Objectives: The purpose of this study is to investigate the trend of dental caries inequalities according to the household income level of children and adolescents, using data from Wave 4 (2007-2009) to Wave 7 (2016-2018) of the Korea National Health and Nutrition Examination Survey (KNHANES).
Methods: The raw data were obtained from the website of KNHANES. The data by year within each wave were integrated and used for the analysis. In accordance with the guidebook for data users, the experience rate and prevalence rate of dental caries in primary and permanent teeth were estimated. Additionally, the absolute difference (AD) between the lowest and highest household income levels and the prevalence ratio (PR) by household income level were calculated.
Results: The AD in the experience rate of dental caries showed a tendency to marginally decrease in primary teeth and moderately increase in permanent teeth. The PR was not statistically significant (P >0.05) in all waves. The AD in the prevalence rate of dental caries decreased by 5.4% and 8.2% in primary and permanent teeth, respectively. The PR in Wave 7 showed that all statistical significance disappeared (P >0.05).
Conclusions: In Korean children and adolescents, dental caries inequalities by household income level showed a tendency to gradually decrease in primary or permanent teeth, and statistical significance was no longer confirmed.

Objectives: The purpose of this study was to analyze the inequality trends in self-rated poor oral health, chewing discomfort, and speaking discomfort of adults according to the household income level using data from the Korea National Health and Nutrition Examination Survey (KNHANES).
Methods: Data from 2007-2020 were downloaded from the KNHANES website and were integrated by year within each wave. The participants were 19 years old or over who responded to the oral health items of the questionnaire survey. Prevalence of self-rated poor oral health, chewing discomfort, and speaking discomfort were estimated according to the guidebook for data users. The age standardized rates were computed using the 2005 standard population. Absolute difference (AD) between the lowest and highest household income levels and the prevalence ratio (PR) as relative ratio were calculated.
Results: The prevalence of self-rated poor oral health decreased by 14.0%, but the AD increased by 3.0%, and the PR was enlarged in the lower household income level group. The prevalence of chewing discomfort and speaking discomfort decreased by 12.5% and 4.8%, respectively, but the AD of the two indicators persisted, and the PR was enlarged in the lower household income level group.
Conclusions: Self-rated oral health and oral health-related quality of life have improved overall over the past decade in Korean adults, but the severity remains, and the problem of equity has persisted or aggravated. Therefore, it is necessary to find an upstream approach to resolve the inequality in oral health in Korea.

Objectives: The study aims to investigate the influence of oral health service experience on oral health behavior of North Korean defectors and contribute to the development and implementation of oral health education among this population.
Methods: A self-reporting questionnaire survey was conducted with 161 North Korean defectors in Hanawon from April, 2015 to September, 2015. Of these participants, 50 were excluded owing to insufficient questionnaire data. The questionnaire was developed based on the WHO's Oral Health Survey (OHS) and the Korean National Oral Health Survey (KNOHS). Three categories were included in the questionnaire: demographic characteristics, dental service experience in North Korea, and oral health behavior.
Results: Males had higher levels of perceived oral health compared to females, with differences according to the region they are from in North Korea. Those who received tooth brushing instruction in North Korea showed a greater tendency to practice tooth brushing after lunch, while those who received oral health examination showed a higher level of use of oral rinses. Further, the experience of dental scaling significantly influenced both practicing tooth brushing after lunch and use of oral rinses.
Conclusions: This study confirmed that the previous experience of oral health service in North Korea positively influenced current oral health behavior of North Korean defectors. Continued oral health education can enhance their oral health behavior, oral health, and quality of life. Thus, it is suggested that policies and oral health education should be developed according to their characteristics and oral health service experience in North Korea.

