The paper presents the results of an experimental study of morphological, functional and structural changes in the dentine around pulp chamber and in the pulp using combinations of pastes for treatment of early and acute pulpitis. An experimental study was performed on eight mongrel dogs aged 2 to 6 years. The experiment included 57 teeth: 12 canines, 45 premolars and molars. The entire volume of material was distributed on five series of experiments. It was found that the use of combination of developed medical pastes showed marked rapid restructuring the layers of dentine around pulp chamber and relief of the inflammatory reaction, the normalization of the main components of the pulp and significant increase in dentine genesis function of pulp

Endodontic preparation of permanent teeth with incomplete root formation is a time consuming process, which is determined by a number of anatomical features characteristic of this period of development. In this connection, the purpose of the study was to evaluate the performance impact of the most commonly used antiseptics against microbiota of root canals in permanent teeth with incomplete root formation in chronic apical periodontitis in children. Was a comparative characteristic of the efficacy of endodontic antiseptics, the most commonly used at the Junior dental examination used to reorganize the system of root canals in permanent teeth with incomplete root formation, «Miramistin», 2% chlorhexidine bigluconate, «Endotin» («Septodont») and «Belodez» («VladMiVa»). The positive changes in the species composition of the picture after the drug treatment of root canals.

The paper based on the analysis of the clinical picture 127 cases odontogenic maxillary sinusitis revealed the role of chronic periodontal lesions and periapical infection on the development of inflammation of the maxillary sinus in adults of all ages. The causes of odontogenic inflammation of the maxillary sinuses in the young, middle, old and senile, including traumatic maxillary sinusitis, which were the cause of perforation of the maxillary sinus during surgery or tooth extraction, pushing the root filling material in the maxillary sinus during endodontic treatment of teeth with complicated forms of tooth decay

The work is devoted to the evaluation of the effectiveness of apex-phoresis in the treatment of chronic apical periodontitis. The influence of apex-phoresis on the immune response periodontal segment is studied, terms of bone regeneration in areas of destruction are defined. As a result of immunological research it was found that the efficiency of the method of apex-phoresis was implemented in the redistribution of the structure of immune cells, increase in the number of neutrophils and lymphocytes. The increased phagocytosis activity, functional activity of neutrophils and erythrocytes was observed. The proposed method can reduce the quantity of complications and adverse outcomes, increase the percentage of positive results and shorten the time of treatment.

Failure to comply with the rules of personal hygiene can lead to dysfunctional results in the treatment of patients with orthopedic implant restorations. Using scanning electron microscopy and studied the nature of the bristles of toothbrushes structure at different times of operation. Consequently, the objective assessment of the hygiene tools and their clinical testing have both acquired great importance. To assess the oral hygiene before and after 3 months of use of various toothbrushes used several indices (Approximal Plaque-Index (API), the index Turesky (PI), a modified plaque index superstructure Silness-Loe (PLIsk). Ultrasound toothbrush provide the best and the most efficient outcome in patients with orthopedic implant restorations, study scanning electron microscopy showed that the samples of ultrasonic toothbrush bristles are more resistant to abrasion during the three-month use of toothbrushes.

The students are to be good not only in the theoretical knowledge but also have good manual and analytical skills to solve various problems in practice according to the modern endodontics. The dentistry department staff of the Omsk State Medical Academy has accepted an invitation to cooperation with the company FKG Dentaire S.A. in order to support the students’ knowledge and skills in working with the root canals. The result is the acquisition of endodontic skills by the graduate and postgraduate students in working with rotary NiTi files of RaCe. When teaching students to work with rotary NiTi files, emphasis was made on quantitative control of using a too used in the root canals. FKG offers an extremely simple and yet reliable method of accounting of the use of tools SMD (Safety Memo Disk).

