Objectives: This research is to examine the relationship between dental hygienists' exposure to incivility from doctors, bosses, colleagues, patients, their family and visitors, and their turnover intention. Methods: The research was conducted using Nursing Incivility Scale (NIS) and a survey. The survey was conducted from September 10 to October 20, 2015. 240 dental hygienists were conveniently sampled from Forty dental clinics and offices in Seoul, Incheon, Gyeongi-do, and Chungcheog-do. Results: The dental hygienists' exposure to incivility and turnover intention showed correlation (p<0.01), and its sub-factors, - the incivility from colleagues, doctors, patients and visitors - are also correlated with their turnover intention (p<0.01). The strongest factor affecting dental hygienists' turnover intention was incivility from doctors (${\beta}=0.279$, p<0.001), followed by colleagues (${\beta}=0.168$, p=0.029), patients and visitors (${\beta}=0.148$, p=0.026). The modified explanation ability of this model is 24.9%. Conclusions: Dental hygienists' exposure to incivility in workplace is highly correlated to their turnover intention. A program to educate dental hygienists positive mental attitude, communication skill to deal with incivility, and stress reduction method is therefore required in order to reduce their turnover intention.

The coverage of the National Health Insurance for the elderly is expanding to denture and implants. Although the National Long-Term Care Insurance was just being settled, Oral health service was not provided to the Elderly in Long-Term Care Facilities. The long-term care facilities had part-time facility doctors. However, there is no dentist in the long-term care facility because of lack of long-term care insurance-related legislations. The amendments of long-term care insurance-related legislations for the introduction of part-time facility dentists are needed because the elderly in long-term care facility are vulnerable to oral health. For the substantial management of the National Long-Term Care Insurance, the development of oral health service model for the elderly and education materials for the dental team will be needed. Also, adequate dental service fee of the National longterm care insurance will be needed.

Purpose: With the development of digital dental technology, we are manufacturing prosthetic crown in various ways. However, the wax-up method that makes existing prosthetic crown is also used steadily. Thus, we will compare the shape of the crown designed with wax-up and the crown designed with CAD. Methods: Sculpt the crown with wax-up on the model to 10 dental technicians. The same model was used to design the crown CAD. Measure the size of the sculpted crown. The shapes were compared in three dimensions. Results: As a result, we could observe a difference in size and shape in crown designed with wax - up crown and crown. Conclusion: These results suggest that there are differences according to the method of carving crown and the method of processing.

3D CAD technology has been extended to a medical area including dental clinic beyond industrial design. The 2D images obtained by CT(Computerized Tomography) and MRI(Magnetic Resonance Imaging) are not intuitive, and thus the volume rendering technique, which transforms 2D data into 3D anatomic information, has been in practical use. This paper has focused on a method and its implementation for forming 3D geometric surface model from laminated CT images of the pubis. The implemented system could support a dental clinic to observe and examine the status of a patient's pubis before implant surgery. The supplement of 3D implant model would help dental surgeons settle operation plans more safely and confidently. It also would be utilized with teaching materials for a practice and training.

Recently the micropig has been developed as human disease model. The dental and orofacial region of micropig is similar to that of humans, so it has been used for testing implant materials and techniques. The purpose of this study is on dental image at each age using radiography and computed tomography. Total twenty-two male micropigs, two or three animals of each 1, 3, 5, 7, 9, 12, 18 and 24 months old, were given radiographic examinations. After general anesthesia, extra- and intra-oral radiographic technique and computed tomographic scans were performed to assess the dental characterization of micropigs. The total deciduous dental formula comprised 28 teeth and was depicted as Di 3/3, Dc 1/1, Dp 3/3. The total permanent dental formula comprised 44 teeth and was depicted as I 3/3, C 1/1, P 4/4, M 3/3. Hypodontia of the first premolars was common in the micropig. The permanent teeth erupted from 3 to 24 month after birth. The sequence of eruption of the permanent teeth was M1, P1, I3, C, M2, I1 + P3 + P4, P2, I2, M3. Dental imaging enables visualization of the unerupted teeth and gives more information about the development of the teeth. The growth pattern of the teeth obtained through radiographic and computed tomographic examination provides basic data in the micropig as animal model for dental research.

Objectives: The objective of this study was to examine the effect of mentoring function on job satisfaction, organization commitment, and turnover intention in the newly employed dental hygienists. Methods: Two hundred and fourteen dental hygienists in Daegu and Gyeongbuk completed a self-reported questionnaire from January to May 2013. The instrument for the questionnaire consisted of mentoring function, mentoring personality, job satisfaction, organizational commitment, and turnover intention. The data were analyzed by frequency analysis, ANOVA, correlation analysis, and multiple regression analysis. Results: The longer duration of the mentoring for the newly employees strengthened job satisfaction and organization commitment. The mentoring function had a positive effect on job satisfaction and organization commitment, and decreased turnover intention. The higher quality of personality overcome the turnover intention. Conclusions: The mentoring is very important to enhance the job satisfaction and organization commitment in the newly employees. Loner duration of work(${\beta}=.268$, p=0.008) explained higher job satisfaction. Higher quality of personality(${\beta}=0.279$, p<0.001) also had higher job satisfaction. The explanation power of the model was 36.5% and the revised model explanation was 35.6%. The effective mentoring is closely related to job satisfaction and organization commitment and it can reduce turnover intention.

Purpose: The purpose of this paper was to evaluate the occurrence of errors regarding adaptation by conducting a three-dimensional assessment comparing the bridge type dental restoration after the cutting process, which has multiple abutments, with a single type dental restoration. Methods: By using ten identical files obtained by scanning the master model, thirty designs were created consisting of ten maxillary right first premolars and ten maxillary right first molars with single crown abutments, along with ten bridge designs with the identical abutment. A 5-axis milling machine was used to produce the design file. The produced denture prostheses were scanned using a silicone replica for a STL file. An evaluation was conducted using 3D analysis software on the master model and each of the thirty data files. Results: The RMS value of the pre-molar (14) was $38.4{\pm}4{\mu}m$ for single and $54.7{\pm}6{\mu}m$ for bridge abutment; therefore, a statistically significant difference was observed for single and bridge designs although both shared the same abutment form (P<.05). Also, the RMS value of the molar (16) was $47.6{\pm}2{\mu}m$ and $56.6{\pm}5{\mu}m$ for the single and bridge designs, respectively, thereby presenting a statistically significant difference (P<.05). Conclusion: As a result, dental prosthesis fabricated using the single method presented better internal adaptation outcomes.

The aim of this article was to review various methods used to evaluate the accuracy of digital dental models. When evaluating the accuracy of digital models, the errors can be reduced by educating examiners and using artificial landmarks. The accuracy evaluation methods of digital dental models are divided into linear measurement, 2-dimensional cross-sectional analysis, and 3-dimensional best fit measurement. As the technology of scanners develops, many studies have been conducted to compare the accuracy of digital impression and conventional impression. According to improvement of scan technologies and development of 3-dimensional model analysis software, the ability to evaluate the accuracy of digital models is becoming more efficient. In this article, we describe the methods for evaluating the accuracy of a digital model and investigate effective accuracy analysis methods for each situation.
