The dental care delivery system and the dental specialty system have a very close relationship each other. Compared to Korea. Western European countries with predominant public sector in dental service have recognized merely 2 or 3 dental specialties, while North American countries with predominant private sector, 8 or 9 ones. It is desirable to adopt the dental specialty system as soon as possible in Korea to encourage scientific development in various dental specialties and qualitative advance in dental service. We, however, have to establish equitable dental care delivery system which can use limited dental resources efficiently as follows. 1. clarifying the different roles in assignments between general dentists and specialists by the amendment of the related laws such as the Medical Act and establishing the organic patient-referral system. 2. adopting the dental specialty system and expanding personnel and equipments so that the dental college hospitals, especially dental divisions of general hospitals, night function as secondary care facilities with specialties. 3. determining the size of dental specialists according to the national needs for dental specialized service's, whose number is to be not more than 10% of the total dentists. 4. transferring the function of accredating dental specialists to the efficient, self-controlled professional organization such as the Korean Dental Association rather than putting it under the governmental control. 5. conducting a comprehensive review of specialty education and practice for re-recognition, and maintaining competence of specialists by re-accredating them periodically. I expect this article to contribute to further discussion about the dental specialty system in Korea in productive and practical way. I am sure that we can Establish this system in the near future when people in every walks of life-the academic circle, the press, the authority concerned, consumer groups and the Korean Dental Association-take part in the discussion with special concern.

The aim of this study was to evaluate the dental specialty system from the viewpoint of korean constitution. An attempt to introduce a dental specialty system has been repeated many times, but it was interrupted by the dispute of the interested parties, especially general practice dentists, trained dentists and the authorites concerned. The korean constitutional court decided on July 16th 1998 that the lack of the examination to be a dental specialist was against the korean constitutional law and the authority concerned should prepare the legal procedure for the dental specialist examination in proper time. Though the dental specialty system may be discussed in a variety of view, it should be established on the ground of the korean constitutionalism. According to the korean constitution, all the people can develop their abilities at the maximum and have their dignity, preciousness and right to seek their happiness. With the view of spirits of the constitution, dental specialty system should be more open widely to those who want to be a specialist. It should be also allowed to the dental specialists that they reveal their specialty and creativity. However, the representatives of the korean dental association(KDA) decided at the 50th annual meeting that the dental specialists should not reveal or annonce their specialties at the first step of the dental care and all the present dentists give up to be specialists. As conclusion of this study the proposals of the KDA seems to be against the korean constitution and hardly fulfills the needs of the times.

Even though Korean Dentistry practically have adapted the specialty system, the execution of regulation was tentatively delayed during the past 30 years. Recently a group of dentists advocated that the legislation must be executed. The Korean Dental Association announced the new legislation for specialty program to accommodate the desires of almost of dentists. It is prospected to restrict the specialist as low as 8% or up to 15%. But in fact, during the past 10 year, the applicant to the specialty program increased rapidly and about 40% of graduate are in the specialty programs these days.(omitted)

This research is an attempt to establish a basic material in discovering the subjective types of the dental coordinators occupational consciousness, utilizing the Q-Method Theory, which is capable of measuring the subjective nature of human being by scientific and systematic method. The characteristics of each type were analyzed so as to have the dental coordinator to possess the desirable understanding of the occupational view together for them to have self-confidence as a lifetime specialty occupation. Upon completion of the study, it was found that there are three types of subjective views pertaining to the occupational consciousness on the dental coordinator. The result on the analysis of the characteristics is as follows : Type 1 is the Taking Serious View on the Patient Service, which priority is placed on kindness and looking after any difficulties of the patient, namely, it is the type that puts the importance on the high level medical examination and treatment based on good service. Because of the kind service to the patient, those under this category considered their job satisfaction have been improved. It goes without saying that they were developing the services, which satisfy themselves, and it was confirmed that they thought that they should make things smooth for any development of problems that may arise between the patient and the dentist. Type 2 is the Taking Serious View on Career and Organizational Strength. This is a type that aims on the systematic nature of the internal job, namely, organizational strength itself viewed from the stand point thai either self-confident or work merit is proportional to experience. This type is to actively treat the problem and endeavor to solve the issue when dissatisfaction is held by the dental hospital system, which is either followed according to the work responsibility or by an organization having an appropriate system on remuneration, Type 3 is the Placing of Importance on the Overall Circumstances. This is the type that places importance on the overall now of the dental hospital, and it is the type, that most greatly recognizes the importance of the role of the dental coordinator. The dental coordinator should provide the sense of reliability to both the dentist and to the staff of the medical examination and treatment and should be able to adjust smoothly the overall now of the medical treatment. The dental coordinator is expected to be a medical service specialist, who is capable to solve the problems of the staff of the medical treatment intuitively and to adjust the relation between the employees. With the above result, it was found that although there was no mutual exclusiveness between the respective types, there are particular characteristics among each type. Therefore, this research has discovered and analyzed the subjective view types relative to the occupational consciousness of the dental coordinator for the proper understanding on the characteristics of each type to enable the dental sanitary students and the graduates of the Dental Sanitary Department, who are aspiring to become dental coordinator, as the basic guide material to be actively utilized.

