The incidence of malignant tumors of the buccal mucosa and stages of carcinoma were analyzed in 565 primary patients for a period of 10 years. The study showed social and organization problems in the disease diagnosis: refusal of patients from medical consultation, unjustified omitting of examination of the oral cavity aimed at cancer detection during preventive examinations of the population and treatment of odontogenic diseases, erroneous interpretation of pathological changes in the buccal mucosa, unjustified long observation and treatment by non-oncological specialists, incompetence of physicians, etc. Approaches to optimization of diagnosis are outlined: improvement of the efficiency of preventive examinations by non-oncological specialists, specialized upgrading of dentists and increase of their professional responsibility, and early use of morphological methods of examination of pathological processes in the buccal mucosa.

Oral ulcer wounds are difficult to heal due to bacterial infections, persistent inflammatory responses, and excessive reactive oxygen species (ROS). Therefore, the elimination of bacteria, removal of ROS, and reduction of inflammation are prerequisites for the treatment of mouth ulcer wounds. In this study, oligomeric proanthocyanidins (OPC) and 3-(aminomethyl)phenylboronic acid-modified hyaluronic acid (HP) were used to form polymer gels through dynamic covalent borate bonds.
