Special Practitioner exists based on the need for special fields that are required to manage difficult patients with specialized skills distinguished from General practitioner. The purpose of dental specialist system is to manage patients who are not treatable by general practitioner by training doctors specializing in one specific field, thereby, enhancing health of the public. Oral Medicine deals with orofacial pain, oral soft tissue disease, forensic dentistry, oral diagnosis. In these days, living environments of city life bring about increase in stress which ultimately lead to increase in prevalence of temporomandibular disorder, oral soft tissue disease, neuropathies such as trigeminal neuralgia, and hence, the number of patients seeking help of those symptoms tend to increase. The purpose of this study was to analyze the rate of referrals and the routes of patients seeking help by investigating 3,707 patients who visited Department of Oral Medicine, College of Dentistry, Yonsei University, from August, 2004 to April, 2005. The results were as follows: 1. The types of disease referred to the Department of Oral Medicine were orofacial pain, oral soft tissue disease, forensic dentistry, oral diagnosis. 2. The rate of referrals was 58.51% which implies that more than half of the patients visiting the Department of Oral Medicine were referred. 3. The types of institution which made referrals were analyzed, and as a result, dental clinics made most of the referrals with the rate of 83.23%, while that from medical or oriental medical institutions was 16.78%. 4. Among the patients who visited the Department of Oral Medicine on their own, 30.52% gained the information about the Department of Oral Medicine from internet and mass media, and from neighbors. From the above results, most of the patients visiting the Department of Oral Medicine were found to be referred not only from the field of dentistry but also from the field of medicine. These suggest that Oral Medicine manages patients who are not treatable by general dental practitioners, and medical specialists tend to cooperate with the Department of Oral Medicine to manage diseases associated with Oral Medicine. Therefore, the role of Oral Medicine can be considered to be important as a special field, and the results of this study should be considered when working out a policy of Dental specialist system on demand and supply of residents in the future.

While the shielding substances of radiation shields in medical institutions are beginning to be replaced by environmentally friendly materials, radiation protection according to the shielding properties of environmentally friendly substances is becoming an important factor rather than the existing lead shielding properties. Tungsten and barium sulfate are representative shielding materials similar to lead, and are made in sheets or fiber form with eco-friendly materials. Ytterbium is an impermeable material used as a fluorine compound in the dental radiation field. This study aims to evaluate the shielding performance in the x-ray shielding area by comparing the shielding properties of ytterbium by energy band and that of existing eco-friendly materials. When three types of shielding sheets were fabricated and tested under the same process conditions, the shielding performance of the medical radiation area was about 5 % difference from tungsten. Furthermore, shielding performance was superior to barium sulfate. In the cross-sectional structure of the shielding sheet, there was a disadvantage that the arrangement of particles was not uniform. Ytterbium oxide showed sufficient potential as a medical radiation shielding material, and it is thought that it can improve the shielding performance by controlling the particle arrangement structure and particle size.

This study was designed to compare the perception of dental hygiene students and general public with respect to minor variations in maxillary anterior tooth size, alignment and their relation to the surrounding soft tissues. Maxillary anterior teeth were intentionally diagrammed in varying degree of deviation with respect to one of three common anterior esthetic discrepancies including variations in crown length, shape of gingival margin, and length of interproximal contact. Seventeen images were generated to be preferentially selected by 2 groups consisting of dental hygiene students and lay people in Busan(total of 216). The obtained results were as follows; 1. Both group preferred gingival margin of lateral incisor to be 0.5mm lower than that of central incisor. 2. Both group preferred the gingival margin shape of central incisor has 1/9 horizontal component of the crown width. 3. Both group preferred length of the interproximal contact has 1/2 of the crown length. The results of this study may be considered to influence the decision making process by dental professionals with respect to designing the anterior esthetic gingival line.

Ectodermal dysplasia is a hereditary disease characterized by congenital dysplasia of one or more ectodermal structures. Intraorally, common findings are anodontia or oligodontia, conical teeth, and, consequently, generalized spacing. This case presented the oral rehabilitation of a child with hypohidrotic ectodermal dysplasia. Oral rehabilitation is important from functional, esthetic, and psychologic perspectives. Due to the absence of teeth, the volume of alveolar bone and its growth are decreased, resulting in a loss of vertical dimension and protuberant lips. The treatment involved increasing the patient's vertical dimension of occlusion, fabricating a maxillary partial denture, and using magnets to help retain the mandibular partial denture. A 5-year 7-month old Korean boy was referred to the pediatric department for examination, evaluation and treatment of his disorder. we used magnets on '73 and '83 for enhanced retention of a mandibular overdenture. The magnet used in this case was the Magfit system(GC Co., Japan).
