A comprehensive dental examination and a sociological survey of 370 employees of the SEZ “Alabuga” and 297 employees of JSC “Chemical Plant named after L.Ya. Karpova "(Mendeleevsk). Statistical data collection, processing and analysis of the results were recorded on a personal computer in the spreadsheet environment of Microsoft Office Excel 2016.

The materials presented in the article are based on the analysis and study of various methods of parametric and nonparametric statistical analysis. Moreover, the use of the discriminant analysis module of the STATISTICA system contains a large set of manipulations to perform multiple functional analysis, including the module of factor and cluster analysis. To analyze qualitative data, change frequencies, determine the significance of differences of one attribute from another, the chi-square criterion was used. Comparison of empirical (actual) and expected (theoretical) results was carried out using the agreement criterion (Pearson), the absence or presence of statistically significant differences ― using the value of the exact Fisher test, the presence or absence of a specific factor in a particular group ― using a statistical indicator of the odds ratio and confidence interval.
