The ABO blood group has been recently proposed to influence development of oral cancer. The aim ofthis study was to evaluate the association between the type of ABO blood group and oral cancer. In a case-control study, 104 patients with oral cancer were compared with 90 blood donors without cancer as controls. Data regarding the patient demographics, blood groups, Rh status, cancer characteristics and oral habits were also compared between two subgroups of squamous and non-squamous oral cancers. For statistical analysis, Chi-square test, t-student Test and Logistic Regression were used to analyze the relationship between ABO blood groups and oral cancer. The frequency of blood group B was significantly higher in oral cancer patients than controls (32% vs 13%) (p value=0.01), but Rh factor did not show significant difference between cases and controls. According to Logistic Regression, people with blood group B and those older than 50 had 3.5 and 19.4 times elevated risk of developing oral cancer, respectively. The frequency of squamous cell cancer was also significantly higher in men and people older than 50. On the other hand, females, people under 50, and those with blood group B were at 5.6, 2.9 and 4.3 times higher risk of developing non-squamous cell oral cancer,respectively. People with blood group B are at a greater risk of developing oral cancer, and female patients under 50 years of age with blood group B have the highest risk to develop non-squamous cell oral cancer.

Objectives : The aim of the trial was to study the effect of plaque control(tooth brushing instruction) for oral health improvement on periodontitis patients. Methods : 30 patients(35~65 years) with advanced periodontal disease were subjected to a baseline examination including assessment of oral hygiene status(O'leary index), gingival condition(bleeding). the assessment were repeated after 2, 4, 6 weeks. cognitive, behavioral and clinical outcomes were assessed in the primary care setting by questionnaire and clinical oral examination. Results : The oral hygiene status expressed as the individual mean percentage of tooth surfaces with plaque 59.3% at baseline and 21.2% after 6 weeks(p<0.001). The gingival bleeding status expressed as the individual mean point of interdental papilla 3.8 at baseline and 1.9 after 6 weeks(p<0.001). Also, the patients self-assessment about correct tooth brushing behavior was 3.9(5-point likert scales), satisfaction of plan practices 4.1(5-point likert scales), efficacy of tooth brushing instruction 8.7(10-point likert scales). Patients wanted to continuous participation. Conclusions : A verification of effect after individualized oral health instruction and repeated dental plaque control represented to significance on plaque control score, oral care practice and oral health recognition. The important oral care step against periodontal disease is to establish good oral health habits. Also, oral health behavior recognition is more important for the practice of oral health. Therefore professional plaque control and tooth brushing instruction absolutely need in improving oral health.

Oral tongue squamous cell carcinoma (OTSCC) is the most common oral cancer subtype with a maximum propensity for regional spread. Our objective was to study if p53 expression might have any correlation with aggressive patterns of invasion within oral tongue cancers as well as with the histologically identified degree of oral tongue dysplasia. p53 immunoexpression was studied using immunohistochemistry in early staged OTSCCs (n=155), oral tongue dysplasias, (n=29) and oral tongue normal specimens (n=10) and evaluated for correlations with histological and clinicopathological parameters. Our study (n=194) showed a pattern of p53 expression increasing with different grades of tongue dysplasia to different grades of invasive OTSCC (p=0.000). Among the OTSCC tumours, positive p53 expression was seen in 43.2% (67/155) and a higher p53 labelling index was significantly associated with increased Bryne's grade of the tumour invasive front (p=0.039) and increased tumour depth (p=0.018). Among the OTSCC patients with tobacco habits, (n=91), a higher p53 labelling index was significantly associated with increased risk of local recurrence (p=0.025) and with lymphovascular space involvement (p=0.014). Evaluation of p53 through varying degrees of dysplasia to oral tongue cancer indicates that p53 expression is linked to aggressive features of oral tongue cancers and tongue precancers entailing a closer monitoring in positive cases. Among the OTSCCs, p53 expression is associated with tumour aggressiveness correlating with increased grading of invasive tumour front and tumour depth.

Objectives: This study aimed to analyze the textbook content, specifically that of the oral health units, of Korean elementary health textbooks in order to discuss oral health education in elementary schools through textbooks. Methods: The study analyzed the "oral health" units of six health textbooks for students in the fifth and sixth grades of elementary school in Korea. It identified the number of pictures, practice contents, and summaries in the textbooks, calculating the proportion of oral health units relative to the total number of pages in the textbook and comparing the learning goals provided by the WHO with the education contents. In addition, the study also analyzed several keywords from the textbooks in terms of whether they relate to oral health. Results: The comprehensive analysis on the oral health units within the three health textbooks analyzed revealed that all three were similar, except that the textbook from publisher A did not include an introduction. The three textbooks also had differences in terms of the organization of the contents. In terms of the learning goals of the oral health units, there were differences between the WHO standards and the learning goals from the textbooks, with the WHO standards only partially reflected. The analysis also showed that there were more keywords on oral diseases than those related to oral health management and prevention. Conclusions: Improvements should be made regarding the learning goals and education topics of health education in order to ensure that children receive a more systematic oral health education in their earlier years, which will help to develop and correct oral health management habits among elementary school students.

Objectives: The purpose of this study was to determine the importance of brushing before sleeping by comparing the use of oral care products, frequency of dental clinic visits, and oral conditions between individuals who brush and do not brush their teeth before sleeping using data from the 5th and 6th Korean National Health and Nutrition Survey (KNHANES). Methods: Statistical analysis was performed using SPSS 21.0 on data files obtained according to a complex sampling design, and a significance level of <0.05 was set. General characteristics of the participants and year were analyzed using chi-square analysis. Data on the oral conditions, use of oral care products, and frequency of dental clinic visits were analyzed using logistic regression and linear regression. Results: Individuals who brushed their teeth before sleeping showed greater use of oral care products and more frequent dental clinic visits, oral examinations, preventive treatment, and treatment for simple caries (p<0.05) than individuals who did not. Individuals who did not brush their teeth before sleeping showed higher prevalence of permanent teeth caries and periodontal disease, as well as chewing and speaking problems (p<0.05), than those who bushed before sleeping. Conclusions: Individuals who do not brush before sleeping exhibit poorer oral health and lower use of oral care products and frequency of recent dental treatment than those who brush before sleeping. Therefore, it is necessary to alter the government's active policy and improve education about the importance of brushing before sleeping to improve oral health.

Objectives : This study was performed to investigate the recognition of the educators in preschool education institutions on children's oral health promotion. Methods : The subjects of this study included 918 preschool teachers who have been performing an oral health education program for children at preschool centers in Seoul. For this study, the survey was conducted from September 2008 to November 2008 through a questionnaire. Results : It has been found that 58.5% of the given preschool institutions have implemented an oral health promotion program and 99.1% of the respondents recognized the importance of the oral health. 53.9% of the respondents used sweets as a reward for good deeds. Regarding the behaviors of oral health promotion, the daily tooth-brushing and the implementation of a regular oral check-up accounted for 69.0% and 59.5% respectively. The subjects recognized that they have responsibility for the tooth-brushing instruction(91.6%) and provision of an oral inspection(78.3%). It has been also found that the case of performing the oral health program with older age and higher work experiences was significantly high(p<0.05). Conclusions : The recognition and performance of kindergarten teachers on children's oral health affects daily life and healthful living habits of children. Therefore oral health education program for the teachers has to be developed.
