OBJECTIVES: The aim of this study was to compare short-term and medium-term effects of gingival index (GI) and dental plaque index (PI), according to the tooth position through the oral hygiene education in the diabetic youth. METHODS: The total number of participants were 31 diabetics and 87 controls in the city of Daegu. Oral examination and professional oral hygiene care were performed among the 31 diabetic youth who consented to the study at the first visit. The professional oral hygiene care consisted of the tooth brushing method, oral prophylaxis, scaling, fluoride application, sealant and dental auxiliary education. We collected the data from all participants for the identification of oral condition at 2 weeks and 3 months. The #11, #14, #16, #31, #34, #36 teeth were selected for the measurement of the oral hygiene conditions. GI and PI were used for oral hygiene scores. The data was analyzed with SPSS 18.0 program. RESULTS: Both GI and PI were significantly decreased in the treatment group of the 31 diabetic youth in comparison to the controls, by tooth position compared to the baseline (P<0.001). In particular, GI measurements constantly decreased upto 3 months and the PI measurements decreased upto 2 weeks and increased slightly from 2 weeks to 3 months. In the GI measurements, the decrement of #14 was the highest (48.4%) and #36 was the lowest (25.2%) among all teeth. In the PI measurements, the decrement of #14 was the highest (45.5%) and #16 was the lowest (19.8%) among all teeth. In the control group, PI increased on all tooth positions, and GI increased on some tooth positions. CONCLUSIONS: The program of professional oral hygiene care in the diabetic youth has improved the oral health care when compared to the controls. We suggest that the sites where oral hygiene is more difficult to control have more oral hygiene education than the other sites.

OBJECTIVES: This study was conducted to investigate the awareness of the students currently attending dental colleges/schools in Seoul regarding the scope of work done by a dental hygienist (DH) and a chair-side dental assistant (DA).METHODS: A direct questionnaire survey was conducted among 950 students who currently attend dental colleges/schools in Seoul. We were able to use a total of 458 samples for final analysis after excluding inappropriate ones. The contents of this structuralized survey included the obligation of proper name badge use for dental health care personnel, the legal work scopes of a DH and a DA in accordance with the revised execution of the ‘Legal Acts on Medical Technicians’, and the inclusion/exclusion of such contents from dental colleges/schools curricula. The results were statistically analyzed via the IBM SPSS Statistics 25.0 software.RESULTS: Many subjects were aware of the difference in scope of work performed by a DH and a DA (P < 0.001), but not their legal obligation to wear appropriate name badges in accordance with the ‘Proposal for the Establishment of the Name Badge Standards for Healthcare Practitioners'. The subjects generally showed higher comprehension of the scope of work performed by a DH (74.3%) than that performed by a DA (57.7%). Without the presence of any corresponding curriculum, accurate responses tended to increase with the students' seniority. Most students (94.4%) agreed with the need to include a class that teaches the scope of work performed by a DH and a DA in their school curricula.CONCLUSIONS: We have found that education regarding ‘Name Badge Standards for Healthcare Practitioners’ and classification of a dental assistant's scope of work is lacking in the existing curriculum. Therefore, it is necessary to establish additional curriculum.

PURPOSE: The aim of this study was to assess the degree of awareness and actual practice of dental practitioners regarding infection control during prosthodontic treatment. MATERIALS AND METHODS: Study participants were composed of dentists, dental hygienists, dental technicians working at dental university hospital, general hospital, dental hospital and dental clinics in Daejeon, Korea (n=126). The questionnaires included the data on general characteristics, education, awareness and practice of infection control procedures during prosthodontic treatment through personal self-administration survey. Awareness and practice were measured by Likert scale ranging from 1 to 5. Statistical analysis was done by one-way ANOVA. Influence of awareness on practice was estimated by regression analysis. RESULTS: 27.7% of the respondents answered that the infection control education regarding prosthodontic treatment is insufficient. The mean value of awareness and practice of infection control during the prosthodontic treatment were 2.72 +/- 0.80, 1.58 +/- 0.88, respectively. The mean value of practice who answered that had education curriculum at college was 1.62 +/- 0.9, and 1.31 +/- 0.49 who did not. The mean value of awareness who equipped guideline was 3.01 +/- 0.9, and 2.56 +/- 0.70 who did not. CONCLUSION: 1. The respondents who received the infection control education by college curriculum showed higher degree of practice than the respondents who did not. 2. The respondents who have appropriate infection control guidebook in their workplace showed higher degree of awareness than the respondents who did not. 3. There was a correlation between the awareness and practice of infection control during prosthodontic treatment; the degree of awareness becomes higher, so does the degree of practice. 4. During the prosthodontic treatment, the degree of practice was lower than the degree of awareness on infection control.

