Purpose: It is intended to raise awareness of importance of protective equipment and necessity of safety education by examining the actual condition of measures to deal with accident, occurrence of injury, whether safety education is received or not, the actual condition of wearing protective equipment, and working environment of dental lab and dental technician. Methods: A self-administered survey was conducted for a total of 150 dental technologists. A chi-squared test and independent-samples t-test was carried out by using SPSS WIN Program (version 12.0) in order to analyze the actual condition of safety education according to work experience and position and whether injury occurred according to whether to wear protective equipment. Significance level was 0.05. Results: With regard to whether injury occurred according to whether safety education was received, there was 'receiving the safety education-injured (71.8%)', 'not receiving the safety education-injured (79.7%)', 'receiving the safety education-not injured (28.2%)', and 'not receiving the safety education-not injured (20.3%)'. The statistical results of injury occurrence according to safety education were not significant. With regard to whether to be injured according work experience, there was 'less than 10 years-injured (68.4%)', 'less than 10 years- not injured (31.6%)', '10 years or above-injured (89.1%)', and '10 years or above-not injured (10.9%)'. The statistical results of injury occurrence according to work experience were significant (p<0.001). Conclusion: Dental lab and specialized agencies should continue to be interested in periodic safety training, recommending wearing protective equipment and personal protective equipment support and so on.

Purpose: This study was conducted to verify the effects of self-esteem and critical thinking disposition on dental laboratory technology students' field practice stress. Methods: The subjects of the study were 198 dental laboratory technology students with clinical practice experience located in Gyeongsangbuk-do and Gyeongsangnam-do. The collected data were analyzed by t-test, ANOVA, correlation analysis, and linear regression analysis using IBM SPSS Statistics ver. 22.0 (IBM). Results: The average self-esteem, critical thinking disposition, and field practice stress scores were 3.76, 3.50, and 2.40, respectively. There was a significant correlation between self-esteem, critical thinking disposition, and field practice stress. It was found that the higher the self-esteem, the lower was the field practice stress. On the contrary, among the sub-items of critical thinking disposition, when intellectual fairness increased, the field practice stress decreased; however, when healthy skepticism increased, the field practice stress increased. Conclusion: Self-esteem and critical thinking disposition were both found to have a substantial effect on field practice stress. Therefore, various educational programs need to increase self-esteem and cultivate critical thinking skills for a successful field practice and field practice stress relief of laboratory technology students.

Purpose: The purpose of this study was to conduct a cost accounting of implant prosthesis according to the fabrication activities. Methods: In this study, the cost price of implant prosthesis fabrication activities was calculated by the bottom-up costing approach for material and labor cost and the top-down costing approach for expenses and other. Results: The total cost price was estimated to 220,000 ~ 310,000 won per one implant prosthesis. By product, the screw type was estimated to 220,000 ~ 230,000 won, and when the stent and tray were included, it was 260,000 ~ 270,000 won, which increased about 40,000 won. And, the cement type with more material and labor time was estimated to 250,000 ~ 260,000 won, and when the stent and tray were included, it was about 300,000 won. Conclusion: In terms of the fabrication cost ratio by items, it was shown that material cost and labor cost accounted for about 40% and 30% of the total cost structure for resin case, respectively, which was the opposite for porcelain. It was shown that expenses and general administrative expenses accounted for about 15%, and profits were about 11% ~ 14% in both cases.

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.
