This study was carried out in order to offer basic data available for forming the better oral health habit by closely examining a cause for industrial workers' tooth loss. It analyzed correlation in missing teeth with general characteristics, subjective oral health recognition, habit related to oral health, and oral symptom targeting 6,976 of production workers and office workers who work at 49 industrial places where are located in Gumi city of Gyeongsangbuk-do Province from June 1, 2009 to December 31, thereby having obtained the following conclusions. 1. The higher age group led to the higher ratio of missing teeth. The ratio of missing teeth was lower in a case of having been removed plaque than having not been removed plaque. 2. The ratio of missing teeth was high in a case of having dental caries and periodontal disease. The ratio of missing teeth was high in a case of having smoked in the past or in a case of smoking now. 3. The ratio of missing teeth was high in a case of having less toothbrushing frequency and in a case of not using dental floss or interdental brush. 4. The ratio of missing teeth was high when a tooth is throbbing and when tongue and cheek are throbbing in addition to pain and bleeding in gum. 5. The ratio of missing teeth was high in a case of having unpleasant bad breath. The above results are expected to be likely conducive to offering basic data necessary for developing the oral health educational program for industrial places that can promote and maintain workers' oral health, and for improving oral health program and system available for promoting and maintaining workers' oral health hereafter.

The purpose of this study is to investigate the effects of awareness of oral health on oral health status and oral health behavior with subjects of students in the middle school which is the important period when lifetime set of teeth is completed with eruption of the second molar tooth and complete set of permanent teeth, and provide the basic data for development of oral health program for adolescents. We examined oral condition and conducted the survey about students' awareness of oral health and behavior in the middle school located in JeonJu. As the results of oral examination, dental caries and malocclusion were higher in female students and periodontal disease was higher in male students (p < 0.038). There was no significant difference in awareness of oral health between male and female students. However, M = 4.08 out of 5 point scale, which was high. For oral health behaviors, female students (M = 4.508) was higher than male students (M = 4.257) in the question of 'I visit the dental office when my gums are bleeding'. Female students (M = 4.547) was higher than male students (M = 4.333) in the question of 'I use the dental floss after brushing my teeth'(p<0.05). Awareness of oral health gave the significant effect on the oral health behavior at 95 % confidence level. Therefore, the education for oral health behavior is required to improve oral health and studies are needed to present the development of program for awareness and knowledge of oral health affecting behavior.

The purpose of this study was to examine correlation between smoking and gingivitis in boy students targeting 281 students in the 2nd grade for vocational boys' high schools where are located in Cheongju city. As a result of carrying out questionnaire research and oral examination, the following conclusions were obtained. 1. The smoking-experience rate in subjects of this study accounted for 59.4%. The current smoking rate was indicated to be 41.3%. Students' average gingivitis prevalence accounted for 61.5%. Out of those students, the students with experience of smoking accounted for 44.8%. The average gingivitis index was $0.20{\pm}0.27$. Out of those students, the students with experience of smoking were indicated to be $0.29{\pm}0.31$. 2. In case of having experience of smoking, the probability of having gingivitis was high(p = 0.000). The more drinking experience led to the higher gingivitis prevalence(p = 0.010). 3. In the multi-variate analysis, a case of gingivitis prevalence was higher in the group with experience of smoking by 5.5 times(p = 0.000) compared to the non-smoking group. A case that the smoking volume for a day is over 6 pieces was higher by 8.4 times(p = 0.000) compared to the non-smoking group. A case of being over 25 months in the smoking period was higher 13.2 times(p = 0.000) compared to the non-smoking group.
