Objectives: The purpose of the study is to investigate the factors associated with gingival bleeding(GB) by tooth brushing in college students. Methods: A self-reported questionnaire was filled out by 232 college students in Daegu Health College from March to June, 2014. Data were analyzed for frequency, chi square test, and logistic regression analysis using SPSS 12.0 program. The study was a cross sectional study. The questionnaire consisted of general characteristics of the subjects(gender, age, marital status, and smoking), frequency and duration of tooth brushing, scaling experience, and physical health status. Self-reporting hemorrhage was reported by yes or no. Frequency of tooth brushing was documented as the number of behavior. Above 4 times of tooth brushing was defined as 4. Duration of tooth brushing was documented as minute. Above 4 minutes, it was recorded as 4. In physical health status, 1 is feeling weak and 4 is feeling very healthy. Cronbach alpha was 0.82 in the study. Results: There were significant relationships between gingival bleeding and age(p<0.05), subjective health(p<0.01), tooth brushing frequency(p<0.05) and duration(p<0.05) by chi square test. Logistic regression analysis showed that the age(p<0.05), subjective health(p<0.01), tooth brushing frequency(p<0.05) and duration(p<0.05) were associated with gingival bleeding. Prevalence of gingival bleeding in 20 years was 0.62(odds ratio 1.85, 95% CI 1.00~3.43) and it was higher than that in 10 years. Prevalence of gingival bleeding in good health group was -1.38 and it was lower than that in poor health group. Conclusions: The factors associated with gingival bleeding were age, subjective health, and tooth brushing frequency and time.

This study aimed to investigate the effect of repeated oral health education on the oral health of preschool children. This study classified the control group of children of 5~6 years of age where the oral health education was conducted one time, and the experiment group where the oral health education was conducted 4 times. The oral health conditions of each group and their risk of developing dental caries were also assessed. No significant difference was observed in the participants in terms of general characteristics, oral health conditions, risk of developing dental caries, and oral health behavior after oral health education. The two groups did not show a significant difference (p<0.001) in dental plaque index before and after oral health education, and showed a significant difference (p<0.001) according to the number of education sessions. Before oral health education, the participants in both groups were brushing their teeth incorrectly. However, after the third session, 56.7% of the participants in the experimental group and 9.4% in the control group used the correct method of tooth brushing. A significant difference was observed between the two groups (p<0.05). In addition, when the tooth-brushing time was compared, the two groups showed a significant difference (p<0.001), and a significant difference was observed in terms of the number of education sessions (p<0.05). In summary, repeated oral health education had significant influences on the dental plaque index, tooth-brushing method, brushing occlusal surfaces, and tooth-brushing time. Therefore, when oral health education is carried out, repeated oral health education in children is more effective than one-time oral health education as reflected in the changes in dental plaque index and oral health behavior. Moreover, oral health education is considered effective in changing the oral health behavior of children when conducted at least 3 times.

The purpose of this study was to provide the basic data for preventing dental caries, and maintaining and enhancing oral health. The subjects of this study were 138 male and female students who were in the 6th grade of elementary schools in Gimpo city. This study investigated the number of decayed tooth and the factors related to the number of decayed tooth, by using the results of questionnaire and oral health survey over such subjects. So, this study obtained the following conclusions. 1. For the number of decayed tooth, 'nothing(D = 0)' was the highest as 37.7%, and 'from two to three' was 23.9%, 'more than four' was 21%, and 'one' was 17.4% in order. 2. For the frequency of visiting dental clinics within the last one year, 'one to two times' was the highest as 52.2%, and the children who have not visited dental clinics even one time during one year were 23.9%. 3. For average daily tooth brushing frequency, 'two times' was the highest as 71.7%. For the use of oral health devices besides toothbrushes, 'I don't use' was the highest as 54.3%. For the experience of sealant and fluoride application, 'nothing' was the highest as 86.9% and 71.3% respectively. For the recognition on the use of fluoride dentifrice, 'I don't know' was the highest as 66.9%. 4. The socio-demographic factors related to the number of decayed tooth were mother's age, mother's background, mother's employment, and after-school fosterer(p > 0.05). 5. The oral health care factors related to the number of decayed tooth were average daily tooth brushing frequency, the use of oral health devices besides toothbrushes, and the experience of fluoride application.(p > 0.05) 6. The snack intake factors related to the number of decayed tooth were tooth care foods intake frequency and decaying foods intake frequency(p > 0.05). 7. The oral health belief item related to the number of decayed tooth was susceptibility(p > 0.05). 8. According to the results of regression analysis, the less mother was employed, the more the average daily tooth brushing frequency was, the more the tooth care foods intake frequency was, the less the decaying foods intake frequency was, and the higher susceptibility was, the lower the number of decayed tooth. 9. In order to prevent and cure early the dental caries which occur frequently in elementary school students, the establishment of oral health centers within schools should be expanded to promote tooth brushing instruction, fluoride solution rinsing, diet control, periodic oral examination.