This study's aim was to investigate their opinions to improve the educational system for dental hygienists on the basis of their duties as dental hygienists. The qualitative study was conducted among 19 dental hygienists at Daejeon, Korea from July to August 2016. Two researchers followed each subject for working hours in a day and recorded all the tasks and time to take for each task. After one day, the researchers met each subject and conducted face-to-face interviews to investigate the opinions about the dental hygiene curriculum and national board examination. The main duties recognized by more than half of the subjects were oral disease prevention including scaling and dental treatment assistance. The subjects' minority opinion about the main duties included radiography, impression taking, dental implant surgery assistance, orthodontic treatment, patient counseling, dental management and staff management, and oral health education. The most important tasks perceived by the subjects were prosthetic and implant impressions, scaling and implant surgery assistance. The subjects' minority opinion about the most important duties included patient counseling and making temporary crowns. The most difficult tasks answered by the subjects were prosthetic and implant impressions and dental implant surgery assistance. The subjects' minority opinion about it included patient counseling, scaling, and making temporary crowns. They mentioned that their curriculum in college was different from the actual work and the national board examination was not reflective of their real duties. We found out Korean dental hygienists had a lot of roles as dental assistants, dental business managers, and so on. We suggest that the law, curriculum and national board examination for dental hygienists should be revised to be able to reflect the reality of the clinical field.

CONCLUSIONDental manpower index is a good method to evaluate dental manpower resources.

To achieve an esthetic restoration, visualized information considering the facial aspect of patient is required. As for the reasons of esthetic failure, it could be explained by lack of communication and information such as horizontal, vertical and esthetic line. Therefore, it is important to deliver that the visualized information to dental technicians or other dentists for the success of esthetic treatment. This case report presents the process of visualizing esthetic information and designing the restoration using a digital diagnostic tool; Digital Smile Design.

PURPOSE: This study evaluated the usability of and satisfaction with two types of computer-aided design (CAD) software among users who had experience with dental implant CAD software and those who did not. MATERIALS AND METHODS: Dental technicians (n = 20) who had previous experience with dental implant CAD Software and students from the College of Dentistry (n = 12) who had never designed implant custom abutments were asked to evaluate two types of CAD Software, Exocad and Deltanine. In addition, the participants were asked to fill out a structured questionnaire (Section 1: Entering basic information and retrieving files; Section 2: Setting conditions before abutment design; Section 3: Setting abutment design; and Section 4: Overall satisfaction). For the statistical analysis of the collected data, Mann-Whitney U test was used (α = .05). RESULTS: The ease of design and satisfaction with the implant CAD Software, evaluated with respect to 21 statements divided into four Stages, were significantly higher for Exocad in both groups for Secion 1. For Sections 2 and 3, participants with experience evaluated Deltanine to be significantly better. For Section 4, both groups evaluated Exocad Software to be better. CONCLUSION: Overall, the Exocad Software was evaluated as having better usability and offering greater satisfaction. However, in terms of performance in the core of the design process, i.e. Sections 2 and 3, Deltanine was rated higher by the experienced users. Thus, if the user interface design parts are supplemented, Deltanine CAD Software could be put to a wider use in clinics.
