Occupational exposure to acid mists and periodontal attachment loss

Abstract

This study investigated the hypotheses that occupational exposure to acid mists is positively associated with periodontal disease, assessed by periodontal attachment loss. The study sample included 530 male workers at a metal processing factory. Data were obtained from interviews and oral examinations. Periodontal attachment loss was defined as > 4mm at probing, in at least one tooth. A job exposure matrix was utilized for exposure evaluation. Exposure to acid mists was positively associated with periodontal attachment loss > 4mm at any time (prevalence ratio, PRadjusted = 2.17), past (PRadjusted = 2.11), and over 6 years of exposure (PRadjusted = 1.77), independently of age, alcohol consumption, and smoking, and these results were limited to workers who did not use dental floss. Exposure to acid mists is a potential risk factor for periodontal attachment loss, and further studies are needed, using longitudinal designs and more accurate exposure measures.

Prevalence and risk factors of non-carious cervical lesions related to occupational exposure to acid mists

“…21 Exposure to acid mists has already been reported to be a risk factor for oral mucosa lesions among workers without lip sealing because this increases the intensity of acid mist exposure in the mouth. 23 We believe that using the protection of personal equipment (namely masks) could prevent the action of acids in the oral cavity of workers, independently of lip sealing. Almeida et al 23 have reported periodontal attachment loss (> 4 mm) in workers exposed to acid mists, independently of age, alcohol consumption, and smoking habit, but these findings were limited to workers who did not use dental floss.…”
