The purpose of this study was to investigate the perception of calculus removal, an essential factor in periodontal disease in the elderly population. Further, the study aimed to identify the oral hygiene management matters of individuals and to use the information as primary data for preventing dental loss and improving the prevention of chronic diseases. From December 20, 2019, to January 15, 2020, the results of 171 studies on oral hygiene management and awareness of calculus removal among the elderly aged 65 or older in Busan and Gyeongnam are as follows: The elderly with good health appreciated their functional oral health status and showed significant differences (Χ²=298.26, p<.001). Many of the elderly brushing their teeth at least three times a day had a better health status and showed significant differences according to their health status (= 134.42, p <.001). Usually, older people who are in good health have a dental floss (Χ²=89.31, p<.001), and the dental floss were used more often and significantly differed depending o health status (Χ²=92.53, p<.001). The elderly's perception of tartar removal has shown that the overall average out of five points is positive at 3.48. Older female adults were more positive and showed significant differences regarding gender (t=-7.95, p<.001). Senior citizens aged 65 to 70 were more positive about dental removal than those aged 71 or older, with significant differences in age (t=6.65, p<.001). As described above, oral hygiene management for the elderly population needs to develop a periodontal disease prevention program linked to systemic diseases, considering that there are many chronic diseases.

Objectives: The purpose of the study is to investigate the cognition of dental caries prevention by the level of socioeconomic status based on Gallup survey in Korea. Methods: This study was done by Korean Gallup survey in October, 2010. A trained researcher carried out the computer aided telephone interview(CATI) using a structured questionnaire. This study was based on the latest population statistics of resident registration and whole country's phone data base. This survey included 869 selected Korean adults over 19 years old, and they were asked to answer a CATI. The questionnaire consisted of general characteristics of the subjects and socioeconomic factors including age, gender, education level, monthly income, and residential area. Cognition of dental caries prevention was measured by Likert 4 scale including 'much', 'a little', 'rarely', and 'never'. The attitude toward dental caries prevention consisted of daily tooth brushing frequency, experience of oral health education, regular dental checkup, chewing gums(xylitol), regular scaling, and use of oral care devices. Data were analyzed using SPSS 20.0 for frequency analysis, t-test, chi-square test, and one way ANOVA. Cronbach's alpha was 0.462 in oral health concern and attitude. Results: Mean of the frequencies of daily tooth brushing in men was 2.54 times and 2.78 in women. By the comparison to age group, 35-44 years old group had 2.82 times, 19-37 years old group had 2.72 times, and 45-64 years old group had 2.51 times. The level of education and monthly income was proportional to the tooth brushing frequency. Highly educated and higher monthly income group received regular dental checkup within a year and used the auxiliary oral health care devices.

Objectives: The purpose of this study was to determine if self-rated oral health differed according to self-reported oral health behaviors in Korean adolescents. Methods: The raw data of 'The 6th Youth Health Behavior Online Survey' carried out by the Korea Center for Disease Control and Prevention were analysed. Independent t-test, one-way ANOVA, and Logistic regression analysis were used to assess the relationships between oral health behaviors and self-rated oral health (n=73,238). Results:Oral health behaviors had stronger influence on daily toothbrushing habits. In particular, participants who brushed their teeth in the morning and participants who brushed their teeth more than 3 times a day were more likely to have good self-rated oral (P<0.001). Conclusions: Korean adolescents with high self-rated oral health reported practicing good oral health behaviors. These results highlight the need for the further practicable oral health education programs.

