Background: A greater understanding of impact of occupational dental erosion on oral health‑related quality of life (OHRQoL) will sensitize both employee and employers to adopt strict protective measures for oral health. The research aimed to determine the relationship between occupational dental erosion and OHRQoL among battery and other factory workers in Bengaluru, India.

Materials and Methods: This cross‑sectional comparative study enrolled a total of 400 workers. Structured proforma assessed information on sociodemographic details, oral hygiene practices, adverse oral habits, and work‑related practices. OHRQoL was determined using oral health impact profile‑14 (OHIP‑14). Dental erosion was measured using Smith and Knight’s tooth wear index modified by Millward et al. 1994 scoring system. independent t-test, Mann–Whitney U-test  and Spearman’s correlation was performed. P < 0.05 was considered statistically significant.

Results: The mean age of the participants in the study and control groups was 43.11 ± 8.02 and 45.93 ± 6.16 years, respectively. Less than half of the participants in the study group had positive behavioral work practice. The prevalence and severity of dental erosion was significantly higher in study group (39.5%) than control group (11.5%). Mean OHIP‑14 score was significantly lower in study group (23.88 ± 0.88) than control group (26.06 ± 9.67). Dental erosion significantly correlated with work experience and OHIP‑14.

Conclusion: The findings highlight the impact of occupational dental erosion on OHRQoL. Measures to enhance occupational safety thereby reducing exposure to occupational hazards are needed.
