Introduction: Occupational exposure to acids has been described in association with oral health, which is explained by the high irritant and corrosive acid effects that damage the enamel structure, cause inflammatory and immune reactions, and reduce the salivary pH, which can also compromise resistance to infections in oral cavity. So, this study was conducted to access the dental erosion and afford them the necessary treatment. Aim: The aim of this study was to evaluate the association between occupational health behaviors and occupational dental erosion in the employees of battery company, Bengaluru, Karnataka, India. Materials and Methods: A case–control study was planned among the workers of battery company in Bengaluru City. Total 362 subjects were selected for the study, among which 181 were cases and 181 were controls. The data were collected by administering a questionnaire, which included demographic data, years of experience, and oral hygiene practices. The dental erosion was assessed according to recommended diagnostic criteria of Smith and Knight Tooth Wear Index. Results: A total of 35.2% of the subjects had dental erosion in the age of 50–59 years. Comparison of dental erosion among the age-group revealed a statistically significant difference (P < 0.00). Approximately 14.5% cases and 1.75% of the controls had at least one tooth surface with dentine, which was statistically significant (P < 0.00). Conclusion: This study documents the association between deterioration of the oral health status and a hazardous workplace environment. Findings pointed to the need of establishing appropriate educational, preventive, and treatment measures coupled with efficient surveillance and environment monitoring for the detection of acid fumes in the workplace environment.
