Dental Erosion and Sulfuric Ion Exposure Levels in Individuals Working with Sulfuric Acid in Lead Storage Battery Manufacturing Plant Measured with Mouth-rinse Index

Abstract

To investigate dental erosion in employees working with sulfuric acid at a lead storage battery manufacturing plant and level of personal exposure to sulfuric ions, we measured sulfuric ion concentrations in the mouth rinse of those employees. We also measured exposure levels from air samples obtained from 2 employees from the same plant who did not work with sulfuric acid using a portable air sampler. At the same time, we collected and compared their mouth rinses with those from other employees. More specifically, we measured and compared sulfuric ion, calcium, and magnesium concentrations, along with pH levels from the mouth rinse of these two groups. Positive correlations were found between sulfuric ion and calcium concentrations (r‫,16.0ס‬ pϽ0.005), calcium and magnesium concentrations (r‫,16.0ס‬ pϽ0.005), Ca/Mg and calcium concentrations (r‫,46.0ס‬ pϽ0.005), and sulfuric ion and magnesium concentrations (r‫,55.0ס‬ pϽ0.005). Negative correlations were found between sulfuric ion concentrations and pH levels ‫,13.0מס‪(r‬‬ pϽ0.01), and magnesium concentrations and pH levels ‫,23.0מס‪(r‬‬ pϽ0.01). This suggests that mouth rinse from employees working with sulfuric acid could function as an indicator of sulfuric ion concentration in the work environment. Furthermore, this could lead to the development of a more accurate indicator of individual exposure.

Not carious lesions: the challenge of the multidisciplinary diagnosis

“…Reports from specialized literature show that the occupational exposure to the acid substances, in its various physical forms (gases, vapors or mists), constitute important factor of risk to buccal pathologies, observing consistent results related to the dental erosion (5,17,18).

Erosão dental ocupacional: aspectos clínicos e tratamento

“…Suyama et al, 17,18 verificaram maior concentração de erosão nos dentes anteriores inferiores de profissionais expostos ao ácido sulfúrico. O mesmo grupo de pesquisadores publicou um estudo avaliando bochechos coletados de trabalhadores que lidam com este ácido a…”

“…12 Tais ácidos podem significar efeitos irritantes nos tecidos mucosos membranosos e epiteliais além de efeito químico corrosivo nos dentes, conhecido como erosão dental. 17,18 Algumas características clínicas representam a erosão dental causada por ácidos industriais e a diferem das causadas por alimentos ácidos e ácidos intrínsecos. O quadro 2 descreve detalhes que auxiliam o diagnóstico diferencial.…”

“…Entretanto, sugeriram novos trabalhos para maior acurácia da metodologia. 17,18 A acidez dos vinhos varia entre 3.0 e 3.8 o que justifica que exposições de longo prazo a esta bebida podem resultar em erosão dental severa. Relata-se que provadores profissionais de vinho suecos experimentam de vinte a cinquenta tipos diferentes de vinho por dia e trabalham cinco dias por semana.…”

“…Assim, a perda dos tecidos duros dos dentes expostos a essas condições tende a ser maior de quando o desgaste é fisiológico e podendo, em alguns casos, apresentar destruição severa e desfigurante dos dentes (AMARAL et al, 2012;SUYAMA et al, 2010).…”
