The purpose of this study was to investigate current status of sedation training for the residents in pediatric dentistry training institutions and opinions about continuing education after the residency program. Surveys were sent to 18 pediatric dentistry training institutions by e-mail, and the responses were collected and analyzed. Most of the sedation education period for the residents were the 1st-year education (61.1%) and 1 - 3 years of integrated education (55.6%). In terms of an externship, 5 institutions (27.8%) sent their residents to the department of anesthesiology. Second half of the 1st year (50%) was the highest for a resident to use sedation for the first time. The period of supervisor participation varied from not participating at all to whole time throughout the residency program. The sedation training is conducted at all training institutions, but there were variations in the experience that a resident can gain. All training institutions agreed on the necessity of continuing education of the sedation, but there were various opinions regarding time, method, and the period of review course. Overall, this study suggested that continuing education should be consisted of 1 - 2 hours of didactic education every year and clinical skills and simulation training in every 2 - 3 years.

The purpose of this study was to compare the personality types between pediatric and other dental residents. 77 pediatric dental residents and 71 other dental residents in Korea were surveyed by Myers-Briggs Type Indicator questionnaire. Myers-Briggs Type Indicator (MBTI) had 4 personality dichotomies consisting of 2 opposite characteristics that were extraversion / introversion, sensing / intuition, thinking / feeling, and judging / perception. Combinations of these four dichotomies could make 16 personality types. The percentage of pediatric dental residents was higher in sensing and judging, but there were no statistically differences. The majority of personal type was ISTJ in both groups. Statistical significance observed only in gender. The ratio of thinking was higher in male than in female (p < 0.05). The meaning of this study was the first survey performed on the personality types between pediatric dental residents and other dental residents in Korea. Further study with pre-survey orientation and increased sample size should proceed.

The purpose of this study was to develop prototype of virtual reality(VR) simulation with malocclusion models and evaluate its applicability. Task abilities, task completion time, and a satisfaction survey were compared between dentist trainees and dental students. Participants were instructed to observe virtual malocclusion models and then performed three tasks to diagnose the type of malocclusion, determine clinical findings and develop treatment plans. Their satisfaction with the simulation experience were evaluated using a questionnaire containing five questions. Task abilities of trainees related to clinical features and treatment plans were significantly higher than that of students(p < 0.01). In both groups, the task completion time for the second case was significantly reduced compared to that for the first case(p < 0.01). The satisfaction survey showed high scores and positive responses for this simulation in both groups. If the prototype of VR simulation is continuously advanced, it will be applicable for orthodontic education in pediatric dentistry.

In this study, the recognition of child abuse and neglect (CAN) and reporting attitudes of general dentists and pediatric dentists in Korea were estimated. A survey was conducted among dentists working at clinics or university hospitals, including interns and residents at dental hospital training institutions. The questionnaire, consisting of 32 questions and detailed questions, subdivided into 'general characteristics of respondents', 'CAN', 'CAN report', 'laws to CAN', 'countermeasures against CAN'. The survey was conducted using a messenger, and 176 respondents' answers were analyzed. The recognition of CAN showed high scores in the order of physical abuse, neglect, and emotional abuse. The positive attitude toward reporting CAN had a higher score than the negative attitude. Of the total respondents, 19 said they reported child abuse, and 18 said they were suspected of child abuse but hesitated to report it. Among the laws related to CAN, the protection measures for CAN reporters and the protocol for CAN showed low awareness. Since then, they have wanted to know how to find abused children and how to deal with them in education. This study is expected to be used as data to improve dentists' awareness and consciousness of CAN in the future.

The aim of this study was to evaluate the use of easily accessible machine learning application to identify mesiodens, and to compare the ability to identify mesiodens between trained model and human. A total of 1604 panoramic images (805 images with mesiodens, 799 images without mesiodens) of patients aged 5 - 7 years were used for this study. The model used for machine learning was Google's teachable machine. Data set 1 was used to train model and to verify the model. Data set 2 was used to compare the ability between the learning model and human group. As a result of data set 1, the average accuracy of the model was 0.82. After testing data set 2, the accuracy of the model was 0.78. From the resident group and the student group, the accuracy was 0.82, 0.69. This study developed a model for identifying mesiodens using panoramic radiographs of children in primary and early mixed dentition. The classification accuracy of the model was lower than that of the resident group. However, the classification accuracy (0.78) was higher than that of dental students (0.69), so it could be used to assist the diagnosis of mesiodens for non-expert students or general dentists.

