Oral diseases prevalence remains rather high among population in most Russian regions. In such situation prevention of
widespread oral diseases should be a priority of oral health services.
Complex preventive program providing the differentiated approach based on age and oral condition of patients is developed
in Moscow State University of Medicine and Dentistry. It is expected that systematic realization of the program will
allow to decrease oral diseases prevalence on population level.

In the conducted study was examined the dentine structure at the bottom of the tooth cavity after application of the remineralized
medicine BV under scanning electronic microscope control. It was analyzed a 12 teeth, extracted on clinical indications.
It was revealed that under remineralized therapy the bottom of the tooth cavity was hardened.

A comparative evaluation of tooth mobility in patients with periodontitis of varying severity in both jaws of the equipment
measuring the periodontometr. Found that the instrumental method allows more accurately determine the status of tooth
mobility structure in numerical terms (mkm/5N). Also identified patterns in the data measurement filled teeth.

In article data of the modern literature on complications of treatment of chronic illnesses of a pulp. Application of modern
laser technologies in endodontic urged to help with treatment improvement of quality. The comparative estimation of efficiency
application the diode laser is spent at endodontic treatment chronic forms pulpitis in the nearest and remote terms of supervision
with traditional methods of treatment. Data of clinical, tool and radiological researches of 146 patients who were under
supervision in a current of 24 months at which 184 teeth concerning a chronic pulpitis either removal of tooth pulp on orthopedic
or parodontics indications has been cured are processed. Results of clinical researches have shown decrease in quantity of complications
in group with application the diode laser for endodontic processing of root channels in the remote terms of supervision
in 3,8 times in comparison with group of patients at which processing was spent traditional. Clinical examples are resulted.

In given clause application of a method of liberation histamin basofile cells has been shown, that to blood to samples of
the materials used in stomatology, has revealed the highest level of liberation histamin on samples of root paste Foredent.
Samples Sealite Regular, Zinc oxide eugenole, alloys of metals Superpal and Super KM do not render damaging action on
these blood cells.

This article describes a methodology for the preparation of transparent teeth. The teeth were removed after complicated
caries. Owing to the way of visualization it is possible to receive the visual three-dimensional image of all root channels system
with preservation of all volume of tooth tissues to assess the anatomy of root canals, the fillings quality and evaluation of
possible mistakes and complications

There were studied follow-up results of orthopedic treatment of 150 patients with traditional and modern constructions of
dental prosthesis. There were discovered dynamics of changes in periodontal status of abutment teeth in various conditions
after finishing of prosthetics, including dependence on obturation character of tooth root canal and method of prosthetics.

The examination and surgical treatment of 30 patients with destructive forms of chronic periodontitis was performed. A
comparative analysis of effectiveness of surgical treatment of patients with destructive forms of chronic periodontitis with
the use of traditional methods and using intraoperative microscopy with the technology of retrograde filling by MTA Pro-
Root. The study showed high efficiency of operation radix ectomy using intraoperative microscopy, retrograde filling by MTA
ProRoot.

This paper presents a complex clinical case of endodontic retreatment of molar with associated defects - metal instrument
fracture and two perforations of the canal walls of different localization - in two visits. The process of endodontic treatment is
made possible through the use of an operating microscope in dental clinic, which allowed to specify the anatomical structure
of root canal, with the help of magnification and increased illumination in order to facilitate the implementation of the basic
stages of preparation, sealing, ultrasonic cleaning, extraction of fragmented tools, and finally, a tight sealing the perforations.

The article provides analysis of the major problems in endodontics, identified the causes of treatment failures and suggests
ways or their solutions. We consider such solutions to the problem of violations of the boundary seal, as the application of the
method of vertical condensation and filling the root canal to the physiological apex. In the focus of scientific research are also
problems of bacterial origin of periapical lesions, poor access and search of the root canal. According to specialists in endodontics,
root canal filling by vertical condensation of thermoplastic gutta-percha is currently considered the most reliable.

In the article we examine the algorithm development of extensive caries treatment of secondary teeth with unformed
roots. The importance of usage in children stomatology is noted in necessity of consecutive endodont actions.

Dental computer tomography is a modern radiologic method that allows to obtain a comprehensive
diagnosis of the state of dental and oral-facial system, which is important in all areas of dentistry and maxillofacial
surgery. Due to the high image quality, features of the software, the method allows to diagnose various diseases and conditions
of teeth and jaws, to plan treatment and evaluate the effectiveness of therapeutic measures.

Pilot researches. A role of the microbic factor at endo-perio lesions. Correlation of contents of a biofilm of a bone pocket
and the root channel.

The purpose of our researches was studying of features of distribution periostits among adult population of Baku. We
analyze the out-patient cards of the patients which have addressed in the Republican stomatologic Center in 2003-2008
by the Method of casual sample 638 out-patient cards are selected. It is necessary to recognize the revealed motivational
promptings also as the factors, creating a favorable background for development periostits. To some extent all of them are
inherent also in representatives of control group, and it gives the basis to believe, as they potentially are under risk of disease
periostits. Therefore it is necessary to strengthen seriously among the population sanitary - educational work on preventive
maintenance of stomatologic disease. Socially-epidemiological picture periostits, and such important components
of its parameters as age, sexual, seasonal and socially-professional diseases, influence sanitary - hygienic, behavioural,
motivational and roles of hygiene of an oral cavity and other risk factors on disease level, open laws of circulation periostits
among adult population. On the basis of the received laws real possibility of development of effective system of preventive
maintenance periostits for the first time is created.

Progress and somatic symptoms of many general diseases in elderly people have a number
of peculiarities. In connection with the pattern of involutional processes in the body of elderly
people, the idea of a typical course and manifestation of certain diseases vary greatly. In order to choose a conservative tactics
of endodontic treatment of chronic apical periodontitis these peculiarities should be considered.