This study conducted a 'specialist tooth brushing' method against the severely disabled once every other week. The purpose of this study is to analyze and validate the effectiveness of maintaining healthy periodontal management when consistent oral hygiene lasts with minimum stimuli for 24 - months. The conclusions were as follows. Table 2 compares the difference between group 1 and 2 from the 1^st to 11th management and verifies the actual difference in measurement of each index. Group 1 used a professional tooth brush while Group 2 used a general brush. There were found many significant differences in dental index. As for PHP, Oral Malodor index and gingival bleeding, it was found that one or two times of dental care can make substantial differences in dental health condition. These results show that as the number of toothbrush method has been increased, gingival bleeding and periodontal index are significantly improved, not to mention the improvement of gingivitis and periodontal disease. This is because periodontal tissue is affected by brushing method, brushing time and consistency of dental care. During the 6-month period, 20 minutes of active periodontal care was intensively conducted, and for 18-months the effect of consistent care was verified by 10-minute periodontal care once every other week. As a result of the test, it was found that there was no complete regression in the basic periodontal treatment and the periodontal health condition had been maintained for 24 months. Also this test shows that, despite of inconsistent dental hygienic care, regular plague control can prevent dental diseases and maintain the dental health. This study proved that periodontal condition can be maintained by periodontal care once every other week as the tooth brushing properly stimulates the gums with positive effect. Therefore, professional dental healthcareworkers should be designated for each facility for the disabled, and dental health of the disabled should be professionally cared on a regular basis, and consistent and repetitive management by the dental care specialist are required.

Background: The size of the tooth whitening market and toothpaste market is increasing worldwide. The purpose of this in vitro study is to confirm and compare the coffee stain removal effects of commercial whitening toothpaste in sound and demineralized teeth, respectively. Methods: A total of 112 flat permanent bovine teeth specimens were manufactured. Half of the surface of the specimen was coated with an acid-resistant varnish and deposited in an artificial demineralizing solution for 65 hours. The varnish applied to half of the specimen was removed and deposited in a coffee solution for 96 hours to induce coloring. Two control and five experimental group toothpastes for teeth whitening were selected and the main components were investigated. Toothbrushing was performed 50, 100, and 150 times for each toothpaste group. A total of four images were obtained: before the start and after 50, 100, and 150 times of brushing to obtain the lightness (L^*) values of the sound and the demineralized tooth surfaces. The difference in the average value between toothpaste groups at each treatment period was analyzed by one-way ANOVA. The difference in the L^* average value according to the number of the brushing was analyzed by repeated measure ANOVA. Results: All toothpastes in the seven groups contained abrasive agents and had different ingredients for each product. Compared to before brushing, the L^* value changed significantly in all toothpaste groups after brushing 50 times (p<0.05). This was common in both the sound and demineralized teeth surfaces. Demineralized teeth had significantly lower L^* values at all brushing times than that in sound teeth (p<0.05). Conclusion: The effect of whitening teeth was different for each toothpaste. Demineralized teeth were more likely to cause coloration than sound teeth, and the coloration was not removed well.

