Abstract

Introduction: Dentistry involves significant exposure to biological, physical, and chemical hazards. Early awareness is essential for developing safe clinical practices. Objective was to assess and compare the knowledge of occupational hazards among dental students and interns across different academic levels.

Materials and methods: A cross-sectional study was conducted among 241 dental students and interns at a private dental college in Chennai. Data were collected via a validated 10-item Google Forms questionnaire. Statistical analysis was performed using SPSS Version 27, utilizing descriptive statistics and the Chi-square test (p < 0.05).

Results: The cohort was predominantly female (75.1%). Significant associations between academic year and knowledge were found in 9 of 10 domains (p < 0.001). Fourth-year students showed the highest awareness of infectious diseases and radiation risks. However, musculoskeletal disorders (MSDs) was the only domain that failed to reach statistical significance (p = 0.061), with a majority of students across all years underestimating ergonomic risks. Misconceptions regarding thyroid collars for radiation protection were also widespread.

Conclusion: While clinical progression improves awareness of biological and radiation hazards, a universal deficiency exists in ergonomic and chemical safety knowledge. Integrating practical ergonomic workshops and safety protocols into the curriculum is vital to protect the health of future dental professionals.
