Title Occupational exposures to acid mists and gases and ulcerative lesions of the oral mucosa
Bibliographic information Mar. 2004, Vol.45, No.3, p.238-245. 23 ref.
Abstract To examine the hypothesis that acid mist or mixtures of acid mists and acid gases are associated with ulcerative lesions of the oral mucosa, all 665 active male workers of a metal processing factory in Brazil were studied. Semi-quantitative measures of exposure were estimated from a job exposure matrix, and ulcerative lesions of the oral mucosa were identified with standardized clinical dental examinations. It was found that past exposure to acid mists were positively associated with ulcerative lesions of the oral mucosa but only among workers without lip sealing, that is not having the ability to keep lips closed at rest (age- and alcohol consumption-adjusted prevalence ratio PR=3.40). The evidence of a chronic rather than acute irritative process suggests a possible step involving the aetiology of oral malignancies, which however needs further investigation.