Objectives: International students attending Korean universities are sometimes not able to receive timely dental treatment, despite the need for dental treatment owing to various oral health problems. The purpose of the study was to identify various barriers to the regular use of dental services by international students in a metropolitan area of Korea.
Methods: Questionnaires, both online and offline, were sent to 500 foreign university students enrolled in five selected universities located in Daegu city and nearby areas, with a total of 19 valid responses received. The questionnaire consisted of 41 items, including demographic characteristics, oral hygiene-related behavior, barriers to dental services access, and Oral Health Impact Profile (OHIP-14). The internal validity of each factor was 0.8 or higher (Cronbach Alpha α=0.86), confirming the reliability. All data were analyzed using IBM SPSS for Windows ver. 25.0 was used for analysis, and the statistical significance level was set to 0.05%.
Results: Among the international student participants, 69.5% did not visit the dentist during their stay in Korea, and those with low prevalence of gum bleeding and plaque were more likely to visit the dentist regularly. Financial problems and lack of knowledge and interest in oral health were significantly associated with the use of dental services. The revised model's explanatory power was 20.3%.
Conclusions: In order to improve the oral and general health of international students residing in Korea, university level oral health education programs, oral health care centers, and governmental support programs should be implemented.

Objectives: Oral streptococci play a significant role in the development of dental caries. Among them, Streptococcus mutans and Streptococcus sobrinus are the principal causative agents of dental caries. Rheum palmatum is a flowering plant of the family Polygonaceae with several known medicinal properties. However, its effects on oral streptococci have yet to be established. Therefore, we investigated the effects of Rheum palmatum for its potential use as an anticaries agent in inhibiting the growth of streptococci and preventing biofilm formation.
Methods: Rheum palmatum extract was diluted with sterile distilled water to obtain various extract concentrations. Several strains of oral bacteria, including S. mutans and S. sobrinus, were treated with the varying concentrations. The effects of the extract on bacterial growth was examined using the viable cell count method. Glucan synthesis was measured using a spectrophotometer at 650 nm optical density. Crystal violet staining was also carried out to observe the effect of the extract on biofilm formation.
Results: The growth of S. mutans and S. sobrinus was significantly inhibited by the Rheum palmatum solution at concentrations of 0.3% or more compared to the control group. The viable cell count results indicated that the number of bacterial colonies decreased 1.2-fold and 1.7-fold at concentrations of 1.25% and 2.5%, respectively, compared to the control group. Biofilm formation by S. mutans and S. sobrinus was suppressed more than 20-fold compared to the control group at extract concentrations of 1.25% or more.
Conclusions: The extract inhibited the growth of caries-causing bacteria, namely S. mutans and S. sobrinus. Furthermore, the extract inhibited the synthesis of glucan and biofilm formation by S. mutans and S. sobrinus. Therefore, this study suggests that the extract is a potential candidate as a therapeutic agent for controlling dental caries.

Objectives: This study aims to determine whether National Health Insurance dental implant coverage increased instances of tooth extraction in older adults.
Methods: Three periods were identified to analyze dental implant uptake in older adults-pre-coverage, intermediate-coverage, and post-coverage. Data for analysis were obtained from two sources. Frequency of tooth extraction and dental treatment data were obtained from the Healthcare Bigdata Hub. Data on the dental health status of older adults were obtained from National Health and Nutrition Examination Survey.
Results: In 2019, the National Health Insurance supplied 10.2 dental implants per 100 older adults in Korea. The frequency of tooth extractions increased slightly after dental implant coverage for older adults, but statistically, the number of missing teeth was significantly reduced. Dental caries indices in older adults were also exacerbated during this period. The DMF rate and DMFT index for older adults increased significantly. However, the illness rate due to dental caries was also reduced. There was no significant difference in the prevalence of periodontal diseases. Based on the National health data and the frequency of related services, the slight increase in tooth extractions may be due to increased utilization of dental services.
Conclusions: The authors could not find clear evidence that dental implant coverage increased the frequency of tooth extraction in older adults.

