Traumatic dental injury is considered a public dental health problem because of a high childhood incidence, high treatment costs, and prolonged treatment time. Although management guidelines for traumatized teeth have been outlined, tooth loss following trauma is occasionally unavoidable. Here, we describe the successful interdisciplinary management of a traumatized central incisor in an 11-year old boy that was extracted because of a poor prognosis and restored by the autotransplantation of an immature donor tooth into the site. The patient underwent orthodontic treatment in order to close the donor site space and bring the autotransplanted tooth to an ideal position. Postorthodontic treatment radiographs and photographs revealed an esthetic and functional natural tooth replacing the lost tooth. The findings from this case suggest that autotransplantation offers unique advantages as a treatment modality for the restoration of missing teeth, particularly in growing children.
The purpose of this study was to evaluate the titanium castability (internal porosity) between pressure type casting machine & centrifugal casting machine with air-vent or not. Internal porosity is a well-known problem in dental titanium casting, resulting in inferior mechanical properties of dental restorations. To evaluate the castability, the square plate was chosen. 40 plate patterns($20{\times}20{\times}1.8mm$)were attached to funnel-shaped sprue. Then 20 plate patterns were attached air-vent. They were invested in titanium investment material and cast in a pressure type casting machine(20castings) and centrifugal casting machine(20castings). Each group were divided with air-vent(10castings) or not(10castings). The titanium castings were evaluated by radiographic photograph for the location of the internal porosities. The percentage porosity of each specimen was determined using standardized digital radiographs. The results were analyzed with analysis of variance and t-test for paired comparison between two groups.
Objectives: The purpose of this study was to investigate role·activity factors, ideal·value factors stress and stress amount relationship in clinical practice of dental hygiene students. Methods: The participate in this study were 231 dental hygiene department students. the survey was conducted from August 24 to September 30, 2018, using a structured questionnaire(1040460-A-2018-036). The collected data were compared and analyzed using a ANOVA and multiple regression. Results: The factors affecting the amount of stress were investigated. Role and activity factors stress in case of too much assignment, repeat simple and funtional work, ideal and value factors stress in case of utilized as a subsidiary work practice institution rather than clinical practice, lake of awareness that the training institution is a trainee. Conclusions: School institution and departments form organic relationships with industries. Uniform training guidance for each training institution does not help with diversity or creativity and problem-solving skills. It gives some autonomy to the training guidance of training institutions, also a clear standard for the contents of the training. we need a system that can provide and evaluate basic guidelines for what students can do in clinical practice.
This study was surveyed the knowledge and attitude toward the elderly in dental personnels, who play an important role in oral health of the elderly in the aging society, In order to arrange the basic data that is conducive to development in the mouth care of the elderly, the research was conducted from January 7 to February 14, 2008, targeting 270 dental personnels in Daejeon & Chungnam area, who are in charge of oral duties in the current clinic. As a result of analyzing so that questionnaire can be prepared with the self-administered questionnaire, the following results were obtained 1. The knowledge level on the elderly in dental hygienist was 13.47 marks out of 25-mark perfection. There was no difference in knowledge depending on job category and volunteer-work activity experience, And, there was no difference even depending on physical & physiological sphere, psychological sphere, and family & social sphere. 2. The attitude level toward the elderly in dental hygienist was 91.63 marks out of 150-mark perfection. Dental hygienist showed positive attitude in personality characteristic, emotional characteristic, and self-management ability by sphere, and showed statistically significant difference (p=0.011). 3. In case of having volunteer-work activity experience, the attitude level toward the elderly was 92.57 marks out of 150-mark perfection, A case of having volunteer-work activity experience showed positive tendency in emotional characteristic, self-management ability, and judgement-ability characteristic by sphere, And, the attitude toward family relation was indicated to be negative tendency, thus there was statistical significance(p=0.022). 4. As for the correlation between knowledge and attitude toward the elderly, dental hygienist was indicated to have high interest in the volunteer-work experience, the elderly education experience, and the elderly problem(r=0. 444). The knowledge and attitude toward the elderly had slightly positive correlation(r=0.155). Dental hygienists are being required gradually as the primary staff for the elderly people's dental care in the aging society. A continuous education is needed so that dental hygienists can have positive sight in understanding, knowledge, and attitude. And, the development in a mouth care program for the elderly in line with it is considered to be necessary.
Objectives: This study aims to alleviate dental hygienists' job stress caused by emotional labor, lower their turnover rate, improve the working environment, and offer better quality of services by understanding correlations among emotional labor, job characteristics, job stress, and turnover intention. Methods: A survey was conducted in the subjects with dental hygienists who were working at general hospitals, dental university hospitals, and private dental clinics located in Seoul, Gyeonggi, and Chungnam by the convenience sampling method from June 1 through 30, 2017, and the collected data were analyzed using by SPSS Windows Ver. 22.0 (IBM CO, Armonk, NY, USA) and AMOS 21. As the statistical analysis methods, convergent validity test, structural equation model analysis and model goodness of fit were conducted using independent samples t-test, one-way ANOVA, path analysis, and confirmatory factor analysis. Results: It turned out that the more dental hygienists' deep acting of emotional labor and the more their workload of job characteristics, the higher their job stress got, and that the higher their job stress, the higher their turnover intention got. Conclusions: As a method of lowering dental hygienists' turnover intention, they may resolve emotional disharmony with their own problem-solving method, but it is necessary to develop and support organizational culture for the improvement of working environment. Dental hygienists' organizations should implement the measures to minimize their turnover rate and job stress level by allocating appropriate workload.
