Objectives: The purpose of this study was to investigate the actual condition of bullying in the workplace by dental hygienists and to determine whether workplace bullying affects job performance. Methods: Data were collected from 308 clinical dental hygienists working in dental medical institutions located in the whole country. Frequency analysis, descriptive statistics, t-test, and ANOVA were performed using SPSS 23.0 for analysis. Results: First, the main targets of bullying in the workplace were senior dental hygienists (53.6%) and dentists (24.7%). Second, the number of turnovers was a significant influence on bullying and job performance according to general characteristics. Finally, the 'improper work environment' among the subfactors of workplace bullying had a negative effect on 'job performance' (p<0.001). Conclusions: Based on the results of the study, we reviewed the actual condition of bullying in the workplace and whether bullying in the workplace affects job performance in the workforce problem of dental hygienists. In this regard, the importance of prevention of bullying in the workplace was discussed.

Estimating by clinical index the efficacy of three cases, where chewing gum is mixed with nanoparticle containing chlorhexidine, where chewing gum doesn't contain neither of them, and where with chlorhexidine only, this study has come to the following conclusion. 1. The chewing gum with chlorhexidine and chlorhexidine nanoparticle has shown more reduction of plaque index and gingival index than that with no chlorhexidine. 2. There could be seen a difference between the gum with chlorhexidine and the gum with chlorhexidine nanoparticle. 3. The gum with chlorhexidine nanoparticle has shown less level of plaque index than that chlorhexidine, which difference was only slight. 4. The gum with chlorhexidine nanoparticle wasn't absorved any tooth coloring. To put these results together, it is proposed that mixing chewing gum with chlorhexidine nanoparticle can be an efficient application.

In order to develop natural anticariogenic agents, we investigated inhibitory effects of Areca catechu L. extracts on the acid production of Streptococcus mutans JC-2 and its cytotoxicity on NIH 3T3 fibroblasts were also examined. The results are as follows : 1. Major organic acid produced by Streptococcus mutans JC-2 were lactic acid and acetic acid, and their productions were decreased by additions of Areca catechu L. extracts. 2. Areca catechu L. extracts were showed noncytotoxicity on NIH 3T3 fibroblasts.

In its study, We investigated the effects of Areca catechu L on the growth and acid production of Streptococcus mutans JC-2 in broth system and the activity of glucosyltransferase. The results were summarized as follow; 1. The growth of Streptococcus mutans JC-2 was suppressed by adding Areca catechu L in broth system. Especially, its inhibitory effect was significant at 2,000ppm of concentration. 2. Areca catechu L decreased the acid production of Streptococcus mutans JC-2. Decrease of pH according to acid production was less in presence of Areca catechu L than in absence. 3. Areca catechu L exerted the inhibitory effect against glucosyltransferase activity form Streptococcus mutans JC-2.

Objectives: The purpose of the study is to investigate the relationships between multiple intelligence, academic self-efficacy, satisfaction with major in dental hygiene students. Methods: A self-reported questionnaire was filled out by 490 dental hygiene students in Jeonbuk from March to April, 2015. The questionnaire consisted of 119 questions of multiple intelligences, 28 questions of academic self-efficacy, 5 questions of satisfaction with major by Likert 5 scale. Data were analyzed by descriptive statistics, Pearson's correlation test, and stepwise multiple regression test using SPSS 18.0 program. Results: The students had the highest score in interpersonal intelligence(3.57) and the lowest in naturalist intelligence(2.66). There was a positive correlation between the multiple intelligences, academic self-efficacy and satisfaction with major(p<0.05). The impact of multiple intelligences on academic self-efficacy was influenced by logical-mathematical intelligence, intrapersonal intelligence, musical intelligence, bodily-kinesthetic intelligence, and linguistic intelligence(p<0.05). The variables that had an impact on multiple intelligences and satisfaction with major were interpersonal intelligence and intrapersonal intelligence(p<0.01). Conclusions: The development of multiple intelligences can enhance the satisfaction with the major, quality of education, academic self-efficacy in the dental hygiene students.

Objectives: The purpose of this study was to investigate comparison of the effectiveness on knowledge improvement before and after the oral health education focusing on foreign students. Methods: A self-reported questionnaire was filled out by 40 foreign students in Sun Moon University from June 2 to September 30, 2014. The experimental group had an online oral health education and the control group had an off line education. The questionnaire consisted of oral health(10 items), toothbrushing(10 items), dental caries(10 items), periodontal disease(5 items), tooth sensitivity(5 items), oral cancer(6 items), and smoking(5 items). The data were analyzed by SPSS Win 18.0 program. Results: Knowledge scores of online education increased to average 1.257 points, and that of offline education was average of 2.56 points. There were statistically significant results for toothbrushing, dental caries, periodontal disease, tooth sensitivity, oral cancer and TMD except for smoking in offline education group. Conclusions: This study suggests that the offline oral health education is more effective than online oral health education.

The purpose of this study was practiced to investigate factors affecting dental hygienists's stress. The results executed by percentage and Likert scale (on a scale of 5) producing a mean standard deviation, T-test, one way ANOV A and person correlation coefficient using SPSS according to purpose of study. The results of study were as follows: 1. Mean point of stress from administration system dental hygienists's was 3.49 2. The dental hygienists's job place was significantly related to stress from duty volume (p=0.000), stress from personal relation(p=0.028) and stress from atmosphere of job(p=0.000). 3. The dental hygienists's career was significantly related to stress from safe job. 4. The dental hygienists's grade in rank was significantly related to stress from pride ＆ self-conceit. 5. The number of colleague worked public health center was significantly related to stress from duty volume. 6. There is a significant relationship between stress from duty volume and stress from conflict of job(p〈0.01, r=0.280). There is a significant relationship between stress from dissatisfaction and stress from personal relationship(p〈0.001, r=0.396). There is a significant relationship between stress from pride ＆ self-conceit and stress from personal relationship(p〈0.001, r=0.423). There is a significant relationship between stress from personal relationship and stress from atmosphere of job(p〈0.001, r=0.662).
