Abstract
In order to investigate the oral health status including dental erosion, the authors had surveyed and oral examined 510 male workers, among whom 199 workers were exposed to acids and 311 were not exposed to acids, in a factory using acids during the period from November, 26 to 27 in 1992. @ES The obtained results were as follows: @EN 1. The positive rate of dental erosion between the acid exposed and non-exposed group didn’t show statistical difference. But the positive rate of degree 1 dental erosion by degree was statistically high in the acid exposed group(P<0.05). 2. The acid exposed group showed the higher positive rte of dergree 1 dental erosion in lower incisor by site(P<0.01) 3. To the average number of eroded teeth, the acid exposed group showed more degree 1 eroded teeth in lower incisors than the non-exposed(P<0.05). 4. Although the rate of dental erosion was increased according to the increase in tenure in both exposed and non-exposed group(P<0.05), there was no difference in rate of the dental erosion by site among the same tenure group. 5. In the acid exposed group, the rate of dental erosion between protective mask wearer group and non-wearer group was not statistically different, but upper incisors of the protective mask wearer group showed lower rate of dental erosion by site(P<0.05). 6. The postive rate of periodontal disease was higher in the acid exposed group(P<0.01).
