We studied 229 previously obtained CBCT images. It is revealed that a incidence complicated root canal morphology of mandibular teeth (two root and two root canals in mandibular incisors, canines, premolars; C-shaped second molars and premolars) were two root canals in mandibular incisors - 47,2%, first premolars - 20,5%, two root and two root canals in canines - 6,1%, second premolars - 3,5%,C-shaped second molars - 2,9%. The incidence of C-shaped canals in mandibular first premolars were 14,4%, in mandibular second premolars - 0,9%, in second premolars - 2,9%.

Cerebrovascular accidents due to the high prevalence and serious consequences for the health of the population represents an important medical and social problem. The purpose of the work was to determine the clinical significance of diseases of dental system and how best dental care in the acute phase of stroke. Our study revealed that dental intervention in acute stroke are safe subject to the positive dynamics in the condition of patients and carrying out preventive measures.

In order to justify the selection of the optimal methods of sterilization of endodontic instruments studied the activity of new cutting and underwent repeated sterilization of endodontic instruments based on laboratory studies. In assessing the impact of different methods presterilizing cleaning and sterilization on the properties of endodontic instruments found that the ultrasonic treatment and a heat treatment to a greater extent change the properties of instruments. It was shown, in step presterilizing endodontic cleaning instruments manual washing practically no negative influence on the cutting of its activity, while an ultrasonic treatment greatly reduces it.

The article is devoted to the development and clinical testing of new paste for temporary fillings root canal for the treatment of destructive forms of chronic periodontitis. In a clinical study involved 30 patients. It was established that the most favorable effect in the treatment of destructive forms of chronic periodontitis observed when applying a paste comprising a mixture of: a powder of calcium hydroxide (40 g), ciprofloxacin (10 g), minocycline (10 g) metronidozol (10 g) mixed sterile water.

On the basis of analysis of primary medical records 9158 (3329 males and 5829 females) patients of outpatient clinics average elderly studied the prevalence of pain and paresthesys of the oral mucosa and tongue in people of different age groups. Profile is defined outpatient medical institutions, in that appeal and pass the examination and treatment of people suffering from painful phenomena and paresthesys of the oral mucosa. The cause of the factors playing a role in the origin and development of the said disease in older age groups in their treatment in dental and somatic outpatient clinics . The analysis of the role and place of various experts in the complex treatment of these patients, as well as define the sequence of connecting them to survey patients with stomalgys.

Treatment of complicated forms of caries in permanent teeth with unformed roots tops in children is the most relevant today. Among the patients who applied for pediatric dentist’s help the percentage of asymptomatic pulpitis is about 1/3. Irrational treatment of the teeth trauma is often leading to the development of acute or chronic pulpitis, sometimes it can lead to death of the pulp and injure the roots «growth plate». After applying only calcium pastes the pulp can be infected and that also lead to the death of the tooth.

One of the fundamental problems of modern dentistry is to keep the temporary teeth, namely the viability of the neurovascular bundle to the terms of the physiological change of teeth. For each of the second case of complicated forms of caries characterized by the presence of cavities on the approximal surface of the tooth. The aim of this work was to improve the condition of tissue diagnostic methods of temporary teeth with varying degrees of formation of roots. We have examined 665 children of Omsk from 3 to 8 years, of which identified a group comprising 22 people, with 29 temporary molars with cavities on the approximal surfaces with varying degrees of root formation and preliminary diagnosis of «chronic pulpitis». In the process of follow-up, according to X-ray, the degree of resorption of the roots of deciduous teeth treated for «chronic pulpitis» piloted by biological methods did not differ on the timing and nature of the flow parameters of the symmetrically disposed arranged teeth intact.

The complex technique of treatment of caries of a dentine with application of a preparation from brown seaweed and the low-intensive laser is presented in article. 40 patients at the age of 21-30 years with the diagnosis dentine caries, the II class on Black were investigated. In the real work clinical, electric pulp testing, radiological, densitometrical methods of research are presented. The comparative analysis of these data before treatment is carried out 6 and 12 months later. Improvement densitometrical and the electric pulp testing of indicators after the carried-out treatment of caries of a dentine is defined. As a result of the conducted researches efficiency of the combined application of a preparation from brown seaweed and low-frequency laser radiation is shown, at dentine caries.

The example of the clinical diagnosis and treatment of cases of intussusception lateral incisor of the upper jaw is carried out a detailed analysis of the stages of endodontic treatment and work with a microscope. Dental imaging allows to accurately diagnose the type of intussusception, a microscope in a dentist gives you a more detailed and highly professional the ability to treat, especially in difficult clinical situations.

Nowadays more and more attention is paid not only to efficiency but also to safety of the treatment. When anti-inflammatory drugs are assigned to a patient, it is necessary to take into account etiology and pathogenesis of the disease, presence of concomitant pathology, as well as peculiarities of pharmacokinetics and pharmacodynamics of these medicines. With this approach dentist will be able to perform personalized choice of pharmacotherapy.

The retrospective analysis of 468 medical records of the patients seeking for dental care was carried out. Information on the dental status of the patients received during the primary examination was studied. It was noted that from 15 points on check-up list the third part of indicators aren’t informative, the third part filled formally that calls in the question pithiness of information. Periodontal condition, availability and use of removable dentures, data on smoking and diet does not evaluate at the primary examination. The use of the existing Check-up list of primary examinations does not allow to get enough information for an objective assessment of oral health of the patient, therefore, it should be modernized.

This article deals with the conservative treatment of chronic periodontitis in the acute stage without the «open period of the tooth» and mandatory appointment of antibiotics and anti-inflammatory drugs. 17 clinical cases are presented with a detailed description of the methods of treatment and the results. 16 patients aged 28-65 years with a diagnosis К04.7 were treated. Positive results confirmed clinically and radio graphically after 6-12 months. The treatment takes place without complications and complete recovery of bone structures in the former foci of destruction is faster in teeth with one root canal, do not expose previously endodontic treatment.

The authors tested a palatal cystotomy option in the treatment of extensive cystic formation of the maxilla in a patient with hemophilia. The use of this technique in a patient with a factor VIII deficiency were reasonable and based on existing experience of surgical treatment of cystic formations of the upper jaw, which is discussed in this article.

From the moment of opening of antibiotics, improvement of stomatology materials and tools, and also the endodontics of technologies allowed to increase significantly an indicator of success of endodontics therapy for the last hundred years. Results of treatment of special cases which were considered hopeless earlier, such as treatment the periapex of complications, reached high levels of clinical success now. Thanks to efforts of scientists and clinical physicians viability of tooth without pulp can be maintained the long period.
