[Risk factors and incidence of dental diseases in children in a large industrial town].

A relationship has been studied between somatic diseases, functional changes, and dental mortality in children living in urban areas having different levels of ambient air pollution. Visceral diseases have been ascertained to contribute to the development or deteriorate the course of various pathological tooth and jaw processes. Systemic diseases change the conditions of formation and maturation of dentins, which makes them less resistant. The relationship between the changes in the somatic and dental statuses of children is more pronounced when the ecological situation is poor.
