This study aims to apply the Generalizability Theory (G-theory) for estimation of reliability of evaluation scores between raters on Patient Dentist Interaction. Selecting a number of raters as multiple error sources, this study was analyzed the error sources caused by relative magnitude of error variances of interaction between the factors and proceeded with D-study based on the results of G-study for optimal determination of measurement condition. The estimated outcomes of variance component for accuracy among the Patient Dentist Interaction evaluation with G-theory showed that impact of error was the biggest influence factor in students. The second influence was the item effect, and the rater effect was relatively small. The Generalizability coefficients for case1 and case2 which were estimated through the D- study were calculated relatively low.

Each college of dentistry in Korea is examining and reorganizing its own curriculum to prepare students for the practical examination of the National Dental Licensing Examination. Conducting an assessment of students' competency of communication skills with standardized patients is the first attempt for the examination. Yonsei University College of Dentistry carried out the evaluation of communication attitude, communication written exam, and communication skills practice with standardized patients for Third year predoctoral students. The purpose of this study is a) to find out the relationship between the variables measured in communication skills education and b) to make a new basis for the application of communication education and evaluation in dentistry. Based on the results of the study, the following suggestions for the operation of a dental communication curriculum can be drawn: First, the communication classes and the practice with standardized patients should be based on the wide support of the school. In addition, the patient-dentist interaction (PDI) should be practiced in the same way as practically possible by predoctoral students. Moreover, a space is required to allow predoctoral students to practice PDI. Second, the communication score given by the standardized patients was the most influential on the total score of PDI. This indicates that the communication practice with the standardized patients for the practical examination of the National Dental Licensing Examination is a meaningful process in the course of its communication education.

Purpose: The practical examination portion of the National Dental Licensing Examination (NDLE) is slated to be administered in the latter half of 2021 in the form of a clinical performance examination that comprehensively evaluates the patient-dentist interaction using standardized patients (SPs). The SPs should be equipped with the basic qualities and capacity as evaluators for a fair and reliable administration of the test. Materials and Methods: In this study, we analyzed the existing training materials for SPs who participated in domestic and overseas practical tests for the development of training materials for SPs through seminars and surveys of 11 dentistry schools and colleges. Result: First, SPs should be selected according to the basic quality criteria and capacity, which they must possess, and the preliminary basic training about the details which they must have knowledge of and be provided through videorecorded cases before the implementation of the preliminary field training. Second, the roles of SPs and the calibration process of the evaluation result forms are needed when conducting the preliminary field training for SPs. After watching video-recorded scenario cases, the SPs participate in discussions about the watched videos before proceeding to calibration practices of evaluation result forms. Third, because the Type A questionnaire of the practical examination of the NDLE is dependent on the SPs' capacity and training, the fairness of the practical test is largely dependent on the SPs. Therefore, practicing the roles as evaluators and evaluation training should be provided using practical test items that can improve the reliability of the test and show a high level of reproducibility about the same case. Conclusion: The findings of this study will be utilized for the development of training materials for SPs, so they can participate in the administration of a fair and reliable practical examination of the NDLE.

The introduction of smart technology provides accuracy, safety, and efficiency to both physicians and patients. Although interest in a clear aligner is increasing among users worldwide, the current clear aligner requires a visit to the hospital every one or two weeks for replacement, which is a very cumbersome process. There is also confusion among dentists and patients because about 40 to 80 devices are made, and calibration is done based on the order and duration of the clear aligner. Therefore, this study designed and developed a clear aligner management system so that communication between the patient and dentist can be smoothly performed by inserting the QR code into the transparent correction device. As a result, the size of the QR code was recognized as $6{\ast}6mm^2$ which can be used in the oral and the recognition distance was 100% within 12 cm. Since the dentist can remotely manage the patient with the proposed system and improve the correction effect, it is possible to manage patients abroad, as well as domestically.

The autism is a complex disorder, characterized language impairment, perceptual-motor difficulties, and social disturbance. The autistic children have hyperactivity, lack of communication' lack of cooperation, inappropriate patient/dentist interaction, so they require professionally recognized behavioral management technique during dental treatment such as behavior modification, phamacological agents, and general anesthesia. A behavior management technique can be chosen by factors such as the severity of autism and possible accompanying disabilities, degree of cooperation, oral and general conditions of children. A non-pharmacological behavior modification may be selected for the autistic children who are able to communicate with dentist with mild dental caries, without compromised medical history. In case of excessively hyperactive, destructive, antisocial, and/or severe communicative disorder, a sedation technic with chloral hydrate, hydroxyzine, midazolam or nitrous oxide gas might to be performed. General anesthesia is preferred for severe communicative and/or behavioral disorder, elder age, excessive dental care need, and living a remote area.

Prosthetic decision-making is complex because of various factors, and involves a combination of the individual dentist's interpretation of the objective clinical data and his or her interaction with the patient. Increasing therapeutic options and emerging outcome data demand the constant re-evaluation of our decision-making process. In this case, fixed prosthetic restorations were selected as a treatment method to reconstruct the occlusal plane of a patient with disharmonious occlusal plane. And the occlusal plane was re-established by establishing a treatment plan through diagnostic wax-up. Provisional restorations obtained by continuous re-evaluation for a sufficient period of time was replicated to definitive restorations using CAD/CAM technology. The results were satisfactory when they were observed through clinical follow-up for 3 months after the end of treatment.
