Abstract
This research is based on self-filling survey which 656 dental hygienists who work in, seoul, the metropolitan area, jeon-buk area participated on July 2006 through August 2006. This survey was analyzed the relationship between the subjective symptoms(6 types) and outdoor air quality($O_3,\;NO_2,\;CO,\;SO_2,\;PM_{10}$) As follows analyzed results. The health condition of dental hygienists were "Feel Good" more than 50% in last month. The experience the symptoms level is higher then non-experience level in "Dry eye, itch, smarting", "Headaches", "Fatigue and sleepiness", "Red eye", "Hypersensitivity", "Dorsalgia, omarthralgia, cervicodynia". We anticipated that the more experience the subjective symptom the more likely it is that outdoor air quality will be high rate level. But we could not find the uniformity in metropolitan-area and seoul-area. In the case of jeonbuk area, the group's pollution density levels which experienced the subjective symptom were appeared high rate than inexperienced group except $SO_2$. It probably comes from sensibility for an air pollution in this area. Dental hygienists who work in jeonbuk area have an unusual sensibility for an air pollution because outdoor air quality of jeonbuk area was rule good rather than others area. especially $SO_2$ was revealed out even though low rate level in inexperienced group it is that the number of cars in jeonbuk area is increasing rapidly.
