Background: Occupational hazards in dentistry biological, chemical, physical, ergonomic and psychosocial pose significant risks during undergraduate training. We assessed knowledge, attitudes and practices (KAP) regarding occupational hazards among undergraduate dental students to identify gaps that can be addressed through education and policy. Methods: A cross-sectional survey was carried out at the Institute of Dental Studies and Technologies between 15 December 2025 and 30 January 2026. A structured, self-administered questionnaire (six sections: demographics; knowledge; attitude; practice; domain-specific awareness; training/need assessment) was completed by 453 students. Descriptive statistics (frequencies, percentages) summarized KAP; only fully completed questionnaires were included. Results: Of 453 respondents, 311 (68.6%) were female; 150 (33.1%) reported prior formal training on occupational hazards. Knowledge was moderate: most students recognised that dentistry involves biological/chemical/physical hazards (78.4%) and the cumulative risks of X-rays (84.5%); however, awareness was lower for chemical hazards (formaldehyde 59.0%; mercury 65.8%), with notable “don’t know” responses. Attitudes were strongly positive 87.9% agreed occupational hazards are a serious concern and 85.7% endorsed PPE use yet 81.9% considered undergraduate training insufficient. Self-reported safety practices were generally high for infection control (87.0% “always/often”) and biomedical-waste disposal (89.2%), but only 53% always used protective eyewear during curing. High prevalences of work-related ill-health were reported: musculoskeletal disorders 52.1% (shoulder pain most common), psychological stress/burnout 70.2%, and glove-related irritation/latex allergy 64.7%. Importantly, 88.5% expressed willingness to attend structured occupational-safety workshops. Conclusion: Undergraduate dental students showed positive attitudes and generally good safety practices, but notable gaps in formal training and knowledge especially regarding chemical hazards and ergonomics remain. High levels of musculoskeletal problems and stress highlight the need to integrate structured occupational-safety education, practical training, and wellness support into the curriculum.
