Objectives: The purpose of this study was to examine the impact of chronic disease on oral health behavior. Methods: The subjects were 317 adults over 30-years old living in urban and rural areas. They were selected by convenience sampling method and filled out the self-reported questionnaire. The questionnaire consisted of general characteristics, dental treatment, chronic disease, and oral health behavior including oral health self-care behavior and professional oral health care. Results: The self-care oral health behavior and the professional oral health care had a negative correlation with the chronic diseases. Especially, the self-care oral health behavior and the professional oral health care had a statistically significant negative correlation with hypertension and osteoporosis. Multiple regression analysis was performed after including general characteristics, dental treatment, chronic disease. Meanwhile the presence of chronic disease had a significant influence on the self-care oral health behavior and the professional oral health care. Hypertension and Osteoporosis were the most influential factors of chronic diseases and had a significant influence on the oral health behavior. In conclusion, the chronic diseases aggravated the oral health behavior practice. Conclusions: presence of chronic disease affects oral health behavior. Therefore, the effective intervention and education programs related to oral health care are necessary to enhance adult's oral health behavior and total health. The continuous follow-up study will determine the causal relationship between oral health behavior and the presence of chronic disease.

Objectives : The purpose of this study was to examine the self-rated oral health concern of adults over the age of 20 and from all over the country and their subjective oral health symptoms in a bid to provide some information on oral health policy setting for adults. Methods : The subjects in this study were 3,558 adults who voluntarily participated in a survey conducted by this researcher at the website of a company. After their answer sheets were analyzed, the following findings were given: Results : 1. 81 percent replied that they were very concerned about oral health. As to the relationship between their general characteristics and oral health concern, there were statistically significant differences in that regard according to their gender, age, purpose of seeing a dentist and occupation. 2. As for the relationship of their general characteristics to subjective awareness of oral health symptoms, there were statistically significant gaps in that aspect according to their gender, age, purpose of seeing a dentist, occupation and state of smoking. 3. In regard to the relationship between oral health concern and subjective awareness of oral health symptoms, those who were more concerned about oral health felt less subjective oral symptoms, but the difference between them and the others was not significant. The respondents who felt more symptoms of dental caries felt more symptoms of periodontal diseases as well. Conclusions : The above-mentioned findings indicate that in order to help adults promote or maintain their oral health, their concern for oral health should be stimulated by providing them with a lot of diverse information, and it seems that the development of programs that can eliminate their subjective oral symptoms of dental caries and peridontal diseases, the primary causes of tooth dysfunction, is required.

The lack of sufficient oral mucosa available for intra-oral reconstruction has been dealt with by the use of skin or oral mucosa grafts harvested from donor sites but grafts requires more than one surgical procedures and could cause donor site morbidity. Many investigators have attempted to increase available soft tissue by tissue engineered skin or oral mucosa replacements for clinical applications. But, reconstructed mucosa by several methods have low physical properties such as rolling and contraction. The aims of this study were to develope an in vitro experimental model that maintains an epithelial-mesenchymal interaction by organotypic raft culture, and to characterize biologic properties of three-dimensionally cultured oral mucosa embedded with Polydioxanone mesh by histological and immunohistochemical analysis. The results were as follows; 1. Oral mucosa reconstructed by three-dimensional organotypic culture revealed similar morphologic characteristics to equvalent normal oral mucosa in the point that they show stratification and differentiation. 2. The expression of cytokeratin 10/13 and involucrin in the cultured tissue showed the same pattern with normal oral mucosa suggesting that organotypic co-culture condition is able to induce cellular differentiation. 3. After insertion of polydioxanone mesh, increased tensile strength were observed. These results suggest that three-dimensional organotypic co-culture of the oral mucosa cell lines with the dermal equvalent consisting type I collagen and fibroblasts reproduce the morphologic and immunohistochemical characteristics similar to those in vivo condition. And increased physical properties by use of polydioxanone mesh will helpful for clinical applications.

Purpose: To evaluate the characteristics of (widely used) cone beam computed tomography (CBCT) images. Materials and Methods: Images were obtained with CT performance phantoms (The American Association of Physicists in Medicine; AAPM). CT phantom as the destination by using PSR $9000N^{TM}$ dental CT system (Asahi Roentgen Ind. Co., Ltd., Japan) and i-CAT CBCT (Imaging Science International Inc., USA) that have different kinds of detectors and field of view, and compared these images with the CT number for linear attenuation, contrast resolution, and spatial resolution. Results: CT number of both PSR $9000N^{TM}$ dental CT system and i-CAT CBCT did not conform to the base value of CT performance phantom. The contrast of i-CAT CBCT is higher than that of PSR $9000N^{TM}$ dental CT system. Both contrasts were increased according to thickness of cross section. Spatial resolution and shapes of reappearance was possible up to 0.6 mm in PSR $9000N^{TM}$ dental CT system and up to 1.0 mm in i-CAT CBCT. Low contrast resolution in region of low contrast sensitivity revealed low level at PSR $9000N^{TM}$ dental CT system and i-CAT CBCT. Conclusion: CBCT images revealed higher spatial resolution, however, contrast resolution in region of low contrast sensitivity was the inferiority of image characteristics.