Objectives : The purpose of the study is to investigate the oral health behaviors between students studying in Vancouver, Canada and college students in Daejeon, Korea. Methods : A self-reported questionnaire was filled out by 239 students in November, 2013. The questionnaire consisted of oral health behavior including tooth brushing methods between two countries. Chi-square test and t-test were analyzed. The analyses were conducted using R version 2.14.2(R Foundation for statistical Computing, Vienna, Austria). Results : The number of tooth brushing in Korean students was higher than those in Canada. Fifty nine percent of the Koreans brushed their teeth 3 times a day while 62.3% of students in Canada brushed their teeth 2 times a day(p<0.0001). Those who were taught on oral health education tended to brush the teeth more frequently that those who had not. Koreans and Japanese tended to brush teeth more frequently after breakfast than the Taiwanese(p=0.005). Koreans also brushed teeth after dinner more frequently than Japanese, Taiwanese, and other foreigners(p=0.012). Conclusions : This study indicated that Koreans have better oral health behaviors in comparison to students studying abroad.

Purpose : This study was conducted to improve cognitive oral healthcare care by analyzing the correlation between oral health behavior and oral health status Korean adolescents. The subjects were 65,528 youths in 798 schools monitored in the Twelfth Korea Youth Risk Behavior Web-based Survey in 2016. Methods : The general characteristics consisted of 9 items including sex, grade, and academic performance. The academic performance and economic status were restructured into "upper, middle, lower". Subjective health perception and subjective oral health perception were reorganized as "health", "normal", "no health". The sub-areas of oral health behavior include five times of daily brushing during the day yesterday. The number of brushing times was "0", "1-2", "3", "more than 4" After lunch at school, brushing was restructured as "always," "sometimes," "not." The oral health status subscale consisted of 6 items including tooth breakage and toothache at the time of eating. Result : Tooth fracture(43.7 %), pain in mastication(43.7 %), tooth tingling(47.4 %), gum pain and bleeding(45 %), pain in buccal mucosa(43.8 %) and halitosis(46.6 %) were rare in adolescent having healthy oral health status cognitively(P<.001). Nosymptom adolescents without dental sealant showed low tooth fracture(0.64 times), pain in mastication(0.67 times), tooth tingling(0.59 times), gum pain and bleeding(0.84 times), pain in buccal mucosa(0.76 times), and halitosis(0.90 times). Nosymptom adolescents without scaling showed low tooth fracture(0.88 times), pain in mastication(1.03 times), tooth tingling(0.82 times), gum pain and bleeding(0.64 times), pain in buccal mucosa(0.70 times) and halitosis(0.82 times). Conclusion : This study revealed that oral health status is correlated with oral health behavior. Development of educational media and program, and aggressive promotion required to establish oral health Korean adolescent.

This study was undertaken to verify various relations between dental health belief and related behaviors in mothers and children. Data for this study were obtained by 264 pairs of 1st and 3rd grade elementary school children and their mothers by self developed questionnaire, The questionnaires are made on the general socio-economical characteristics, the oral health knowledge and the behaviors relative to the oral health and oral health education as to how mothers implement the oral health related activities for their children, while for the children, the questionnaires have been measured relative to the oral health beliefs and health behaviors for the children. The obtained results have shown that mothers become with more ages, the usefulness to prevent children's oral diseases becomes lower, and as much as mothers have higher education level, the sensitivity relative to the oral diseases has been measured low. To the degree that the students live well in economical respect, it has been found that they placed more importance on the oral health. As much as the number of mothers tooth brushing becomes made more in a day, the tooth brushing of the children becomes more that much, and also has higher level of oral health beliefs. The number of children to see dentists has been found high, and to the extent of increasing frequency of visiting dental clinics. As the number of mothers tooth brushing education becomes made more frequent for the children. Also, as mothers put more restriction on the sugar intakes by the children, they placed higher importance on the oral health for their children. In conclusion oral health behavior in mothers' influence on dental health belief of their children, it has been reviewed necessary to activate more the mother-children joint oral health education and oral health projects that mothers and children take part together, as well as to study more in accurate and systematic approaches through more comprehensive and various subjects and elements further in the future.
