Abstract

BackgroundAcid 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.MethodsFrom 4 acidic solution factories, a total of 309 subjects (157 in control and 152 in exposed group) was enrolled. All participants competed oral examinations and self-report questionnaire, including the decayed, missing, and filled teeth (DMFT) index, community periodontal index (CPI), loss of attachment (LA) index, and tooth erosion. Multivariate logistic regression analysis was used to determine the association between the acidic solution exposure and oral health.ResultsThe results showed that acid exposure was correlated with soft oral tissue injury rather than hard oral tissue in our survey. In the multivariate model (adjusted for sex, age, worked years, education level, mouthwash use, dental floss use, tooth brushing, mask use, smoking, drinking, chewing areca and dietary habits with acidic foods), significant relationships of acid exposure with LA score were observed (OR = 2.32, 95% CI 1.03–5.26). However, the presence of acid exposure was not significantly associated with tooth erosion, DMFT, and CPITN.ConclusionOur study highlighted that occupational acid exposure was an independent risk factor for periodontal health, especially LA. It is important to strengthen occupational hazard control, educate workers on oral disease and related factors, and raise the awareness of oral hygiene.

Highlights

  • IntroductionAcid 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

  • 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, such as respiratory irritation [1], oral lesions, periodontal disease [2], tooth erosion [3], and may even increase the risk of cancer [4,5,6]

  • Results from our study showed that strong inorganic acids, such as hydrochloric acid, nitric acid, or sulfuric acid, used in industrial processes have a positive association with loss of attachment (LA)

Summary

Introduction

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. Acidic solution work generally refers to any work where workers may be exposed to acidic substances or related derivatives. 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, such as respiratory irritation [1], oral lesions, periodontal disease [2], tooth erosion [3], and may even increase the risk of cancer [4,5,6]. Common, are important health problems that tend to be ignored
