To assess the status of occupational hazards and their prevention among the practicing dentists in Chandigarh city, India. A closed-ended questionnaire was prepared to record demographic status, types of occupational hazards encountered, and status of measures used for their prevention. A total 113 out of 130 dentists completed the questionnaire and the response rate was 86.9%. Frequency tables were prepared and coefficient of correlation was computed to check correlation between different variables. Statistical significance was set at P < 0.05. The most common occupational hazard reported was injury from "sharps" (77%), out of which needle prick injury was the most frequent. Of the other occupational problems job related stress (43.3%), musculoskeletal problems (39.8%), and allergies (23.8%) from things used in dental clinics were most common. A reasonably high percentage of dentists were immunized against hepatitis-B virus (88.4%) and were following proper infection control measures and hospital waste disposal methods. Very few dentists were following the correct method of disposal of excess amalgam (11%) and measurement of radiation exposure (27.5%) within their clinic. Most of them (90.2%) were satisfied with their current working hours and job. Prevalence of occupational hazards among the studied group was high and certain preventive measures were not being followed properly. Therefore, there is a need to improve the knowledge of dentists regarding these hazards and their prevention.
