Objectives : For investigating relationship between oral condition and body mass of adolescent period and helping to make basic data which make oral care systematically while performing health care for adolescent. Methods : This research was carried out by performing oral and physical test of 273 high school students in some reasons from July 2nd to 16th in 2012. Results : There were significant differences, since the more subjects had irregular occlusion, the more they had loosing tooth(p<0.05). There was a significant difference, since when subjects had more numbers of regular occlusion, they had higher BMI and heavier weight.(p<0.001). There are significant different, since when the subjects had worse peridontal condition, they had more numbers of DT(p<0.001). There was a significant difference in occlusion and body mass group, since when subjects had regular occlusion, 46.4% of subjects were standard body weight, 41.0% of subjects were overweight and when subjects needed orthodontics, 52.7% of subjects were standard body weight, 33.8% of subjects were low-weight, and 13.5% of subjects were overweight(p<0.001). In the correlation between oral condition and BMI, DT index showed negative interrelation with FT index(r=-0.179) and positive interrelation with periodontal condition(r=0.221), MT index showed positive interrelation with occlusion(r=0.137) and FT index showed positive interrelation with height(r=0.136). BMI showed highly positive interrelation with weight(r=0.940), and when occlusion was worse, it shows negative interrelation with BMI(r=-0.293). Height showed highly positive interrelation with weight(r=0.447), and when the more subjects had malocclusion, it showed low negative interrelation with weight (r=-0.257). Conclusions : It was considered that an adolescent period forms health habits, so it was important to increase health action through education for growing healthy adult and not only guiding improvement of dietary life for keeping normal weight, but also conducting oral health education for treating regular occlusion of oral condition and prosthetic procedures for loosing tooth right time.

Quality management is a recent phenomenon. Advanced civilizations that supported the arts and crafts allowed clients to choose goods meeting higher quality standards than normal goods. There are many methods for quality improvement. Health care, refers to the treatment and management of illness, and the preservation of health through services offered by the medical, dental, complementary and alternative medicine, pharmaceutical, clinical laboratory sciences (in vitro diagnostics), nursing, and allied health professions. Health care embraces all the goods and services designed to promote health, including "preventive, curative and palliative interventions, whether directed to individuals or to populations. The overall impact of managed care remains widely debated. Proponents argue that it has increased efficiency, improved overall standards, and led to a better understanding of the relationship between costs and quality. Practices can solicit feedback from patients in a variety of ways: phone surveys, written surveys, focus groups or personal interviews. What do I do with the results? While you don't have to act on every suggestion that your patients give you, you should take action on the key items that are causing dissatisfaction.

Objective: The authors have experimented for the artificial plaque removal effect of several kinds of 360 degree rotating head typed tooth-brushes with sonic vibratory actioned by using of automatic machine for horizontal scrub method in order to find the better toothbrush type for plaque removal. Methods: The experiment was conducted on three medium to 360 degree rotating head toothbrushes, a medium sized toothbrush and a medium sized toothbrush, and a flat toothbrush consisting of 30 ordinary toothbrushes. A brushing machine with horizontal scrubbing was manufactured and had variations of the end of the bristle attached to or near the surface of the teeth, a vibrating wave action force of 16,000 or 18,000 cycles per minute, and a working time of 2 or 3 minutes. The tooth removal effect was confirmed by scanning and analyzing images with a computer program after automatic brushing with the machine. The elimination rate results for each group were analyzed using the independent t-test and one-way ANOVA test. Results: It revealed the most in removal effect for the artificial plaque in such conditions as action at near the tooth surface with 18,000 cycle for 3 minutes in case of using A, B, and C tooth-brush. And it has more removal effect rate than for using the plane tooth-brush (p<0.05). Conclusion: It was recommended to develop the 360 degree rotating head and vibratory toothbrush focusing to use near the tooth surface with 18,000 cycles of vibration for 3 minutes at one site of the teeth area.

Tea derived from the leaves and buds of Camellia sinensis (Theaceae) is consumed worldwide. Green tea contains various components with specific health-promoting effects, and is believed to exert protective effects against diseases including cancer, diabetes and hepatitis, as well as obesity. Of the various tea components, the polyphenol catechins have been the subject of extensive investigation and among the catechins, (-)-epigallocatechin gallate has the strongest bioactivity in most cases. Our research group has postulated that hepatocyte nuclear factor-$4{\alpha}$, sterol regulatory element-binding proteins, and tumor necrosis factor-${\alpha}$ are targets of green tea constituents including (-)-epigallocatechin gallate for their anti-diabetes, anti-obesity, and anti-hepatitis effects, respectively. Published papers were reviewed to determine whether the observed changes in these factors can be correlated with anti-cancer effects of green tea. Two major action mechanisms of (-)-epigallocatechin gallate have been proposed; one associated with its anti-oxidative properties and the other with its pro-oxidative activity. When reactive oxygen species are assumed to be involved, our findings that (-)-epigallocatechin gallate downregulated hepatocyte nuclear factor-$4{\alpha}$, sterol regulatory element-binding proteins, and tumor necrosis factor-${\alpha}$ may explain the anti-cancer effect of green tea as well. However, further studies are required to elucidate which determinant directs (-)-epigallocatechin gallate action as an anti-oxidant or a pro-oxidant for favorable activity.

