Objective: The purpose of this study was to evaluate the accuracy of the inter-arch relationship of digital models generated using two types of intraoral scanners. Methods: In total, 34 plaster model samples were used. Two corresponding digital models were created using two types of intraoral scanners. A total of 15 variables were measured. The plaster model was directly measured using a digital caliper, while the digital models were measured using a software. The accuracy of the measurements was evaluated using repeated measures analysis of variance and the Friedman test. Results: Among the 15 measurements, 6 measurements[Overjet, Overbite, DZ_11-41 (Distance between the gingival zenith of maxillary right central incisor and mandibular right central incisor), DZ_16-46 (Distance between the gingival zenith of maxillary right first molar and mandibular right first molar), DZ_13-33 (Distance between the gingival zenith of maxillary right canine and mandibular left canine), and DZ_23-43 (Distance between the gingival zenith of maxillary left canine and mandibular right canine)]showed statistically significant differences, with DZ_23-43 showing the largest difference of 0.18 mm. The other measurements showed no statistically significant differences. Conclusions: Regardless of the type of scanner used for preparation, digital models can be used as clinically acceptable alternatives to conventional plaster models.
The infraocclusion is defined as a condition, in which teeth are present with their occlusal surface below the neighboring teeth, and long after, they reach occlusion. The most common cause of infra-occlusion is thought to be ankylosis. The treatment options for patient with infraocclusion of primary molars are observation, restoration and surgical removal of the affected teeth. We report a case of 8 – year – old boy who visited our clinic for consultation of orthodontic treatment. The patient was diagnosed by multiple infraoccluded primary molars with permanent successors. Surgical extraction were performed on primary molars. After follow-up of 7 months period, #44, 45 were erupted and the degree of posterior open bite was decreased.
This study examines the ethical situations of the dental profession of Korea and the current state of dental ethics education in dental colleges of U.S. to identify the necessity of professionalism and expert ethics. We propose the ‘Making Good Dental Clinic Checklist’ for improving ethical awareness and behavior, designed by the Good Dental Clinic Group of Dental Service International. This is based on our clinical experiences and our experience of translating Dental Ethics at Chairside into Korean.
Although museums of dentistry and dental museums are both museums related to dentistry, they may differ significantly in the scope and the content regarding the audiences. Museums of dentistry, which display a variety of dental instruments, materials, and photographs, help you learn about the development of dentistry and primarily attract a lot of attention from those who work in dental fields. These museums, however, don't get much attention from the general public. The dental museum, which displays everything related to teeth and dental care, can attract a lot of curiosity and attention not only by those in dental fields, but also by the general public. Dental museums should purpose public health education; they should not just be a place for looking around. This is because the experience of the dental museum has the power to engage people. Therefore, if you add educational functions to the dental museum and make it a place to learn about dental history and oral health care, it can be the institution where culture and health are combined. We need to study history to better understand which improvements we have made and also to see what we need to aim for in the future. The purpose of this study is to examine the actual way each of 28 dental museums in 7 different countries is operated by describing what I saw when I visited them. In addition, the current state of museums of dentistry in Korea is examined and the future development directions is also considered.
Until recently, dentistry did not show notable social conflicts with other medical professionals. This means that conflicts did not surface as medical doctors took the dominant position even though areas of intervention have been overlapped. The recent conflict between medical professionals, which began with clashes in the area of oral and maxillofacial surgery, have been embodied in the Supreme Court ruling on the use of Botox by dentists and the court ruling on the use of oral devices in oriental medicine. We look discuss at each case in detail to seek a solution to the problem of interprofessional conflict. We present professional duty of self-development and interprofessional education as a way to resolve disputes between medical professionals, which would be a major problem in the future of dentistry and medicine.
