The purpose of this study was to examine whether senior simulation would bring any positive change to the attitude of dental hygiene students toward the elderly. The experimental group consisted of 58 dental hygiene students at a college. The experimental procedure was to do activities for 40 minutes wearing aging simulation suit. Self administered questionnaires were used to ask the attitude toward the elderly after senior simulation. The data were analyzed with SPSS program. General and aging related characteristics of subjects were analyzed through descriptive statistics. To testify the differences of the attitude after senior simulation, paired t-test was used. An experiment was conducted from May 27 to June 14, 2012, and the findings of the study were as follows: 1. There wasn't any perfect positive change in the overall attitude of the students toward elderly people after senior simulation, but their attitude got a little more positive whereas they took a neutral attitude in the past; 2. The students who had ever lived with elderly people under the same roof and who had ever received education related to the elderly underwent a more positive change in their attitude toward the elderly; 3. To what extent senior simulation was helpful for the understanding of the elderly was checked, and the majority replied that it was very useful or useful for the understanding of their physical aspects. The findings of the study confirmed that senior simulation didn't change the overall attitude of the students toward the elderly in a positive way yet brought about some positive changes in part. Therefore senior simulation is expected to be one of significant educational programs that could encourage students to have a better physical understanding of the elderly, to take a more positive attitude to them and to provide them with quality dental service.

Objectives : The purpose of this study is to investigate the effect of oral health education conducted by a dental hygienist in order to provide some information on intensive oral health education to elementary school students. Methods : Subjects were the students of J and M elementary schools in Seoul from October 28 to November 16, 2011. Oral health education was provided by a dental hygienist, and then they took the PHP test again to verify the effect of the oral health education. Results : Concerning changes in PHP scores after the oral health education, the scores of the students dropped from 2.34 in the pretest to 1.85 in the posttest(p<.001). As to changes in PHP scores by grade after the oral health education, the third graders and sixth graders got 2.40 and 1.36, respectively. Regarding satisfaction level with the oral health education, they got 4.07 out of five points. Among the items of satisfaction with the oral health education by grade, there were significant gaps in a change of toothbrushing method(p<.001) and a change of dietary control(p<.001) by grade. Conclusions : The finding of the study showed that both the third and sixth graders had less score in the PHP test and credibility to the effectiveness of the oral health education by the dental hygienist.

Objectives: The purpose of this study is to improve awareness of male dental hygiene by investigating the dentists' perception of male dental hygienists' image and work performance in clinical practice. Methods: The participants were 102 dentists who agreed to participate in this study. They completed- a self-administered questionnaire survey available on a website. The questionnaire comprised 26 questions, with each item scored on a 5-point Likert scale. Results: The male dentists perceived that with an increase in the experience of male dental hygienists would be willing to pay more than for female dental hygienists. In the case of male dentists, male dental hygienists perceived that they would feel stressed in a women-centered work environment. Additionally, it was found that dentists who had experience working with Male dental hygienists responded more positively to work performance awareness than had no experience (p<0.05). Conclusions: Active employment of male dental hygienists in clinical practice, could positively change dentists' perception of male dental hygienists.

In spite of appropriate treatment of peri-implantitis, the peri-implant bone loss was keep going, the clinician should remove the osseointegrated implant. the conventional methods are like a extraction of natural teeth, and use of trephine drills. In these days, many exclusive instruments are invented by implant companies. these instruments can make easy, least invasive, less traumatic removal of osseointegrated implants. In generally peri-implant bone loss progress steadily less sign and symptoms that the patient do not want to remove their implants. However, the failure of dental implant is big burden to clinicians and also patients. In the dental implant treatment, there is no 'failure' but only is 'replacement' or 'change'.

Nowadays, additive manufacturing (AM) technology is a promising process to fabricate complex shaped devices applied in medical and dental services. Among the AM processes, a DLP (digital light processing) type 3D printing process has some advantages, such as high precision, relatively low cost, etc. In this work, we propose a simple method to fabricate precise dental models using a DLP 3D printer. After 3D printing, a part is commonly post-cured using secondary UV-curing equipment for complete polymerization. However, some shrinkage occurs during the post-curing process, so we adaptively control the UV-exposure time on each layer for over- or under-curing to change the local shape-size of a part in the DLP process. From the results, the shrinkage amounts in the post-curing process vary due to the UV-dose in 3D printing. We believe that the proposed method can be utilized to fabricate dental models precisely, even with a change of the 3D CAD model.

This study analyzed the change in the rater reliability based on the student's practice evaluation process conducted at Yonsei University College of Dentistry. Through this, we suggest the significance of the rater calibration training in the student's practical evaluation of dental college. Nine professors from the department of Conservative Dentistry, Yonsei University College of Dentistry, analyzed the results of class II restoration cases twice in 2017 and once in 2018. Intra Class Correlation (ICC) which is a statistic used to determine the consistency of raters with three or more scores, was also calculated. ICC values increased as raters participated in rater calibration meetings and grading experiences. This shows that the rater reliability is related to the grading experience and feedback from calibration meeting. Based on the results of previous studies that grading experiences and rater calibration training can cause a meaningful change in rater behavior, we propose to conduct rater calibration training to ensure the evaluator reliability.

The purpose of this research is to provide the basic information for the development of dental healthcare system's expertise and spatial composition in diverse dental spaces in Korea according to dental specialist system enforcement. Literature review of dental expertise especially dental specialist system and investigation on current status of spatial composition of dental spaces have been conducted. After the review, the spatial composition with field survey and architectural drawings of selected dental spaces have been analyzed. The result of this study is arranged with three points. First of all, the main clinical dental spaces are the dental school's dental hospital, dental department in medical center/hospital and private dental clinic in Korea. The second one is that dental school's dental hospital had differentiated to 10-11 departments in 1970-1980's and dental department in medical center/hospital has been changing to dental hospital with 5-7 departments in 2010's, and dental clinic is changing to specific dental clinic according to dental specialist system in 2018. The third one is that spatial composition is related with dental expertise at diverse levels. Spatial composition in dental school's dental hospital had been highly differentiated with dental expertise, dental department in medical center/hospital is partially subdivided with dental specialist system, but that of dental clinic is not changed according to dental specialist system. In addition to current spatial composition according to dental expertise, it is necessary to analyze the change of spatial composition with diachronic methods to develop the dental healthcare system.
