Ectopic eruption should be understood as a change in the course of the normal eruption path of a dental bud at any moment in its origin. Transposition is a unique and extreme form of ectopic eruption. The treatment for ectopic eruption and transposition is various from simple observation to surgical exposure and orthodontic traction, according to direction of erupting tooth degree of developing root apex and eruption space etc. Autotransplantation is transplantation of tooth from one area of the mouth to another in the same individual or is moving a eruption tooth into extraction socket or surgically prepared socket, and autotransplantation is considered as a treatment of choice for the ectopic eruption when orthodontic traction is unable or when tooth movement is limited. These cases which were treated with autotransplantation of maxillary lateral incisor and maxillary canine were reported, and good esthetic and functional result were induced.

Impacted mandibular canines are less common than impacted maxillary canines. The proceeding studies show that impacted mandibular canines occur in approximately 0.1% of patients examined. The causes of impacted mandibular canines are inadequate space, premature loss of the primary dentition, excessive crown length, hereditary factors, functional disturbances of endocrine glands, tumors, and traumas. The basic choices for treatment of those cases are orthodontic migration or surgical removal. This is a case report about those two different treatment methods. One patient was 11 years old female who had treated with surgical approach and the other was 14 years old male who had received orthodontic treatment.

Orthodontic problems of the oral maxillofacial area could be classified into skeletal and dental problems. Dental problems might cause various occlusal disharmony and among them congenital missing or eruption failure might cause not only functional problems but also esthetic problems. Additional psychological problems are also one of the reasons for patients seeking treatment. In cases showing eruption failure of many teeth in the maxilla, not only occlusal and esthetic problems but also difficulty in alveolar bone maintainment could occur. Therefore, successive approach is necessary when multiple teeth show eruption problems. In this case, a patient with eruption problems of #13, 12, 11, 23, 43 was successfully treated by surgical exposure and successive orthodontic extrusion resulting perfect occlusion. By additional periodontal treatment, gingival recession that occurred along with teeth eruption was solved. The impacted right mandibular canine was erupted successfully only by natural arch expansion and leeway space without any special surgical treatment.

This study was aimed to identify surgical ward nurses' importance-performance awareness toward early mobilization after abdominal surgery patients. The date were collected from 162 nurses and the importance and performance of early mobilization were analyzed by the IPA method. The collected data were analyzed using the SPSS/WIN 25.0 by implementing descriptive statistics, independent t-test, paired t-test, and ANOVA. Early mobilization was divided into exercise of pulmonary complications and early ambulation. As a result of the study, the areas requiring concentration were 'check risk of aspiration', and areas requiring improvement were 'oral care', 'check lung sound', 'percussion/vibration', 'suction', and 'reinforcement exercise in bed'. Therefore, each item of early mobilization is recommended to reduce the gap between importance and performance in clinical care.

Germ-line mutations at DNA repair loci confer susceptibility to colon cancer in hereditary non-polypopsis colorectal cancer. Somatic loss of DNA mismatch repair gene has been reported in a large variety of other tumor types. Replication errors(RERs) judged by microsatellite instability(MSI) and its associated mutations have been recognized as an important mechanism in various tumor types. To investigate associations between MSI and oral squamous cell carcinoma, the frequency of MSI using 12 microsatellite markers were analyzed for the series of oral tumors. Of 17 tumors, 8 cases(47%) did not show instability at any of the 12 loci; 5(29%) showed instability at $2{\sim}3$ loci; and 4(24%) showed instability above 4 loci. The 4 cases showing widespread MSI did not differ from those without evidence of instability in terms of age at diagnosis, degree of differentiation, metastasis to lymph node, tumor location or the presence of mutations in the p53 tumor suppressor gene. DCC and D17S 796 were the most frequently detected in MSI analysis. There were no correlation between smoking and MSI frequency, instead, smoking was suggested to increase the mutation rate of p53 and development of oral carcinomas.

This study was aimed to investigate the practice on the infection control and dental waste disposal in dental clinic. The data used in this study had been collected in 100 dental clinics located in Seoul city from August to October, 2001. It was shown that examination instruments, oral surgery instruments, and periodontal instruments were almost sterilization in dental clinic. It was high in the recognition of individual protection but it was low in the degree of practice. Therefore, the practice in infection control is very important to dental team for safety of patients and operators.

The clinical institution of some dental hygiene students and the degree of practice and performance according to the practice contents are identified, so as to develop clinical practice guidelines and to improve the education of universities and practical institutions. From November 2016 to March 2017, the questionnaire was prepared by self-inclusion after explaining the purpose of research and how to prepare questionnaire to some dental hygiene students. This material has been analyzed using PASW Statistics 18.0. As for the clinical practice content items of basic care and infection control, the frequency of "execution" among practice methods was high, and the distribution rate was high in oral evil face radiation, preventive dentistry, prosthesis, periodontology, orthodontics, and oral internal medicine. The conservation department has conducted various practical methods such as "executing," "observing" and "preparing." Oral surgery showed similar distribution rates, such as "observation," "preparation," and "execution" in the "preparation and cooperation of the feet." In pediatric dentistry, "observation" was the most common practice, and among them, "observation," "preparation," and "execution" were performed in "preparation and cooperation for infantile development." In addition, students with more experience in clinical practice showed statistically significant differences in basic care, oral hygiene, preventative dentistry, conservation, dental dentistry, oral surgery, orthodontics, and oral internal medicine(p<0.05). Most clinical practice shows that it is more observable than performed.It is expected that the goal of clear clinical practice content should be set by grade or number of clinical practice experiences, as well as the practice method that can be performed by the trainees.

As the increased certainty of osseointegration, new parameters are now being used to assess implant success. Accordingly, patients' and clinicians' high demands and expectation for esthetics have expanded and implant-supported restorations show better esthetic outcomes. The pre-implant treatment planning process, the implant surgical steps and the post-surgery prosthetic process can affect all esthetic outcomes. Prevention of esthetic implant failures can be achieved by appropriate treatment at each stage, considering the 3 factors of alveolar bone, soft tissue, and implants. It is necessary to achieve the esthetic implant prostheses followings: minimal invasive surgery, bone augmentation, ideal 3-dimensional implant position, peri-implant soft tissue management, and provisional restorations to optimize peri-implant soft tissue architecture.

Behest's disease is manifested as ulcers present in oral cavity, on external genital organ, orbital area, and skin. This disease could also cause other symptoms by invading the cardiovascular system, respiratory system, gastrointestinal system, central nervous system, and urogenital system. It is very rare for Behcet's disease to be accompanied by carotid artery aneurysm and intestinal perforation. We report a patient with Behcet's disease, who is diagnosed with symptoms and pathological findings as haying carotid artery aneurysm and intestinal perforation at the same time. The patient underwent operation for the aneurysm and the intestinal perforation.

A clinico-statistical study was made of 237 case, 186 male and 51 female of oral and maxillofacial malignant cancer patients at Presbyterian Medical Center in Chon-ju between 1984 January and 1988 December. In 204 cases of the carcinoma, 154 cases were pathologically diagnosed as squamous cell carcinoma. More than 65% of the cases were clinically adbanced cases (stage III or IV), and 154 cases of 237 cases were treated. Most cases were treated by surgery (S)+radiation (R)+chemotherapy (C) or S+R or R+C. The expired cases were 20 cases. 11 cases of them were found in stage III.
