Self-reported occupational health problems among Libyan dentists

To investigate the prevalence of the most common occupation-related health problems as well as factors associated with their incidence among dental practitioners.

A cross-sectional, questionnaire-based survey of Libyan dental practitioners. Participants provided information regarding their experience of occupationally related problems they encountered over the past 12 months which included inquiries about musculoskeletal pain, percutaneous injuries, allergy, eye and sight problems, and hearing problems.

Musculoskeletal problems were the most frequently reported (48.2%), followed by percutaneous injuries (35%), eye problems (22%), allergy (11%) and hearing problems (7.6%). Musculoskeletal problems were significantly higher among dentists who work in private sector, full timer as well as those who prefer to work in a sitting position (p=0.021, 0.027 and 0.008, respectively). Practitioners with less than 5 years in service reported significantly higher percentage of percutaneous injuries (p=0.027) than their senior counterparts, whereas practitioners who spent more than 10 years in service were more likely to suffer from visual disturbances (p=0.033).

The findings of this study indicate that musculoskeletal problems and percutaneous injuries are the most commonly reported occupational health problems among dentists, whereas allergic reactions and hearing problems are the least reported ones.

Dentists should use alternate working positions to minimise musculoskeletal problems and adopt more effective strategies to prevent percutaneous injuries particularly among novices.
