This study developed key elements of dental service guidelines for the disabled patients. In order to provide consumer-oriented service guidelines for the dental patients with disability, service design method was applied. Using service design method guided by the double diamond design process, this study implemented consumer survey, observation, and contextual interviews for consumers' needs assessment. And customer journey map, mind maps, and blueprints were utilized to visualize consumer needs and guidelines for dental care services for the disabled. According to the study, disabled consumers have needs for expertise of the medical staff, dental care institutions specialized on the disabled, financial support, establishment of the facilities for the disabled, comfortable atmosphere in the institutions, and communication with medical staffs. Based on the needs of the disabled, 5 key elements of the dental care services were developed: convenience, expertise, empathy, financial support, and education and management. And service design guidelines were proposed to implement key elements of dental care services for the patients with disability. This study is significant in that it is the first attempt to apply the service design technique from the consumer perspectives in the field of dental care for the disabled. Furthermore the process of this study has become a reference that can be utilized and applied to other medical institution.

Objectives: The purpose of this study was to investigate effective predictive factors of the persistence of unmet dental care needs. Methods: Data were obtained from the Korea Health Panel studies of 2011 and 2015, and 4,406 subjects, aged 18 years or older, were included in this study. Of these subjects, those who persistently experienced unmet dental care needs over the three-year period were identified. Panel logistic regression analyses were conducted to identify socio-demographic and health-related factors associated with the persistence of unmet dental care needs in two groups, those aged between 18-64 years and over 65 years. Results: Approximately 12% of subjects showed a persistence in unmet dental care needs. Marital status, education level, household income, type of health insurance, and self-rated health status all significantly correlated with the persistence of unmet dental care needs in both age groups. Conclusions: Efforts should be made to identify factors related to the persistence of unmet dental care needs in order to improve patient accessibility to dental care services.

Background: The options for stabilization appliance therapy for masticatory muscle pain include soft occlusal and hard stabilization appliances. A previous study suggested that hard stabilization appliance therapy was effective for patients with local myalgia who developed long facets on their occlusal appliances. The objective of this study was to identify patients in whom a soft occlusal appliance should be used to treat masticatory muscle pain by analyzing the type of muscle pain present and patient factors that influenced the effectiveness of this treatment. Methods: The study included 42 patients diagnosed with local myalgia or myofascial pain according to the Diagnostic Criteria for Temporomandibular Disorders Diagnostic Decision Tree. The analysis of patient factors included variables believed to be associated with temporomandibular disorders. First, a temporary screening appliance was used for 2 weeks to assess each patient for bruxism during sleep. Soft appliance therapy was then started. For each patient, the effectiveness of the appliance was evaluated according to the intensity of tenderness during muscle palpation and the treatment satisfaction score at one month after starting treatment. Results: Data from 37 of the 42 patients were available for analysis. Twenty-five patients reported satisfaction with the appliance. In logistic regression analysis, the odds ratio for reduction of facet length was 1.998. Nineteen patients showed at least a 30% improvement in the visual analog scale score. The odds ratio for local myalgia was 18.148. Conclusion: Soft appliance therapy may be used in patients with local myalgia. Moreover, patients who develop short facets on the appliance surface are likely to be satisfied with soft appliance therapy. Soft appliance therapy may be appropriate for patients with local myalgia who develop short facets on their occlusal appliance.

The role of radiographic imaging in determining the size, numbers and the position of implants is very important. To perform the implant procedure, the dentist needs to evaluate the bone pathology and bone density, and to know the precise height, width, and contour of the alveolar process, as well as its relationship to the maxillary sinus and mandibular canal. The author analyzed 3 implant cases for treatment planning with the cone beam CT. All axial, panoramic, serial and buccolingual-sectioned images of 3 cases with stent including vertical marker were taken by using Mercuray (Hitachi, Japan). When the curved line drawn intentionally did not include dot image of a vertical marker on the axial image of CBCT, the image of the vertical marker was deformed on its buccolingually sectioned image. There was wide discrepancy in inclination between the alveolar bone and tooth on buccolingually sectioned image.

An opportunity for dental students to come into contact with individuals with disabilities is insufficient. Therefore, prejudice and negative attitudes towards persons with disabilities persist. Working under the assumption that educating dental students regarding people with disabilities will bring about positive awareness, we conducted this study. We investigated the changes in the recognition of the issues and needs of people with disabilities before and after special care dentistry class of students of dental college that will include an experience in a dental clinic with a disabled person. Seventy-two Kyung Hee University School of Dentistry third-year dental students attended the special care dentistry class in one semester and they took the same survey was before and after the class. In the questionnaire, we used the disability factor scale (DFS) that Siller has proposed. The authoritarian virtuousness factor getting lower to a significant level after receiving an education. This means that after the education, the respondents realize that how hard to adapt the disabilities. After receiving an education, the rejection of intimacy factor score significantly get higher than before they took the class. This means that after the training, positive attitudes towards those with disabilities were better than those towards the opposite sex. We were able to confirm a positive change in the recognition for persons with disabilities through the special care dentistry class. Our study shows that educating dental students on the how to take care of individuals with disabilities can bring about a positive change in the attitudes students may have regarding them.

