, 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.
, Youn-Hee Choi Abstract : Objectives: This study aimed to analyze dental healthcare resources and utilization patterns according to regional characteristics in Korea and to compare disparities in unmet dental care need rates and subjective oral health status. Methods: Dental healthcare resources and utilization patterns were analyzed using data from the National Health Insurance Statistics (NHIS) and the Population and Housing Census (2022). Descriptive statistics were performed on the distribution of dental healthcare resources, such as dental institutions, dentists, and dental hygienists per 100,000 people. Inflow and outflow indices for healthcare utilization were calculated using the number of days of inpatient and outpatient visits for oral diseases. In addition, the association between the type of local governance and unmet oral healthcare needs, as well as subjective oral health status, was analyzed using the chi-square test with the Community Health Survey (2022) data. Results: The number of dental institutions, dentists, and dental hygienists (per 100,000 people) in rural areas (such as “Urban and rural complex - si,” “Gun,” and “Gun with an established public health clinic”) was lower than in urban areas (such as a “[Special] metropolitan city”). The inflow and outflow indices for healthcare utilization by oral disease indicated higher outflows of patients to metropolitan areas. Furthermore, the chi-square analysis revealed that, for the “Gun with an established public health clinic,” more respondents reported unmet dental care needs and poor subjective oral health status (P
, Hyunsook Bae Abstract : Objectives: In this study, we investigated the validity and effectiveness of biomarkers and oral microbiome analysis for evaluation of periodontal status following scaling intervention. Methods: The study included 15 participants who were selected based on inclusion/exclusion criteria. Periodontal indices, including the plaque index, probing depth, modified sulcus bleeding index, and calculus index were measured to evaluate clinical periodontal status and disease progression. Pre- and post-scaling gingival crevicular fluid (GCF) was obtained from 12-20 sites per patient to measure changes in the odontogenic ameloblast-associated protein (ODAM) concentration using an enzyme-linked immunosorbent assay. Additionally, pre- and post-treatment salivary samples were obtained for quantitative analysis of oral microbiome distribution. Results: All clinical parameters showed significant differences in pre- and post-scaling values and significant changes in the ODAM concentration in the GCF in patients with initial and moderate periodontitis. Quantitative analysis performed after scaling intervention revealed changes in eight oral disease-causing bacteria associated with periodontal disease, including Aggregatibacter, Porphyromonas, Tannerella, Treponema, Prevotella, and Fusobacterium. Specifically, Tannerella forsythia and Fusobacterium nucleatum (well-known major periodontal pathogens) numbers were significantly decreased following non-surgical periodontal therapy. However, no significant association was observed between changes in the salivary oral microbiota and ODAM concentration in the GCF, following treatment. Conclusions: Based on the findings of this study, we propose the use of ODAM protein and quantitative analysis of periodontal disease-associated bacteria as objective and quantitative biomarkers for evaluation of improvement in periodontal disease following scaling intervention.
, Ji-Hye Kim , Keun-Bae Song , Youn-Hee Choi Abstract : Objectives: This study aimed to compare each strain’s number of microorganisms found in oral samples collected using various collection methods. Methods: Twenty-two adults aged 40 and above participated in the study. Oral samples were collected from subjects using three different methods (stimulated saliva, oral biofilm, and calculus), and the collected samples were analyzed using the multiplex real-time Polymerase chain reaction (PCR) method. Results: The study included 22 subjects (2 men, 20 women) with an age range of 40-75 years. Healthy oral condition was observed in 10 subjects, while the remaining 12 had periodontitis. The saliva and biofilm collection methods for oral microorganisms detected Porphyromonas gingivalis (Pg), Tannerella forsynthesis (Tf), and Fusobacterium nucleatum (Fn), which are the causative bacteria of periodontal disease, more effectively compared with the calculus group. In addition, the saliva group showed a better ability to detect Streptococcus mutans (Sm) which causes dental caries, compared with the biofilm and calculus groups. Comparisons based on the presence or absence of periodontitis and the collection method revealed a statistically significant difference in the number of oral microorganisms only in case of Sm strain. Conclusions: The frequency of expression of certain strains varies according to the method of collection of oral microorganisms. Further, the saliva and biofilm methods of collecting oral microorganisms are more suitable for quantitative analysis of bacteria causing periodontal disease.
