Aim: to analyze the erbium laser effects in oral surgery in patients with the risk of bleeding. There were selected 2 groups of patients for oral surgery treatment. Materials and methods. The first group included 31 patients with bleeding risk. In this group erbium laser radiation was used for the cut and tooth socket conditioning after tooth extraction. The second (control) group of 43 patients without concomitant pathology was determined for conventional surgical treatment. Results. In the first group there was no postoperative bleeding, post-surgical pain and infection were prevented with no need for analgesics, and the wounds epithelization took 1-3 days. It takes less time than in control group. Conclusion. Application of erbium laser is a modern method which can be successfully used in surgical treatment of patients with the risk of bleeding.

Purpose: to study the properties of nanostructured coatings in orthodontic implants. Material and methods. Low and average molecular mass chitosan, 3-amynopropil-3-methoxysylan and suspensions of 5 nm and 10 nm gold nano-spheres stabilized with natrium citrate were used for nanocomposed surfaces. 2mg/ml polyethylenamin water solution was used for making the underlayer before putting polyion coverage using «POLYION-1M». The polyion covering dynamics was studied by polyquartz weighing method. Morphology of created layers was studied with atomic microscopy, elements were studied by secondary ion mass-spectrometry. Results. The best transmission among structures of chito-san/metals was showed by low molecular mass of chitosan and 8-1 Onm nanoparticles of metals. Analysis of roughness of surface shows that nanoparticles of gold make the most solid surface on 3-amynopropil-3-methoxysylan underlayer. Conclusion. The development of biocomparative materials in maxillofacial surgery is considered to be effective method of decreasing the risk of post-operative inflammatory complications by local antibacterial effect.

The purpose of the work is to prescribe combined treatment in order to determine the efficiency of cycloferon liniment. Materials and methods. 80 patients suffering from such inflammatory disease of parodentium as herpetic stomatitis and periodontitis have been examined and treated. Results. Cycloferon liniment used in the combined treatment of stomatitis and periodontitis reduces the infection load in gingival pockets, decreases local inflammation, normalizes immunity parameters, decreases endotoxemia and reduces relapse rates. Conclusion. Cycloferon liniment is an efficient medication restoring the parameters of local nonspecific immune response.

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.
