The secret of longevity is not only in healthy lifestyle and genetics, but in the forehanded prevention of diseases. Nowadays the preservation of health is much more the patient’s responsibility. This mission can be realized only through the high level of patient’s awareness and treatment compliance. Oral cancer has one of the highest mortality rates among all malignancies worldwide. A gap in patient knowledge about oral cancer, specifically related to risk factors and signs and symptoms, is posited to be among the key modifiable factor contributing to high morbidity and mortality. The purpose of this study is to evaluate the oral cancer awareness among patients of the risk group (aged patients with chronic oral mucosal diseases). Results of the study showed the lack of oral cancer awareness among patients: the mean knowledge score for the risk factors – 3, 1 ± 1, 2 out of 8, 0, for the signs and symptoms – 4, 9 ± 1, 3 out of 12, 0. It was found that women had higher oncological awareness than men, as well as participants with high educational level, and patients with premalignant oral lesions (oral lichen planus, oral leukoplakia). Educational programs are essential for improvement of oral cancer awareness among population.

The purpose of the study is to improve the efficiency of the dental specialists training, as well as to identify their relationship to learning with the use of acrylic teeth and virtual simulators. The study included 55 students of the 5th year of the Dental Faculty of RUDN. The time spent for the preparation of I and II classes by Black was estimated. At the end of the cycle, it was revealed that when working on the virtual simulator the results were better. In addition, students were surveyed. Thus, the virtual simulator provides an innovative approach that allows creating with very high accuracy real tactile sensations and the sense of presence.

BACKGROUND: The loss of interdental gingival papillae or the presence of black triangles between the teeth is one of the important problems in aesthetic dentistry, along with the loss of teeth and violation of the integrity of the hard tissues of the tooth. These patients have aesthetic, phonetic disorders, and it is also possible that food gets stuck between the teeth, which causes discomfort in the oral cavity and leads to periodontal diseases. Currently, an increasing percentage of people with orthopedic structures have a recession of the interdental gum. To improve the predicted result, it is necessary to approach this problem in an interdisciplinary way. MATERIAL AND METHODS: The search for publications was conducted in four electronic databases: Pubmed, Google search, eLibrary and dissercat from 2006 to 2021. 157 full-text publications were analyzed, of which 40 publications were included in the systematic review. RESULTS: According to various studies, the restoration of the lost interdental papilla varies from 1.68 to 5 mm. Complete restoration of the interdental papilla occurs when using microsurgical methods of restoration of the interdental gum. The least injury to soft tissues leads to the best results and reduces the risk of complications. CONCLUSION: Restoration of the interdental papilla is a complex surgical manipulation where microsurgical instruments must be used. Any rupture or excessive injury of the isthmus of the interdental papilla leads to a violation of blood supply, which leads to necrosis of the graft and aesthetic dissatisfaction.
