This study will be used as basic data to hold clinical training effective by researching and analyzing frequency, satisfaction and stress for the clinical practice of dental hygiene course students. The survey was undergone from Feb. 1, 2014 to Mar. 31 for 219 dental hygiene course juniors who had experienced clinical training in 3 year colleges located in Daejeon and Chungcheong Province. From the study, general and university hospital holds the highest satisfaction in clinical practice and dental offices in acquiring skills. Also, a significant difference is shown between the frequency and satisfaction according to clinical training sheets. The highest degree of stress is shown in dental offices for 'toothbrushing training and dental health education' and in general and university hospital for 'patient counselling'. Therefore, consideration should be made to establish the direction of education, standard criteria and evaluation method for student clinical training to raise its effectiveness.

The aim of this study is to evaluate the development of the left mandibular third-molar development with modified Demirjian method and its relation to chronological age. A total of 1653 digital panoramic radiographs of healthy individuals aged between 7 and 23 years who visited Yonsei University Dental hospital were selected. The developmental status of the left mandibular third molars was assessed using dental maturity scoring proposed by Demirjian et al. The mean age of the first appearance of mineralization, complete crown formation, and complete root formation were around 9, 14, 21 years respectively. Statistically significant differences between males and females in the development stage of D and G were revealed that crown formation and root length completion were attained earlier in males than in females. There was significant positive relationship between age and third molar development in both sexes, and new formula was presented to estimate age of children and adolescents based on their developmental stages of third molars. In this study, the use of left mandibular third molar as a developmental marker is appropriate, and age estimation can be attained with dental maturity stage.

Hemophilia is a congenital hemorrhagic disease in which blood clotting is impaired and hemostatic abnormalities occur when even one of the 13 factors required for blood clotting are deficient. Among the 13 factors, hemophilia A (factor 8), hemophilia B (factor 9), and hemophilia C (factor 10), depending on the deficient coagulation factor. A male patient in his 40s diagnosed with hemophilia A visited the dentist at Eulji University Hospital for problems with alveolar bone absorption and periodontal abscess caused by overall chronic tooth inflammation, and showed overall bone absorption and inflammation at the time of initial diagnosis. No complications or bleeding tendency were observed in the rest of the area except for #35 and #36 due to regular visits for 10 years, overall good oral conditions, and no side effects or complications were observed.

In cases of a patient referral, the general dentist should communicate the patient's dental information as clearly as possible to the specialist to whom he/she is referring his/her patient. For this reason, it is necessary to write a referral letter in an accurate and complete manner. The purpose of this study is to analyze the referral letters of patients who are referred to the department of conservative dentistry in a dental university hospital. From January, 2017 to December, 2018, we gathered the information of the patients who were referred to the department of conservative dentistry in a dental university hospital with referral letter. We evaluated the fidelity of a total of 750 referral letters and recorded the information of the referral dentist and the dental clinic. The relationship between each item and fidelity was analyzed using SPSS 18.0 program. The analysis of the contents of the referral letters yielded the following results: The fidelity of the referral letter was higher when the patient was referred during the root canal treatment, or when there was a root canal filling or when there was pain during chewing. The fidelity of referral letter was low in cases where the referring clinic is close to and has cooperative relationship with dental university hospital. Among the factors affecting the fidelity, the year of graduation of the referral dentist was the most influential. This study confirmed the fact that the clinical practice of writing patient referral letters still leaves much to be desired. In order to solve this problem, it is necessary to create more clear and standardized guidelines for writing referral letters.

At the department of prosthodontics, the elderly patients with severely atrophied alveolar ridge who have been wearing complete dentures for a long period frequently visit the clinic. In general, the open-mouth impression technique for manufacturing a mandibular complete denture to secure primary support on buccal shelf area has been prevalent. In addition, for securing retention and stability of mandibular denture, we should consider diagnosis, oral function, denture border, occlusal plane, teeth arrangement, and patient training, etc.. But in edentulous patients with severe alveolar bone atrophy, it may hardly secure retention and stability of mandibular complete denture. To promote these, some of clinicians are making an attempt manufacturing the mandibular complete dentures using closed-mouth impression technique based on several reports that compare various impression techniques including open-mouth and closed-mouth impression technique. This case report suggests closed-mouth impression technique may promote retention and stability of mandibular complete denture and compares between the two impression techniques clinically.

This study was conducted to develop a plan for emotional labor of clinical dental hygienists by understanding the factors affecting their emotional labor. Self-administered questionnaires were distributed to 293 dental hygienists who worked in dental hospitals and clinics located in Busan and Gyeongsangnam-do from June to September in 2013. The questionnaire items used in this study consisted of 5 items of general characteristics, 2 items of characteristics related to turnover, and 9 items of emotional labor. t-test, ANOVA, and multiple regression analysis were performed using the SPSS Statistics ver. 17.0 for Windows program for data analysis. The average level of the study subjects was $69.85{\pm}12.82$. With regard to the emotional labor according to the general characteristics, the frequency of emotional expressions (p<0.037) showed significant differences in the marital status. The workplace showed significant differences in the frequency of emotional expressions (p<0.001), attentiveness of emotional expressions (p<0.002), emotional dissonance (p<0.032), and total (p<0.001). The turnover intentions showed significant differences in the frequency of emotional expressions (p<0.001), attentiveness of emotional expressions (p<0.001), emotional dissonance (p<0.001), and total (p<0.001). As a factor affecting emotional labor, turnover intention (p<0.001) and workplace (p<0.001) had an effect on emotional labor. The results showed that turnover intention and workplace were associated with the emotional labor of dental hygienists. There is a need to develop an emotional education program to make it possible to effectively manage emotional labor of dental hygienists for providing high-quality medical services of dental institutions.

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.

Due to increasing demand for aesthetics, zirconia crowns have become a popular choice for treating primary molars. However, there is limited literature available comparing the survival rates of zirconia crowns with those of other restorative materials. The objective of this study was to compare the 36-month survival rates of zirconia crowns and stainless steel crowns for proximal caries, as well as to analyze failure types associated with each crown type. Electronic medical records and radiographs of 1,061 primary molars from 498 patients treated with 2 types of prefabricated crowns at Chosun University Dental Hospital and 2 private dental clinics between 2017 and 2019 were collected and analyzed. The survival rate of zirconia crowns was found to be lower compared to that of stainless steel crowns. Regarding the groups without pulp treatment, the survival rate of stainless steel crowns was significantly higher than that of zirconia crowns. However, in the groups that received pulp therapy, no significant difference in the survival rates was observed between the two preformed crowns. Notably, abnormal root resorption or periapical lesions were identified as the primary cause of restorative failure in stainless steel crowns, whereas loss of restoration was the predominant cause in zirconia crowns. This study holds valuable implications for clinicians when selecting preformed crowns for primary molars.
