Results of research have shown that for 14th days of a reparation of a bone tissue of an alveolar shoot of the top jaw of rats
under the influence of a material Osteoindutsin more active synthesis of factors of growth in comparison with a material Osteomatriks
is observed.

In our work it has been established that on local anaesthetising preparations prevails IgE the sharp answer prevailing, basically,
in samples of whey of blood of women. The greatest quantity of positive tests is revealed in samples of whey of blood on
bypivacaini (4,27%), procaini (4,08%), lidocaini (3,97%). The least occurrence of allergic reactions is revealed on tetracaini
(1,29%) and epinephrini (1,59%).

Psychological testing and diagnostic of 108 persons with different types of discolored teeth were conducted as well as
with tooth discoloration after endodontic therapy. Patients motivation singularities analysis for patients which have chosen
different type of hard tooth tissues whitening the following conclusions can be done. For in-office bleaching patients motivation
of achievement predominates over motivation of approval and vice-versa for at-home bleaching patients motivation of
approval predominates over motivation of achievement.

Radiological methods are an important component in algorithm of patient examination in
endodontic treatment. Hi-tech methods, such as cone beam dental tomography, allow more precisely to plan the given kind of
treatment, and to supervise efficiency of spent medical actions in comparison with traditional radiological techniques. Introduction
of cone beam dental computer tomography in dentistry practice gives the chance to lower quantity of complications
and to raise quality of treatment.

Assessment of tooth mobility, subjected to endodontic treatment, when using removable
dentures. Changes in tooth mobility caused by several factors: 1) the impact of elements of removable dentures in the tooth
mobility structure, 2) the choice of material used for print, 3) the quality of endodontic treatment on the condition of the
tooth mobility structure.

Local anesthesiology in dentistry exist more than 120 years. Nowadays we use it in any time when treatment interfaced
with pain. On a boundary of centuries in dental anesthesiology appears a new way connected with development and introduction
into daily practice, including endodontic treatment. The usage of automated syringes start this way.

Radicular cyst treatment mostly requires surgical approach. But there are cases where this method is not effective for example
when the radicular cyst is present at the apex of the anatomically difficult configuration of the «dens in dente» tooth.
Ingrowths of the tooth structures (Dens Invaginatus) or the anatomical type of the «tooth inside the tooth» («dens in
dente») is the tooth organ development disorder and rarely met on the daily basis.
Teeth with such anatomical structure have parts of dentin and enamel that grow into the pulp chamber and sometimes into
the apical part of the tooth. The main problem in treating this pathology is the lack of the information about. Atypical anatomical
variety of root canal configuration creates difficulties for a quality endodontic treatment.
Quality of the surgical treatment mostly depends on the quality of the endodontic treatment. In order to solve the problem
in treating this pathology, new approach of treatment and diagnostics were developed. The diagnostics was carried out using
digital radiography and cone beam computer tomography.
Treatment consisted of two parts: conventional (using dental operating microscope) and surgical with apical tip resection
and retrograde preparation and obturation.

In article use of modern nanoimpregnation technologies systems of root channels of a teeth and dentine tubules of a root
with the help hydroxide cupper-calcium and L-cystein-silver solution is described. Nanoclusters preparations are entered in
root system with the help of the special devices placed in a tooth and being a source of an electric current. In a combination
to traditional methods endodontic treatments the way allows to increase its efficiency up to 98 % due to careful sterilization
and obturation all root system.

One of the sourse of the bad quality endodontic treatment leading to the development of the chronical periapical lesions
may be missed and unfilled root channel. Premolars are teeth with multiple root canal system. Authors show that inflammatory
complications in premolars happen even often than in molars. In this review teeth (premolars) investigation method
helping in acessesory root canal detection is offered and cases of the endodontic treatment of the premolars with multiple
root canals are described.

The authors present of data on the problems of use of a dental microscope in endodontic practice. Submitted questionnaire of
a referral of patients to endodontic treatment.

On a material of the sterile teeth, sealed up calcium paste, defines duration of active action of paste in the pathological root
centre at chronic forms of a periodontitis.

As part of the final state certification of graduates with a degree in Dentistry, which was implemented in 3 stages: the final
computer testing, assessment of practical skills and an interview focused on monitoring the development of competencies of
endodontic treatment. Graduates demonstrate the stages of endodontic treatment in dental simulators: Disclosure cavity with
subsequent biomechanical cleaning and shaping and obturation of the root canal, using modern techniques and materials.

In modern dentistry it was convincingly shown that the laser radiation has the potential to destroy microorganisms. This
article presents a literature review on the use of various laser systems for treatment and disinfection of root canals.
