Aims and Scope Journal of Korean Society of Dental Hygiene is published using an open access publication model. The aim of Journal of Korean Society of Dental Hygiene is to provide a professional and scientific knowledge in the field of oral health and dental hygiene. The ultimate goal of journal of Korean Society of Dental Hygiene is to develop improving the clinical field and community with evidence-based practices to promote the oral health. The journal welcomes original research, reviews and case reports on dental hygiene theory, practice, education, and administration. About the journal Journal of Korean Society of Dental Hygiene is the official journal of the Korean Society of Dental Hygiene. Abbreviated title is 'J Korean Soc Dent Hyg'. It was launched in 2000 'J Korean Acad Dental Hygiene Education'. The English title 'The Journal of Korean Society of Dental Hygiene' was changed in 2010(Vol.10, No.3). Journal of Korean Society of Dental Hygiene is a peer-reviewed, research journal devoted to publication of a wide range of research that will inform the practice of dental hygiene. The editors invite creative research papers in dental hygiene theory, practice, education, and administration. This journal is published 6 times per year (February, April, June, August, October, and December). Full texts both in XML and PDF are freely available from http://www.jksdh.or.kr.

Objectives: To compare and evaluate the degree of abrasion of the denture base resin according to the type of denture cleansers. Methods: Denture base resin specimens were prepared and dried.
The resin specimens were installed in the automatic brushing machine so that the toothbrush weighed 200 g. The brushing was performed 1,000 times each, a total of 10,000 times using (1) distilled water (DW), (2) non-abrasive cleanser (NAC), and (3) toothpaste (TP), respectively. Thirty specimens were allocated for each group. The thickness of abrasion by brushing was calculated by converting the weight of the specimen. Results: In all DW, NAC, and TP groups, significant differences were found in the average amount of abrasion of the resin specimen due to 1,000 to 10,000 brushings (p<0.001). The average abrasion amount of the resin specimen due to brushing 10,000 times was 2.31±1.20 μm in DW group, 2.52±0.25 μm in NAC group, 6.50±0.60 μm in TP group, and the amount of abrasion in the TP group was statistically significant compared to other groups (p<0.001). Conclusions: The use of TP is not recommended as a method for maintaining the longevity of dentures and for oral health, and NAC was considered to be possible to be used as a denture cleanser because it had a similar amount of abrasion of that of DW.
Objectives: This study aimed to investigate the association between interpersonal relationships and the 4C core competencies of dental hygiene students. It also examined how interpersonal competence can be enhanced by the development and application of programs so that the 4C core competencies of university students can be improved. Methods: A survey was conducted from March to May 2019 on students from the Department of dental hygiene in Busan, South Korea, and 177 valid responses were analyzed. The general characteristics of the students were calculated using frequency and percentage, and their degree of 4C core competencies and interpersonal abilities were expressed as means (±standard deviation). Multiple regression analysis was used to analyze the effects of interpersonal competence on the 4C core competencies. Results: The findings revealed the factors affecting the 4C core competencies as; (a) communication ability was affected by interpersonal cognition and confidence building; (b) critical thinking ability was affected by person-oriented, self-expression, and confidence building; (c) creative problem-solving ability was affected by self-confidence, person-orientation, self-expression, and confidence building, and (d) cooperative self-efficacy was affected by person-oriented and confidence building. Conclusions: Based on the above findings, it is necessary to develop systematic program items and education systems that can effectively develop interpersonal competency, and thereby improve 4C core competencies among students.
Objectives: The aim of this study was to investigate the effect of breastfeeding on the occurrence of early childhood caries in Korean infants and toddlers. Methods: Data on oral examinations of infants and toddlers of the National Health Insurance Service were analyzed. The study subjects were children who participated in both the first, second, and third oral examinations and the first general health examination in 2008-2017 (n=142,185). Based on the responses to the questionnaire, the subjects were classified into breastfeeding, formula feeding, and mixed feeding groups. The participants were monitored for the development of early childhood caries in three sequential oral examinations. Results: Based on the oral examination results conducted at 54-65 months old, the decayed-filled teeth index of the breastfeeding group was the highest (2.03±3.08), followed by the mixed (1.96±3.03) and the formula feeding groups (1.82±2.91). The Cox proportional hazard regression model including all the variables showed that the risk of developing dental caries was significantly lower in the formula (hazard ratio [HR], 0.85) and mixed feeding groups (HR, 0.91) than in the breastfeeding group. Conclusions: Breastfeeding children have a higher risk of early childhood caries; therefore, oral hygiene education and regular dental check-ups are necessary.
