This study was to investigate their relevance between oral health behaviors and number of remaining teeth of the elderly welfare recipients through the fluoride and scaling of the business. Researcher collected 660 subjects over 60 elderly welfare recipients investigated self-administered survey and use denture and number of remaining teeth though oral examination. Increasingly age number of teeth remaining reduced, there is a difference on the number of remaining teeth according to gender, age, the use of oral hygiene products, self diagnosis oral condition, brushing after lunch and showed significant difference(p<0.05). The remaining number of teeth can be prevented by attention and efforts of subjects. Therefore, we investigated convergent effects of oral health behaviors on number of remaining teeth of the elderly, I hope that oral health care program continually provides expansion of preventive treatment and to maintain the provision of health care about vulnerable group.

Recently, with the population growth of elderly people, concerns about oral health related to the quality of life of the elderly are increasing. The purpose of this study is to assess the association between the elderly women divided into dementia, suspected dementia, healthy groups and the remaining teeth of them. Total 177 elderly women of over 60 years old, visiting on senior center in some community dwelling, were assessed for oral condition and their cognitive function with MMSE score. All the collected data were analyzed by chi-square test, t-test, and multiful logistic regression using SPSS. Multiful logistic regression was used to analyze the relationship of dementia according to MMSE score and remaining teeth, and 95% confidence intervals were computed. Odds ratio(OR) of the number of remaining teeth 0-10 was 3.43 (95% confidence interval: 1.382-8.997). This study showed significant difference and the relationship between dementia according to MMSE score and the number of remaining teeth of the elderly women.

Wolf teeth have been reported with incidence rate of 13% to 31.9% in horses of both sexes. However, there is no report about the incidence of wolf teeth in pony breeds. In order to determine the incidence of wolf teeth in Jeju Ponies and Jeju Pony crossbreds, oral examination and palpation of the interdental space of ponies at the Jeju Race Park were performed from 2006 to 2010. Results of this study showed that a total of 90 (3.4%) of the 2,675 examined Jeju Ponies and Jeju Pony crossbreds had wolf teeth. Among 30 Jeju Ponies that had wolf teeth, 22 were male (73.3%) and 8 were female (26.7%). Among 60 Jeju Pony crossbreds that had wolf teeth, 25 were male (41.7%) and 35 were female (58.3%). In Jeju Ponies, wolf teeth were most common in 3-years-old, followed by ${\geq}4$-years-old, then 2-years-old. For Jeju Pony crossbreds, wolf teeth were most common in 3-years-old, followed by 2-yearsold, then ${\geq}4$-years-old. In conclusion, the incidence of wolf teeth in Jeju Ponies and Jeju Pony crossbreds was considerably lower than what has been reported for horses in other countries.

Loss of posterior support may cause overloading and excessive wear of remaining teeth. Moreover, the extrusion of antagonistic teeth leads to the destruction of the occlusal plane. The loss of vertical dimension of occlusion (VDO) also emerges clinically, which may bring the loss of esthetic appearance and function. These patients who suffer from the loss of posterior support, often require vigorous periodontal treatments (osteotomy, crown lengthening) and extensive oral rehabilitation. Sixty three years old female patient visited for the prosthetic treatment of the posterior edentulous area. She had no other systematic disease and parafuctional habits for prosthetic treatment. Intraoral and radiographic examinations were done. The evaluation of VDO and vertical dimension of rest position were evaluated for proper prosthetic procedures and diagnostic wax up was done. As a result of diagnosis, VDO was increased by 2 mm considering the loss of VDO and space for the prosthetic treatment. After the pretreatments, initial preparation of teeth and provisionalization were carried out. Six weeks later of provisionalizaion, final preparation and impression was performed. Using the duralay resin copings, jaw relation was registered. The master cast was mounted and definitive restoration was fabricated. After the evaluation of esthetic and function, pick up impression for clinical remounting was done. Lucia jig was made for new jaw relation and occlusal adjustment on the articulator. Definitive restoration was delivered and the patient was periodically recalled for additional occlusal adjustment. From this case, the satisfactory functional and esthetic results through full mouth rehabilitation with increase vertical dimension were achieved.

The aim of this study was to investigate the relationship between the oral health status of elderly under visiting health care and their oral health-related quality of life. The subjects were 300 elderly under visiting health care program over 65 years old in Asan city and they were interviewed. The result showed that average Geriatric Oral Health Assessment Index (GOHAI) score was 37.36 and the lowest scored question was 'never satisfied with the oral condition'. In GOHAI related to oral health behaviors, unmet dental treatment experience was statistically significant (p<0.001). In overall GOHAI, number of remaining teeth (p<0.001) and the age had statistical significance and men had higher score in pain and discomfort (p<0.05), under age of 74 limited function factors score was high (p<0.01). The number of remaining teeth had statistical significances in most factors except pain and discomfort (p<0.001). The factors affecting GOHAI were age (p<0.05), number of remaining teeth (p<0.001) and perceived health state (p<0.001). In order to improve oral health-related quality of life of elderly receiving visiting oral health care services, it is necessary to increase denture support by securing budgets and developing oral health promotion programs at the local government level.

In the case of the impacted teeth, the clinician has to consider development of tooth, site of impaction, eruption path, and cooperation of patient. Treatment options for the management of impacted teeth are separated into four categories: observation, intervention, orthodontic or surgical relocation and extraction. Autotransplantation may be defined as the transplantation of embedded, impacted or erupted teeth, from one site to another in the same individual into extraction site or surgically prepared sockets. Autotransplantation ensures preservation of natural tooth, induction of alveolar bone growth and root development, offers one of the fastest and most economically feasible means in the replacement of young patients' missing teeth. This case presents a malpositioned impacted mandibular premolar of an 11-year-old girl. It was thought that orthodontic traction was difficult because of its unfavorable impacted position. Therefore the tooth was treated by autotransplantation, we can observe good healing pattern during 12 months.

Tooth eruption involves a complex developmental process of tooth migration from the dental follicular origin to the final occlusion position in the oral cavity via the alveolar process. Disturbance of tooth eruption can occur at any point in a series of eruption stages; however, horizontal impaction of the mandibular first molar and primary retention of the primary mandibular second molar are rarely observed simultaneously. This study describes the treatment for two cases of horizontally impacted first molar with primary retention of primary molar. The primary retention of the primary mandibular second molar was extracted, and orthodontic traction was applied to the horizontally impacted primary mandibular first molar. Subsequently, displacement of the premolar tooth bud was improved and space regaining for eruption was achieved, guiding to normal eruption of the first molar.
