This study analyzed parents’ perceptions of pediatric dentistry and pediatric dental specialists, identified factors influencing their choice of dental practice for children, and compared perceptions between those with and without pediatric dentistry experience. A nationwide online survey (February 15 - 19, 2024) was conducted among 500 parents of children aged 15 years or younger: 170 from Seoul/Gyeonggi/ Incheon, 100 each from Chungcheong, Gyeongsang, Jeolla, and 30 from Gangwon. Data covered demographics, factors influencing dentist selection for children, awareness of pediatric dentists, and insights on whether parents had visited a pediatric dentist. 75.6% had visited a pediatric dental clinic, and 49.6% recognized pediatric dental specialists. Among visitors, 59.5% were aware of pediatric dental specialists, compared to 18.9% of non-visitors. Furthermore, 90.7% of parents aware of pediatric dental specialists had visited a clinic, versus 60.7% of those unaware. The highest visit rates were among parents with three children, especially aged 7 - 9. Awareness of pediatric dental specialists was highest among parents in their 20s, living in Gangwon, Seoul, Gyeonggi, and Incheon regions, with professional occupations and household monthly incomes of 7.5 - 8.5 million won. Parents with experience visiting pediatric dental clinics prioritized dentists’ expertise; those without experience prioritized short waiting times. Prior experience with pediatric dental clinics significantly increased the intention to revisit and reduced hesitation. Improving parents’ perceptions of pediatric dentists enhances decision-making and accessibility for children’s specialized dental care. Professional associations must raise awareness of pediatric dentistry. Pediatric dentists should prioritize expertise and advance their specializations in pediatric orthodontics.

Background: Considering the interactions between heavy metals, a comprehensive evaluation of the effects of exposure to various types of co-interacting heavy metals on health is required.This study assessed the association between dyslipidemia markers and blood mercury, lead, cadmium, iron, zinc, and nickel levels in residents of an abandoned refinery plant. Methods: A total of 972 individuals (exposed group: 567, control group: 405) living near the Janghang refinery plant in the Republic of Korea were included. Blood mercury, lead, cadmium, iron, zinc, nickel, cholesterol, and triglyceride levels were measured. The combined effect of the six heavy metals on dyslipidemia markers was evaluated using a Bayesian kernel machine regression (BKMR) model and compared with the results of a linear regression analysis. The BKMR model results were compared using a stratified analysis of the exposed and control groups. Results: In the BKMR model, the combined effect of the six heavy metals was significantly associated with total cholesterol (TC) levels both below the 45th percentile and above the 55th percentile in the total population. The combined effect range between the 25th and 75th percentiles of the six metals on TC levels was larger in the exposed group than that in the total population. In the control group, the combined effects of the changes in concentration of the six heavy metals on the TC concentration were not statistically significant. Conclusion These results suggest that the cholesterol levels of residents around the Janghang refinery plant may be elevated owing to exposure to multiple heavy metals.
