구강위생을 위한 간편성과 편리성 때문에 영유아에서 건강취약자 및 일반인에 이르기까지 구강청결티슈 사용이 증가되고 있다. 또한 기본 성분인 정제수 외에도 구강위생에 도움이 될 목적으로 다양한 기능 성분이 첨가된 구강청결티슈들이 시판되고 있다. 하지만 함유 성분에 대한 제공정보가 부족하고 함유량 기준이 마련되지 못하고 있어 구강 환경이 예민한 영유아 등에게 적용하기 위해서는 이들 제품에 대한 연구자료가 필요할 것으로 보인다. 본 연구에서는 구매도가 높은 시판 구강청결티슈 5종에 대한 구강세포 안전성을 확인함으로써 제품사용 시 유의해야 할 정보를 제공하고자 하였다. 시험 결과 피셔프라이스와 닥터케네디 제품 성분은 구강미생물 S. mutans 및 A. actinomycetemcomitans에 대한 항균작용을 나타냈지만 구강상피세포 및 구강섬유세포에도 독성을 나타냈다. 항균작용이 제한적인 궁중비책, 마이비, 아이수 제품 성분은 구강상피세포 및 구강섬유세포에 대한 독성도 낮았다. 피셔프라이스와 닥터케네디 제품 성분에 의한 구강세포 독성은 G2/M phase에서 세포주기 진행 억제와 세포자멸 유도에 의한 것으로 분석되었다. 따라서 구강 환경이 예민한 영유아 등을 대상으로 한 반복적이고 빈번한 사용은 구강세포 독성의 가능성을 높일 수 있다.

Objectives: This study aimed to investigate the current status of oral health applications developed for smartphones because they can be used as a new educational medium to manage and improve oral health. Methods: This study examined 60 basic oral health applications provided by Google Play Store and Apple App Store as of May 2019 and examined delivery contents, delivery methods, application types, and other information. Results: Apple included 65.4% of oral apps in the game category whereas Android included 64.3% in the education category (p>0.05). All Apple's apps and 71.4% of Android apps were developed overseas (p<0.01). The delivery contents were 61.5% for Brushing + tooth decay in Apple, and 78.6% for others (oral care products and gum diseases) in Android (p>0.05). For the delivery method, game + video was 65.4% in Apple, and game and other methods (text, image, augmented reality) was 42.9% in Android (p>0.05). In the case of application type, play type was the most common with 88.5% in Apple, and 46.4% play type and 39.3% other type (text, appreciation, problem-solving types) in Android (p<0.01). In addition, play type was high in both education (53.8%) and game (90.0%) categories (p>0.05). The average review score was 4.30 in the education category, 4.34 in the case of brushing and care (delivery contents), 4.37 in the case of using game + video (delivery methods), and 4.57 in the case of Play + other types (application type) (p>0.05). Conclusions: The use of healthcare apps is expected to increase owing to improved lifestyles, an increase in the elderly population, cost-effectiveness, and convenience that is not affected by time and place. Effective use of oral health apps will require the participation of dental professionals in the development process to identify the exact status, expand subjects, and provide appropriate information.

Objectives: The purpose of this study is to analyze relationship between oral health status and subjective oral malodor awareness of public health students. Furthermore, this study aimed to recognize the importance of prevention and treatment of internal and external factors and to contribute to the correct oral health management behavior. Methods: The study subjects were 500 students from 5 health departments of 2 universities located in Jeollanamdo who participated in self-administered survey from September 1 to 15, 2014. For statistical analysis, SPSS 21.0 for Windows was used. Descriptive analysis and a Chi-square test were conducted to investigate the effects of general characteristics, health behavior, oral health behavior, and oral health status on subjective oral malodor awareness. Finally, to investigate the relationship between oral health status and subjective oral malodor awareness logistic regression analysis was performed. Results: Subjective oral malodor awareness was significantly higher in the group requiring dental care with the score of 1.63 (95% CI 1.00-2.65) compared to the group not requiring dental care. Subjective oral malodor awareness was significantly higher in the severe coated tongue group with the score of 5.31 (95% CI 1.45-19.40) and significantly higher in the moderate coated tongue group with the score of 2.56 (95% CI 1.61-4.08). Subjective oral malodor awareness was significantly higher in the often mouth breathing group with the score of 2.13 (95% CI 1.02-4.47) and significantly higher in the sometimes mouth breathing group with the score of 2.66 (95% CI 1.65-4.29). Conclusions: In order to prevent oral malodor, it is emphasized that regular dental checkups, proper brushing after the meal, and brushing of the tongue are necessary to remove the coated tongue. In addition, the use of supplementary oral care products is considered to be a meaningful oral health behavior.

