THE STUDY OF THRESHOLDS OF PAIN SENSITIVITY OF ORAL MUCOSA TO MECHANICAL STIMULI
Abstract
Tactile and pain sensitivity of the oral mucosa has been the subject of study of a number of researchers. However, the numerical values of the thresholds of the excitation of the baro - and mechanoreceptors of the mucosa of the oral cavity not sufficiently detailed in the literature, experimental data is highly scattered, often presented without specifying the method of measurement or sections of the jaws, which were received. However, the authors note the unequal sensitivity of the mucous membrane in its different areas and its dependence on the presence or absence of a number of chronic diseases. Systematic study on the diagnosis of sensitivity associated with dental prostheses of the prosthetic bed tissues to pressure, virtually no. In this report the authors made some attempt to rectify this gap. It shows the numerical values of thresholds of pain sensitivity of the mucous membrane of the oral cavity of humans and animals by mechanical action on the basis of literary data and results of numerical analysis of the mathematical model “obturator maxillary prosthesis - mucosa the edges of the defect of the upper jaw”. The average value of the lower threshold of pain sensitivity was 20,72 g/m2 according to the data of different authors, and the upper limit was 63,82 g/m2.

DENTAL AND SALIVARY STATUSES OF MEN WITH ALCOHOL USE DISORDER DEPENDING ON AGE
Abstract
Introduction. High level of alcohol consumption in Russia and significant need of dental care especially among patients with alcohol use disorder (AUD) dictate necessity of investigation of dental pathology features among this group of patients. The aim of the study is to research dental and salivary statuses of men with ADS depending on the age. Methods. Examination of indices of dental and salivary statuses was carried out among two age groups of patients with second stage of AUD aged 25-44 years - «younger» and 45-64 years - «older». Methods of statistical analysis were Pearson's chi-squared test, Mann-Whitney U test and logistic regression. Results. In studied group median of DMFT with Q1 and Q3 is 14,0 (11,0-20,0) in younger group and 23,0 (18,0-29,0) in older group with significant prevalence of missing teeth in older group (p<0,001). According to the results of F-(D+M) investigation, more than 90% of the research subjects had negative attitude towards their dental health but in older group the index was two times lower than in younger group (p<0,001). The need of prosthetic care among study participants was almost 100% (р=0,253); hygienic level of both groups was satisfactory (р=0,210). Salivary status was characterized by low salivation rate (р=0,723), acidic pH (р=0,511) and low microcrystallization potential of saliva (р=0,047) both in younger and older group. On the opposite, the indices of saliva viscosity (р=0,042) and surface tension (р=0,669) were increased. The analysis of the microcrystallization of saliva types has revealed that types г and Д prevailed. Conclusion. During the study we revealed statistically significant age differences among patients with AUD in indices of dental and salivary statuses. These findings determine the need of development of narcological circumspection among dentists and formulating the recommendations for the management of narcological patients and secondary prevention for the preservation of dental health.

ANALYSIS OF THE BASIC ANTHROPOMETRIC MEASUREMENT PARAMETERS OF DENTAL PATIENTS WITH CONNECTIVE TISSUE DYSPLASIA
Abstract
The purpose of this study was to determine the bodybuild, the basic anthropometric measurement parameters (body-weight index - BMI, Varga Index - VI, height, weight), the nature of variation thereof in relation to sex, age and possible correlation with dental health status, in adult patients with connective tissue dysplasia (CTD). A group of 360 dental patients of white race, aged 16-56, residents of St. Petersburg, including: control group of patients (n=84) not having the connective tissue dysplasia (CTD) and the basic group of patients (n=276) having the CTD, has been examined. Patients underwent complex clinical and instrumental examination of their dental, somatic status, CTD check. We have found that BMI, in comparison with VI, identifies the differences between the studied groups more accurately, and seems more preferable for diagnosis of the nutritional status and differential diagnosis of patients whether having or not having CTD. In the basic group, BMI is affected by the course of CTD and by age. In the control group, BMI is affected by age and gender. In the basic group, the course of CTD and gender affect VI. In the control group, gender and age affect VI. Correlations of the anthropometric parameters (n=320; p=0,0001) with CTD and dental parameters, have been identified. Varga Index has positive correlations with body-weight index, BMI (r=0.951), weight (r=0,837), periodontal biotype (r=0,289), and negative correlations with CTD (r = -0.290). BMI positively correlates with VI (r= 0,951), weight (r=0,856), and age (r=0.392), gingiva biotype (r=0,305), presence of dentition defects (r=0,301). BWI negatively correlates with the diagnostic bone criteria of CTD (r=-0,308; n=249) and the CTD phenotype (r=-0,323). In the examined patients, age correlates with the CFE index (index of caries-decayed, filled, extracted teeth) (r=508) positively, and correlates with the weight (r=-0.300) of the patient negatively (p=0,0001; n=320). Implementing the study of dental patients, it is necessary to take into account the values and correlations of the anthropometric measurement parameters (BMI, VI of weight, height), which correlate with age, gender and dental status characteristics (periodontal biotypes, CFE, dentition defects), as well as bone diagnostic criteria of CTD, feature of the CTD course and phenotype.

ANALYSIS OF COLOR CHARACTERISTICS FOR VARIOUS COMBINATIONS OF THE CORE MATERIALS AND ALLCERAMIC MATERIALS
Abstract
This paper is devoted to the analysis of the optical interaction of materials for the fabrication of the post-core and all-ceramic framework of a non-removable prosthesis. The gold-palladium alloy, cobalt-chromium alloy and composite materials were chosen as the material for restoration of the core of teeth. The first group of ceramic samples consisted of zirconia zirconia disks (Dental Direkt, Germany), 0.3 mm thick and 0.5 mm thick with different transparency (high, medium and low). The second group of framed ceramic materials ware disks from lithium disilicate E.max Press (Ivoclar Vivadent, Liechtenstein), 0.4 mm thick and 0.6 mm thick from blanks of different transparency (high transparency, low transparency, medium opacity, high opacity). The study was based on the principle of comparative analysis of the obtained samples on a spectrometric color analyzer and comparing the reflection coefficient. The dependence of the brightness of the finished restoration on the type of the core materials and all-ceramic discs of different thicknesses has been determined, which should be taken into account when calculating the final ceramic restoration color. It has been established that a composite base should be used for prosthetics of an aesthetically significant group of teeth. In turn, core materials from CoCch and Au alloys according to colorimetric characteristics are not suitable for this prosthesis and they must be primed with opaque materials beforehand.
