In article the basic parameters of loading of the doctors and apply of the patients on a therapeutical stomatological reception
in the specialized establishment of federal submission (on an example of stomatological polyclinic of Management of
businesses of the President of Russian Federation), in comparison with similar parameters usual regional of stomatological
polyclinic are detailed investigated. The features of applies and loading of the doctors are established, the distinctions in
rendering of the stomatological help are allocated.

Effectiveness of anesthesia in outpatient dentistry depends on the patient's personal anxiety. Sedation affects on the
patient's gum sensitivity. But the effect of sedation depends on the level of personal anxiety. Sedation of patients with high
levels of personal anxiety reduces sensitivity, but patient`s sensitivity with low levels of personal anxiety increases.

There are several classifications of odontogenic sinusitis, which are based on objective and subjective symptoms detected
by a doctor after suffering from treatment for medical attention. The importance of clinical-topographical correlation «bottom
of the maxillary sinus - posterior teeth apices» indicates all the investigators, but the qualitative features of this aspect
in the available literature we found. The paper presents a version of the clinical-topographic description of the relations apex
of teeth and the bottom of the maxillary sinus.

Studying polymerization shrinkage composite materials on silorane basis Filtek Silorane, methacrylate composites - high
filling QuiXFill (Dentsply) and packed Filtek P-60 (3M ESPE) by a hydrostatic method (Archimedes method) on 36 samples
of materials is spent. Lower size polymerization shrinkage for Filtek Silorane (<1 %) in comparison with traditional methacrylate
composites is established.

Laser doppler flowmetry of a teeth intact, with dentine caries, an initial pulpitis and an acute focal pulpitis has been spent
at 102 patients and has been established, that in comparison with a condition of a capillary blood flow in a teeth with dentine
caries its level at an initial pulpitis increases in 2 times. At an acute focal pulpitis occurs sharp and essential (more than in
3 times) reduction of a capillary blood flow in comparison with its size at an initial pulpitis that can serve as differentsialnodiagnostic
criterion of diseases of a pulp of a tooth.

Based on the study of the morphological structure of dentin root canal established the usefulness of MtwoR in conjunction
with solvent and ultrasonic action.

Morphological changes in periodontium in response to the administration into the root canal of experimental animals of
turpentine and oil of eucalyptus were studied. Alteration of all periodontium structures under the influence of turpentine was
discovered.

Possibilities of the modern ultrasonic equipment promote deeper diffusion hydroxyapatite containing preparations in dentine
tubules and lateral deltas of root channels of teeth, by results of scanning electronic microscopy. Measurement of density profile
provides an objective estimation of features of regeneration of a bone fabric at stages of dynamic radiological control.
In work the nearest and remote results of treatment of 93 patients with chronic apical periodontitis with which treatment by
an advanced method of application of a preparation «Kollapan-gel K» in a combination to ultrasound and further by the analysis
of density profile of roentgenograms the program «SIDEXIS XG» has been spent are considered.

The 1055 patients are surveyed. Retention of certain teeth is revealed at 68 patients. It is revealed resorbtion roots of
lateral incisor of the upper jaw in 12,5% of cases. Diagnostics, preventive and treatment retention permanent teeth are actual
in respect of mediko-social rehabilitation. Early revealing of risk factors retention warns formation of difficult dental-andjaw-
facialis anomalies.

In an in vitro experiment the bactericidal activity of ozone has been studied in an ozone-aerial mixture in a different ozone
concentration concerning the pathogenic micro flora of root canal. An optimal concentration of ozone has been defined in an
ozone aerial mixture and in an ozonated physiological solution. An algorithm of usage of medical ozone has been elaborated in an
endodontic treatment of patients with pulpitis and periodontitis.

This paper presents a complex clinical case of repeated endodontic treatment of tooth 1.1, previously irrationally restored
with brass post and defective sealing of the root canal. Treatment became possible through the use of an operating
microscope in dental clinic, which allows to specify the anatomical structure of root canal in conditions of magnification and
adequate illumination what facilitates the execution of all basic stages of preparation, including cleaning the root canal from
the brass pin and a gutta-percha fragmented components. Before sealing the canal was additionally processed with ozone.

In the present research the comparison of microbiological estimation of efficiency of antiseptic medicines from Russia
and foreign has been lead, which most often applied for sanitations of root channels with diagnosis chronic periodontitis not
completed development of childrens root on their reception.

At the heart of contemporary approaches to endodontic treatment of teeth, of course,
lies the teeth-saving technologies. The paper described the basic aspects of modern endodontics
with references to world literature, introduces the concept of endodontic treatment
of teeth in one visit, which the authors believe must now become the standard quality
of endodontic treatment. The basis of the work is proposed by the author the protocol of
apical periodontitis treatment in one visit.

The breakage of endodontic instruments during root canal treatment is a challenging problem which became even more
critical after the introduction of NiTi instruments into clinical practice. The primary reasons of instrument breakage are
torsion overloading and cyclic fatigue. In this article the results of experimental investigation under cyclic overloading are
represented. Cyclic fatigue testing was performed using the glass models of the root canals corresponding to the curvature
angle of 45° and the radius of curvature about 5 mm. The artificial canal models have been made of transparent glass tubes
which allowed measuring the above mentioned parameters. The experiments have been accomplished on FlexMaster 25/.04
instruments for two configurations: 17 mm of working length and 2 mm pitch into curved part of canal, and 19 mm length and
5 mm pitch. 50 instruments were used for each case. Rotation time in the tube until the breakage at 300 rpm and the length of
separated fragments were measured. These results allowed plotting the frequency distribution function of the time and then
the probability value as the function of working time at the cyclic loading. It was shown for example that with a probability of
10% the working time is 53 sec for the 1-st experimental configuration (17 mm/ pitch 2 mm) and 67 sec for the 2-nd configuration
(19 mm/ pitch 5 mm).

High clinical efficacy of the conservative method of treatment has been revealed in evaluation of chronic apical periodontits
follow-up with the use of the «accelerated» method. Individual densitometric index (IDI) estimation promotes the objective
appraisal of the bony tissue recovery dynamics in the destruction focus. The «accelerated» method of treatment makes
it possible to restore the anatomic and functional tooth value in the shortest time.

The article is devoted to the application of well-known calcium-containing material of Vitapex produced by Neo Dental
Chemical Company (Japan). The publication presents the results of the study of microbiological, physical and chemical properties
of the material. Noted the lack of antibacterial effect, the high apical permeability of the material.
