The problem of a technique of surgical processing of system of root channels remains actual in therapeutic dentistry. Emergence single nickel - titanium rotating tools in dentistry allows to reduce probability of their separation in the root channel. In work results of a pilot study of cyclic fatigue the endodontic machine nickel-titanium tools and their microscopic analysis are considered.

In recent decades, the most important problem in clinical medicine and, in particular, the practice of dentistry, is to find ways and methods to improve the resistance of the organism, the maintenance of homeostasis at the physiological level. One of these methods is acupuncture, currently receiving increasing recognition. Mechanisms to ensure that the therapeutic effect of acupuncture to date remains understudied. In this paper, we studied 120 patients with chronic apical periodontitis. Patients were studying the functional state of the autonomic nervous system via metered electrophoresis adrenaline and carbachol in the skin of the forearm as described in the modification A.V. Loginova, A.F. Zharkin and test dermographism. For acupuncture diagnosis method was used in the modification E. Nakatani (Riodoraku) A.I. Nechushkina. The findings suggest the possibility of immune and prevention of immunosuppressive state with the help of acupuncture in the treatment of patients with chronic apical periodontitis. This method is technically simple, harmless, economically efficient, no complications, in contrast to drug therapy and physical therapy. All this makes it advisable to include acupuncture in the range of therapeutic interventions in chronic periodontitis.

The article is devoted to the development and clinical experimental testing of new pastes for filling root canals of teeth with chronic periodontitis. The experiment put on 80 outbred rats in the clinical part of the study involved 93 patients (42 men and 51 women), all treated teeth 114. It is established that the most beneficial effect in the treatment of destructive forms of chronic periodontitis observed when using 2 simultaneously active substances (choline salicylate and chondroitin sulfate) in the paste introduced into the periapical lesion.

We studied the histological condition of the pulp of the tooth on 1, 3, 7, 14, 28 day after exposure microsecond Nd:YAG laser with 4 W after removing stamped crowns and composite fillings. The absence of the pathological effect on the tooth pulp microsecond radiation Nd:YAG laser with a water jet cooling after removal restorations from composite material, as well as water spray cooling during removal of dental prosthetics.

The dentist on therapeutic reception is always a matter of choice, of choosing a particular method or material in a particular clinical situation. This relates to the question of the application of endodontic systems: for or against? Unfortunately, it is uncertain at what minimum amount you need to use pins. It is also necessary to remember about the anatomical features of the teeth and roots that need to be considered when selecting endodontic systems. And, of course, fixing the posts on syler, we must achieve coronal and root of Hermeticism. In this paper, we conducted a comparative analysis of microbacteria of sileru used for fixing different in its structure posts: fiberglass and anchor pin. The teeth were divided into 2 groups. In the first group studied the permeability of glass ionomer material Fuji 9, on which were fixed anchor pins in the second group used the fiberglass pins for the cementation which used self-adhesive composite cement Relyx U200. When comparing adhesive fixation strength of different materials noted that the cement Relyx U200 provides the highest rate.

Combination of periodontitis and caries complications of dentoalveolar segment which is called endodonto-periodontal lesion is one of the most complicated pathology because of the difficulties of correct diagnosis and treatment. Using only intraoral X-ray, orthopantomography can lead to doctor’s mistakes, and afterwards - complications after the treatment. Using computed tomography allows to find out anatomical features of root canals, to determine the location of root furcations, additional canals, to evaluate condition of periodontium. Thorough clinical diagnosis and using computed tomography allows doctor to assess the prospects for the treatment planning and dynamic monitoring, and the most valuable thing - to improve the quality of treatment.

Pregnant patients at the dental reception represent a special risk group due to some specific physiological rearrangements that occur in a woman’s body. This is the time of an active growth of dental diseases and exacerbation of previously existing chronic infections, both somatic and cavitary. Taking into account the duration of gestation, critical periods and comorbidity, determined was an algorithm of providing safe dental care including development of methods for correction of mental and emotional state of a pregnant woman as well as a safe local anaesthesia.

The study investigated the dynamics of temperature changes on the outer surface of the tooth root during root canal obturation using continuous wave technique. Established the safety of this procedure for periodontal tissues, which allows us to recommend it for use on an everyday dental practice.

The authors presented the highest standards of mandibular teeth anesthesia used in dentistry. Different variants of anesthesia, depending on the group membership of the tooth, the expected duration of the intervention and nosology are presented. The algorithm of anesthesia for mandibular block failure is proposed. Described the indications for the use of periodontal ligament and intraseptal anesthesia methods. Recommendations to the choice of the injection needle and dosage of the anesthetic are given.

In the microbiological study in was proven that clinical use of the ozone with the HealOzone device effectively decreases the number of germs (Р < 0,05). Besides that the changes in the microbiota spectrum showed the elimination of pathogenic species. Long term results on the base of X-ray assessment in the main group, where clinical use of the ozone took place, showed the complete resolution of the pathological changes in the periapical region in 63,3-63,6% of the cases. Meanwhile in the control group, where ozone was not used, the regeneration of the bone in the periapical zone was found in low number of the cases. Data was statistically proven (Р < 0,05). The results of microbiological and clinical study shows that clinical use of the ozone with the HealOzone device in the protocol of chronical apical periodontitis treatment effectively decreases the number of germs and their spectrum and increases the effectiveness of the treatment.