Occupational Dentistry was introduced in Korea about 70 years ago. During the colonial period occupied by Japan till 1945, there were few documents about industrial dentistry, furthermore most cases of occupational diseases and accidents might have been concealed intentionally by the colonial government. After being an independent country, several dentists made efforts to set up 'Preventive Dentistry for Workers' performing specific oral health surveys, even though which were stopped by Korean War. In 1960s' and 1970s', some investigations of oral status were carried out intermittently for specific small groups;white-collar workers, mentally retarded person, buddhist monks and crews of ocean liners. At the same time there was important study in Korean history of occupational dentistry, which was 'a comparison of the oral hygiene conditions in the female workers of a spinning factory at intervals of 30 years.' In 1980s', young researchers began to give attention to erosion of the teeth due to sulphuric acid in the acid-related industry and dental caries due to sugar and flour in the sweets industry. After being democratic labor union movement activated in 1987, hidden and suppressed occupational diseases under the military dictatorship were exposed and flushed in the newspapers. It was shocking for all people that 15-year old boy had been dead due to mercury intoxication after 3-month employment in 1988. In 1990s', the activity for studying oral status of workers in their workplaces was launched and 'Occupational Accidents and Diseases in Oral and Maxillofacial Field' was published. And also The Korean Association of Occupationl Dentistry was established. Oral health examination of workers at the time of employment and of workers exposed to 5 special chemicals at the time of routine special health examination was adopted in 1992, and epocally oral health examination was also included in periodic routine examination of workers' health in 1995. So, occupational dentistry in Korea should cope with the changing needs of working environment and the altering scheme of health examination.

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a disease characterized by jaw necrosis and delayed wound healing in patients who had received bisphosphonates. Buccal fat pad (BFP) can be used as a pedicled flap in the posterior region of the oral cavity. BFP pedicle flap needs simple surgical technique and it shows less donor site morbidity and aesthetic problem than other vascularized flap. BFP pedicled flap was fed by 3 arteries-facial, internal maxillary, and transverse facial artery. Osteomyelitis was generally related with poor blood supply. Thus, rich blood supply of BFP pedicle flap can have a potential advantage to BRONJ patients. In this case report, we presented 3 BRONJ patients treated by BFP pedicle flap after sequestrectomy.

General anesthesia is commonly used to facilitate dental treatment in patients with anxiety or challenging behavior, many of whom are children or patients with special needs. When performing procedures under general anesthesia, dental surgeons must perform a thorough pre-operative assessment, as well as ensure that the patients are aware of the potential risks and that informed consent has been obtained. Such precautions ensure optimal patient management and reduce the frequency of morbidities associated with this form of sedation. Most guidelines address the management of pediatric patients under general anesthesia. However, little has been published regarding this method in patients with special needs. This article constitutes a review of the current literature regarding management of patients with special needs under general anesthesia.

Purpose: The purpose of this study is to induce artificial arthritis on rabbit TMJ by injecting collagenase. Materials and Methods: An experimental animal model of arthritis induced by surgical method or intraarticular injection of chemical agent like LDH, papain, ketorolac. Surgical method is complex and needs a long time in inducing arthritis. Intra-articular injection of chemical agent like LDH, papain, ketorolac is simple. But chemical agent like LDH, papain, ketololac needs multiple injections to induce arthritis and mechanism inducing arthritis was known. Collagenase destroys helical domain of type II collagen in extracellular matrix produced by chondrocyte and then induces arthritis. We injected collagenase (0.5, 1.0, 2.0 mg) into the temporomandibular joint of rabbit. In the control group saline was intra-articularly injected. The condylar cartilage, disk and synovia were histologically examined at 1, 2, 4, 6 weeks after the initiation of collagenase injections. Results: Four weeks after injection of 2.0 mg collagenase, we could see histologic change like arthritis. In other groups, we couldn't see arthritis-like change. Conclusion: In our study, we produce arthritis on temporomandibular joint of rabbit by using injection of collagenase in temporomandibular joint of rabbit. And this experimental osteoarthritis is a useful animal model.

Childrens between the ages of 13 and 15 years, living in Seoul, were examined in order to determine the prevalence and severity of malocclusion in the permanent dentition. This survey encompassed 981 children and an individual chart was prepared for each subject recording an original HMAR score and classification of occlusion according to Angle. Also, subjective evaluation of "treatment needs" was carried out in 581 children. The results were as follows: 1. Of the 981 children in this survey, 12,1 percent showed excellent occlusion. (0 point) 2. The 14 percent of the children who had a score of 24 and above all appeared to belong to the "treatment highly desirable" or "treatment mandatory" category. 3. The incorporation of SAR (Supplementary Assessment Record) into the HMAR can provide more sensitive method for evaluating severity of malocclusion. 4. According to Angle's classification 77.4 percent of all malocclusion belonged to Class I, 1.3 percent to Class II, Division 1, 0.9 percent to Class II, Division 2, and 11.3 percent to Class III. 5. The mean HMAR score for Class I was significantly lower than for either Class II, Division 1 or Class III. (P < 0.05) 6. A close relationship was found between the degree of "treatment needs" and the value obtained by the HMAR scoring. (chi-square test, p < 0.05) The differences between the mean HMAR scores of the various subjectively defined categories were statistically significant. (P < 0.001)
