Background: Self-leadership, an action strategy that can maximize individual capabilities, can affect the organizational commitment of dental hygienists and ultimately improve the quality of medical services. This study aims to demonstrate the need for self-leadership and organizational commitment for dental hygienists and develop measures to improve the quality of medical services. Methods: An online survey of dental hygienists working at dental hospitals and clinics in Seoul and Gyeonggi province, Republic of Korea was conducted from March 28 to May 1, 2022. A total of 341 questionnaires were returned and analyzed. The measurement tools were modified and supplemented based on the theories and models developed by Manz for self-leadership, Mowday for organizational commitment, and Cronin and Taylor for medical services. Descriptive statistics, independent t-tests, ANOVA, simple regression, and multiple regression analyses were performed using SPSS 25.0. Results: In leadership education, self-leadership is based on participation experience, the number of participants, and when and where it is received. Organizational commitment comes from participation experience, and the quality of medical services has been found to affect participation experience and location. Self-leadership had an effect on the quality of medical services (β=0.497, t=10.551, p<0.001; β=0.599, t=13.783, p<0.001; β=0.353, t=7.601, p<0.001) and organizational commitment was found to have a mediating effect. Conclusion: Dental hygienists' self-leadership has a positive effect on the quality of medical services through the formation of appropriate interrelationships within the organization. Therefore, self-leadership programs should be developed, participated in, and promoted to improve the self-leadership of dental hygienists. Moreover, hospitals should improve their environment to provide and improve self-leadership education.

이 연구는 치위생학과 대학원에 진학한 치과위생사들이 대학원 선택 후에 자신의 대학원 대학원 선택 확신에 미치는 영향을 조사하고자 하였으며 다음과 같은 결론을 얻었다. 일반적 특성과 대학원 선택동기인 외적요인과 내적요인 차이를 분석한 결과 결혼여부에 따른 대학원 특성 지각요인 중 재정접근성요인은 기혼이 높게 나타났으며, 교육프로그램요인에서는 미혼이 높게 나타났다. 월 평균 소득은 재정 접근성요인, 교육프로그램요인 평균 점수를 높게 인식하는 것으로 나타났다. 또한 경력이 낮을수록 교육프로그램요인 평균 점수가 높은 것으로 나타났다. 내적요인은 통계적으로 유의한 결과를 나타내지 못하였다. 일반적 특성과 대학원 선택 확신요인 차이를 검증한 결과 미혼일수록 대학원 선택 확신요인 점수가 높았고, 월 평균 소득에 따른 대학원 선택 확신요인과 차이가 있는 것으로 나타났다. 대학원 선택동기 외적요인 중 교육프로그램요인과 장래성요인은 대학원 선택 확신요인에 영향을 미치는 것으로 나타났지만 내적요인은 영향을 미치지 않는 것으로 나타났다. 이상의 결과를 종합해 보았을 때, 치과위생사가 치위생학과 대학원에 진학하고 대학원 확신 선택요인에 가장 중요한 요인은 교육프로그램(교수 명성과 질, 전공프로그램의 질, 교수 학생 관계, 교수학생 비율, 학술활동)요인임을 알 수 있었으며, 장래성(학위 취득 후 진로선택 유리, 소득과 수입에서 유리, 사회 진출, 박사과정 개설) 또한 대학원 선택 확신요인에 필요한 요인이라고 볼 수 있었다. 따라서 치위생학과 대학원은 치위생학과에 진학하고자 하는 치과위생사에게 교육 프로그램의 관련 정보를 제공해야하며, 학문의 발전과 전문가의 영역을 넓힐 수 있는 교육 프로그램을 개발 및 개선시켜야 할 것이다. 또한 이 연구의 결과를 활용하여 치과위생사의 인적자원을 양성함에 있어 치위생학과 대학원에서 이들에 대한 지원 방안을 마련할 수 있을 것이다.

When performing the inferior alveolar nerve block anesthesia, surgeon often faced a difficulty of the surgical operation due to the incomplete anesthesia. One of the reason is the variety of mandibular canal anatomy. Up to now, there are some reports of index cases about bifid mandibular canal among mandibular canal anatomic variation, and some classification is applied according to anatomical location and configuration. When surgical operation is performed involving mandible such as dantal implant treatment, extraction of an impacted third molar, sagittal split ramus osteotomy, etc, the position of mandibular canal should be considered. Bifid mandibular canal clinically causes troublesome cases of anesthesia when inferior alvelor nerve block, especially is performed extraction of an impacted third molar. Therefore, It is important for clinicians to recognize the presence of bifid canals on radiographys. Nowadays, the position of mandibular canal can be measured precisely by using Dental CT. It is not found by panorama image but is found by Dental CT sometimes. Among the patients, which take panorama and Dental CT simultaneously, for tooth extraction of lower impacted third molar in our department, we report the case that did not identifying in panorama but identifying it in Dental CT.

PURPOSE. This in vitro study investigates the effect of different post-rinsing times and methods on the trueness and precision of denture base resin manufactured through stereolithography. MATERIALS AND METHODS. Ninety clear photopolymer resin specimens were fabricated and divided into nine groups (n = 10) based on rinsing times and methods. All specimens were rinsed with 99% isopropanol alcohol for 5, 10, and 15 min using three methods-automated, ultrasonic cleaning, and hand washing. The specimens were polymerized for 30 min at 40℃. For trueness, the scanned intaglio surface of each SLA denture base was superimposed on the original standard tessellation language (STL) file using best-fit alignment (n = 10). For precision, the scanned intaglio surface of the STL file in each specimen group was superimposed across each specimen (n = 45). The root mean square error (RMSE) was measured, and the data were analyzed statistically through one-way ANOVA and Tukey test (α < .05). RESULTS. The 10-min automated group exhibited the lowest RMSE. For trueness, this was significantly different from specimens in the 5-min hand-washed group (P < .05). For precision, this was significantly different from those of other groups (P < .05), except for the 15-min automated and 15-min ultrasonic groups. The color map results indicated that the 10-min automated method exhibited the most uniform distribution of the intaglio surface adaptation. CONCLUSION. The optimal postprocessing rinsing times and methods for achieving clear photopolymer resin were found to be the automated method with rinsing times of 10 and 15 min, and the ultrasonic method with a rinsing time of 15 min.
