Journal of dental hygiene science, volume 12, issue 2, 2012, Pages 79~84
The purpose of this study was to utilize it as useful basic data for improving oral health and for developing educational guidelines, by surveying the intake frequency in cariogenic food and the dietary intake status in detergent food through dietary life diary of some female undergraduates, and by researching into relationship between dietary intake factor and dental caries. It allowed dietary life diary for 5 days to be recorded targeting female undergraduates for the Dept. of Dental Hygiene, selected dietary life diary of 66 people without omission of record, and used it in this study. The following conclusions were obtained. 1. As a result of surveying the food intake status, it was indicated to be 12.82 for cariogenic food intake frequency, 256.36 for caries incidence available time and 8.32 for detergent food intake frequency. 2. As a result of surveying in order to examine relationship between cariogenic food intake frequency, detergent food intake frequency & cariogenic light-meal intake frequency and dental caries by dividing group with caries and group with non-caries, the group with caries was indicated to be a little higher than the group with non-caries. However, statistically significant difference wasn't indicated. 3. In the correlation between dietary intake status and dental caries, it was indicated that the more rise in cariogenic food intake frequency leads to the more rise in detergent food intake frequency and even in total light-meal intake frequency, but wasn't shown correlation with dental caries. In light of the above results, many limitations were indicated in finding and analyzing the dental caries incidence level and cause just with a method through surveying dietary intake. However, given the more in cariogenic food intake frequency and detergent food intake frequency, the possibility of dental caries incidence could be predicted.

The purpose of this study was to examine the factors influencing the decision to get implant treatment at dental clinic. The subjects in this study were 321 patients at dental hospitals and clinics. Andersen model in which predisposing variables, enabling variables and need variables were suggested as independent variables was used. The implant decision making was selected as a dependent variable in the model. Using logistic regression analysis, we found statistically significant effects of three independent variables: 1) class, 2) satisfaction with the facility; 3) familiarity with others received implant treatment. Those with the middle or high class background were more likely to take implant treatment. Those who were satisfied with clinic facility were more likely to take implant treatment. Those who were familiar with others received implant treatment were more likely to take implant treatment. This result implies the importance of opinion of others were received the same treatment. Hence viral marketing effort is required even in dental care field.

Journal of dental hygiene science, volume 12, issue 2, 2012, Pages 93~102
The purpose of this study was to evaluate the effectiveness of oral health care including some of dental caries activity test on dental clinics of regular visiting on primary school children. The dental surveys and initial caries control and some of dental caries activity test (Alban's, Lactobacillius, S'mutans, un-stimulation saliva test)were performed by trained dental hygienists with dentist from on 6 to 13 years old patients of S dental hospital in Gwangju Metropolitan Cities. The sample size of 39 children (18 in oral health care group, 21 in control group ) and accepted to their parents. The results of caries activity test score(Alban's and Lactobacillius test)were reduced 1.4 to 1.6 times in oral health care group(OHCG). Oral Hygiene Simplified Index of OHCG was reduced 1.6 times during six months and 1 year. DMFT index of OHCG was reduced 1.4 times more than Control Group(CG) after 1 year. DT index of OHCG was reduced 12 times more than Control Group(CG) after 1 year. Dental health capacity of the first perment molar of OHCG was reduced 1.02 times more than CG after 1 year. From the above results, long life related incremental oral health care system has reinforced to primary school children in dental clinic with oral health professional teams.

A study was designed to evaluate the level of moral development in 450 pre-dental professionals of 2 educational institution in Jeollabukdo, Ik san city. Data were collected through self-reported questionnaires from October 2010. The Korean version of the DIT(Defining Issues Test) was adopted to evaluate level of moral development with the score of P(%) and stage. The data were analyzed by descriptive statistics, t-test, one-way ANOVA and Pearson's correlation coefficient. The mean scores of P(%) was 43.10 in dental students and 41.21 in dental hygiene students(p=0.190). The score of stage 5A was highest which was followed by S3, S4, S6, S5B, S2. The score of stage 5B and 6 revealed sigificant difference by groups. The score of stage 6 revealed significant difference by sex in dental students(p=0.003). In dental hygiene students, it's significant difference by religion(S5B, p=0.044), birth order(S2, p=0.027) and growth area(S4, p=0.015). As for the correlations between moral development and the score of the stage, the score of P(%) was negatively correlated with the scores of stage 2, 3, 4 and 5B. On the other hand, the score of P(%) was positively correlated with the scores of stage 5A and 6. In conclusion, for enhancing dental students' moral development it is necessary a systemic ethics education and program development in curriculum.

One hundred seventy four Streptococcus pneumoniae clinical isolates were categorized depending on the types of specimens, the age and the gender, respectively. All isolates were analyzed the characteristics of the multi-drug resistance including levofloxacin antibiotics. In the results of analysis depending on the type of samples, it had been confirmed that sputum was the main source of pneumonia infection because 156 of 174 strains (89.7%) were isolated in sputum samples. The opportunity for isolating the S. pneumoniae that had tolerance to levofloxacin was increased in over 51 age patients group compared with other age and male group. Eight strains of isolates were evaluated higher resistant to levofloxacin, and those also showed multi-drug resistant including penicillin, tetracycline, erythromycin, clindamycin and trimethoprim-sulfamethoxazole. In the results of sequence analysis of quinolone resistance determining region in SP32 (MIC
) and SP96 (MIC
) which were levofloxacin resistant strains, an amino acid substitutions were found Ser-81
Phe in both GyrA of SP32 and SP96, and Ser-11
Gly in only SP96. A Ser-79
Phe substitution of ParC was found in both.

