TEETH IMPACTION: CHALLENGES AND SOLUTIONS.

The aim of the study was investigation of statistics of impaction and semi-impaction in permanent dentition in the population of Georgia, revealing the correlation and feedback of expressed adentia and retention in different groups of teeth. Study was also aimed to determine any regularity in reduction of tooth number of the skeleto-dental system. To comply with this goal, 1000 panoramic images of patients, from 12 to 35 years of age 651 women and 349 men have been examined.

EFFICIENCY OF CHELATING IRRIGATION AGENTS FOR REMOVING A LUBRICATED DENTIN LAYER OF ROOT CANAL.

The study is aimed at investigating the smear layer, formed on the walls of dental root canals as a result of endodontic treatment, by using scanning electron microscope (SEM) and determining its removal and/or modification quality after applying water solution of 18% ethylenediaminetetraacetic acid (EDTA) and gel. 50 extracted teeth preliminary prepared using Step-Back technique has been studied. Experimental teeth were randomly divided into the following 3 groups: control group (20 teeth), study group I (15 teeth) and study group II (15 teeth), respectively, irrigated by water solution of 18% ethylenediaminetetraacetic acid (EDTA).

ANATOMO-MORPHOLOGICAL FEUTURES OF THE ROOT CANAL SYSTEM IN GEORGIAN POPULATION - CONE-BEAM COMPUTED TOMOGRAPHY STUDY.

Incomplete and superficial knowledge of morphological types and anatomical variations of the root canal system will become the reason leading to the failure of endodontic treatment. cone-beam computed tomography (CBCT) - it is a technologically more sophisticated, interesting, reliable, non-invasive imaging technique with high degree of visualization, considered as a particularly important and useful tool to study complexity and variability of canal system. 2753 teeth of 228 patients have been studied by CT.

The maxillary second molar - anatomical variations (case report).

To be acquainted with dental anatomical specificity is of great importance for dental endodontic treatment algorithm. The subject of present publication is 2 clinical cases of upper second molars, detailed characterization of, which is considered very important for enrichment of anatomical knowledge about dental anatomical variations. In one case, the reason for admission to the clinic of a 38-year-old woman was complains as of esthetic character as well as functional misbalance (disturbance of chewing function due to the damage of orthopedic construction).

[Root and canal morphology of maxillary first premolar in Georgian population].

Almost each stage of endodontic treatment is connected with structural peculiarities of teeth. One of the biggest challenges facing clinicians is profound knowledge of root canal systems which is different in various races and ethnic groups. This study is devoted to the investigation of anatomo-morphological peculiarities of maxillary first premolar in Georgian population.

Gemination or fusion? - challenge for dental practitioners (case study).

Gemination and fusion are anomalies in size, shape and structure of teeth. Gemination more frequently affects the primary teeth, but it may occur in permanent dentitions, usually in the incisor region. Geminated teeth are typically disfigured in appearance due to irregularities of the enamel.

Peculiarities of the anatomo-morphological parameters of teeth and root canals in permanent dentition in Georgian population.

One of the main reasons that cause the failure of endodontic treatment is the lack of knowledge of complex anatomy of the tooth cavity. Numerous studies over the years have established a complex structure of the tooth root system, a particular configuration of which determines the uniqueness of each tooth.Numerous researches have laid the foundation for anatomical and morphological peculiarities of root system of the tooth, their classification and nomenclature indices.

Articaine - the best choice of local anesthetic in contemporary dentistry.

Local anesthesia forms the foundation of pain control techniques in clinical dentistry. Within the rich local anesthetic drugs available in dentistry for the prevention and management of pain 4% articaine solutions achieve highest level of anesthetic potency and lowest systemic toxicity in all clinical situations, prior to its superlative physicochemical characteristics and the pharmacological profile. These are - low lipid solubility, high plasma protein binding rate, fast metabolization, fast elimination half time; low blood level.

[Polymer films of antiviral preparation Rodopes for dental practice].

There was created new medical form of antiviral reparation Rodopes that surpassed previous forms - Rodopes adhesive ointment and Rodopes ointment - and also traditional preparations Zovirax and Interferon with its increased therapeutic effectiveness. Rodopes polymer films are much more comfortable way of clinical usage and can be successfully and widely used in stomatological practice.

[Changes of adrenal cortex structure in young rats under the single influence of hypobaric hypoxia].

Histo- and ultrastructure investigation of adrenal cortex in young animals after the single administration of hypobaric hypoxia has been carried out. Hypobaric hypoxia was modeled in ventilated barocamera with pO(2) decreasing till 364-372 mm Hg on the 15 albino male rats 51-120 days of age and 90-120 gr of body mass. Duration of the experiment was 4+/-1 hours.

[Functional morphology of adrenal cortex in aging rat under the influence of barocameral hypoxia].

The aim of the study was the assessment of adrenocorticocytes morphology in aging rat under the influence of hypobaric hypoxia. Adrenocorticocytes samples were collected from 11-18 months age 15 albino males under chronic hypobaric hypoxia of 60 days duration. The exposure time was 2 hours, pO2 was decreasing till 364-372 mm Hg.
