The propose of this study was to evaluate the effect of cellular activity on PDL cells dependent on intermittent and continuous compressive force by determining the alkaline phosphatase activity. An intermittent and continuous compressive forces were applied on PDL cells at the confluent stage. The alkaline phosphatase activity was measured on control and experimental groups every 24, 48, 72hours. The experimental group were consist of continuous and intermittent compressive group which were compressed by $300g/cm^2$ of diaphram pump. The intermittent compressive group was connected by timer which was worked on 10 minutes and off 10minutes. The results were as follows ; 1. The alkaline phosphatase activity of intermittent compressive group was lower than control group at 24 hours(P<0.05). 2. The alkaline phosphatase activity between each groups showed no significant differences at 48hours. 3. The alkaline phosphatase activity of continuous compresssive group was significantly higher than control group at 72 hours(P<0.01).

Patients who have a moderate periodontitis with pathologic tooth migration of maxillary incisors, it is necessary not only periodontal treatment for reduce periodontal inflammation, but also orthodontic treatment to teeth repositioning. For orthodontic treatment, it is necessary to apply less force and careful considerations of the center of resistance of the tooth and optimal force of tooth movement. At this time, the segmental arch applied only to the target teeth, is more effective and predictable, because applied force and direction can be controlled. In addition, to design the orthodontic appliance that can prevent the unwanted tooth movement that used as an anchorage is important. In recent years, various types of skeletal anchorage system have been used for preventing loss of the anchorage. We reported the patient who had extruded maxillary central incisor due to pathologic tooth migration, treated by a successful periodontal-orthodontic multidisciplinary treatment using an orthodontic appliance designed to apply less traumatic force and reduce an anchorage loss.

As the age increases, the oral cavity, that is, the teeth and periodontium, also begin to age, and accordingly, a preparation process is required. The preparation process is an important period for oral health management to start continuously with oral health education consisting of knowledge, attitude, and behavior from the 20s. Therefore, to design a clinical dental hygiene course for patients who visited a dental clinic in Gyeonggi-do and received continuous care in an oral health care room after treatment, we tried to analyze the data of the dental hygiene assessment. As a dental hygiene assessment tool, based on personal information and general medical history, dental visit experience, bleeding on probing(BOP), bad breath measurement, phase contrast microscopy, and O'Leary index were performed. The number of subjects who had dental visits was 75.4% and those without experience were 24.6%, and as a result of the periodontal examination, generally bleeding was found in 76.3%. In preventive oral care, the stage of dental hygiene assessment in the 20s is an important first step. From this point on, it is an important time to be systematically habituated so that you can take responsibility for your own oral condition. Therefore, in this study, the results of dental hygiene assessment through oral examinations of subjects in their 20s are derived and presented as basic data for the development of dental hygiene performance competency of dental hygienists during the clinical dental hygiene process in oral health education and oral health management.

The purpose of this study is to figure out and establish the basic data that can help improve management of oral healthcare for the international marriage migrantwomen. In this sense, we surveyed questions on 237 women out of 1,300 immigrant women, who have participated the program in operation by multi-cultural household supporting center, in a fashion of face-to-face investigation and on-the-spot direct cavity inspection simultaneously from May 1th to October 31th, 2010. Collected data were electro-statistically computerized under SPSS 17.0 program and analyzed with frequency analysis, recurrence analysis and logistic regression analysis respectively. Foundings were revealed as follows; On the nationality base, show the data in the ratio of 38.8% for Vietnamese, 29.1% for Philippine, 12.2% for Chinese and 6.8% for Japanese respectively. Current oral cavity status shows in the ratio of 60% with carious tooth symptoms, 40% without carious tooth symptom. Philippine women have irregular sets of tooth in many a case. (i.e., in short of numbers of teeth, due to removing individual tooth.) Japanese ladies are indicated to have less irregular sets of tooth, in comparison with that of the other immigrants from overseas. And lastly, high-income immigrant women in general were found having less numbers of unhealthy sets of tooth. Getting older, it appears that decayed tooth symptom is on the tendency of getting less in the field of dentistry circles. Immigrant ladies living with husbands under higher education background usually are found living a life in the less ratio of having toothache. A full-time immigrant housewives, however, are living everyday life in more times of suffering with tooth disease.

The purpose of this study is to compare the quality of life for oral health between dental hygiene students and non-dental hygiene students in some areas and to analyze the factors affecting on it by using oral health impact profile-14 (OHIP-14). This study was carried out by surveys. Subjects for study were 248 undergraduate students, subjectively recognized oral health condition by subjects were periodontal disease and bad breath, and non-dental hygiene students recognized statistically significantly higher than dental hygiene students (p<0.001). Among the detail factors of OHIP-14, factor of decreased social ability was the lowest impact factor (p<0.01). The most influential factor on OHIP-14 was gender and age, grade of school and alcohol intake were influential in order (p<0.01).

Background: This study examined the oral health condition of diabetic patients and evaluated the oral health behavior through a questionnaires survey. In addition, this study provide primary informations for developing a dental health program for diabetic patients. Materials and Methods: There were fifty patients with diabetes mellitus or glucose tolerance (controlled by a community health center at Dalsung-Gun in Daegu City and fifty nondiabetic age, gender and location matched control subjects. Data were collected by a direct oral examination and by questionnaires from 100 subjects in July, 2004. Results: The DMFT (Decay, Missing, Filling Teeth) mean values in diabetics were significantly higher than that in non-diabetics (p<0.05). The decay teeth index and Filling teeth index was similar in the two groups, but the mean Missing teeth index was significantly higher in the diabetics than in non-diabetics. The PI (Periodontal Index) mean values were significantly higher in the diabetics than in the non-diabetics (p<0.01). There was a significant difference between the diabetics and non diabetics aged in their 50s and 60s, but there was no difference with those aged in their 70s. The oral hygiene status was similar in the two groups. The average number of remaining teeth was significantly lower in the diabetics ($16.1{\pm}10.35$) than in the non-diabetics ($20.04{\pm}8.70$) (p<0.05). Conclusion: In the diabetic patients, the M component of the DMFT index was found to be higher than the controls. Diabetics lose their teeth mainly due to periodontal disease, which is supported by the increased PI mean values.

The purpose of this study was to ascertain the breeding efficiency in Thoroughbred mare. A total of 106 mares were investigated for the status of follicle (462 cases), ovulation (179 cases) and pregnancy (346 cases). Of total examination, 46.8% was follicle measure to determine breeding time, and mating rate per cases examined was 39.9%. There was no correlation between reproductive results and size of follicles or endometrial edema or degrees of teasing alone. 143 cases were ovulated among 179 cases which were performed ovulation examination, and ovulation rate and fertilization rate per mating times were 79.9% and 39.0%, respectively. The use of hCG(human chorionic gonadotropin), to facilitate ovulation, presented to increase occurrence of double ovulations and twin fertilizations In conclusion, though more examination to estimate the optimal breeding time and higher mating rate was performed, fertilization rate per mating times was lower and then reproductive efficiency also became decreased. Therefore, it seemed that accurate examination of reproductive tracks, appropriate teasing programme and hCG administration before ovulation were of help to improve ovulation rate and fertilization rate.
