[Impact of environmental air pollution on dental morbidity in children].
Ambient air pollution was studied for its impact on the prevalence and severity of major dental diseases and on the biological age of pre-school children in ecologically tense and relatively pure regions. The lowest prevalence and severity of caries were registered in a nursery located in a control region. The mean number of permanent teeth was also more in children of the control group. Estimation of the biological age by the dental formula revealed that there were a significantly larger number of accelerated children among those living in the control region.

The paper presents the data of clinical and hygienic studies of railway cashiers' health. The main deleterious factors of their working conditions are poor microclimatic conditions, bacterial inoculation of the working area air, a forced working posture, and a high vocal load under mental stress. There is a significant prevalence of nervous, obstetric, gynecological, thyroid, and vocal diseases and oral dysbacteriosis among the workers of this professional group. There is evidence for the necessity of including the job of a railway cashier into the List of decreed contingents for periodical medical examinations.

[Development of pre-neurotic disorders in senior school students: hygienic aspects].
The prevalence of preneurotic abnormalies was studied in senior schoolboys from 4 Bryansk regional areas with different levels of radiation contamination. The study is aimed at elucidating the correlation between the rate of development of preneurotic abnormalities and the level of radiation load in the environment. ⋯ There has been no significant relationship of studied psychological parameters to the radiation contamination of an area where the pupils live; however, there is a tendency for deviation from the optimum level of anxiety in senior schoolchildren who reside in radioactively polluted area. While implementing a package of preventive measures, it is necessary to pay a particular attention to the psychological atmosphere in the family of pupils and to the pattern of their learning load.