A 26-year-old female patient with Down syndrome visited to recieve dental treatment under gnenral anesthesia 6 years ago. The patient had difficulties in oral examination, radiograph taking and laboratory test. The patient had congenital heart disease and medical consultation based on the echocardiography was provided by a cardiologist indicating that the patient could tolearte general anesthesia during dental treatment. And two times of general anesthesia were administered during a dental treament with the interval of 3 years and no postoperpative complicaton was reported. At the third dental operation, the patient had a relatively good condition and her prescreening test revealed no abnormalities. Without further consultation with a cardiologist, general anesthesia was administered to the patient. Anaesthesia was based on thiopental and ventilation of desflurane and $N_2O$ in oxygen via an endotracheal tube with an appropriate monitoring. During the maintenance of anesthesia, the blood pressure of the patient started to drop and the oxygen saturation also began to decrease. Consequently, the proceding operation was discontinued and also inhalation anesthesia was ceased. As the patient was recovered from anesthesia, her systemic conditions were alleviated. After the complete recovery of the patient, she visited the cardiologist, and the cardiologic test revealed her severe right ventricular dilatation. In the anesthesia of patients with congenital heart disease, information on their systemic conditions needs to be undated from the medical consultation, which assures the safety of treatment.
One of the problems facing in all modern dental hospitals is the much efforts, manpower and space are needed to effectively sort and stack patients' charts of the various dental departments. In addition, the storage and prompt arrangement of x-ray films is also a problem. Therefore, if dental charts as well as films could be computerized, it would be easier to store and keep them; by data basing, many space, manpower and cost would be saved: data could also be effectively managed for the purpose of academic researches. This would be an epoch -making event in the development of dental hospital management. The purpose of this study is to develop a dental information processing program, that will be used to store dental treatment records and digital image data using a new record media, the optical card. The patients' charts from the dental hospital were selected. The treatment records of the chart were put into the treatment data -recording area of the program, and the digital images of various dental x-ray films were made with a scanner. These data were stored in the optical card and analyzed to get the following results: 1. In this program it is possible to put treatment records and image data into and out from the optical card, and it is impossible to correct and delete all data recorded on the optical card. 2. All data in the optical card system can be searched and analyzed on database. 3. The resolution of image data stored in optical card is above 5.9 lp/mm. 4, All data of dental charts used as samples, stored to optical cards, occupies average 14%, In conclusion, with the development of the storage system using the optical card, a dental patient's life-time treatment record can be stored in one optical card and used as a substitute for the dental chart.
The purpose of this study is to analyze the clinical dentistry curriculum in Korea and Japan in order to review the application of integrated curriculum in the field. We collected the clinical dentistry syllabi for 2015-16 of the department of dental hygiene of Korea G University and Japan N University. Using the data from Korea, items that were duplicated and integrated were classified by the subjects covered in clinical dentistry. In addition, through case studies conducted in Korea and Japan, we analyzed and compared the credits, class hours, teaching methods, and evaluation methods, by subject. In Korea the total class hours in clinical dentistry, including clinical practice, was 1,095, and in Japan it was 1,104. In Korea, the syllabus covered by each department consisted of about 200 hours centering on theoretical lectures. In Japan, the integrated form of clinical dentistry was taught, and the instructions included all the contents of clinical dental study and also problem-based learning for approximately 100 hours. To strengthen the competence of dental hygienists as professionals, who are actively involved in dental practice, it is necessary to integrate the education contents of segmented clinical dentistry from the perspective of dental hygiene. It is also important to apply teaching methods that can help students improve their ability to solve problems.
Background: Dental hygienists undergo 3 or 4 years of college education, and dental hygienist education must receive continuous feedback through evaluation. The purpose of this study was to compare the educational performance of students from the Department of Dental Hygiene in 2018 with those from other departments in the healthcare field. Methods: We used data from the National Assessment of Student Engagement in Learning, conducted by the Korean Educational Development Institute in 2018. The survey data of 55 dental hygiene students and 60 healthcare students at K University were provided after excluding all identifying information. An independent t-test was used for comparisons between the Department of Dental Hygiene and other healthcare departments. Results: Regarding class-related activities, dental hygiene students were passive in presentations, discussions, and projects and had significantly lower grades in cooperative learning and challenging learning. Regarding extra-class activities, dental hygiene students had significantly lower global learning and external experiences, domestic experiences, club activities, and interactions with professors. Regarding learning outcomes, students had significantly lower grades in writing, speaking, critical and analytical thinking, data evaluation, understanding of data meaning, problem-solving ability, goal setting and execution, core content extraction, human and material resource utilization, creative convergence thinking, statistical understanding and analysis, information technology use, collaboration, sense of community, stress management, time management, and foreign language proficiency. Conclusions: Dental hygiene education requires innovation in educational methods and efforts of instructors to improve poor learning activities and outcomes.
Few dental procedures are potentially life-threatening. Note, however, that a dental extraction can result in preventable death. Severe post-extraction bleeding can occur, which may give rise to an alarming situation if there is any delay in detecting and managing the problem. The most immediate danger for a healthy patient with severe post-extraction hemorrhage is airway compromise. Acute airway obstruction from post-extraction hematoma is relatively uncommon, but it may occur with fatal consequences if there is any reluctance to maintain the airway clearance. Therefore, dentists and oral and maxillofacial surgeons should have clear understanding of the problem and measures to control it. Active bleeding that is not controlled by local measures in a dental office should be referred to the nearest hospital emergency department as soon as possible for appropriate management.