Background: Human papillomaviruses (HPV) may play an important role as one of the possible etiologies of oral squamous cell carcinoma (OSCC). The present study aimed to investigate the association between HPV and OSCC in young Japanese patients by examining the presence of HPV DNA and surrogate markers in OSCC tissues. Materials and Methods: Forty young patients with OSCC whose surgical specimens were available were analyzed and compared with 40 patients randomly recruited from a pool of patients aged >40 years. HPV DNA was detected using the polymerase chain reaction-based AMPLICOR$^{(R)}$ HPV test, and surrogate markers of HPV infection were analyzed using immunohistochemical techniques to detect $p16^{INK4a}$ and p53. Results: Only two (5%) young patients and one (2.5%) older patient were positive for HPV DNA. $p16^{INK4a}$ overexpression was identified in six (15%) young patients. p53 staining levels were not high in tissues of most young patients (27 patients, 67.5%). HPV DNA status did not significantly correlate with $p16^{INK4a}$ expression levels. Profiles of increased levels of $p16^{INK4a}$ expression with diminished levels of p53 staining were not associated with the presence of HPV DNA. The combined p53 with $p16^{INK4a}$ profiles were significantly correlated with alcohol consumption in younger patients (p=0.006). Conclusions: Results of the present study indicate that HPV is less likely to cause OSCC in young Japanese patients, and the $p16^{INK4a}$ expression level is not an appropriate surrogate marker for HPV infection in OSCC.

Background: Smartphones are a modern necessity. While they are convenient to use, smartphones also have side effects such as addiction. This study assessed the relationship between smartphone use, a part of everyday life in modern society, and oral health. Methods: An analysis was conducted using 2017 Korea Youth Risk Behavior Web-based Survey data. The propensity score estimation algorithm used logistic regression and 1:1 matching algorithm using nearest-neighbor matching. After matching, a total of 15,032 participants were classified into two groups containing 7,516 teenagers each who did and did not use smartphones, respectively. Results: Comparison of oral health behaviors according to smartphone use revealed a statistically significant difference in the frequency of tooth brushing per day, use of oral hygiene products, intake of foods harmful to oral health, and experience of oral health education (p<0.05). The factors affecting oral pain experience of adolescents were examined. Compared to male participants, female participants had an odds ratio of 1.627 for oral pain (p<0.05). According to the household income level, compared to the group with higher income, the group with lower income showed higher oral pain experience (p<0.05). Oral pain experience was 1.601 times more frequent among teenagers using smartphones (p<0.05). Conclusion: The results of this study indicated that use of smartphones by adolescents affected their oral health. These findings indicate the need for improved oral health management through the use of effective school oral health programs and individual counseling by oral health professionals, promotion of information dissemination through public media, and development of prevention strategies.

Oral cancer is a common site of head and neck cancer, and is relatively frequent in Northeast Thailand. The objective of this hospital-based, case-control study was to determine associations with risk factors. A total of 104 oral cancer cases diagnosed between July 2010 and April 2011 in 3 hospitals were matched with control subjects by age, sex and hospital. Data were collected by personal interview. There were significant associations between oral cancer and tobacco smoking (OR=4.47; 95%CI=2.00 to 9.99), alcohol use among women (OR=4.16; 95%CI=1.70 to 10.69), and betel chewing (OR=9.01; 95%CI=3.83 to 21.22), and all three showed dose-response effects. Smoking is rare among Thai women (none of the control women were smokers), but betel chewing, especially among older women, is relatively common. We did not find any association between practicing oral sex and oral cancer.

Background and Aim: Less than 50% of oral cancer cases are diagnosed at early stages of the disease and this is in part due to poor awareness and lack of knowledge on the signs and symptoms of oral cancer. This study sought to measure the baseline awareness of oral cancer in Malaysia and aimed to increase public awareness and knowledge of oral cancer using a mass media campaign. Methods: Baseline awareness and impact of the campaign was measured using self-administered questionnaires sent via email to individuals. The campaign was aired on two national television channels and the reach was monitored through an independent programme monitoring system. Results: 78.2% of respondents had heard of oral cancer, and this increased significantly after the campaign. However, the ability to recognize signs and symptoms remains unchanged. We found that the level of awareness differed between the distinct ethnic subgroups and the reach of the campaign was not uniform across all ethnicities. Conclusion: This substantial study to measure the oral cancer awareness in Malaysia provides important baseline data for the planning of public health policies. Despite encouraging evidence that a mass media campaign could increase the awareness of oral cancer, further research is required to address the acceptability, comprehensiveness and effectiveness. Furthermore, different campaign approaches may be required for specific ethnic groups in a multi-ethnic country such as Malaysia.