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 Abstract : Objectives: This study aimed to not only compare the oral health problems and behavior of daytime and shift workers but also investigate the effects of work type on oral health behavior to help improve occupational oral health policies and systems. Methods: Workers from three different workplaces in Jeollabuk-do were selected through convenience sampling. After posting a study recruitment notice, an online self-administered questionnaire (Naver form, Naver corp., Korea) was used to collect data. A total of 314 participants, including 179 daytime workers and 135 shift workers, were included in the final analysis. Results: Shift workers had a higher periodontal disease index and smoking rate compared with daytime workers (P
, Hee-Hong Min Abstract : Objectives: The purpose of this study is to understand the relationship between dental hygiene students’ empathy, interpersonal skills, and clinical practice stress, and to improve the system and skills necessary in the clinical practice process so that individuals can adapt to and perform their duties as dental hygienists in the future.Methods: From the date of approval until August 30, 2022, dental hygiene students who have experienced clinical practice were conveniently extracted. The sample size was was determined with G*power 3.1.9.7 program and 190 participants were included in the final analysis. Data analysis used the IBM SPSS Statistics 26.0 program.Results: Factors affecting clinical practice stress were found to be significantly related to empathic concern and personal distress, which are sub-factors of empathy, and the explanatory power was 19.7%.Conclusions: Based on the above findings, in order to reduce dental hygiene students’ clinical practice stress and improve their interpersonal skills and empathy, it is necessary to provide a systematic program tailored to the student level, and further, to improve the quality of clinical practice education through industry-academia cooperation.
, Sung Hee Jun , Sun Rak Jeong Abstract : Objectives: This study used data from the seventh National Health and Nutrition Survey, a dataset which signifies that dental services in the country exhibit relatively low health insurance coverage and high copay rates compared to other medical healthcare services. We surveyed the utilization rate of dental care and the prevalence of untreated conditions among Korean elders aged over 65. Furthermore, we aimed to present policy implications to improve dental care accessibility and expand health insurance coverage for elders, especially vulnerable individuals who are bedridden or living alone. Methods: We used raw data from the seventh National Health and Nutrition Survey to investigate Korean elders’ dental service utilization and untreated conditions. We opted for elders aged over 65 and finalized 1,712 subjects for the analysis. Statistical analysis was performed using IBM SPSS 25.0 (IBM Corp., Chicago, IL, USA). Groups were detailed in terms of strata of variation estimation and elders aged over 65, cluster of district enumeration, and weighted oral survey. We generated a scheme file and employed complex sampling analysis with a statistical significance level of P
, Deok-Young Park , Hyun-Jun Yoo , Byoung-Jin Lee , Sol Han , Hee-Chul Park , Bo-Hyoung Jin 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.
, Hyun-Sook Bae Abstract : Objectives: This study investigates dental hygienists’ experience, education, and awareness of dentin hypersensitivity. Its purpose is to provide a basis for the development of preventive procedures and educational materials for dentin hypersensitivity.Methods: After distributing the questionnaire, Oral health characteristics of dental hygienists and the general public were investigated. In addition, the experience of dentin hypersensitivity according to general characteristics and the need for education were confirmed. The collected data were analyzed by frequency analysis, descriptive statistical analysis, unpaired t-test, and one-way ANOVA.Results: There was no difference in the experience of dentin hypersensitivity according to oral health-related or general characteristics in the dental hygienist group. In terms of oral health, there was a difference in educational requirements for dentin hypersensitivity for ‘family support for oral health’.Conclusions: The experience of dentin hypersensitivity in this study can be used as data for the development of a Korean dentin hypersensitivity experience questionnaire. The educational requirements and perception of dentine hypersensitivity will help develop educational materials from the patient’s perspective. Moreover, they will be essential for practical education on dentine hypersensitivity in dental hygiene and educational processes.
