The main causes and clinical manifestations of xerostomia
Arakelyan M.G., Tambovtseva N.V., Arzukanyan A.V.
Abstract

There are a number of reasons that lead to inadequate salivation or complete cessation of salivation. Among others, one of the main can be systemic diseases like Sjogren s syndrome, and the use of medication, disbiotic changes in oral cavity and stress. Most often, patients with xerostomia, disturbed itching and burning in the mouth, taste disturbance, difficulty in speaking and swallowing food (especially dry), difficulty wearing dentures. Hypofunction of salivary glands can lead to different outcomes in the mouth. The most common are, first of all, the loss of gloss of the oral mucosa, it atrophic changes, the appearance of fissures and lobes on the back of the tongue, the development of angular cheilitis, disbiotic change, and the development of multiple caries. The main objective of our study was to determine the incidence of xerostomia and identify the main reasons for its occurrence. Cohort clinical examination of patients was carried out, which are on the inpatient and outpatient treatment at the clinic named after GH Vasilenko. All patients underwent a thorough medical history, a survey by tests Fox, S. Kouhena and G. Villiansona, sialometriyu method MM Pozharitskaya. Also evaluated the hygienic condition of the mouth of each test and measured the pH of saliva. Survey was conducted of 200 patients in the age group from 45 to 70 years. Based on the survey data, sialometrii, hygienic assessment of oral health, from a total of 80 patients diagnosed with «dry mouth». If xerostomia oral mucosa requires compliance with the rules of oral hygiene and constant daily moisturizing. The best method of relief of patients is to stimulate the secretion and the mandatory use of wetting agents to the oral mucosa.

Method of dynamic elimination of posttraumatic enophtalmos
Bakushev A.P., Sivolapov K.A.
Abstract

The purpose of this research paper is optimization of surgical methods of treatment of patients with fractures, defects and deformities of orbital wall with a possibility of dynamic reversal of enophthalmos in postoperative period. In the Department of Oral and Maxillofacial Surgery in Novokuznetsk State Institute of Postgraduate Medicine was developed a method of abolition ofposttraumatic enophthalmos. The method is a discission 5 mm above mucogingivalfold in area from second to six molar region in the upperjaw and windowing to anteroexternal maxillary sinus wall. Into sinus cavity is inserted a G - type titanium mini plate with silicone slab and metallic support. G - type titanium mini plate has short and long parts which are deflected 90-110°. In the long part of miniplate there is a hole for a screw, in the short one there are holes for suture to fasten a silicone slab. A support is placed to lower third of burr hole and fixed with screws to anteroexternal maxillary sinus wall. The silicone slab is joined to the short part of G - type titanium mini plate and this part is got to the orbital floor defect. The long part is placed above the support andfixed to the upper ridge with a screw. Screwing in a long part is pressed on the bone and thus a short part is put in motion and shift an eyebulb up and forward. Early postoperative complications are not observed. Late postoperative complication in 1 month after surgery was changing the position of the eyeball downward 2 mm. Produced the correction position of the eyeball. In that way this method of treatment of orbital wall fractures and defects allows to reach a constant and strong fixation of bone fragments, management of an eyebulb position displacement due to made lever system not only in surgical treatment but in postoperative period.

Features of psychoemotional state and vegetative status of patients with tmj disorders
Karelina A.N., Geletin P.N., Mishutin E.A.
Abstract

In recent years many authors have noted the dominant influence of psychosocial factors in temporomandibular joint dysfunction development. The aim of the study is to assess the severity of pain, to reveal and study the features of emotional state and vegetative status of patients with TMJ disorders. 70 patients with TMJ dysfunction and 20 people without signs of pathology of the temporomandibular joint were involved in the study. The examination included assessment ofpain, emotional state and autonomic status. We used Visual-analog scale and pain questionnaire, Beck depression scale, Leongard-Shmishek test and mathematic analysis of heart rhythm. In the study we revealed characteristic features of the emotional state in patients with temporomandibular joint dysfunction such as expressed of accentuations on the scale of cyclotides and destinati (Leongard- Shmishek test), mild degree depression due to Back scale, and disturbances of vegetative balance in the form of moderate activation of sympathetic vegetative nervous system. The presence of characteristic features of the emotional state in patients with temporomandibularjoint dysfunction confirms the role ofstressfactors in the development and worsening of TMJ disorders and dictates the need to include in the algorithm of complex diagnostics consultation of neuropsychiatrist, and also allows the dentist to correctly carry out dental treatment in the scheme of complex therapy.
