Background: This study aimed to investigate the changes of the amount of P. gingivalis in saliva by professional preventive treatment of periodontal disease by dental hygienists. Methods: A total of 109 subjects participated in this study with informed consent. The control group (38 subjects) performed oral hygiene management individually. The periodontal treatment group (35 subjects) underwent root planning once every 3 weeks for a total of 4 times. The professional periodontal prevention group (36 subjects) underwent interdental cleaning and professional tooth brushing once every 3 weeks for a total of 4 times. Paired T test and analysis of variance were performed to compare the difference among the groups in the amount of P. gingivalis. Results: The copies of P. gingivalis in the professional periodontal prevention group decreased from 773.62±1,198.09 to 241.40±430.40 after treatment significantly. The control group decreased from 525.22±582.54 to 244.29±385.88 after treatment. The periodontal treatment group showed insignificant change of P. gingivalis. Conclusions: This study showed the professional periodontal prevention was more effective than periodontal treatment in decrease of P. gingivalis.

Objectives: The objective of the study was to investigate the factors related to non-use of interdental care products (ICP) in adolescents. Methods: The 2019 Korean Youth Risk Behavior Web-based Survey was used, examining 57,303 subjects. Complex-sample chi-square test and logistic regression analyses were performed to identify differences in ICP according to sociodemographic characteristics and oral health behavior and to determine the factors related to non-use. Results: The ICP non-use rate was 70.9%. Factors related to the non-use of ICP were middle or low economic status (OR=1.367 and 1.677). The other significant variables were less than one tooth brushing per day (OR=1.542), no scaling within 12 months (OR=1.631), and receiving dental treatment either once or two times or more (OR=1.757 and 2.195). Conclusions: To increase the ICP usage rate, continuous attention is needed from schools and families in addition to interventions at the national level.

Objectives: This study aimed to identify factors related to oral health and depression in Korean adults and contribute to the development of a mental health program to improve depression through oral health management. Methods: Data was obtained from the 2021 Korean Community Health Survey. The chi-square test was used to determine the differences in depression experience relative to general participant characteristics and their oral health. To determine the odds ratio and 95% confidence interval, multiple logistic regression analysis was used. All statistical analyses were performed using the SAS software (version 9.4). Results: The results suggest that depression may be influenced by gender, age, household generation, drinking habits, subjective health level, moderate to high exercise, breakfast, high blood pressure, diabetes, subjective oral health level, chewing discomfort, and tooth brushing. An increasing level of depression was associated with decreasing subjective oral health level (1.34 times), uncomfortable chewing (3.08 times), and frequency of toothbrushing after lunch or before going to bed (1.23 times and 1.58 times, respectively). Conclusions: Our study confirmed a close relationship between oral health and mental health. In developing health programs for improving depression, appropriate oral health care should be considered.

Objectives: This study aimed to determine the relationship between hours of smartphone use and oral disease symptoms in Korean adolescents. Methods: In this study, data from the 2022 Youth Health Behavior Online Survey were used. The final analysis was conducted on students who responded that they have used a smartphone (N=50,375). Chi-squared test and multivariate logistic regression analysis were used to analyze the relationship between oral disease symptoms and smartphone use time (p<0.05). Results: Consequent to examining the effect of smartphone use on oral disease symptoms, it was found that oral symptoms, such as pain during chewing and tingling throbbing, increased as smartphones were used for >4 h (p<0.05). Additionally, oral symptoms, such as gingivalgia bleeding and bad breath, appeared to increase as smartphones were used for >6 h (p<0.05). However, using smartphones for <0-2 h or 2-4 h had no effect on oral disease symptoms. Conclusions: In adolescents, oral disease symptoms increased significantly with increasing hours of smartphone use. Therefore, adolescents should be guided so that they use smartphones for <2 h or >4 h. Moreover, guidance on forming the habit of tooth brushing after eating food should be provided to prevent oral disease symptoms.