The aim of this study was to investigate the correlations between the self-reported symptoms of periodontal diseases and the quality of life. This study conducted its questionnaire survey over the subjects of 450 adults who had ever visited dental clinics among the adults of age 35-65 living in Seoul and Gyeonggi-do region from January 7 to March 14, 2010. The data were analyzed using a chi-square test, t-test, binominal logistic regression analysis in the SPSS version 12.0 program. Among the self-reported symptoms of periodontal diseases, 65% of respondents perceived that 'I bleed from the gums in brushing my teeth', which was the most, whereas 18.8% of respondents perceived to 'tooth mobility', which was the least. Self-reported symptoms of periodontal diseases was associated with socio-demographic characteristics such as sex, age, level of education and periodic oral examination, dental scaling(p<0.05). People who perceived the symptoms of periodontal diseases experienced functional limitation, physical pain, psychological discomfort, disability in diverse domains, and social handicap more than the group who did not perceive them(p<0.001). OHIP-14 scores were significantly correlated with sex, bleeding gums, swollen gums and bad breath(p<0.05). This study showed the self-reported periodontal problem had a negative impact on the public's leading their happy life. Therefore, in order to enhance the quality of life in adults, it is necessary to prevent periodontal diseases and reduce the subjective symptoms.

The aim of study was to compare the color parameters and mean color difference of porcelain specimens by different veneering technique in order to examine the effect of veneering technique on esthetics of yttria-stabilized tetragonal zirconia polycrystalline(Y-TZP) all ceramic restoration. Three groups of square-shaped core ceramic specimens(14mm in diameter and 0.3, 0.5, 0.7 mm) and two groups of veneering ceramic specimen were prepared for analysis. Color parameter(
) and color difference of zirconia core squares and core-veneer specimens were measured with ShadeEye
spectrophotometer, respectively. Mean color difference(
)were calculated using color difference formula. Two-way analysis of variance(ANOVA) combined with a Tukey multiple-range test were used to analysis the data(
values were not significantly affected by core thickness and veneering porcelain(p=0.083). The color differences(
) of core-veneer specimens with 0.5, 0.7 mm-A1,A2,A3.5 shade were mostly below 3.7 which was within the clinically acceptable range, while color differences between 0.3 mm-A1,A2 showed more than 3.7. All-ceramic system has color characteristics that clinicians have to consider when selecting materials. Also, manufacturers of different porcelain systems must make every effort to achieve color reproducibility.

Journal of dental hygiene science, volume 12, issue 2, 2012, Pages 131~137
The purpose of this study was to examine the sociopsychological stress of dental hygiene students, any possible gaps among them according to their general characteristics and the most influential factor for their stress. The subjects in this study were the dental hygiene students who were selected by convenience sampling from three different colleges. After a survey was conducted for about a month between March and April, 2011, the answer sheets from 561 students were analyzed. As for the sociopsychological stress of the dental hygiene students, economic stress was the heaviest sociopsychological stress that the students suffered(3.17). Regarding differences in each stressor according to general characteristics, they were more stressed out about their economy, families, interpersonal relationships and studies when they had a less conversation with their families. And they had more stress about their economy, families, interpersonal relationships and studies when they found themselves to be more unhealthy. The gaps between them and the others were statistically significant. As a result of analyzing the influential factors for their stress, they had more stress when they had a less conversation with their families(p<0.001) and when they found themselves not to be in good health(p<0.001). It's required to seek ways for dental hygiene students to cope with their stress properly, and the development of stress management programs is necessary. Besides, education and training should be provided for them to regulate their own stress successfully.

Daejeon school-based toothbrushing program using toothbrushing room started at 2007. Ministry of Health and Welfare started national toothbrushing room program without pilot project at 2011. The aim of this study was to provide the basic data to assess of the effect of this program. 59 experimental subjects and 60 control subject were selected after written consent. Oral Examination was done by 1 dentist using WHO standard and Survey of Child Oral Health-Related Quality of Life(COHIP), oral health knowledge and oral health behavior were done using self-registration form. We analyzed the result after adjusting economic status and subjective for the difference between experimental and control groups using SPSS 19.0. The experimental group had lower plaque index, better COHIP and more oral health knowledge significantly(p<0.05). But, The significance was not found in dental caries index and oral health behavior. We suggested the oral health education program and other dental caries prevention program including sealants were needed to prevent dental caries, although school-based toothbrushing program could improve COHIP.

