, Ji-Eun Kim , Ki-Ho Chung et al.Abstract : Objectives: To investigate the effect of commercially available hard seltzer on the tooth enamel surface. Methods: Some commercially available hard seltzer were purchased at the market and the characteristics of the beverages were surveyed. Subsequently, Cloud hard seltzer mango was selected for the hard seltzer group (group 4), Jeju Samdasoo for the mineral water group (group 1), Coca-Cola for the cola group (group 2), and Cloud Original for the beer group (group 3). The specimens were immersed in the experimental beverage for 30 minutes, then the surface microhardness and surface condition of the specimens were evaluated. Results: The average pH of the twelve types of hard seltzer in this study were 3.51±0.01 (before stirring) and 3.46±0.01 (after stirring). The pH of experimental beverage were 7.92±0.03 (group 1), 2.55±0.01 (group 2), 4.41±0.01 (group 3), and 3.31±0.01 (group 4). Paired t-test of the surface microhardness of enamel before and after beverage immersion found no significant difference in group 1 (P>0.05), but a significant difference was observed in groups 2, 3, and 4 (P
, Hyo-Won Oh , Jae-Gyu Jeon Abstract : Objectives: The purpose of this study was to determine the influence of carbonated drinks on acid production in Streptococcus mutans biofilm. Methods: Fifty one hour-old S. mutans biofilms were formed on hydroxyapatite discs. After selecting of the carbonated drinks (Coca cola, Coca cola zero sugar, Sprite, Sprite zero sugar, and Fanta), as well as negative (water) and positive (1% sucrose) controls for this study, glycolytic pH drop assay was performed using the S. mutans biofilms. The influence of the test agents on acid production of the 51 h-old biofilms was determined by the initial production rate and final concentration of protons, calculated using the pH values at 0-30 min and 120 min, respectively. Results: The pH values of the carbonated drinks ranged from 2.4 to 3.1. Sugar-free carbonated drinks and the negative control maintained the pH of acid produced by S. mutans biofilms above the critical pH. The sugar-added carbonated drinks and the positive control decreased the pH below the critical pH due to the acid production of S. mutans biofilms. Overall, sugar concentration in carbonated drinks was closely related to acid production in S. mutans biofilm. Conclusions: These results suggest that sugar-added carbonated beverages should be considered for their role in dental erosion and dental caries, while non-sugar-added carbonated beverages should emphasize their role in dental erosion rather than dental caries.
, Jung-Eun Park , Jong-Hwa Jang Abstract : Objectives: This study aimed to investigate the association between food insecurity and periodontitis in Korean adults. Methods: The data used for analysis were obtained from the 7th Korean National Health and Nutrition Examination Survey (2016-2018). Data were analyzed using chi-square test. Additionally, multiple logistic regression analysis was performed to assess the association between food insecurity and periodontitis. Statistical significance level was set at
, Ju-Yeon Cho , Eun-kyong Kim Abstract : Objectives: Rational planning and efficient management of the oral health workforce is essential for the promotion of oral health. Therefore, this study aims to analyze the distribution characteristics of dentists, using public big data. The results of this study could contribute to the development of the oral healthcare policies proposal and desirable dental services. Methods: The data of dentists working in medical institutions were analyzed by type and region from 2010 to 2020 using the Korean Statistical Information Service. Python version 3.10 was employed for data analysis and visualization, and the matplotlib and seaborn libraries were used to create graphs. Results: The average age of dentists working in medical institutions was 47.4 years in 2020 ― an increase by 5.3 years compared to the 2010 data. When considering different regions, the average age of dentists in major cities, including Seoul (49.7 years), was higher than in their surroundings areas (47.2-49.5 years). Conclusions: A continuous increase in the average age of dentists over the past 10 years and a difference in age distribution among different regions were observed. This is probably because new dental clinics are opening predominantly in smaller cities. Therefore, institutional support for new dental clinics in these areas is necessary to promote high-quality dental healthcare within regions. Additionally, oral healthcare services to vulnerable populations should be provided through a national oral healthcare policy utilizing these local dental clinics.
