Ji-A Park , Sol Han , Bo-Hyoung Jin

Abstract : Objectives: This study aims to suggest ways to improve the oral care competencies of caregivers by strengthening oral care services for the elderly with mobility difficulties in long-term care facilities.Methods: Through a web survey, 215 caregivers were invited, their actual situation was identified, and necessary educational tasks were listed. We developed 16 types of card news, two types of songs, and four types of video clips that can be used in the field for the listed educational topics. Several meetings with expert developers resulted in developing the components and design of an oral health management platform for caregivers in long-term care facilities.Results: As a result of the web survey, many caregivers in long-term care facilities needed education or information on oral care methods, and many people felt difficulties in oral care for the elderly. About 40% of the caregivers had no experience in oral health education, and many learned how to care through unsystematic apprenticeships. Most of the education content that caregivers prioritized were brushing teeth and denture management, but there were also needs such as management of dementia and bedridden patients, non-cooperative oral care, nutrition management, and oral auxiliary products use.Conclusions: In conclusion, this study reviewed and suggested digital platforms such as strengthening caregivers’ competency in long-term care facilities, providing customized educational information, discovering oral problems of the elderly, and reporting oral difficulties to experts.

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

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

Boo Young Choi , 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.

Ja-Young Na , 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.

Su-Yeon Hwang , 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.