This study aimed to investigate parents' and dentists' perceptions of the national oral health screening for infants and children (OHS), and evaluate the dentists' accuracy of analyzing the results of OHS. A questionnaire survey was conducted, face-to-face or online, for 90 parents of children who received OHS in the Department of Pediatric Dentistry at Yonsei University Dental Hospital and 100 dentists working at local clinic or university dental hospital from May to October 2021. Most parents and dentists were aware of the importance of OHS, and approximately 96.7% of parents were satisfied with OHS. The requirements of parents and dentists about OHS were different. The reasons for having difficulties in explaining parents after OHS and the opinions on appropriate period and number of OHS were disagreed between pediatric dentists and general dentists. Regardless of dentists' major, work experience, elapsed period after taking online education program, the accuracy of the examination result was low. In this study, various opinions of parents and dentists on OHS were collected. Efforts should be made to enhance the oral health of infants and children by considering the requirements of parents and dentists and improving the accuracy of examination results.

Thermoformed appliance, which has been recently introduced for dental usage, is an appliance made of thermoformed sheets and formed with positive or negative pressure under heat. Thermoplastic material is a kind of plastics and can be repeatedly softened by heat. It is classified into hard elastic foil, hard/soft compound foil and soft elastic foil, including BIOPLAST, BIOCRYL, IMPRELON, etc. It has been developed in 1969 and is available in various thickness, shape and color. There are two types of Vacuum former for thermoplastic materials; the pressure type and suction type. The former is much better than the latter for fabrication of various appliances due to its higher pressure. The authors have applied these appliances to some cases - chin cap, active retainer, individual Fluoride tray, mouth protector, bracket transfer mask, bruxism splint(night guard), Essix appliance - by pressure type Vacuum former($Biostar^{(R)}$). The thermoplastic appliances have numerous advantages such as simple procedure, short working time, clean and transparent product, less objectionable taste. But its outstanding advantage would be its excellent biocompatibility bacause it has no monomer and hence no tissue irritation. Although there is some limitations in its usage, it can be used widely for various purposes especaily for pediatric dentistry.

For prevention of ECC, the Korean Academy Of Pediatric Dentistry(KAPD) advocate that Children should be seen as early as 6 months of age after the first tooth erupts, or 12 months of age. Pediatrics have increased access to new mothers and children 6 to 12 months while dentists does not see young children unless there are urgent problems. Therefore, they have an opportunity to impact infant oral health care. This study's purpose was to examine pediatricians' awareness and experience about infant oral health care. For the study, we surveyed of 150 pediatricians in korea. The survey comprised 10 questions related to infant oral health care and the recommended age a child go for their first dental visit. The results were as follows: 1. Most respondents had been referred children to a dentist for treating ECC and more than half of respondents reported that they did not do oral examination in their practice. 2. The majority of surveyed pediatricians are not advising patients to see the dentist by 1 year of age. 3. The surveyed pediatrician's awareness of infant oral health care is insufficient. The oral health education should be reinforced. 4. There is a need for increased infant oral health care education in the medical and dental communities.

The purpose of this study was to evaluate the applicability of virtual reality simulation after experience of dental caries diagnosis for dental students before exposing to clinical pediatric practice. A pediatric patient model of a five-year-old child with primary dentition was developed and a caries model that is amenable to VR(virtual reality) diagnosis was organized and set-up. The dental student's were allowed to use the simulated model for fifteen minutes and their experiences were evaluated using a self-reported questionnaire to evaluate presence and usability of this application. Overall, virtual presence and appearance area of the simulation were highly scored. The result indicates that the VR model has no significant difference from the actual clinical caries regardless of grade of students, gender and VR experience. If the prototype is continuously advanced, its applicability in dental education will increase.
