    The purpose of the study was clinical and laboratory analysis of the remineralizing properties and clinical efficacy of the course application of the Sensodyne Rapid Relief therapeutic and prophylactic toothpaste for sensitive teeth with tin fluoride. The study involved 50 overwise healthy patients aged from 18 to 25 years diagnosed with a localized form of hyperesthesia of hard dental tissues and no signs of acute inflammation of periodontal tissues. After 7 days of clinical observation and daily use of the toothpaste the hygienic condition of the oral cavity in all patients improved: oral hygiene index was 1.02Β±0.2 units; gum inflammation index (PMA) - 8.0Β±1.5%; the absence of hyperesthesia was diagnosed (1 point, p≀0.05). Examination of patients after 14 and 28 days confirmed the absence of pain in 100%, the organoleptic properties of the toothpaste under investigation were also highly appreciated by the participants. A laboratory study showed that patients have an increase in the pH value of mixed saliva and a decrease in its buffer capacity by 13.4Β±2.25%, which contributes to a more effective remineralizing effect of calcium ions by calcium-binding proteins of mixed saliva. The concentration of fluoride ions in the saliva of patients of both groups increased by average rate of 34Β±0.5% per week. The combination of tin and fluoride is more effective than fluoride alone. The presence of tin ions causes a higher ability of fluorides to bind with calcium ions on the surface of the dentin and dentinal tubules, inhibits the process of demineralization, enhances the additive interaction of the ions forming the acid-resistant layer on the surface of the dentin and dentinal tubules, leading to a decrease in hyperesthesia of the teeth.ЦСль исслСдования - ΠΊΠ»ΠΈΠ½ΠΈΠΊΠΎ-Π»Π°Π±ΠΎΡ€Π°Ρ‚ΠΎΡ€Π½Ρ‹ΠΉ Π°Π½Π°Π»ΠΈΠ· Ρ€Π΅ΠΌΠΈΠ½Π΅Ρ€Π°Π»ΠΈΠ·ΡƒΡŽΡ‰ΠΈΡ… свойств ΠΈ клиничСской эффСктивности курсового примСнСния Π»Π΅Ρ‡Π΅Π±Π½ΠΎ-профилактичСской Π·ΡƒΠ±Π½ΠΎΠΉ пасты Sensodyne ΠœΠ³Π½ΠΎΠ²Π΅Π½Π½Ρ‹ΠΉ Π­Ρ„Ρ„Π΅ΠΊΡ‚ для Ρ‡ΡƒΠ²ΡΡ‚Π²ΠΈΡ‚Π΅Π»ΡŒΠ½Ρ‹Ρ… Π·ΡƒΠ±ΠΎΠ² с Ρ„Ρ‚ΠΎΡ€ΠΈΠ΄ΠΎΠΌ ΠΎΠ»ΠΎΠ²Π°.

    Background. The population with HIV-infection plays significant role in ongoing tuberculosis pandemic. Immunosuppression due to HIV-infection is one of the causes of TB disseminated forms in this group of people. Having low immune status is also often associated with a polyclonal M. tuberculosis infection. Aim of the research: comparative assessment of epidemic genotypes of M. tuberculosis prevalence and mixed genotypes identification within HlV-TB co-infected patients in two Russian regions. Materials and methods. The DNAs of 78 clinical isolates from Irkutsk Region (IR) and 64 strains from Perm Krai (PK) have been genotyped by MIRU VNTR 24 and RD105/RD207. Strains were obtained from patients who did not have significant age and sex differences. In the PK age of the patients was 34.5 Β± 0.9, in IR - 34.4 Β± 1.5 years. The samples were obtained from 67.2 and 65.4 % of men, respectively. Result. The study of the M. tuberculosis indicates significant predominance of Beijing genotype strains in patients with TB-HIV of PK (92.2 %) compared to the IR (59.5 %) (Ρ…2 = 18.0; p < 0.01). The prevalence of MDR pathogens in TB-HIV patients exceeded 50 %. The mixed genotype detection in the PK and IR was high (14.1 and 12.7 % respectively). The level of virulent strains B0/W148 was 34.4 % in PK patients and 25.3 % in IR ones. Analysis of the results suggests the epidemic spread of MDR-TB in the immunocompromised individuals. Conclusions: The identified trends may indicate that Perm Kray have a process of active dissemination of transmissible strains of M. tuberculosis within HIV-infected population