According to the literature about 5% of the adult population experiencing extreme fear of dental treatment, 20-30% experience severe or moderate fear. A visit to the dentist for these patients is the psychoemotional stress. For the first time in outpatient dental practice, the efficiency of application of motivational interviewing (MI) to reduce fear, excitement and anxiety of patients was applied. 224 people (men and women aged 18 to 57 years) were tested on the scale of the Spielberger-Hanin (situational anxiety) and Schwarzer, Romek, Erusalema (self-efficacy). Assessed for changes in their functional parameters (blood pressure, heart rate, breathing rate) before and after the intervention. The use of motivational interviewing increases the safety of dental procedures, and cognition fears and expectations of the patient helps to avoid conflict situations.

A primary aim of root canal treatment is to completely clean and shape the root canal system. Various instruments are available for endodontic instrumentation. Although rotary systems do prepare many canals without major procedural errors, they do not address canal types with long-oval or flat cross sections. A newly developed self-adjusting file (SAF) was designed to address the shortcomings of traditional rotary files by adjusting itself to the canal cross section. Latest research with microcomputer tomography demonstrates that the affected area of a root canal operated through SAF shows that majority of the area was operated with the help of a popular nickel-titanium rotary system.

Spongy (intraosseous, intralingualary and intraseptal) are intraosseous injection and, therefore, vascular. This paper is about the nature of positive aspiration, which has not previously been studied in these kinds of local anesthesia. The frequency of positive aspirations in spongy anesthetics was 90% and corresponded to the same value of the clinical «success». A little higher frequency of these parameters was observed at the ILA, which was due to several puncture on a single tooth anesthesia. The decisive factor in the success and the nature of aspiration is an anatomical condition of the interdental septum, its cellularity

The essay demonstrates the results of comparative analysis showing the extent of cleansing of root canals using different groups of antiseptics. 50 metallographic sections of extracted teeth pre-treated with ProTapers, with 17% ethylene diamide tetraacetate solution and the investigated irrigations solution were used for research. The research was made using the electronic microscope. It was revealed that despite the use of relatively strong antiseptic preparations used in endodontics, no complete cleansing of the root canal was attained. The cleansing capacity of the irrigation fluid increases upon being treated with vibration methods, in this case – ultrasound treatment

In the last decade, much attention is given to regeneration of pulp tissue. Arsenal of drugs for the treatment of inflammation of the pulp is wide and varied, however, the frequency of receiving the patients with pulpitis in dental clinics remains high, reaching 30% of the total number of visits. The imperfection of biological treatments an initial pulpit, and the rate of caries complications dictate the need for new facilities and improving the known methods of therapy. The aim of our study was to investigate the antimicrobial activity of genotoxic and cytotoxic properties of cements «Biodentin» (Septodont, France), «Rutdent» (TehnoDent, Russia) and the adhesive «Futurabond NR» (VoCo, Germany) used for the treatment of deep dentine caries and early forms of pulpitis, for scientific justification of the choice of material, which has the highest biocompatibility with the tissues of the pulp.

The emergence of modern materials for therapeutic dentistry significantly increased the possibility of clinicians to conduct restoration of severely damaged teeth. We present a clinical case of recovery of the damaged tooth crown. After the root canal obturation by thermafills a surgical lengthening of the tooth crown was conducted. Then the tooth was restored with the help of fiberglass post fixed on the dual-curing cement and subsequently covered with all-ceramic crown. In cases of fracture of the clinical crown of the tooth crown lengthening surgery and restoration of the tooth with the use of «post-and-core» system is a good alternative to prosthetics on implants in cases of absence of the pain, tooth mobility within the normal range and the possibility of providing high-quality endodontic treatment.

The article describes the methods of repeated endodontic treatment of destructive chronic apical periodontitis after apicectomy. 20 patients aged 25 - 35 years with a diagnosis of chronic apical destructive periodontitis were treated. All patients had a history of surgical apicectomy. A clinical example proves the efficiency of the proposed technique. The drug of «Bioimplant» together with the gel of «Collapan» were used in the treatment.
