Objectives: This study was conducted to understand the research trends in dental hygiene, domestically and internationally. Methods: The Journal of the Korean Society of Dental Hygiene (JKSDH) examined 1,689 articles, totaling 7,575 words, whereas the International Journal of Dental Hygiene (IJDH) reviewed 1,089 articles, totaling 10,194 words, employing a semantic network and CONCOR analysis. Results: Findings indicated that centrality analysis revealed that the top 10 most frequently used words in journals exhibited high scores in degree, betweenness, and closeness centralities. CONCOR analysis identified four clusters within the JKSDH; ‘oral health program’, ‘professionalism of dental hygienists’, ‘oral health assessment’ and ‘dental hygienist work environment’. The four categories of IJDH were ‘managing periodontitis’, ‘managing systemic diseases’, ‘oral health assessment’ and ‘oral health prevention initiatives’. Conclusions: Future dental hygiene research in Korea should focus on evidence-based practices that can serve as a foundation for enhancing the professionalism of dental hygienists through a unique knowledge system in the field.

Objectives: This study aimed to compare the characteristics of partial dentures supported by dental implants and to analyze related factors to provide data. This data can serve as a basis for oral health-related insurance policies for the elderly. Methods: Using data from the 8th National Health and Nutrition Survey, we analyzed the data from 4,304 individuals aged ≥65 years. Based on the Andersen behavioral model, we set the antecedent, possible, and necessary factors as independent variables. We performed logistic regression analysis with dental implants and partial dentures as dependent variables. Results: Implant possession was affected by male sex, younger age, higher education, income levels, and healthy lifestyle habits. In contrast, partial denture possession was affected by older age, lower education and income levels, unhealthy lifestyle habits, and chewing discomfort. Conclusions: The factors affecting the possession rates of dental implants and partial dentures demonstrated opposite trends. Implants were more affected by health behaviors, whereas partial dentures were more affected by socioeconomic factors. Therefore, a policy to expand the dental coverage must establish a differentiated strategy that considers the characteristics of each type of prosthesis.

Objectives: The aim of this study was to identify and compare the properties associated with the biofilm-forming abilities of bacteria isolated from water in dental unit waterlines (DUWLs). Methods: Twelve bacterial strains isolated from the output water of DUWLs were cultured in 12-well plates containing polyurethane tubing and R2A medium. The amount of biofilm formed by each strain was evaluated. Based on the amount of biofilm formed, three strains were selected, and the level of adhesion was determined for each strain depending on the inoculation concentration and incubation time. In addition, adhesion inhibitors were identified in the three strains, and their hydrophobicity and extracellular polymeric substances (EPS) formation were compared. Results: Among the 12 strains, the highest levels of biofilm accumulation were seen in Cupriavidus pauculus HY12. C. pauculus HY12 showed higher levels of adhesion at lower bacterial concentrations and shorter incubation times than other strains. The adhesion of C. pauculus HY12 was inhibited by trypsin. Among the three isolates, hydrophobicity and EPS production were the highest in Acidovorax delafieldii HY1. Conclusions: The results of this study provide a basis for understanding the mechanism of DUWL biofilm formation and the development of methods to inhibit biofilm formation.
