INTRODUCTION: Dentists are exposed to various hazards due to their occupation. Identifying the most prevalent ones is required to develop preventive measures and coping strategies in order to reduce the effect of such hazards in the future. OBJECTIVES: to assess the prevalence of the different occupational hazards among the Ministry Of Health dentists, in Alexandria. MATERIALS AND METHODS: A sample of 900 dentists working in the different Ministry of Health facilities was randomly selected from the eight health districts of Alexandria governorate. A final sample of 750 dentists participated in the study with response rate of 83.33%. They were asked to complete a structured questionnaire, specially designed for the study, in order to assess their exposure to the different occupational hazards. RESULTS: Most of participants suffered from stress (85.9%), followed by musculoskeletal disorders (85.6%) and 63.9% experienced a type of percutaneous injury. Furthermore 51.3% were exposed to radiation hazards, 44.4% and 42.66% were exposed to eye injuries and chemical hazards, respectively. The least prevalent hazard was hearing impairment where it was reported by only 8.8% of the study participants CONCLUSIONS: Rheumatoid arthritis is an important risk factor for alveolar bone loss. The treatment of the RA induced rats with fish oil not only prevented the alveolar bone resorption and stimulated new bone formation, but also reduced relatively the level of rheumatoid factor in the blood
