[Dependence of dental status from the level of endogenous intoxication in chemical industry workers based on the oral fluid composition study].

The aim of the study was to assess the dependence of dental status from the level of endogenous intoxication in chemical industry workers. Dental examination and analysis of the composition of the oral fluid were performed in 101 workers dealing with production of chlorophenoxyherbicides (CPH) and 100 individuals of the control group having no contact with harmful production factors. The survey revealed higher intensity of dental caries among workers (RR=1.

[Status of the buccal mucosa in subjects occupationally exposed to chlorophenoxyherbicides].

Examinations of workers engaged in the production of chlorophenoxyherbicides showed high prevalence of diseases of the buccal and labial mucosa with a trend to development of hyperkeratosis (exfoliative cheilitis, hyperkeratosis of the tongue, lips, buccal mucosa (BM), flat form of the BM and red lip leukoplakia). Cytogenetic effects of toxins on BM result in an increase of keratinization level, higher incidence of nuclear abnormalities, and appearance of the micronuclei in BM epithelium. A direct relationship between the severity of these symptoms, duration of exposure, and intensity of workers' contact with chlorophenoxyherbicides was revealed.