Abstract : Objectives: The purpose of this study was to analyze the risk factors for dental caries and severe periodontitis using the data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES) for improving the lifestyle risk assessment and oral health education in national adult dental examination program. Methods: The participants included 7,301 adults aged 19-59 years for dental caries analysis and 4,886 adults aged 40-59 years for severe periodontitis analysis. Self-care of oral hygiene (brushing teeth frequency, brushing teeth before bed, use of interdental brush or floss), sugar intake, and smoking were selected as risk factors related to oral health. The other risk factors included socio-demographic characteristics (age, gender, region, household income, education), dental care utilization (dental examination, unmet dental needs), and systematic diseases (hypertension, diabetes, high cholesterol). The association between the target diseases and risk factors was analyzed using a complex samples logistic regression model. Results: Dental caries was negatively associated with brushing teeth frequency, interdental brushing or flossing, sugar intake, and age; and positively associated with smoking and oral examination. Severe periodontitis was positively associated with smoking, diabetes, age, and region (eup/myeon). Gender (male), household income (low), and unmet dental care (yes) were positively associated with dental caries or severe periodontitis. Conclusions: It was possible to obtain evidence of lifestyle factors (self-care oral hygiene, sugar intake, smoking) affecting the target disease (dental caries or periodontal disease) for the national adult dental examination program. However, there were limitations in estimating causality as this was a cross-sectional study, and the explanatory power of the risk model was low. Therefore, it is necessary to conduct a cohort study of the adult dental examination program to obtain a higher level of evidence on the risk factors of the target diseases.
, Heung-Soo Lee , Hyo-Won Oh Abstract : Objectives: The purpose of this study was to analyze the pattern of dental caries in 12-year-old Korean adolescents through multivariate analysis. Methods: This study used raw data from the 2015 Korea Children’s Oral Health Survey. The study participants were 12-year-old adolescents. A total of 27,291 people participated in the questionnaire and oral test. The statistical analysis methods used were multidimensional scaling, cluster analysis, and factor analysis. Results: The result was derived after analyzing the dental caries pattern of teeth and tooth surface by multi-dimensional scaling method, cluster analysis method, and factor analysis. Morphologically homologous teeth were gathered to form clusters. Caries occurrence showed a more similar caries experience pattern when the types of tooth surfaces, such as occlusal and occlusal surfaces, were the same than when they were different. Conclusions: Epidemiological data on the pattern of dental caries in 12-year-old adolescents can be used as basic data to create evidence-based dental caries management plans.
, Hyeonjeong Go , Youn-Hee Choi Abstract : Objectives: Cardio-cerebrovascular diseases (CVDs) are the leading cause of death in advanced countries due to their upward-trending incidence rates. Preventing CVDs is imperative to ensure a healthy elderly life and prepare for an aging society. Considering the relationship between oral health and systemic health, effective oral health management will have an important role in preventing CVDs. This study aimed to examine the influence of oral health behaviors as risk factors for CVDs. Methods: A custom database combining data from the Korean National Health Insurance Service and the Korea National Health and Nutrition Examination Survey from 2010 to 2017 was analyzed. The study included participants aged 35 or over (n=14,492) with recorded responses on oral health behaviors. Logistic regression analyses were performed to assess the association between oral health behaviors and CVDs. Results: The CVDs group was shown to practice inappropriate oral health management. In comparison to the non-CVDs group, the CVDs group showed a significantly higher rate of 8.0% in ‘once or less’ of toothbrushing frequency (P
, Deok-Young Park , Hyun-Jun Yoo et al.Abstract : Objectives: This study addressed longstanding issues in Korea’s public health dentist system by defining and standardizing job duties. A practical job description was drafted based on job analysis results to promote work efficiency and lay the groundwork for future educational programs. Methods: The job description elements were selected and drafted based on previous studies. These drafts were revised and refined with expert panel validation. Results: The main job duties of public health dentists encompass community oral health, dental practice, public oral health research, and special oral health, tailored for institutions such as health sub-centers, health centers, health clinics, national health organizations, and correctional facilities. For community oral health at public health subcenters involves 12 key duties including projects, education, and community engagement. Public health centers/clinics focus on 16 key duties mainly around health project planning and evaluation. Dental care across both settings has 15 main duties. Public oral health research emphasizes community surveys and epidemiology. Special oral health in correctional facilities covers 11 main duties including education and external resource linking. Conclusions: It concluded that for the development of public health dentists in South Korea, it is necessary to develop public health dentist education programs to promote the performance of public health dentists and to equip them with the competencies necessary to perform such duties, focusing on job descriptions organized around the characteristics of workplaces and major tasks.
