We studied the penetration depth of an antiseptic introduced in the dentin of the tooth by using various methods. An in vitro experiment was performed to determine effective parameters of ultraphonophoresis and electrophoresis, providing the maximum-diffusion antiseptic Decasan in the dentin of the tooth. Compared with the control, three physiotherapy sessions of the root canal significantly increased in-depth penetration in single-rooted teeth. The inclusion of Decasan in the endodontic treatment of patients with chronic apical periodontitis for drug processing the root canal irrigation system is effective because it promotes deep diffusion of antiseptic solution in dentinal tubules.

Background. The violation of the marginal tightness of composite restorations and the recurrence of the carious process remains relevant to this day, especially in persons with a decompensated form of caries activity. In this regard, of undoubted interest is the possibility of a wide preventive effect of individual oral hygiene products with a remineralizing effect, particularly those containing brushite crystals. Brushite crystals have unique adhesive properties and tropism to hydroxyapatite crystals on the enamel surface. The principal mechanism of action of the “RemarsGel” system is a chemical reaction that occurs when calcium nitrate from tube # 1 is mixed with ammonium hydrogen phosphate from tube # 2, as a result of which a brushite crystal is formed on the surface of the teeth. Material and methods. From a clinical point of view, this study compared the clinical efficacies of a standard prophylaxis program (using traditional fluoride-containing personal oral hygiene products) of carious recurrence in patients with a high degree of caries activity and a developed program for using a natural two-component complex to strengthen and remineralize RemarsGel enamel. The effectiveness of the applied technique was monitored using clinical research methods immediately after sanitation and 1, 12, and 36 months after it. Results. The high efficiency of brushite crystals was established in terms of preventing violations of the integrity of the enamel–composite joint, which has a direct and immediate effect on the recurrence of the carious process. A statistically significant difference in the Ryge criteria was found between group Nos. 1 and 2. These results were confirmed by scanning electron microscopy and statistical processing of the research results. Conclusion. A scientifically based indication of the intended use of the system must be added to the list of main indications for use — in the presence of a significant amount of adhesive restorations in the oral cavity, made using direct and indirect methods, especially with decompensate caries.

Aim. This study aims to increase the efficiency of the wound process in patients with odontogenic phlegmons of the maxillofacial region by using energotropic and antioxidant agents. Material and methods. The clinical study included 42 patients with odontogenic phlegmons of the maxillofacial region. The patients were divided into two groups: comparison group (patients received traditional treatment) and main group (patients received treatment with Cytoflavin in the treatment regimen). Results. In the main group, the appearance of the first granulations occurred 2.1 times faster (on average on the 3rd day) in comparison with the granulation tissue in patients of the comparison group. Signs of edge epithelialization of wounds appeared almost 3 days earlier (on average on the 6th day) in the main group than in the comparison group; on the 7th day, secondary sutures were already applied, which was 1.6 times faster than the same parameter group 2, clearly suggesting the acceleration of reparative processes. Conclusion. The dynamics of clinical manifestations indicates the comparative effectiveness of using Cytoflavin as part of complex therapy. This finding is confirmed by the accelerated terms of wound healing, the appearance of granulations, epithelialization of the wound edges, and the imposition of secondary sutures.

In the article contains and analyzes the material about the role of the general surgical school of the Imperial Tomsk University, famous graduates of the University and the Tomsk Dental Institute (Medical Institute) on the formation and development of maxillofacial surgery in Russia.

This study analyzed the role of Helicobacter pylori in the development of lesions of the oral mucosa and explored the relationship between the prevalence and intensity of periodontal disease and the stage, duration, and severity of gastrointestinal diseases associated with H. pylori infection. The newly identified factors of H. pylori pathogenicity that participate in the development of lesions of the oral mucosa in case of a body infection were also determined.

Introduction. After the application of a removable prosthesis, adaptation is one of the most difficult periods for the patient. This period is especially pronounced in the absence of experience in using a removable prosthesis or in the presence of general somatic pathology in parallel. Acquired defects of the maxillofacial area require restoration of anatomical areas of significant volume, and the problem of adaptation to replacement constructions has become significant. The adaptive ability of the patient and oral stereognosy are closely related. Tongue muscles stimulate brain activity to improve the adaptability to removable structures. In this study, a set of special adaptive exercises was developed to increase the synthetic activity of the cerebral cortex and improve adaptability to removable prostheses. Materials and methods. The study involved patients aged 44–75 years. All patients were divided into three groups: clinical control (30 people), group with acquired defects of the dentition of the maxilla (25 people), and group with acquired defects of the upper jaw after surgery (25 people). Patients in the clinical comparison group were scheduled for surgical treatment of the teeth and the imposition of immediate prostheses immediately after surgery. Immediate prostheses were made prior to surgery using a standard technique. Results. Patients of the main group with neoplasms of the maxillofacial region were planned to resect the maxilla and apply a resection prosthesis directly on the operating table. Manufacturing of resection shaping prostheses was carried out following the standard procedure. All patients underwent stereognostic testing, and the degree of the patient’s adaptive ability was determined. Depending on the assigned adaptive support, each group was divided into subgroups. Patients in the first subgroup were prescribed modernized functional training, and patients in the second subgroup received the main treatment without prescribing exercises. Conclusion. On the basis of the results of examination, treatment, and dynamic observation of groups of patients with acquired defects in the dentition, the adaptation support reduced the time of adaptation to new removable dentures. The results were confirmed by objective research through the stereognostic testing and subjective feelings of patients.
