Examining Relationship between Occupational Acid Exposure and Oral Health in Workplace
Abstract Objectives: Acid mist can suspend in the air and enter the body via skin contact, the respiratory tract, or even oral intake, which pose various health hazards. Previous studies have shown that occupational exposure to acid mist or acidic solutions is a major risk factor for oral diseases. However, the findings are inconsistent and do not consider individual factors and lifestyles that may cause the same oral diseases. Therefore, we conducted a comprehensive oral health survey and collected detail information to confirm the effect of acidic solution exposure on worker’s oral health. Methods: The study selected enterprises in the metal surface treatment or electroplating industries in Taiwan that employed 300 or more employees and were willing to participate in this survey. Each enrolled subject underwent a questionnaire and comprehensive teeth and oral mucosa examination by a team of qualified and uniformed trained dentists. Oral clinical mirrors and community periodontal index (CPI)-type millimetric probe clinical data were collected according to the World Health Organization (WHO) dental caries diagnostic criteria. In this cross-sectional study, a total of 309 subjects participated was surveyed. Results: The results showed that acid exposure was correlated with soft oral tissue injury rather than hard oral tissue in our survey. Besides, halitosis and age were positive associated with periodontal disease and use of dental floss reduced the risk of periodontal disease. After correcting for major factors, such as age, sex, smoking, drinking, and chewing areca, acid exposure was still statistically related to periodontal disease in LA (loss of attachment) index by 3.27-fold (p = 0.00, CI 1.69 - 6.34). Conclusion: This study showed that occupational acid exposure during acidic solution work was an independent risk factor for periodontal disease. It is important to strengthen occupational hazard control, educate workers on oral disease and related factors, and raise the awareness of oral hygiene.