Objectives: This study was conducted to evaluate the oral health literacy of foreign students in Korea regarding their utilization of dental clinic services and oral care products. Methods: This study measured the oral health literacy through a self-administered questionnaire that were distributed among 145 foreign students in Seoul and 153 Korean students in Wonju, Gangwon province. The questionnaire is used to assess the oral health literacy with a total of 92 questions including 30 questions on linguistic oral health literacy, and 40 questions on functional oral health literacy (sentence translation ability 27 questions, document decoding ability 13 questions), and 22 questions on the general characteristics. The collected data were analyzed by frequency test, ${\chi}^2$, independent t-test, and ANOVA with p-value of <0.05 was considered statistically significant. Results: The linguistic oral health literacy awareness score was doubly lower in foreign students $20.5{\pm}22.4%$ than Korean students $53.9{\pm}18.4%$ (p<0.05), three words were not statistically significant with less than 10% of all the foreign and Korean students. Correct answer rate of sentence translation ability was statistically significant in all questions by foreign students $26.7{\pm}27.1%$ and Korean students $99.0{\pm}2.3%$ (p<0.05). Correct answer rate of document decoding ability showed a relatively small difference between foreign students and Korean students with $54.7{\pm}33.1%$ and $87.3{\pm}8.7%$, respectively, but it was statistically significant in all questions (p<0.05). Oral health literacy according to residence period and Korean language class level of foreign students were the most correlated among the other variables (p<0.05). Conclusions: Dental terminology was difficult for ordinary people to understand regardless of the Korean language proficiency levels, so it is recommended and needed to express dental clinical terms in simple layman's term or to use illustrations to dental patients. In case of foreign residents in Korea, interpretation services are needed. Additionally, labels and instructions of oral hygiene products retailed in Korea with the consideration for foreigners are required.

The present study attempts to investigate the knowledge, belief, attitude and behavior of healthcare major students and non-healthcare counterparts concerning their oral hygiene. The purpose is to provide basic data for positive oral health activities to the students with non-healthcare major, who tend to have insufficient information on oral hygiene. A survey was conducted to 400 students in K college in Incheon from May 1-30, 2003. A total of 384 surveys were analyzed using the SPSS program Version 10.0. The result is as follows: 1. There was a statistically significant difference in the knowledge on oral hygiene between the healthcare(M=3.08) and non-healthcare(M=2.78) students(pE0.05). 2. As for the beliefs and attitudes toward oral health behaviors, 56.9% of the healthcare students and 60.6% of non-health care counterparts responded "moderate" to the question asking if they liked tooth-brushing. The reason they liked tooth-brushing were cleanliness(60.3% of healthcare and 71.9% of non-healthcare students). They didn't like brushing their teeth because they felt it was a nuisance(60.6% of healthcare and 54.5% of non-healthcare students). 90.6% of healthcare students and 90.1% of their non-healthcare counterparts said they wanted to keep their oral health intact. Most of the subjects seemed to acquire information on oral hygiene through mass media(62.2% of healthcare and 55.3% of non-healthcare students). The persons who give them oral health information are their friends or neighbors(26.8% of healthcare and 22.8% of non-healthcare students), and dental hygienists were the last in the list of the sources of information(3.4% of healthcare and 2.5% of non-healthcare students). 3. Their oral health behaviors were also considered, 64.4% of the healthcare students and 53.7% of the non-healthcare counterparts brush their teeth once or twice a day, 51.4% of the former brush their teeth for 2 minutes and 44.8% of the latter for 3 minutes. Some of them use oral health measures other than tooth-brushing(13.3% of healthcare and 14.3% of non-healthcare students). Not many of them used oral health products(6.6% of healthcare and 5.9% of non-healthcare), and the difference was statistically significant(pE0.05). The largest number of healthcare students brush their teeth right before going to bed(29.9%), while their counterparts do it after breakfast(25.8%)

Objectives: The purpose of this study was to determine the importance of oral health care in the control of diabetes mellitus. Methods: The raw data of the National Health and Nutrition Examination Survey were utilized and 4,445 adults aged 19 and over were surveyed and examined. Complex samples crosstabs and general linear model analysis were carried out. Results: In total, 69.6 percent of the subjects were normal, 21.4 percent had impaired fasting glucose, and 9.0 percent had diabetes. By sex, 25.8 percent of the men had impaired fasting glucose and 10.8 percent had diabetes. Women with impaired fasting glucose accounted for 17.2 percent and 7.2 percent of women had diabetes. Impaired fasting glucose and diabetes were more common among men. Fasting glucose values were higher in the respondents who were male, were younger, whose monthly mean household income was lower, and who were less educated. Fasting glucose values were higher when the frequency of toothbrushing was lower and when dental floss and a dental brush were not in use. Fasting glucose was lower when there was no periodontal disease, when there was less difficulty in mastication, and when there were no implants in the upper and lower jaws. Conclusions: Oral health care workers should develop a variety of programs to motivate patients to take care of their own oral health actively and responsibly.