Purpose: The aim of this work was to investigate the beneficial effects of rhamnazin against inflammation, reactive oxygen species (ROS)/reactive nitrogen species (RNS), and anti-oxidative activity in murine macrophage RAW264.7 cells. Methods: To examine the beneficial properties of rhamnazin on inflammation, ROS/ RNS, and anti-oxidative activity in the murine macrophage RAW264.7 cell model, several key markers, including COX and 5-LO activities, $NO^{\cdot}$, $ONOO^-$, total reactive species formation, lipid peroxidation, $^{\cdot}O_2$ levels, and catalase activity were estimated. Results: Results show that rhamnazin was protective against LPS-induced cytotoxicity in macrophage cells. The underlying action of rhamnazin might be through modulation of ROS/RNS and anti-oxidative activity through regulation of total reactive species production, lipid peroxidation, catalase activity, and $^{\cdot}O_2$, $NO^{\cdot}$, and $ONOO^{\cdot}$ levels. In addition, rhamnazin down-regulated the activities of pro-inflammatory COX and 5-LO. Conclusion: The plausible action by which rhamnazin renders its protective effects in macrophage cells is likely due to its capability to regulate LPS-induced inflammation, ROS/ RNS, and anti-oxidative activity.

The purpose of this study was to examine how dental-care institutions responded to discontented customers and how much they provided grievance service and tried not to displease customers. After a survey was conducted on dental-care institutions from January 20 through February 20, 2007, the answer sheets from 206 respondents were analyzed with SPSS WIN 12.0 program, except four incomplete ones. The findings of the study were as follows: 1. 32.5 percent of the respondents were aware of grievance service, and 64.6 percent actually provided no grievance service. 94.7 percent had ever met customers who made a complaint. 2. The most common grievance of medical consumers was that it took long time to receive treatment and to wait for it. The second most dominant complaint was that the treatment they received was beyond the coverage of health-care insurance(30.6%). An insufficient medical explanation was the third most common grievance(6.3%), followed by excessive medical bills(5.8%). The most dominant number of monthly grievance case was one to ten(91.3%). As for how customers voiced their complaints, the largest number of customers talked employees about that in person(88.2%), and dental hygienists were mainly identified as a person who handled their grievance(56.8%). Concerning how the dental-care institutions responded to complaining customers, the largest number of the institutions took an immediate action(34.5%), and the second largest group took a measure after investigating the disposition of discontented patients(30.0%). The third greatest group just made an excuse(11.1%), and the fourth greatest group directed active efforts into taking care of complaining customers by offering grievance service (7.0%). 3. The dental-care institutions got a mean of 3.02 in grievance handling. The institutions that dental hygienists were in charge of grievance handling statistically significantly better responded to discontented customers than the others that receptionists were in charge of that(p < .01). The institutions that had no monthly grievance cases took care of discontented customers statistically significantly better than the institutions that faced one to ten grievance cases or 11 or more cases (p < .05). 4. The dental-care institutions got a mean of 2.59 in providing service of preventing customers from being dissatisfied. The institutions located in Seoul, Incheon and Gyeonggi province provided statistically significantly better service of that kind than the others located in the other regions(p < .01). And the dental-care institutions that dental hygienists were in charge of grievance handling offered statistically significantly better service of that kind than the dental-care institutions that receptionists were in charge of it(p < .05).

Objectives: The purpose of this study was to apply an effective oral health promotion program and effect for underprivileged lower grade students. This study attempted to resolve some oral health inequality issues by providing underprivileged children with an oral health action program designed to promote positive oral health maintenance habits. Methods: This study was carried from May to August of 2009 with 77(control group 27 subjects, experimental group 36 subjects) elementary school students selected among first to third graders attending regional welfare center's after school program in Seoul. To the control group, conventional education methods were applied. To the experimental group, newly designed program was conducted by three project experts(1 expert, 1 dentist, 1 dental hygienist). It consisted of 5 sessions and progressed with various activities. It was focused on achieving target knowledge and changing oral health behavior. In order to evaluate the designed educational program, learners' achievement was evaluated with implementing the questionnaire and one-on-one interviews. And also the oral health improvement was evaluated based on change of Patient Hygiene Performance(PHP) index. Results: Based on the results of learners' achievement, the experimental group showed the significant increment of the oral health knowledge by the relapsed time, and it maintained after finished the program(p<0.001). The patient hygiene performance index showed not significant changed(p>0.05), but 1 month later the control group showed an increment of the PHP score, but the experimental group showed a decrement of it. Conclusions: Oral health promotion program by project approach could give a long-lasting educational effect to the children and encouraged proper oral hygiene behavioral changes.

This study was conducted to analyze the dental care utilization pattern of the city residents. An interview and questionnaire survey was carried for 1008 people who lived in Kimchun-city, Kyungsangpook-do, from february 1 to March 30, 1992. The summarized results are as follows : The rate of persons who experienced the oral disease was 32.7 per 100 persons during 1 year and it was highest in the age group of 20$\sim$29. During 1 year period, 90.3% of the cases had treated the perceived oral disease, 9.7% had done no action. 65.8% had treated experienced oral disease at dental clinics. The rate of person who dad experienced dental prosthesis during ten-year period was 37.5% among 18year and older, and it was higher in male as compared to female and it was highest in age group of 40$\sim$64 year old. The rate of person who had treated dental prosthetics by the unauthorized illegally was 27.0%, and the reason for it was cheap-price free(44.2%). Of the person who dad treated dental prosthetics by the unauthorized illegally, 64.3% had satisfied and 4.3% had done out of use, while each was 80.1%, 2.7% at dental clinics. The rate of persons with missing teeth was 18.0%. Of the persons with missing teeth, 57.6% did not treat the missing teeth due to economic reason and 89.6% hopped treating the dental prosthetics at dental clinics. In consideration of above finding, we may conclude that oral health community program to prevent oral diseases should be intensified, oral health education to raise oral health knowledge should be performed periodically and the control of unlicensed activities should be enforce at community health center and allows benefits for prosthetics.
