Summary:

Objective: to develop a questionnaire for assessing the level of dentophobia and dynamics of the relationship in the «doctor-patient» in the course of treatment and to conduct its clinical trials. Material and Methods. 90 patients aged 26-56 years with chronic generalized periodontitis have been examined. The research has been conducted by Hospital Anxiety and depression (HADS) questionnaire to determine the level of dentophobia; psychophysiological testing was carried out on the hardware-software complex (APC) «NS-Psychotest» (LLC «Neurosoft», Russia, Ivanovo, 2007). Clinical examination included examination of the mouth and the index of assessment of hard tissue of teeth and peri-odontal tissue: a defining simplified oral hygiene index (UIG), sulcus bleeding index (IR), gingival index (PMA). The survey was carried out before the treatment and 3 months after the treatment. Statistical analysis was performed in the program Statistica. Using non-parametric methods (Wilcoxon test, criterion A2, Spearman correlation coefficient). Statistically significant differences with p < 0,05 were considered. Results. The development of the questionnaire was carried out in accordance with all generally accepted standards. The initial testing was performed easily by patients. During the clinical trials visible results of the proposed questionnaire were obtained that proved its sensitivity to the changes in dental and psychological status of the oral cavity. Conclusion. The practical application of the questionnaire determines the level of dentophobia during the first visit. The data of the questionnaire identify the differentiated deontological approach. It improves the relationship with the patient, reduces his level of dentophobia. The reduced dentophobia promotes compliance and psychologically comfortable communication in the doctor-patient system, which also contributes to the prevention of emotional burn out among dentists.

Summary:

Objective: to study the adhesion of oral microflora and the degree of penetration into the structure of the basis of structural polymers in a comparative perspective. Material and methods. The object of the study is based on samples representative of the modern basis of polymers subjected to contamination by microorganisms in the experiment. Assessment of the quality of the resulting surface samples of basic dental polymer after polishing using a scanning ion microscope. The study of adhesion of microorganisms on the surface of the samples was performed in the experiment in vitro by the method of V. N. Zarev, 2006. Fluorescence imaging was held to study microbial penetration into the interior of polymers of microorganisms using a confocal laser scanning microscope. Results of the study revealed a degree of adhesion and penetration of microorganisms to the surface and the structure of the base polymer. Conclusion. The findings suggest the importance of final basic polymers. Thermoplastic polymers are characterized by complex processing, concerning promote greater adhesion and infiltration of microorganisms into the interior of the construction in comparison with the acrylic polymers.

Summary:

The aim of the research was the study of the cell proliferation indices of the gum epithelial cells in patients with parodentium inflammatory diseases accompanied by gastroesophageal reflux disease (GERD). Material and methods. 160 patients were examined, 60 patients with parodentium inflammatory diseases accompanied by NEGERD, 40 patients with parodentium inflammatory diseases accompanied by GERD. The comparison groups consisted of 40 patients with diseases of parodentium without esophagus pathology and 20 healthy persons. Results. On the basis of the conducted clinical-endoscopic, immune-histological and morphological examinations it was established that gingivitis and periodontitis are successive stages of disturbance of the cellular homeostasis of gum epithelial cells. Conclusion. The enhancement of the processes of proliferation and apoptosis promotes the progression of the structural alterations in the tissues of parodentium and oesophagus and may serve as additional diagnostic and prognostic criteria of the diseases of parodentium accompanied by GERD.

Summary:

Objective: to study the qualitative and quantitative composition of microflora in the root canals of teeth in the treatment of patients with chronic apical periodontitis. Material and methods. The efficiency of the treatment of chronic apical periodontitis was determined in two groups of patients: the main group 1 (18 persons) and comparison group 2 (11 persons), by examining culture-biochemical properties of the contents of the teeth root canal (RC), the concentration of total protein and leukocyte. For endodontic treatment in group 1 the «Radent» was used and in group 2 was used «Krezodent.» Results. In group 1 suppression of anaerobic microorganisms was found and the reduce of occurrence of streptococci, the growth of Candida, Enterobacterium and Corynebacterium did not detected. In group 2, rising Candida, pyogenic streptococci, staphylococci and anaerobic microorganisms was found. The concentration of total protein and white blood cells in teeth RC contents in groupl decreased significantly and in group 2 contents did not change. Conclusion. The pathological process in the periodontium under chronic apical periodontitis supported predominantly coccal and anaerobic microflora, with exacerbation prevail streptococci, Neisseria and enterobacteria. Inflammation of the periodont supports leukocyte cells that synthesize the protein molecules. «Radent» has a strong antibacterial and anti-inflammatory effect.

Summary:

The purpose: to determine the most effective method and sequence of polishing systems to achieve the effect of «dry light» of the final restoration ofthevestibular surface of the incisors and molars chewing surface of the hybrid light-cured composite materials. Material and methods. Material for polishing for the restoration divided into three groups: 1. Grinding discs — firm TOR VM with three types of grit: coarse, medium, soft and super soft, firm 3M ESPE «Sof-Lex» ultrafine polishing wheels and contoured 2. Silicone heads — polished Enhens, Dentsply, polishers EVE. 3. Polishing brushes Jiffy Regular Brushes, Ultradent; nylon brush prevention. Results. The best way to give effect to the «dry light» was the next sequence of the materials: polished Enhens, Dentsply, ultrafine polishing wheels of orange and yellow 3M ESPE «Sof-Lex», polishing brush Jiffy Regular Brushes, Ultradent. The best effect of polishing brushes obtained by using it in complex with polishing paste. Polishing process with all of the materials was performed with water. Conclusion: When polishing the vestibular surface of incisors and the occlusal surface of molars it is necessary to consider the saving of macrorelief of restoration or the need to remove excess material, without affecting areas of natural tooth tissue, which should be used or exclude certain types of abrasive polishing materials.