Objectives: The present study was conducted to determine the reproducibility of peri-implant tissue assessment using the new implant success index (ISI) in comparison with the Misch classification. Materials and Methods: In this descriptive study, 22 cases of peri-implant soft tissue with different conditions were selected, and color slides were prepared from them. The slides were shown to periodontists, maxillofacial surgeons, prosthodontists and general dentists, and these professionals were asked to score the images according to the Misch classification and ISI. The intra- and inter-observer reproducibility scores of the viewers were assessed and reported using kappa and weighted kappa (WK) tests. Results: Inter-observer reproducibility of the ISI technique between the prosthodontists-periodontists (WK=0.85), prosthodontists-maxillofacial surgeons (WK=0.86) and periodontists-maxillofacial surgeons (WK=0.9) was better than that between general dentists and other specialists. In the two groups of general dentists and maxillofacial surgeons, ISI was more reproducible than the Misch classification system (WK=0.99 versus WK non-calculable, WK=1 and WK=0.86). The intra-observer reproducibility of both methods was equally excellent among periodontists (WK=1). For prosthodontists, the WK was not calculable via any of the methods. Conclusion: The intra-observer reproducibility of both the ISI and Misch classification techniques depends on the specialty and expertise of the clinician. Although ISI has more classes, it also has higher reproducibility than simpler classifications due to its ability to provide more detail.

In general, to conduct aesthetic restorations, various analyses are carried out using a camera from the initial examination with the final prosthesis in consideration. With the reality that many dentists are using digital cameras, it can be considered that the time of digital impression has already started. Just as the recent general trend is that more and more internationally renowned photographers are switching their film cameras to digital counterparts, it is likely that CAD/CAM will show another direction in the area of the aesthetic dentistry that we may want to pursue. With the word 'digital', the convenience and economics often come to mind in the first place. However, from the dental clinical viewpoint, it is important to improve and develop the CAD/CAM system based on understanding its specialty and superiority while respecting the conventional analog techniques. However, a regretful aspect is that it is often difficult to catch up with the latest advancements for proper referencing and follow-up of digital technologies since the CAD/CAM device and material are developing very rapidly. Accordingly, although it is ideal to have hands-on experiences in various digital material and devices, and adapt to their fast changes, it must be stressed that the clinical application is to be implemented on the basis of the proven traditional way of dental clinics in order to obtain better outcomes. This presentation will explore types of approaches that can be made by combining the traditional techniques and the CAD/CAM from the aesthetic viewpoint. In addition, it is hoped and eagerly awaited that the CAD/CAM restoration may play a significant role in the field of the 'digital art'.

Purpose: For head and neck cancer patients treated with radiation therapy, proper immobilization of intra-oral structures is crucial in reproducing treatment positions and optimizing dose distribution. We produced a man-made tongue immobilization device for each patient subjected to this study. Reproducibility of treatment positions and dose distributions at air-and-tissue interface were compared using man-made tongue immobilization devices and conventional tongue-bites. Materials and Methods: Dental alginate and putty were used in producing man-made tongue immobilization devices. In order to evaluate reproducibility of treatment positions, all patients were CT-simulated, and linac-gram was repeated 5 times with each patient in the treatment position. An acrylic phantom was devised in order to evaluate safety of man-made tongue immobilization devices. Air, water, alginate and putty were placed in the phantom and dose distributions at air-and-tissue interface were calculated using Pinnacle (version 7.6c, Phillips, USA) and measured with EBT film. Two different field sizes (3$\times$3 cm and 5$\times$5 cm) were used for comparison. Results: Evaluation of linac grams showed reproducibility of a treatment position was 4 times more accurate with man-made tongue immobilization devices compared with conventional tongue bites. Patients felt more comfortable using customized tongue immobilization devices during radiation treatment. Air-and-tissue interface dose distributions calculated using Pinnacle were 7.78% and 0.56% for 3$\times$3 cm field and 5$\times$5 cm field respectively. Dose distributions measured with EBT (international specialty products, USA) film were 36.5% and 11.8% for 3$\times$3 cm field and 5$\times$5 cm field respectively. Values from EBT film were higher. Conclusion: Using man-made tongue immobilization devices made of dental alginate and putty in treatment of head and neck cancer patients showed higher reproducibility of treatment position compared with using conventional mouth pieces. Man-made immobilization devices can help optimizing air-and-tissue interface dose distributions and compensating limited accuracy of radiotherapy planning systems in calculating air-tissue interface dose distributions.
