, Choong-Ho Choi Abstract : Objectives: This study examines the relationship of dental hygienists’ professional self-concept, self-leadership, job stress, and fatigue with their clinical competence in order to identify factors that can improve clinical competence. This study is intended to provide basic information to develop educational programs for dental hygienist’s clinical competence.Methods: The self-administered questionnaire survey was conducted with 243 dental hygienists working at dental clinics in Gwangju and Jeonnam from August 14, 2017 to September 9, 2017. The data regarding the general characteristics, professional self-concept, self-leadership, job stress and fatigue, and clinical competence were collected, and analyzed through independent t-tests, one-way analysis of variance (ANOVA), Pearson’s correlation coefficient, and multiple regression analysis using the SPSS Windows ver. 22.0.Results: High professional self-concept (r=0.54) and self-leadership(r=0.48) were associated with high clinical competence. High self-leadership (r=0.53) was associated with high professional self-concept. High fatigue(r=―0.21) was associated with low professional self-concept(P
, Gil-Bok Choi , Da-Hui Kim , Ja-Won Cho , Jae-Seung Yea Abstract : Objectives: This study investigated the effects of mouthwashes containing cetylpyridinium chloride and zinc acetate on oral health.Methods: A total of 60 participants were included in the study. Fifty-three participants (27 and 26 participants in the experimental and control groups, respectively) were retained, excluding seven candidates who dropped out. The mouthwash used for the study was spat out after 10-15 ml of mouth-washing for 3 s in the oral cavity after breakfast, lunch, and dinner. Oral examination indices included the gingival (gingival index, PMA index), the patient hygiene performance (PHP index, Turesky plaque index), and the bad breath (BB checker, Oral chroma) indices. Five measurements were taken after 2, 4, 6, 8, and 12 weeks and compared.Results: Measurements of the gingival index showed a statistically significant difference between the experimental and the control groups after 4 weeks, and the PMA index from eight weeks (P
, Jung-Eun Park Abstract : Objectives: This study aims to investigate the effect of determinants on the number of remaining teeth in Korean adults using a machine learning-based decision tree analysis.Methods: The study used data from the Korea National Health and Nutrition Examination Survey (KNHANES) VII (2016-2018) and a decision-tree analysis to explain the causes for the number of remaining teeth in adults. The determinants for the study are sex, age, house income, education level, diabetes, BMI, smoking, alcohol drinking, tooth brushing per day, and periodontitis.Results: Age had the most significant effect on the number of remaining teeth, followed by house income.Conclusions: This research is meaningful as it provides a systematic index in the number of remaining teeth in Korean adults based on a combination of numerous variables. These variables have already been validated against the results of previous studies that have attempted to elucidate new variables affecting the number of remaining teeth.
, Seung-Hee Ryu , Ji-Na Lim , Hye-Jin Kwon , Zi-Lan Wang , Jae-Young Lee , Hyun-Jae Cho Abstract : This study focuses on the importance of non-face-to-face healthcare, based on the experience with the COVID-19 pandemic, and proposes a model for oral health management services utilizing personal data, known as “my data.” The model aims to develop a comprehensive system that collects and integrates individual health records for easy access. It includes assessing oral health through oral examination records and surveys, creating risk assessment algorithms tailored to various population groups, and standardizing medical terms and data. The goal is to accurately evaluate individual oral health conditions and provide personalized services. However, the success of the model requires considerations such as platform management, user experience enhancement, and medical data security. The research proposes possibilities for further investigation to enhance the oral health service model. This study introduces a novel approach to individual health management, establishing the foundation of effective health management even in non-face-to-face settings.