This study aims at investigate dietary behaviors, smoking and drinking status of university students depending on their gender and residential patterns, and analyzing relationships with their subjective health status. The subjects of this study was 538 university students in Metropolitan areas from May 10-31, 2010. Data were analyzed with chi-square test, fisher's exact test, t-test and stepwise multiple regression SPSS 12.0. Male students higher frequency on the intake of eggs, meats and carbonated drinks than female students. The group residing at one's own house showed higher frequency on the intake of beans, fruits and milk than the self-boarding group or other groups(p<0.05), while preferring sweet taste the most. Male students were significantly higher than female students in the amount of smoking and drinking(p<0.05). They had positive recognition on their health conditions as they have higher frequency on the intake of potatoes, seaweeds, green tea and milk with less frequency on the intake of eggs, fast foods and drinking amount. Accordingly, it was considered necessary to have continuous education on nutrition and social supports to prevent their dietary behaviors from leaning on convenience or preference.

Somok, the heart wood of Caesalpinia sappan is used in traditional Chinese medicine. Adherence of S. mutans to the tooth surface can result in the formation of a dental plaque. This study was performed to investigate the antibacterial activity and bacterial adhesion of ethyl acetate extract from C. sappan against S. mutans ATCC 25175. The bacteria were cultured in brain heart infusion(BHI) broth, and then incubated under 5%
for 18~24 hours. The antimicrobial activity of the ethyl acetate extract of C. sappan was then examined using the paper disc methods and MIC. In addition, bacterial adherence to hydroxyapatite was also examined. The ethyl acetate extract was shown to produce inhibitory effects and had MIC values of 125 mg/ml against S. mutans ATCC 25175. The ethyl acetate extract inhibited adhesion of S. mutans to saliva coated-hydroxyapatite beads(S-HA). At 24 hr, the ethyl acetate extract significantly reduced the adherence of S. mutans to S-HA beads relative to the control. The isolated active substance was identified as brazilin(
. Thus, the application of C. sappan can be considered a useful and practical method for the prevention of dental caries.

The purpose of this study was determine the effects of professional tooth cleaning and plaque control instruction(PT & PCI) on reduction of peri-implantitis. A total 80 implant patients were investigated using O'Leary plague index(PI), L
e & Silness gingival index(GI), implant bone loss(BL). While the PT & PCI was conducted by using 'Watanabe method' after scaling for the experimental group, the engine polishing and a plaque control instruction was operated by rolling method after scaling for the control group. The collected data were analyzed with t-test, ANOVA, paired t-test and stepwise multiple regression. PI and GI of the experimental group significantly decreased than the control group(p<0.05). BL, also tended to decreased in the experimental group than the control group(p=0.155). Multiple regression analysis, the factors that was highly correlated with PT & PCI on the PI and GI. According to the implant characteristics, implant location and duration were closely related to PI(p<0.05). Therefore, the PT & PCI is one of the effective methods to reduce the failure caused by the peri-implantitis. Based on this conclusion, that it would be meaningful if the proposed PT & PCI is applied to the oral health management programs of the implant patients.

The aim of this study was to analyze the factors related to whole saliva flow and the xerostomia for the ground use of the materials in developing oral health improvement program and life quality improvement program. So, this study performed a questionnaire survey, targeting at 160 adults, older than 40 years, living in Gyeonggi and Incheon provinces from January to February 2011 and measured unstimulated salivary flow rate and stimulated salivary flow rate. The results are as followings. The group of participants who took gums and candies to relieve oral dryness had low stimulated whole saliva flow. The group of participants who graduated from middle schools, who separated by death, who were not healthy with menopause, and who recognized periodontal disease symptoms and tongue burning sensation recognized more symptoms of dry mouth than others. In addition, the group of participants who were not satisfied with life so much, who couldn't feel the meaning of life, and who recognized negative feelings frequently recognized symptoms of dry mouth more. Women, the group of participants who graduated from middle schools, who suffered from depressive symptoms, and who recognized halitosis had low unstimulated whole saliva flow. The group of participants who graduated from middle schools, who were not satisfied with life so much, who couldn't feel the meaning of life, and who were not satisfied with themselves had low stimulated saliva flow.

Journal of dental hygiene science, volume 12, issue 2, 2012, Pages 181~188
The purpose of this study was to examine effect of locus of control and self-efficacy on stress of selected dental hygiene students. This study provides basic data to develop a method to reduce stress. The students of A women's college in Kyungi province majoring in dental hygiene were asked to answer the locus of control scale, self-efficacy scale, and stress level. As a result, this study concluded the following findings: 1. Locus of control scale was 8.77 and it meant the students used internal control. Self-efficacy scale was beyond median. In stress level category, mean of stress was 2.32, stress with friends was 2.05, stress with money was 2.33, stress with course in life was 2.29, stress with family members was 2.24, stress with study was 2.95. 2. Stress had negative relations with locus of control and self-efficacy. There was a positive relation between locus of control and self-efficacy. 3. Effect of self-efficacy on stress was significantly negative but effect of locus of control on stress was insignificant. In subscale, effect of self-efficacy and locus of control on stress with study was insignificant. 4. Indirect effect of locus of control on stress was statistically significant. The students with internal locus of control showed high self-efficacy and the students with high self-efficacy showed low stress level. In conclusion, educators should make an effort to reduce stress of students and understand the factors related to stress.
