THE PREVALENCE OF NON-CARIOUS TOOTH DEFECTS ASSOCIATED WITH INDUSTRIAL EXPOSURE IN RESIDENTS OF PENZA REGION (RUSSIA)

Abstract

— Aim of the study: to assess the level of dental pathology in Penza Region (Russia) and estimate the impact of the industrial environment. Materials and methods: A clinical examination and analysis of the frequency of enamel erosion, fluorosis and hypoplasia, wedge-shaped defect and multiple enamel cracks were carried out among the main professional groups of the region's population — workers of the machine-building and timber processing industries in the Penza region. Results and Discussion. Among the residents of Penza region, the frequency of enamel erosion was 4.0%, pathological tooth wear — 7.1%, wedge-shaped defect — 6.1%, multiple enamel fractures — 11.1%. There is a high frequency of noncarious tooth defects that occur before teething. In patients working in the machine-building industry, a high frequency of pathological tooth wear was noted (24,5%); in workers of the timber processing industry, it was 2 times lower (12,6%), as well as a high frequency of wedge- shaped defects, enamel erosion and multiple enamel cracks — all this was 2–2.5 times higher compared to similar indicators in patients from agricultural populations. However, the prevalence of dental fluorosis and hypoplasia was almost the same as in the agricultural population. Conclusion: Penza region has a high prevalence of dental fluorosis and hypoplasia. At the same time, the influence of industrial environment on the incidence of various types of non-carious dental pathology in workers of machine-building and timber processing industries in Penza region was established.
