Purpose: This study studied and investigated the oral health behavior of students in the Department of Dental Technology at D College at D City. Methods: A self-administrated survey was conducted by students currently enrolled at the Department of Dental Laboratory Technology at D College (June 4, 2015 ~ June 12, 2015), and 320 copies that were available for statistical processing were statistically analyzed by using the SPSS 19.0 Program. Results: Among the survey respondents, 91.6% had experience of dental treatment. The highest response regarding the frequency of tooth brushing appeared to be 'twice' with 44.7%. The responses regarding the time of tooth brushing appeared to be highest for 'before sleeping' with 65.3%, which was followed by 'after breakfast' with 60.6%. To the question asking which areas are brushed during tooth brushing, the response of 'teeth, gum, and tongue' appeared to be highest with 44.4%. Among the respondents, 64.7% experienced scaling, however, the experience rate for scaling appeared to increase in proportion with the increase of class year (p< .001). Regarding the subjective feel for the importance of oral health and necessity of tooth brushing, the scores appeared to be both 4.56. However, the score appeared to be 3.27 regarding one's subjective perception of one's own oral health condition. Regarding one's subjective oral health knowledge level depending on gender, female students showed a meaningfully lower rate (3.12 points) compared to male students (3.29 points) (p< .05), and depending on class, the knowledge level appeared to be meaningfully higher along with the increase in class year (p< .001). The experience of receiving oral health education appeared to be 78.4%, and 88.8% of the respondents responded that there is need for oral health education, however, the intent to participate in an oral health education program appeared to be 56.6%.

Two diketones, 1-phenyl-1,2-propanedione(PD) and 2,3-butanedione (BD) were investigated as new visible light photosensitizers for a dental resin composite of bis-GMA in order to improve photopolymerization effect. And the photopolymerization efficiency of mixed photosensitizers, PD-CQ and DA-CQ, was studied. Photopolymerization effect of photosensitizers were compared with that of camphorquinone(CQ), the most widely used photosensitizer. The photopolymerization efficiency of bis-GMA containing the photosensitizer increased with irradiation time. The increase was in the order: BD < CQ < PD. The photopolymerization efficiency of this mixture was not so efficient as CQ or PD.

The purpose of this study was to furnish data for a new curriculum of the "Bachelor's Degree Course at Junior College" in Korea. Domestic three colleges and one university were selected for comparative analysis about curriculum of the dental laboratory technology. Moreover, three colleges and three universities were selected in Australia, Canada, and USA which are preferred highly on overseas employment by the korea students of dental laboratory technology. From the six colleges and four universities, number of subjects and credit hours on special study were acquired and compared. Between domestics, an agreement on special study were compared. Transferable subjects from korea to foreign were acquired. From the number of subjects and credit hours on special study comparing, following results were obtained. The results were as follows; 1. The ratio of the number of subjects and credit hours on special study were averagely 78.2% and 83.7% in domestic college, 70.8% and 69.7% in domestic university. 2. The ratio of the number of subjects and credit hours on special study in Canada was similar to domestic but those in Australia and USA were less than domestic. 3. Between domestics, an agreement of subjects and credit hours on special study were 81.2% and 84.2% in Catholic University of Busan, 72.2% and 76.4% in Daejeon Health Science College, 71.2% and 72.8% in Gwangju Health College University, 65.1% and 65.9% in Shin Heung College University respectively. 4. Transferable subjects from Korea to Australia or Canada was more than USA. Those to Australia was similar to Canada.

Purpose: This study aimed to determine dental technicians' job satisfaction levels and to assess its influence on turnover intention. Methods: We included 230 dental technicians who work within Seoul, Incheon, Daejeon, the Gyeonggi Province, and the Chungcheongnam-do Province. We carried out a self-reported survey using a structured questionnaire. Results: As a result of assessing the research subjects' job satisfaction level, we found that there was a significant difference in working hours and a dental-work continuing plan sphere (p<0.05). Achievement & self-realization factors, the human relation factor, and growth & development factors were reported to be major job satisfaction indices. The whole average of the job satisfaction level came to 3.11, thereby appearing to be relatively high. In analyzing the research subjects' turnover intention, there was a significant difference in age, task field, dental-work career, working hours, incumbency, and dental-work continuing plan sphere (p<0.05). The question average for turnover intention was 2.88. As a result of assessing a correlation between job satisfaction and turnover intention, a significant negative (-) correlation was found between job satisfaction and turnover intention. Thus, a higher job satisfaction level was observed to lead to a lower turnover intention. Conclusion: As a result of conducting a regression analysis in order to assess the influence of job satisfaction on a turnover intention, a working condition factor, a human relation factor, and a recognition factor each appeared to have a high impact.

Purpose: The purpose of this study was to evaluate the validity of digital models fabricated by difference optical source of non-contact 3D dental scanner. Methods: A master model with the prepared upper full arch tooth was used. Stone model(N=10) were produced from master model, and on the other hands, digital models were made with the 3D dental scanner(Blue, white, red optical source). The linear distance between the reference points were measured and analyzed on the Delcam $Copycad^{(R)}$ graphic software. The results were statistically analyzed using the one-way ANOVA and Tukey's HSD test(${\alpha}=0.05$). Results: There were considerable differences in mean values between optical source within each color(blue, white, red), and this difference was not statistically significant(p>0.05). Conclusion : Three different color of dental scanner optical source showed clinically acceptable accuracies of full arch digital model produced by them. Besides, these results will have to be confirmed in further clinical studies.
