spielberger, state of hostility and aggression questionnaire by A. Bass-A. Durka, level of neurotic test L. I. Wasserman. Quality of life related to health was assessed by questionnaire MO SF-36, determination of the degree of influence stomatologic pathology on quality of life in the “Profile of the impact of dental health” OHIP-14 RU. In the result of the study it was established positive dynamics of studied parameters of diabetic patients with orthopedic treatment of partial removable acrylic prostheses, which suggests that the reconstruction of defects of the dentition reflects not only the fact of improving dental health, but also has a significant positive impact on psychological health and quality of life of these patients.

Currently, the state of public health in the Russian Federation and the CIS countries is characterized by negative natural growth, high mortality and disability. There is a decrease in specific gravity and a sharp increase in the number of chronic non-communicable diseases. With age, the proportion of people suffering from chronic non-communicable diseases increases significantly compared to the young. At the same time society is becoming a significant proportion of persons of elderly and senile age. In the current environment increases the importance of health services, which are not only curative but also preventive, sanogenic orientation and focused on helping individuals of older age groups.

The article analyzes the labor and cost of cermet dentures (in the framework of the cast hromkobalta) and CAD / CAM milled prosthesis with zirconium dioxide. Quantitative indicators of the complexity and cost of the structure. Installed proximity common indicators of labor input and cost of these prostheses and the difference in their structure.

In this article considered the current vision of the problem of the influence of dental status in patients on the occurrence and/or development of squamous cell carcinoma (SCC) of the mucous membrane of the mouth (MMOC). On the basis of the some studies have noted a relationship between low level of the oral hygiene and the sharp edges of the teeth or dentures and the risk of developing this disease. Also revealed a correlation between periodontal disease and the possible development of SCC MMOC that corresponds to the main prediction about the risk of the development of this pathology on the background of the effects of chronical infection in the oral cavity. Significant correlation between the presence of carious lesions and the risk of developing SCC MNOC in contrast, is not detected. But clearly expressed role in the development of the cancers are galvanism and precancerous diseases of the oral mucous membrane and the red border of the lips.