Objectives: This study aims to seek positive measures for students in a dental hygiene program to adapt well to college life by analyzing the effects of their adult attachment styles and social support on their adaptation to college life.
Methods: Data were collected from June 1 to August 30, 2021. It was conducted with a self administered questionnaire. In consideration of the dropout rate, the study recruited 200 participants. Data analysis was performed using IBM SPSS Statistics for Windows, Version 22.0.
Results: Regarding correlations with adaptation to college life, the analysis revealed positive correlations for adult attachment styles and social support. Significant correlations were seen in the following factors affecting adaptation to college life: satisfaction with college life_dummy 2, satisfaction with major_dummy 1, and adult attachment styles. The factor with the strongest effect (35.7%) on adaptation to college life was adult attachment styles.
Conclusions: Factors affecting college life adaptation were found to affect college life adaptation as college life satisfaction, major satisfaction, and adult attachment type increased. System support is needed to develop a counseling program tailored to college life by adult attachment type to increase college life satisfaction and major satisfaction.

Objectives: This study aimed to analyze the trends of the gap in toothbrushing and dental care according to the household income level of all people using the Korea National Health and Nutrition Examination Survey (the KNHANES) data.
Methods: Data from 2007-2020 were downloaded from the KNHANES website. Data integration and analysis were conducted for each wave. The prevalence of toothbrushing less than twice a day, toothbrushing after lunch, unmet dental care needs, regular dental check-ups, and preventive dental services use were each estimated based on the data users' guidebook. The absolute difference (AD) between the lowest and highest income level and the prevalence ratio (PR) were calculated.
Results: The prevalence of toothbrushing less than twice a day and toothbrushing after lunch improved by 5.3% and 13.6%, respectively. However, AD decreased by 4.5% and 2.4%, respectively. The step-wise social gradient in the PR of these indicators was maintained. The prevalence of unmet dental care needs improved substantially from 38.7% in Wave 4 to 21.0% in Wave 7. However, AD and PR were the poorest in Wave 7. The prevalence of regular dental check-ups and preventive dental service use improved steadily by Wave 8 to 45.0% and 37.0%, respectively. However, AD in Wave 8 was ―16.8% for the prevalence of regular dental check-ups and ―12.2% for preventive dental service use. The social gradient in the PR was maintained.
Conclusions: While toothbrushing and dental care use have improved over the past decade, disparity by income level has not been noticeably reduced. This study's results also reflected the achievements and limitations of the Korean government's policies and projects for toothbrushing and dental hygiene habits.

Objectives: This study aimed to evaluate the effect of silver fluoride (AgF) on the formation of cariogenic biofilm and surface of dentin in vitro.
Methods: Bovine dentin specimens with artificial caries were prepared and divided into 3 groups: untreated control, AgF-treated, and silver diamine fluoride (SDF)-treated. Streptococcus mutans cultured in brain heart infusion (BHI) broth was used to induce biofilm. The specimens were placed in a well plate containing BHI broth and S. mutans bacterial suspension, and incubated under aerobic conditions supplemented with 5% CO2 at 37℃ for 24 hours. After the incubation, the specimens were washed twice with phosphate-buffered saline (PBS) and sonicated to obtain a bacterial suspension. The diluted bacterial suspension was then smeared on a blood agar plate and cultured for 72 hours at 5% CO2 and 37℃. Following this, the number of bacterial colony forming units (CFUs) was counted and converted into logarithms for analysis. Additional specimens of each group were observed by scanning electron microscope (SEM). Energy dispersive X-ray spectroscopy (EDS) was also performed for component analysis of the dentin surface.
Results: The number of S. mutans bacterial CFUs was significantly lower in the AgF and SDF groups than in the untreated control group. It was shown that SDF inhibited biofilm formation more than AgF; however, there was no statistical significance. The SEM images showed particles formed after AgF and SDF application were deposited on the dentin. It is confirmed through EDS analysis that the particles contained silver and fluoride ions.
Conclusions: This study confirmed that AgF application effectively inhibited the formation of the early S. mutans biofilm. It is suggested that AgF solution may be effectively used in the clinical setting to prevent caries without occurrence of gingival irritation or bad odors.

