I participated in Academic Exchange Program(Action plan II) between KADH(Korean Association for Disability and Oral Health) and JSDH(Japanses Society for Disability and Oral Health) for 2 months from 3rd July 2012 to 2nd september 2012 in the Department of Hygiene and Oral Health, School of Dentistry, Showa University at Tokyo, Japan. I have observed their operation process and learned what dysphagia is and how it is consulted and taken care of as a therapy for patients with eating and swallowing disorders for two months in The department of special needs dentistry at Showa University Dental Hospital, Jonan Branch of Tokyo Metropolitan Kita Medical Rehabilitation Center for the Disabled, Smile Nakano Center, Tokyo metropolitan center for persons with disabilities in Lidabashi for one week, Eating and swallowing functional therapy workshop for disabled children, Tokyo metropolitan Tobu medical center for Persons with Developmental/Multiple Disabilities located in Minamisunamitchi for one week and on The 17-18th JSDR(Japanese Society of Dysphagia rehabilitation) in Sapporo. Through Action Plan II program, I learned how precious eating, drinking and swallowing with ease are and observed how they do and what they do as a dentist or a dental hygienist in Japan for dysphagia patients. Therefore, I want to present the dental approaches of children with dysphagia in Japan, based on my experience for two months.

A salivary stone on mouth floor was removed in a 10-year-old girl with cerebral palsy and epilepsy. If left untreated, sialolithiasis can lead to inflammation of whole salivary gland with severe pain and inflammation that spread to other side of salivary gland causing damaging of teeth, abscess, and nerve disorders. Special needs patients have difficulty to express their pain or discomfort. To overcome communication problem and offer appropriate treatment in proper time, a careful and comprehensive clinical examination including soft tissue and tooth should be prioritized in special needs patients visiting the dental clinic.

This study was designed to investigate the status of orthodontic treatment and facial plastic surgery among 389 patients who visited dental clinics located in Seoul and Gyeonggi Province. After the collection of data, an analysis was carried out using a spss statistical program. The analysis results are as follows. the level of satisfaction with orthodontic treatment from patients with experience of the orthodontic treatment turned out to be high(p<0.01). Women considered 3.01 to 4 million won to be reasonable cost for orthodontic treatment (p<0.05), which is higher cost recognized by men, and patients with experience of orthodontic treatment recognized 19 to 24 months as the proper orthodontic treatment period(p<0.01). In addition, women showed higher figures than men in their awareness on the need for orthodontic treatment checkups(p<0.001), and facial plastic surgery experience (p<0.01). With respect to the part of the face on which they hoped to have plastic surgery, eye plastic surgery was higher in women (p<0.01), and nose surgery turned out to be higher in patients with experience of orthodontic treatment(p<0.05). Meanwhile, women considered the eye as the most important part among other facial areas (p<0.001), and they recognized that dentist should perform plastic surgery on both jaws among facial areas(p<0.01). In conclusion, the dental medical staff should provide consultations and operate treatment systems in consideration of gender differences and needs of dental patients. In the case of orthodontic treatment for the improvement of facial appearance, especially double jaw surgery which is closely related to the oral function, professional dental medical staff needs to perform the operation, considering the special oral environment. In addition, it is determined that provision of relevant medical information and promotion of dental service is required to provide patients with correct knowledge about orthodontic treatment and facial plastic surgery.

Sedation or general anesthesia is often required to offer dental treatment to patients with special needs. However, patients with ASA classification of III or higher are not indicated for moderate sedation and might be exposed to danger when treated at outpatient dental clinic. For this reason, it is recommended to treat those patients under general anesthesia. The dental team can supervise and monitor the whole procedures during treatment with an appropriately equipped facility. This case report describes the dental treatment of a 7-year-old girl with multiple disabilities. Preoperative evaluation including medical consultation was carried out thoroughly and dental treatment was performed under general anesthesia safely.

Purpose: Due to the difficulty of the hygienic care and sanitary management of abutment teeth and subpontic areas associated with fixed dental prostheses (FDPs), intrabony defects occur and accelerate due to the accumulation of plaque and calculus. This study aimed to evaluate the efficacy of regenerative periodontal surgery for intrabony defects associated with FDPs. Methods: The study inclusion criteria were met by 60 patients who underwent regenerative treatment between 2016 and 2018, involving a total of 82 intrabony defects associated with FDPs. Periodontal osseous lesions were classified as 1-, 2-, and 3-wall intrabony defects and were treated with an enamel matrix derivative in combination with bone graft material. The changes in clinical (pocket probing depth [PPD] and clinical attachment level [CAL]) and radiographic (defect depth and width) outcomes were measured at baseline and at 6, 12, and 24 months. Results: Six months after regenerative treatment, a significant reduction was observed in the PPD of 1-wall (P<0.001), 2-wall (P<0.001), and 3-wall (P<0.001) defects, as well as a significant reduction in the CAL of 2-wall (P<0.001) and 3-wall (P<0.001) intrabony defects. However, there was a significant increase in the CAL of 1-wall intrabony defects (P=0.003). Radiographically, a significant reduction in the depth of the 3-wall (P<0.001) defects and a significant reduction in the width of 2-wall (P=0.008) and 3-wall (P<0.001) defects were observed. The depth decreased in 1-wall defects; however, this change was not statistically significant (P=0.066). Conclusions: Within the limitations of the current study, regenerative treatment of 2- and 3-wall intrabony defects associated with FDPs improved clinical and radiological outcomes. Additional prospective studies are necessary to confirm our findings and to assess long-term outcomes.

