Background
The COVID-19 pandemic changed the world and created a shift in the dental education program. This sudden change in the dental education program may have affected the academic standards of dental students. This study aimed to evaluate the overall satisfaction and effectiveness of online learning in pediatric dentistry of undergraduate dental students’ during the COVID-19 pandemic in South Korea.
Methods
An anonymous online survey was sent to three dental schools, and responses were collected from dental school students. Questions included the demographics, perspectives of online classes, comparison of online and offline pediatric dentistry classes and opinions on how dental schools are handling the pandemic. Students’ perspectives on online classes were evaluated based on satisfaction with online education. Data were analyzed using the Kruskal-Wallis test and the Mann-Whitney U test.
Results
Most students took online classes from home (80.9%) using Zoom (50.4%). The majority reported overall program satisfaction (74.1%) and agreed that universities implemented online classes well (55%). Students who were in favor of online classes responded more positively to questions on the effectiveness and safety of online learning (p < 0.05). Regardless of satisfaction with online education, the students agreed that the online education shift was the right decision in pandemic outbreak.
Conclusions
Dental students in South Korea preferred and adapted well to the web-based learning program in pediatric dentistry during COVID-19 pandemic.
The rate of preterm birth is increasing worldwide and preterm infants are susceptible to oral health problems. Hence, this study aimed to investigate the effect of premature birth on dietary and oral characteristics as well as dental treatment experiences of preterm infants using a nationwide cohort study. Data was retrospectively analyzed from National Health Screening Program for Infants and Children (NHSIC) of the National Health Insurance Service of Korea. 5% sample of children born between 2008 and 2012 who completed first or second infant health screening were included and divided into full-term and preterm-birth groups. Clinical data variables such as dietary habits, oral characteristics, and dental treatment experiences were investigated and comparatively analyzed. Preterm infants showed significantly lower rates of breastfeeding at 4–6 months (p<0.001), delayed start of weaning food at 9–12 months (p<0.001), higher rates of bottle feeding at 18–24 months (p<0.001), poor appetite at 30–36 months (p<0.001) and higher rates of improper swallowing and chewing function at 42–53 months (p = 0.023) than full-term infants. Preterm infants also had eating habits leading to poor oral conditions and higher percentage of absence of dental visit compared to full-term infants (p = 0.036). However, dental treatments including 1-visit pulpectomy (p = 0.007) and 2-visit pulpectomy (p = 0.042) significantly decreased when oral health screening was completed at least once. The NHSIC can be an effective policy for oral health management in preterm infants.
The 61st Korean Academy of Pediatric Dentistry congress was hosted online for the first time in 2020 due to coronavirus disease-19. The congress was operated using the ZOOM platform. The aim of this paper is to analyze and evaluate the overall satisfaction and feedbacks from congress participants via anonymous Google Forms online survey. A test meeting was previously organized before the actual congress to facilitate the smooth process and the participants overall showed high satisfaction. Members who participated in test meeting compared to those who did not, found it significantly helpful, which contributed overall higher satisfaction with the online congress. Abstracts were accepted from the current pediatric dentistry residents and the oral presentations were also held online for the first time. The presenters and the judges were overall very satisfied. In an unguaranteed situation of termination of coronavirus disease-19, the decision to conduct an online congress was a favorable option.