A survey was conducted to study the influence of socia-demographic factors on health-related behaviors. from June 1 to July 31, 1996. The study population was 1,903 adults in Kyongju City. A questionnaire method was used to collect data. Health-related behaviors included 24 items for men and 26 items for women. The followings are summaries of findings : The compliance of health promotion activities was higher when the age was older in men, when married, when having no religion and when the education level was higher than the other groups. And it was significantly higher when the income was lower in men and higher in women, in the residents living in apartment, in white collar workers, in the chronic ill people and when the body weight was lower than the other groups. Notable differences were found in the composition of health behavior factors for socio-demographic characteristics. Men used more tobacco, coffee and tea, salt and alcohol than women. However, the practice rates of regular exercise and physical examination were higher in men than women. On the other hand, the practice rates of fruit/vegetable intake, milk drinking and regular tooth brushing were higher in women than men. When the age was old, the amount of fruit/vegetable intake, the frequency of physician visit and health check-up, and regularity of meal were increased. When the income was high, the use rate of seat-belts, the amount of coffee, milk, fruit/vegetable and red meat intake were increased. The frequency of regular exercise. tooth brushing, health check-up, pap test and breast self examination were higher in the rich than the poor. When the education level was high, the frequency of regular exercise and tooth brushing, and the use rate of seat belts were increased, and the amount of alcohol consumption and salt intake were decreased. These findings suggest that socio-demographic factors are significantly associated with the patterns of health behaviors. In conclusion public health programs and individual counseling efforts should be multifaceted and behavior-specific to encourage to practice healthy life-style.

The purpose of this study was focus on development of educational objectives by using oral health education in the elementary school from now on. Based on the results of analysis compared with a model of educational objectives and contents by reflecting the programs for analysis were the oral health education programs of the Ministry of health and social Affairs in Korea, and the programs of two states in u.s. in order to construct goals and contents of oral health education in school. The results in this study can be arranged as follows: First, an analysis on the educational objectives of dental health education program resulted that, from a viewpoint of Bloom's taxonomy of educational objectives, in case of domestic, most learning objectives expressed in the handbook of Ministry of Health and social Welfare were given too much emphasis to the cognitive domain of 37 an items in all. Affective domain were appeared the lack of balance of the development domain. Second, the result of analysis for the programs of two states of America, the cognitive domain were the most abundant of 48 an items in all, and were not significantly different to those of Korea in the form of objectives domain or statement. However a big different was shown that they organized the same objectives domain as a pattern of repeating and deepening at every grade. Third, in this study, 10 educational objectives of dental health education were established, based on the result of analyzing those existing educational programs as central figure. Those are oral cavity, brushing, nutrition of teeth, fluoride, flossing, teeth injury, dental decay, periodontal disease, malocclusion, routine dental visits. And general objectives and specific objectives of each learning area were stated and arranged grade by grade.

Background: This study aimed to investigate allergic rhinitis and the relationship between allergic diseases, such as asthma and allergic rhinitis, and dental caries and periodontal disease using the raw data from third year of the 6th Korean National Health and Nutrition Examination Survey. Methods: A total of 3,729 subjects aged over 30 years who underwent examination for allergic diseases and an oral health checkup were selected. The data were analyzed using SPSS IBM SPSS ver. 25.0 (IBM Corp., USA). Composite sample cross correlation and composite sample logistic regression analyses were performed using the composite sample general linear model. Results: On examining the socioeconomic characteristics of the subjects suffering from allergic disease and the relationship between allergic disease and oral health, allergic rhinitis was more frequently found in younger subjects with a higher level of education. Periodontal disease and dental caries were more frequent among female, older age groups, lower income earners, and subjects with a lower level of education (p<0.05). On examining the relationship between the oral health characteristics of the subject and allergic diseases and oral health, allergic rhinitis was more common in subjects with a good oral health status perception than those who answered "bad" to the oral health status question. The community periodontal index of treatment needs (CPITN) score was higher in subjects who answered "poor" to the oral health status question, lower frequency of brushing, and higher in subjects using secondary oral hygiene products; the decayed, missing and filled teeth (DMFT) index was higher in subjects with a perception of poor oral health status (p<0.05). The DMFT index was high in the asthma group, and the CPITN score was high in the group who answered "no" to allergic rhinitis. Conclusion: There is a relationship between asthma and allergic rhinitis and the DFMT index and CPITN score. Corresponding oral programs for allergic patients need to be developed.