, Heung-Soo Lee , Hyo-Won Oh Abstract : Objectives: This study aimed to examine the effects of oral health-related self efficacy and social support on oral health-related quality of life, and analyze the related factors.Methods: A cross-sectional study was carried out on 979 high school students living in Iksan. Data were collected from January 15 to 30, 2014. Individual self-administered surveys were conducted through the sampling method. The contents of the survey were the characteristics of the subjects, oral health-related self efficacy (OHSE), social support related to oral health (OHSS), and quality of life related to oral health (QHRQoL). A survey tool designed by the author was used to measure OHSE and OHSS. QHRQoL used Child Oral Health Impact Profile-Short Form 19 (COHIP-SF 19) for examination. The statistical analysis methods used were mean difference, correlation, and multiple regression analyses.Results: QHRQol was correlated with OHSE, but not OHSS. Per the multivariate analysis, factors that affected QHRQoL were gender, mother’s education level, academic stress, and OHSE; OHSS did not have any effect.Conclusions: It was found that OHSE influenced QHRQoL. Therefore, it is necessary to develop education programs that can enhance OHSE.
, Joon-Haeng Lee , Jong-Su Kim , Jong-Bin Kim , Mi-Ran Han , Ji-Sun Shin Abstract : Objectives: The purpose of this study was to compare the fracture strength and traslucency of 3D printing resin crowns according to different thicknesses.Methods: Resin crowns were designed with CAD software and a 3D scanner, using scanned data of the #61 tooth model. Resin Crowns with different thicknesses were printed using a 3D printer, and subsequently divided into four groups according to thickness (0.3, 0.5, 0.7, and 1.0 mm). Fracture strength was compared among groups with a resin strip crown of 1.0 mm thickness. Compressive force was applied using a universal testing machine at 30° along the lingual surface at 1 mm/min cross head speed. For translucency evaluation, thin square specimens were printed of thicknesses 0.3, 0.5, 0.7, and 1.0 mm, and translucency was measured using a spectrophotometer.Results: As a result of fracture strength measurement, fracture strength increased as thickness increased, and a significant difference was observed solely between thicknesses of 0.3 and 0.5 mm, and the thicknesses of 0.3 and 0.5 mm (P
, Hyo-Won Oh , Heung-Soo Lee Abstract : Objectives: This study aimed to investigate the relationship between oral health beliefs and oral health-related dietary behavior.Methods: The participants of this cross-sectional study were 728 middle school students living in Jeonju who were selected through convenience sampling. For the survey, self-administered questionnaires were completed in individual settings. The analysis model was the oral health belief model, and the analysis method was path analysis.Results: Among oral health beliefs, perceived susceptibility, perceived severity, perceived barriers, and self-efficacy were found to be correlated with the oral health-related dietary behavior index. Multiple regression analysis showed that factors affecting the oral health-related dietary behavior index were gender (female), perceived susceptibility, perceived severity, perceived barriers, and self-efficacy. Path analysis showed that variables that significantly impact the oral health-related dietary behavior index are perceived susceptibility, perceived benefits, perceived barriers, and likelihood of action. The factor with the greatest impact was perceived barrier; the lower the barrier, the higher the level of dietary behavior undertaken to prevent dental caries.Conclusions: Oral health beliefs are related to oral health-related dietary behavior. Since perceived barriers had the greatest correlation with oral health-related dietary behavior, measures must be taken to help remove the barriers.
, 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
, Min-Ji Byon , Eun-Joo Jun , Si-Mook Kang , Seung-Hwa Jeong Abstract : Objectives: This study compares the labeling information on the sizes of interdental brushes marketed in Korea to their actual sizes. Moreover, it analyzes the relationship between the size of the passage hole diameter (PHD), brush diameter, stem diameter, and stem length.Methods: Among the commercially available interdental brushes in Korea, 171 interdental brushes, 3 in each size, were collected from 9 companies. The labels of the collected interdental brushes were researched, and the PHD was measured and compared. The correlation between the passage hole diameter, brush diameter, stem diameter, and stem length was analyzed. Multiple regression analysis was performed to verify the effect of brush diameter, stem diameter, and stem length on the determination of the PHD.Results: The sizes of the interdental brushes were expressed using the ISO labeling or the Small, Medium, Large (S, M, L) labeling and indicated in units of 0.1. The concordance rate of the measured PHD and named PHD was 39.7%. The measured brush diameter, stem diameter, and stem length increased as the interdental brush size increased. There was a significant correlation (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.
