Atrophic alveolar ridge of maxillary anterior area is commonly observed after the extraction of teeth in patients with severely compromised periodontal disease, causing difficulties with implant placement. Successful esthetics and functional implant rehabilitation rely on sufficient bone volume, adequate bone contours, and ideal implant positioning and angulation. The present case report categorized the ridge augmentation techniques using guided bone regeneration (GBR) on the maxillary anterior site by Seibert classification. Case I patient presented for implant placement in the position of tooth #11. The alveolar ridge was considered a Seibert classification I ridge defect. Simultaneous implant placement and GBR were performed. Eight months after implantation, clinical and radiological examinations were performed. Case III patient presented with discomfort due to mobility of the upper maxillary anterior site. Due to severe destruction of alveolar bone, teeth #11 and #12 were extracted. After three months, the alveolar ridge was considered a Seibert classification III ridge defect. A GBR procedure was performed; implantation was performed 6 months later. Approximately 1-year after implantation, clinical and radiological examinations were performed. During the whole treatment period, healing was uneventful without membrane exposure, severe swelling, or infection in all cases. Radiographic and clinical examinations revealed that atrophic hard tissues and buccal bone contour were restored to the acceptable levels for implant placement and esthetic restoration. In conclusion, severely resorbed alveolar ridge of the maxillary anterior area can be reconstructed with ridge augmentation using the GBR procedure so that dental implants could be successfully placed.

A 49 years old male patient was referred from the Department of Medicine, KNUH for the management of painful oral lesions. The patient had disability of food and drug intake due to multiple intraoral ulcers. Extraoral findings showed upper and lower lip swelling, crust formation on the lips. The lesions were diagnosed as Stevens-Johnson syndrome based on clinical and hematologic findings. The patient was treated with saline irrigation and pulsed Nd:YAG laser irradiation. After 5 daily treatment, the lesions decreased in size and severity, and the patient became more comfortable for food intake and speeching. It was suggested from the results of this clinical trial that a pulsed Nd:YAG laser therapy would be helpful for the symptoms associated with Stevens-Johnson syndrome.

Recently, there are three major trends in building school facilities by government. First trend is to reconstruct facilities that have been built for 30 years. Second is the creation of a new town, new construction demanded from the redeveloping area. Finally, third is to build educational convenience facilities such as gymnasium, auditorium and cafeteria etc. When building or reconstructing school facilities, it is important to consider the 7th Education curriculum. The purpose of this study is to propose the guide line of the planning the dimension of Science Laboratory in in elementary school, corresponding to teaming contents and method.

Objective : The purpose of this study is to report a case of lacquer allergy improved by Korean medicine treatment. Methods : The patient visited our hospital complaining of rash, and pruritus which lasted for 10days after eating lacquer chicken. Considering that patient's symptoms occurred due to food allergen, we prescribed Injinho-tang(Yinchenhao-tang) and acupuncture at Daejang-Junggyeok for 7days. Results : On the 4th day of treatment, pruritus decreased to less than half of the initial treatment, and skin symptoms also improved to a mild level. About a week later, most of the skin symptoms disappeared (Total Objective Symptom score decreased 10 to 3), and subjective symptoms such as pruritus improved to about 30% of the time of the first visit (Total Subjective Symptom score decreased 12 to 3). Conclusions : After 7days of Korean medicine treatment, lacquer tree allergy with skin lesions and pruritus has improved considerably.

Papillary thyroid carcinoma (PTC) typically has a good prognosis, but it frequently metastasizes to the regional lymph nodes. Although survival impact of lymph node metastasis is not clear, complementary treatment is generally added after surgery when lymphatic metastasis exists. Several previous studies have reported that the multifocal PTC is associated with poor prognosis and requires selective neck dissection to prevent regional lymph node metastasis, but they are under controversy. In this study, we present a 24-year-old female patient, diagnosed as PTC with intrathyroidal spread and regional lymph node metastases. Intrathyroidal spread of PTC can only be observed microscopically and is believed to have the similar origin of unicentric multifocal PTC. As multifocal PTC is highly associated with regional lymph node metastasis and requires an additional treatment, PTC with intrathyroidal spread may follow a similar clinical course and treatment plan. Here we report the case with a brief literature review and expect its attribution to further academic interest of treatment choice.