Objectives: This study aimed to identify the socioeconomic factors related to tooth brushing behavior among adults in Korea.
Methods: This cross-sectional study used data from the Korea Community Health Survey (KCHS) in 2019. Respondents aged 19 years and older (n=299,099) comprised the study sample. The dependent variable was tooth brushing behavior, whereas the independent variables were demographic and socioeconomic factors. The data were processed using chi-squared test, independent t-test, ANOVA, and adjusted multiple logistic regression analysis were performed. Statistical analysis was performed using the STATA 17.0 program, with significance set at the 5% level.
Results: About half (55%) of the respondents brushed their teeth at least twice a day. The findings also revealed significant differences according to socioeconomic status (P<.01). Those who brushed their teeth less than twice a day had the following characteristics: men, aged 45 years or older, low income, working outside, less educated, without a spouse, and living in rural areas. Adjusted multiple logistic regression analysis showed that the area of residence contributed to tooth brushing behavior.
Conclusions: The area of residence, as well as socioeconomic status, should be considered in oral health education and intervention strategies.

Objectives: The purpose of this study is to investigate the trend of dental caries inequalities according to the household income level of children and adolescents, using data from Wave 4 (2007-2009) to Wave 7 (2016-2018) of the Korea National Health and Nutrition Examination Survey (KNHANES).
Methods: The raw data were obtained from the website of KNHANES. The data by year within each wave were integrated and used for the analysis. In accordance with the guidebook for data users, the experience rate and prevalence rate of dental caries in primary and permanent teeth were estimated. Additionally, the absolute difference (AD) between the lowest and highest household income levels and the prevalence ratio (PR) by household income level were calculated.
Results: The AD in the experience rate of dental caries showed a tendency to marginally decrease in primary teeth and moderately increase in permanent teeth. The PR was not statistically significant (P >0.05) in all waves. The AD in the prevalence rate of dental caries decreased by 5.4% and 8.2% in primary and permanent teeth, respectively. The PR in Wave 7 showed that all statistical significance disappeared (P >0.05).
Conclusions: In Korean children and adolescents, dental caries inequalities by household income level showed a tendency to gradually decrease in primary or permanent teeth, and statistical significance was no longer confirmed.

Objectives: This study aimed to evaluate the effects of a toothpaste containing sodium pyrophosphate and a high concentration (1,450 ppm) of fluoride on dental plaque, gingivitis index, and calculus index in a clinical trial.
Methods: This study used an eight-week, randomized, double-blinded, controlled, comparative, parallel design. The participants, who voluntarily signed a consent form, were screened through visit evaluation if they met the selection/exclusion criteria. After a one-week run-in period, the selected participants were randomly assigned to either an experimental or control group in the order of their enrollment. Subsequently, the participants were asked to brush their teeth with the study toothpaste using the rolling method for 3 min, thrice daily, for 8 weeks. Oral examinations were performed at baseline and after 3 weeks, 4 weeks, and 8 weeks. Evaluation of papillary marginal attachment index (PMA index), Talbott's gingival index, patient hygiene performance index (PHP index), Turesky plaque index, and calculus index were performed during the oral examination.
Results: After 8 weeks, the PMA indices were 7.12 for the control group and 5.00 for experimental groups. In addition, the PHP index was 2.06 for the control group and 1.66 for the experimental group. Significant differences were observed between the control and experimental groups in all indice (P<0.05).
Conclusions: This study shows that using a toothpaste containing sodium fluoride, sodium pyrophosphate, tocopherol acetate, and dental-type silica improves dental plaque removal, reduces gingivitis, and inhibits calculus formation.