Background: To explore the empathic abilities, communication competence, and attitudes toward the disabled, and to identify the relationship between these variables among female dental hygiene students. Methods: A self-administered questionnaire was used to collect data from 190 female students in their second and third year of study at the dental hygiene department of a university located in Gyeongsangnam-do province, South Korea, from September 2-11, 2020. Data were analyzed using descriptive analyses, t-test, analysis of variance, Pearson's correlation, and multiple regression using SPSS 20.0. Results: The participants' scores for empathic abilities, communication competence, and attitudes toward the disabled were 3.63, 3.69, and 3.54 points, respectively. A significant positive correlation was observed between empathic abilities and attitudes toward the disabled. Regarding the sub-elements of empathic abilities, the participants' attitudes toward the disabled had a significant positive correlation with the scales measuring their perspective-taking abilities and personal distress (p<.05). A positive correlation (p<.05) was observed between communication competence and attitudes toward the disabled. The students' attitudes toward the disabled were significantly influenced by the scale measuring their perspective-taking abilities (B=.210); those with a higher perspective-taking ability displayed more positive attitudes toward the disabled. Conclusion: Female dental hygiene students showed empathic abilities, which positively influenced their attitudes toward the disabled. Positive attitudes toward the disabled can contribute to improving the quality of medical services.

Autism is a developmental, neuropsychiatric disorder that begins in early childhood. A patient with autism seen in the dental office frequently may have many complications. Therefore, it may be needed to consider modified or alternative therapy for dental care of autistic patients. This is the case of a 16-year old boy who have autism. He came to the department of the pediatric dentistry, Yonsei University Dental Hospital, for evaluation and treatment of dentigerous cyst associated with impacted teeth(#33,34,35). Under daily hospitalization and general anesthesia, the cyst was enucleated with surgical extraction of #34 and autotransplantation of #33,35. And during the periodic dental followup, apexification of #33,35 was performed for periapical lesion and root maturity. At 2 year 6 months follow- up, now, bony healing was completed and there are some complications like external resorption of #33 and space loss of #34 area. Generally, the marsupialization has been widely recommended for treatment of dentigerous cyst. However, in this case, there is a little possibility of spontaneous eruption after marsupialization considering of patient's age, location and angulation of the impacted tooth, root maturity. And there is necessity to choose the treatment that has low recurrence risk and needs short-term follow-up for autism. Above all, poor oral hygiene and lack of cooperation for decompression treatment is a matter of primary consideration. Consequently, enucleation of the cyst was chosen for the final treatment plan in this case. It is important to consider the conditions that affect the eruption of a dentigerous cyst-associated tooth to predict the successful eruption and special health care needs of the patient when the treatment plan is settled.

The aim of this retrospective study was to evaluate the demographic characteristics of pediatric dental patients who underwent dental treatment under general anesthesia (DTGA) at the Seoul National University Dental Hospital from January 2011 through December 2020 and compare the patterns of repeated DTGA between dental patients with severe disabilities (DSD) and non-DSD (healthy or medically compromised patients without DSD). There were 1,857 DTGAs among 1,719 patients (mean age = 5.1 years; males = 59.3%; ASA 2 or above = 52.9%; DSD = 26.8%). Overall, 6.6% of patients underwent repeated DTGA, and the rate of repeated DTGA over a 10-year period was 7.4%. ASA 2 or above (p < 0.0001) and DSD (p < 0.0001) were more likely to undergo repeated DRGA compared to ASA 1 and non-DSD. At both GA1 and GA2, DSD received significantly more restorative treatment on permanent teeth than non-DSD (p = 0.002, p < 0.0001, respectively). There has been an increasing demand for DTGA in pediatric dentistry over the last 10 years. Regular check-ups and preventive oral health care are necessary for pediatric dental patients with severe disabilities to reduce the possibility of repeated DTGA.

Malocclusion occurs more frequently in Special Health Care Needed (SHCN) patients than those in general. As caregiver's needs for orthodontic treatment tend to increase, the dentist should know how to decide the extent of treatment. This case report is about orthodontic treatment for two SHCN patients; one patient with cerebral palsy, and another patient with autism. A 10-year-old patient with cerebral palsy showed protrusion and rotation of maxillary anterior teeth. To resolve his chief complaints and make better oral hygiene, he underwent orthodontic treatment using micro tube appliances for 6 months. Another 11-year-old patient with autism had anterior crossbite and showed space deficiency of #13 and chronic gingivitis because of poor oral hygiene. She underwent orthodontic treatment with maxillary skeletal expander, facemask and AP expansion appliance. After 18 months we found positive overjet and ended the treatment. When giving SHCNs orthodontic treatment, the extent of treatment can be chosen according to the patient's cooperative ability and the traits of disabilities. Before initiating orthodontic treatment, the caregivers should be aware of their limitations of the treatment. Since oral hygiene is crucial factor in every dental treatment, education of oral hygiene process for the caregivers and SHCN patient must be done before the orthodontic treatment.
