Abstract
Background: Dental nurses and dentists were constantly exposed to a number of specific
work-related health risk factors which develop and intensify with years. Awareness regarding
these work-related health risk factors and implementation of preventive health care measures
could provide a safe work environment for all dental nurses and dentists. Aim of the study: To
assess the work-related health risk factors among dental nurses and dentists and preventive
health care measures applied among dental nurses and dentists. Research design: A descriptive
design was utilized. Sample: Convenience sample of 50 dental nurses and 150 dentists were
included in the current study. Setting: This study was conducted at the dental clinics at faculty
of oral and dental medicine, Al-Kasr Al-Ainy Hospital. Tools of data collection: Three tools
were developed, tested for clarity and feasibility: a-Socio-demographic data sheet, b-Workrelated
health risk factors questionnaire, and c-Structured observational checklist. Results: The
most common work risk factors prevailing among dental nurses were emotional exhaustion
(82%), low back pain (76%) and latex allergy (62%) and the most common work risk factors
prevailing among dentists were percutaneous exposure incident (100%), emotional exhaustion
(100%) and low back pain (93.3%). Also, statistically significant negative correlation (r=-
0.274, at p = 0.045) between the incidence of chemical health risk factors and application of
chemical preventive measures among dental nurses. A statistically significant negative
correlation (r=-0.177, at p = 0.030) between the incidences of mechanical health risk factors
among dentists and application of mechanical preventive measures. Conclusion: The studied
dental nurses and dentists exposed to many work-related health risk factors as latex allergy,
percutaneous exposure incidents, low back pain and emotional exhaustion related to
inappropriate application of preventive health care measures. Recommendation: Raise
awareness of dental nurses and dentists about work-related health risk factors, design and
implement health education program for preventive health care measures.
