Workers want to protect workers from the oral health disability that can occur in labor and working conditions in the industry. Therefore, in order to maintain and promote oral health status of workers, health checkups and oral examinations were conducted for workers since 1995. However, since general oral examinations only report results, efforts for oral health education and oral disease prevention are not made. Therefore, it is not enough to prevent oral diseases and improve oral health of workers. The purpose of this study was to analyze the use of brushing and oral care products for the prevention of oral diseases among workers in some large corporations in Korea. From August 9, 2017 to August 26, 2017, the work was conducted for workers in Ulsan Metropolitan City. Data were analyzed with frequency analysis, χ2-test analysis SPSS 21.0.(P<0.001). As a result of analyzing the experience of oral health education according to the demographic characteristics, it was found that the oral health education experience was increased with increasing age (P<0.001). Gender, education level, marital status, working style and oral care education experience were statistically significant. The subjects with experience in oral health education were the most likely to use oral care 52.5% (P<0.001). In order to maintain and improve the oral health status of workers in the workplace, oral health education for the prevention of oral diseases should be conducted periodically in the workplace.