Objectives: Disabled people experience difficulties in accessing dental services. Some of them tend to rely on charity dental services due to financial reasons. The purpose of this study is to identify some of the treatment statuses of disabled people to aid in planning oral health policies.
Methods: This study analyzed the dental records of 141 patients from 2014 to 2019 in a charity dental clinic in Cheongju City. The demographic characteristics such as gender, age, area, social security, and type of disability of the patients were analyzed. Chi-square test and logistic regression analyses were performed to investigate the sociodemographic factors related to dental treatments.
Results: Within the study population, 63.1% were men and 66.0% were older, over 40 years old. The type of disabilities showed significant differences in the possibilities of having periodontal treatments. The older people showed almost four times a higher risk of experiencing dental extractions than those who were younger, even after adjustments with sociodemographic factors.
Conclusions: Among disabled people, an older age corresponds to a much higher probability of extraction, making chewing difficult and leading to the deterioration of general health. It is therefore necessary to conduct a detailed and extended national oral health survey on people with disabilities to allow for the provision of systematic support.

Objectives: The purpose of this study is to analyze the trend of inequality in dental caries, deep periodontal pockets, and severe tooth loss according to the income level of adults using data from the Korea National Health and Nutrition Examination Survey (KNHANES).
Methods: The raw data from the 4th wave (2007-2009) to the 7th wave (2016-2018) were downloaded from the KNHANES website. The analytical subjects were 19 years of age or older who completed oral examinations and were classified differently according to the prevalence characteristics of each clinical indicator. The prevalence of permanent tooth caries (19 years +), deep periodontal pockets (30 years +), total tooth loss (50 years +), and 20 teeth and over (70 years +) were estimated according to the guidebook for data users. The absolute difference (AD) between the lowest and highest income levels and the prevalence ratio (PR) were calculated. All statistical analyses were performed with STATA version 13.
Results: The prevalence of permanent tooth caries decreased by 6.7%, but the AD increased by 3.4% and the PR was statistically significant. The prevalence of deep periodontal pockets was 6-10%, but the AD increased by 1.7%, and the PR of 7th wave rapidly increased. The prevalence of total tooth loss decreased by 1.5%, but in the 7th wave, the AD and the PR rapidly increased. The prevalence of 20 teeth and over increased by 10.9%, but the AD increased by ―4.3%, and the PR was statistically significant in the first and second quantiles of all waves.
Conclusions: In Korean adults, overall oral health status has improved over the past decade, but oral health inequality according to income level has generally worsened. Therefore, policy development including intervention in social determinants is needed to reduce the oral health inequality identified in this study.

Objectives: This study aimed to evaluate the changes in clinical indexes related to periodontitis, such as malodor, gingival and plaque indexes, during the adjuvant use of a high pressure oral irrigator (COMORAL®, SMDsolutions, Seoul, Korea) in volunteers.
Methods: We recruited 17 volunteers from an advertisement posted on Dankook University's bulletin board. The oral malodor, gingival index, and plaque index of each volunteer were during the adjuvant use of a high pressure oral irrigator within a 4-week period.
Results: Routine tooth brushing was done together with the adjuvant use of a new high pressure oral irrigator in the 4-week period. The oral malodor, gingival index, and plaque index measured after 2 and 4 weeks of use significantly decreased (P <0.05) compared with the baseline values obtained before the start of the study.
Conclusions: The adjuvant use of a new high pressure oral irrigator with routine tooth brushing in volunteers may more effectively manage daily oral hygiene.

Methods: The online survey results, obtained from 307 respondents, were statistically analyzed using frequency analysis, t-test, one-way ANOVA, and multiple regression analysis with the IBM SPSS 20.0 software.
Results: The factors affecting the technology portion of digital literacy included age (P <0.001), years in career (P <0.001), number of personnel in workplace (P =0.009), level of education (P =0.001), region of workplace (P =0.002), and form of workplace (P =0.021). The factors affecting the application portion of digital literacy included age (P <0.001), years in career (P =0.009), and number of personnel in the workplace (P =0.008). The level of occupational self-efficacy positively affected the technology portion of digital literacy, while organizational commitment positively affected the technology portion and negatively affected the application portion of digital literacy.
Conclusions: Although this study has limitations, it carries significance as a survey of dental hygienists' digital literacy standing. To adapt to and function in the current society of digital informatics, ongoing education and research on digital literacy are warranted.
